Lunar phase visualization contest

Lunar phase visualization contest:

Right now I’m sitting in the main ‘ballroom’* of the NASA Ames conference center. I’m here for the NASA Lunar Forums, which are hosted by the NASA Lunar Science Institute, which is housed at NASA Ames. (As one might guess, there are NASA meatballs everywhere). It is a good meeting, filled with good content, and all the latest good news from the Lunar Reconnaissance Orbiter. The multi-hat wearing Nancy Atkinson is here writing stories for Universe Today and recording podcasts for 365 days of Astronomy. I’ll leave it to her to talk science. While she’s busy doing the fun stuff, I’ve been in and out of meetings, and working to plan great (I hope!) things for the future.


Coming up on October 8, 2011 (and on TBD dates in future years) is the International Observe the Moon Night. This special event invites the world to look up and learn about the moon. This may seem like a “Yada yada yada, whatever…” kind of event, but it’s surprising how many new discoveries about the moon don’t make it into the heads of Joe six-pack and his kids. Since the 1990s, so many spacecraft have visited the moon from so many nations that I have given up keeping track of them! Yet, despite the wealth of new info, researcher Emily CoBabe-Ammann found that no available public school book contains lunar science results that come from modern exploration – everything is based on Apollo! Well, Apollo was before I was born and it’s time to change what people know about the moon.

I personally can’t change the US school system, but, with your help, I might be able to get some curiosity arousing materials into school teachers’ hands and onto cubical and household walls. Here is where you come in: Inspired by the amazing Lunar phase data visualization shown at right, we’ve decided at Astrosphere (parent non-profit of Astronomy Cast, 365 Days of Astronomy, and several other projects) that we are going to hold a lunar phase visualization contest. (And if Dimitri opted to enter, I’d love to see what he does with 2012!)


Your challenge, should you choose to accept it, is to create a calendar for 2012 that communicates the phases of the moon in a way that is interesting, beautiful, and true. Our intention is that we will print the winning poster for distribution. (We are assuming we’ll get awesome submissions, but failing that, we reserve the right to only post the winning entry online.) on the back of each material will be a fact sheet on the moon that uses modern data and images.


Complete contest rules and guidelines here: Visualize-the-Moon Poster Contest


Now, we know some of you aren’t exactly artistic, but may want to help support getting awesomeness into the hands of teacher. That’s cool, there are ways for you to help to! 1. The big thing you can do today is help get the word out. Let people know via twitter, Facebook, your blog, you sig, write it on your classroom chalkboard, and, heck, write it on your forehead (ok, maybe not that). Whatever you do, anything you can do to help get the creative people in your life engaged would be awesome. 2. Donate to Astrosphere to help pay for teaching materials to get mailed to teaches. 100% of proceeds will go to printing, postage, and admittedly paying the poor person who will stuff the audience (but he works quickly and effectively). Using your funding we will send teaches requested posters and other educational materials from Astrogear.org. And finally, 3. Start thinking about planning or attend an Intenational Observe the Moon Night event on October 8.


So… Get engaged in the moon.


This donation link is specifically to donate to buy materials for teachers:







*For reasons I’ll never understand, in conference center speak, ballrooms are the large rooms that can contain the most chairs. While there may very occasionally be an actually ball in said ballrooms, their primary function is numbing butts while brains get filled.

Universal Education

Universal Education:

Here in the USA (or I should say there, since I’m currently in France), education tends to be somewhat nationalistic. It has to be. Teachers are tied to state and federal learning standards and if students don’t learn what is specifically listed in those standards, and specifically tested along those standards, schools are considered to have failed. While the national standards were written with the best of intentions to create a more literate population, they have had a stifling effect on creative teachers and creative learning environments. People like me do what we can to get the “fun stuff” (I’m biased toward thinking Astronomy goes in that fun category) into kids outside of school and I think we’re creating some pretty good things. What is amazing to me though is what I’m seeing coming out of Europe & Africa. And what is more amazing is what happens when you combine all the best there is in and out of school from around the world into one afternoon of talks.


