Is the Moon Mars Myth Over?

Is the Moon Mars Myth Over?:

Mars and the Moon -- NOT. Credit: Scientific American

Twitter users Kris McCall and Wayne Povey reminded me that it’s August 27th today. Don’t you know what that is? That’s the day all those stupid “Mars is going to look bigger than the Moon” hoax emails go around the internet. We’ll usually get deluged by emails from the recipients, and have to write up a big response explaining it… again… and again… and again.


But I just realized… I haven’t gotten a single email this year. I totally forgot to mention it in Universe Today.


So that’s it, I’m officially calling this hoax over. You hear me hoaxers and remailers? You’ve lost. People now understand that there’s no possible way that Mars can look bigger in the sky. Your ridiculous hoax is falling on deaf ears. It just took 8 years of non-stop debunking.


Skepticism has won this day.

Astronomy Without A Telescope – Why The LHC (Still) Won’t Destroy The Earth

Astronomy Without A Telescope – Why The LHC (Still) Won’t Destroy The Earth:

Concerns about a 'big science machine' destroying the Earth have been around since the steam engine. The LHC is the latest target for such conspiracy theories. Credit: CERN.

Surprisingly, rumors still persist in some corners of the Internet that the Large Hadron Collider (LHC) is going to destroy the Earth – even though nearly three years have passed since it was first turned on. This may be because it is yet to be ramped up to full power in 2014 – although it seems more likely that this is just a case of moving the goal posts, since the same doomsayers were initially adamant that the Earth would be destroyed the moment the LHC was switched on, in September 2008.


The story goes that the very high energy collisions engineered by the LHC could jam colliding particles together with such force that their mass would be compressed into a volume less than the Schwarzschild radius required for that mass. In other words, a microscopic black hole would form and then grow in size as it sucked in more matter, until it eventually consumed the Earth.


Here’s a brief run-through of why this can’t happen.(...)

In as much time as it takes to give birth to human life, a supercomputer and a team of researchers at the University of California, Santa Cruz, and the Institute for Theoretical Physics in Zurich have given rise to the first simulation of the physics involved in galaxy formation that produced the Milky Way.

Opportunity investigates Tisdale 2 rock showing indications of ancient Martian water flow

NASA's Mars Exploration Rover Opportunity used its front hazard-avoidance camera to take this picture showing the rover's arm extended toward a light-toned rock, "Tisdale 2," during Sol 2695 of the rover's work on Mars (Aug. 23, 2011). The composition of Tisdale 2 is unlike any rock studied by Opportunity since landing 7.