Currently I’m in Nantes, France attending the joint Division of Planetary Sciences meeting ( DPS is a part of the American Astronomical Society) and the European Planetary Science Conference. As part of this week-long science extravaganza, there was a session on educational programs that make a global impact. I talked about citizen science (1, 2), and otherwise got to sit back and hear about other projects, many of which are children of the International Year of Astronomy that were able to grow and continue to thrive.


Starry Sky of an Alien Lake by Wally Pacholka

From TWAN: Starry Sky of an Alien Lake by Wally Pacholka


The session started with Mike Simmons of Astronomers without Borders. While Mike and his network date back to before IYA, they really came into their own during IYA with the coordination of 100 Hours of Astronomy. During a few brief spring (North) or fall (South) days, his team succeeded in brining together the world’s population in one global star party. IYA taught all of us that trying to engage the entire planet in one 100-hour span is hard work, and some people are guaranteed to be busy, so in recent years the program has transformed into the Global Astronomy Month, which invites everyone to look up during April. Different weeks and weekends have different themes. Beyond this amazing project, Astronomers without Borders also maintains The World at Night (photo project) and is planning global events for this June’s Transit of Venus. Poor Mike did all he could to pack it all into his 10-minute time slot, but it was to no avail. He was chased off the podium 3-minutes over. Honestly, his programs needed 55 minutes to do them any justice at all.


From Mike it passed to Roger Ferlet and Hand on Universe – EU. This project takes many of the best online / digital astronomy ideas of the past 15 years and does them using real NASA data processed using an interface called SalsaJ. Imagine, instead of using a simulator like CLEA to study the motion of Jupiter’s moons or the pulsations of a star you just looked at Jupiter’s moons and an actual pulsating star. SalsaJ is now on my list of things to learn sooner rather than later, and I’m hoping that if any of you are classroom teachers using SalsaJ, you’ll leave a comment about how you like it.

I went third and then passed the stage off to Connie Walker of the Dark Skies Awareness initiative (They do regular 365 Days of Astronomy shows!). These are the folks that every year bring you Globe at Night, a global data gathering project to measure how light pollution is impacting our ability to see the stars (and galaxies, etc) in the sky above us. In the past, this has been a once a year event involving getting everyone around the globe to look at the equator riding constellation Orion. Students and members of the public turn in information on how many of his stars they could see compared to a series of images, and we get a global reading of the sky. The thing is, lots of weird things can effect light pollution. Snow for instance. If you have a lot of street lights politely pointed down onto grass in parks, that isn’t too horribly bad, but if those same lights point onto snow… Well, that’s a nice mirror of light reflected into the sky. This year, to look at variations, and to see who can participate when, they’re introducing 4 different Globe at Nights events: January 14-23, February 12-21, March 13-22, and April 11-20 (that’s 2012).


With a line up of special events defined for us, the podium (or lack of podium) was handed over to Rosa Doren, a woman who is a force of nature bent on improving teacher preparation on a global level. Working on a budget of sofa change and sidewalk dimes, she has shown us what it means to leverage existing resources. As head of the IYA’s Galileo Teacher Training Program (which is still going strong!), she has brought together a global collaboration of people who are doing teacher training and providing teachers astronomy certification (at a variety of levels) by engaging them in a collections of activities in different content areas. The thing that consistently impresses me about this project is it realizes that schools aren’t all the same in terms of resources, but the same concepts of wanting to engage people rather then lecture at people apply. Don’t have a computer? That’s ok – they have a plan. Have a telescope and the most modern of technologies? That’s fine too. The sets of possible things teachers can do is varied enough to recognize the vast diversity of classroom needs, allowing teachers to learn concepts through tasks matched to their resources. Are you a teacher? Want to get the leg up on your astronomy content in a way that is relevant to the classroom you have instead of the classroom you wish you had? Check out the global listing of teacher workshops on their website.

The final talk I listened to well was on a classroom project I know I’ve mentioned before: Universal Awareness (UNAWE). Lead by Pedro Russo (formerly lead by Carolina Odman who’s no doing different awesomeness), and presented by a nice younger fellow whose name I didn’t catch, this program is designed to get little kids to love and learn space science through story telling. On their resources page they have a myriad of activities (including signing activities and telescope activities!), artwork from stories telling sky-lore from many different cultures, and all the teacher resources you might want (as a non-teacher, I like to download and print the art). Editions are available in multiple languages. The story that I heard (not told today, sadly) that most made me love this project was actually a story on it’s cultural impact. Through one set of activities, they get the kids telling their stories to a visiting outer space alien (a doll sewn by one of the community parents), and the alien in turn tells the kids stories about space through this curriculum. One teacher reported that after doing UNAWE in her class, an transfer student from a foreign country was seen as an interesting new thing – a source of potential stories and friendship. This was in contrast to how her kids normally treated transfer kids, as well, aliens in the not so warm and fuzzy story telling sense.


So the reason I said “listen well” is today I also learned I’m not really all that compatible with French food. I’m fine, but for a while, sitting a bit dehydrated (beverages are primarily expresso and wine here), and way overheated (no or limited AC and in the 80s), I just decided that rather than listening closely, I’d turn a color that caused a worried friend to ask if I was ok. After the session, I grabbed a couple cans of soda (failing to find hot tea, which I now have), and got to feeling better slowly but surely. I’m now fine, but during a few of the talks I wasn’t listening as much as I was doing a mental inventory of things like water bottles and tea bags I will hence forth always a) bring, and b) not leave on the plane (as I did with my water bottle on Saturday).


Unfortunately, this means the best I can do is offer you a link to the program for the rest of the session. No fear though, Thursday is another education session, and next week I’ll be at an astronomy communications meeting in Beijing (where I am compatible with the food). I’ll report what I hear. And tomorrow (room space willing) I’ll try and get you some science. So far, I fear to say, I’ve been thwarted by rooms with more people than space. Ah well, Emily Lakdawalla is early to arrive and easy to fit into small spaces and keeps managing to fit nicely into all the coolest sessions. Follow her on twitter and the Planetary Society Blog for all the best science this meeting has to offer.

Could There Be Life On Messier 13?

Could There Be Life On Messier 13?:






The Great Globular Star Cluster in Hercules



Messier 13 ( M13, NGC 6205) is a globular cluster of approximately 300,000 stars in the Hercules Constellation. It is also recalled as the Great Globular Cluster in Hercules or the Hercules Globular Cluster.


Having a magnitude of 5.8 and a diameter of about 23 arc minutes, Messier 13 can be easily seen with small telescopes and even with the naked eye when the sky is very clear. The brightest star of the globular cluster is the variable star V11, that has an apparent magnitude of 11.95. Close to Messier 13 is NGC 6207, a twice as big edge-on galaxy. Midway between them lies IC 4617, a small galaxy situated north-northeast of the globular cluster’s center.


In 1974 Messier 13 was the subject of a research. Scientists believed that due to a very high number of stars, the Hercules Globular Cluster could have an environment that sustains intelligent life forms. The Arecibo message was sent towards the globular cluster in order to establish communication with these hypothetical life forms. This experiment was meant to demonstrate more the evolution of technology than to establish communication with other life forms, because at the time of the message’s arrival M13 would have changed it’s location. Could there be life on Messier 13? Still remains an open question.


Distance from Earth: ~ 25000 light years.

How Common are Terrestrial, Habitable Planets Around Sun-Like Stars?

How Common are Terrestrial, Habitable Planets Around Sun-Like Stars?:


Artist concept of the Kepler telescope in orbit. Image Credit: NASA


Once again news from the Kepler mission is making the rounds, this time with a research paper outlining a theory that Earth-like planets may be more common around class F, G and K stars than originally expected.

In the standard stellar classification scheme, these type of stars are similar or somewhat similar to our own Sun (which is a Class G star); Class F stars are hotter and brighter and Class K stars are cooler and dimmer. Given this range of stars, the habitable zones vary with different stars. Some habitable planets could orbit their host star at twice the distance Earth orbits our Sun or in the case of a dim star, less than Mercury’s orbit.

How does this recent research show that small, rocky, worlds may be more common that originally thought?

A new look at the Fried Egg Nebula has revealed one of the rarest classes of stars in the Universe, a yellow hypergiant. This “sunny-side-up” view shows for the first time a huge dusty double shell surrounding this huge star.

“This object was known to glow brightly in the infrared but, surprisingly, nobody had identified it as a yellow hypergiant before,” said Eric Lagadec from the European Southern Observatory, who led the team that produced the new images.

And there’s good reason to keep an eye on this star: it will likely soon die an explosive death, and will be one of the next supernova explosions in our galaxy.

Have you seen a very bright star rising in the East every night the past few months? If you’re a night owl, you may have noticed it moves across they sky from the East into the West, shining brightly throughout the night. However this object is not a star! It’s the planet Jupiter and it is the brightest object in the night sky at the moment, apart from the Moon.

At the end of October Jupiter will be at opposition. This means the mighty planet (the largest in our solar system) will be directly opposite the sun as seen from Earth and it will also be at its closest point to Earth in the two planets’ orbits around the Sun. This makes Jupiter or any other object at opposition appear brighter and larger. The opposition of Jupiter occurs on October 29, 2011.

There’s a new telescope in town that just opened up for business. It’s the long awaited ALMA, the Atacama Large Millimeter/submillimeter Array. Although it is still under construction, the science teams have released the first “early science” image, showing a pair of interacting galaxies called the Antenna Galaxies. ALMA’s view reveals a part of the Universe that just can’t be seen by visible-light and infrared telescopes. “From the formation of the first galaxies, stars, and planets to the merging of the first complex molecules, the science of ALMA is a vast spectrum of investigation,” said Tania Burchell, the ALMA Public Information Officer at the National Radio Astronomy Observatory, on today’s 365 Days of Astronomy podcast.

“I used the astrometry.net software to solve each of the 100 photos, then the Swarp program to reproject and co-add the 100 red images, 100 green images, and 100 blue images in “SUM” mode.

The resulting three 32-bit FITS files (one per channel) were converted to a single 16-bit RGB TIFF file using ImageMagick convert, and then loaded into qtpfsgui to tone map as an HDR, using the Mantiuk algorithm with contrast 0.01, saturation 1.5, detail 4.0, and gamma 0.8. Some minor post-processing with The Gimp.”

Red Alert! Space Station Aurora

Red Alert! Space Station Aurora:


Astronauts had this view of the aurora on September 26, 2011. Credit: NASA


We’ve had some great views of the aurora submitted by readers this week, but this one taken from the International Space Station especially highlights the red color seen by many Earth-bound skywatchers, too. Karen Fox from the Goddard Space Flight Center says the colors of the aurora depend on which atoms are being excited by the solar storm. In most cases, the light comes when a charged particle sweeps in from the solar wind and collides with an oxygen atom in Earth’s atmosphere. This produces a green photon, so most aurora appear green. However, lower-energy oxygen collisions as well as collisions with nitrogen atoms can produce red photons — so sometimes aurora also show a red band as seen here.

Bending The Rules – Exploring Gravitational Redshift:


Researchers have analyzed measurements of the light from galaxies in approximately 8,000 galaxy clusters. Galaxy clusters are accumulations of thousands of galaxies (every light in the image is a galaxy), which are held together by their own gravity. This gravity affects the light that is sent out into space from the galaxies. Credit: Hubble Space Telescope


Hey. We’re all aware of Einstein’s theories and how gravity affects light. We know it was proved during a total solar eclipse, but what we’ve never realized in observational astronomy is that light just might get bent by other gravitational influences. If it can happen from something as small as a star, then what might occur if you had a huge group of stars? Like a galaxy… Or a group of galaxies! (...)

A Takahashi EM-200 mount I rented time on from SPACE (spaceobs.com) provided the tracking. This is a stack of three 1.5-min and three 2-min exposures. Processed with Lightroom and Photoshop.”

The Galactic Center is the rotational center of the Milky Way galaxy located 26,000 light years from the Earth. It was confirmed recently by the researchers at the Max Planck Institute for Extraterrestrial Physics in Germany that there exists a supermassive black hole at the galactic center. The observation was made using the 3.5m New Technology Telescope and the 8.2m Very Large Telescope (VLT) in Chile.

China launched their first space station module into orbit today (Sept. 29), marking a major milestone in the rapidly expanding Chinese space program. The historic liftoff of the man rated Tiangong 1 (Heavenly Palace 1) space lab on a Long March 2F rocket took place at 9:16 p.m. local time (9:16 a.m. EDT) from the Jiuquan Satellite Launch Center located in Gansu province in northwest China and is an impressive advance for China.

The beautiful nighttime liftoff occurred exactly on time and was carried live on China’s state run television – CCTV – and on the internet for all to see. Chinese President Hu Jintao and many of China’s other top government leaders witnessed the launch from the Beijing Aerospace Control Center as a gesture of confidence and support. Their presence was a clear sign of just how important China’s top leadership considers investments in research as a major driver of technological innovation (...)

According to data from the The Fast Imaging Plasma Spectrometer (FIPS) onboard NASA’s MESSENGER spacecraft, the solar wind is “sandblasting” the surface of Mercury at its polar regions.

Based on findings from one of seven different papers from the MESSENGER mission to be published in the Sept. 30th edition of Science, sodium and oxygen particles are charged in a manner similar to Earth’s own Aurora Borealis.

How are the University of Michigan researchers able to detect and study this phenomenon?

Jason Ahrns captured this incredible shot of the Aurora on April 9, 2011 in Alaska.

“The light on the trees is just the light out the windows of my cabin. The auroral arc was pretty much directly overhead so I was looking up into it, where you can see more structure than when you’re looking from the side.”

Jason used a Nikon D5000 and a Sigma 10-20mm f4/5.6 lens at 10mm. The exposure was 30 seconds at f4 and ISO 800.

Rick Ellis of Toronto, Canada came up with this multiple-exposure image of Venus setting. The changing position of Venus from the observer’s point of view serves as a proof of the the Earth’s counter-clockwise rotation.

This image was generated from multiple shots captured by Rick using his Canon A460 camera.

“It was not created on a single frame. The camera was locked down on its tripod and the original background photo was taken with Venus in the upper left. Then at exactly 5 minute intervals exposures were taken at ISO 80 for 5 seconds. Twenty seven exposures were made in all and then compiled in Photoshop. The trick then was to

find where Venus was on each successive layer and “punch a hole” very accurately in the main image layer.”

After Niki Giada’s photo of the Sun’s halo, here we are again with another impressive astrophoto. This time, it’s the Moon’s halo.

Earl Matenga captured this photo of the Moon and its halo on March 25, 2010 using a Pentax K-7.

Moon halos are brought about by the same phenomenon as Sun halos are. It’s caused by the refraction of light from tiny hexagonal ice crystals in the atmosphere.

This photo was shot through a Pentax fish eye lens mounted on tripod, bulb setting 2-3 sec exposure remotely fired. The red star on the left is Betelgeuse which is located in the constellation of Orion.

It’s one of the challenging subjects for astrophotography. But Don Scott of Arizona was able to obtain this amazing picture of The Hidden Galaxy, also known as IC 342.

IC 342 is an intermediate spiral galaxy in the constellation Camelopardalis. Since it’s also located near the Galactic Equator, IC 342 is mostly covered by dust from the Milky Way. With that, it has been nicknamed the “Hidden Galaxy.”

“I obtained this image last winter (Dec & Jan) here in Arizona using my telescope (Takahashi 130) and CCD camera (SBIG ST-10XME). It was a time exposure: Luminosity 3 hours, Red, Green, and Blue components 1 hour each. So this photo required 6 hours of exposure time. The scope focal length is 1000 mm, objective lens diameter is 130 mm, for a focal ratio of f/7.69. All of the foreground stars are approximately 10th magnitude.”

Erika Valdueza of the Philippines captured this photo of the partial lunar eclipse on December 21, 2010. The eclipse occurred at moonrise and appeared above the Sierra Madre Mountain Range in the northeastern part of Luzon island, Philippines.


“I wasn’t really expecting to see this eclipse because of poor weather and it was predicted to be visible 5 degrees above the horizon. Without losing hope, I tried my luck and went to one of the highest buildings in Mandaluyong City that has a good view of the east.”


The image was taken using Canon EOS Digital Rebel XSi camera with Canon EFS 55-250mm telephoto lens at f/6.3, ISO 400, 1/10 sec.
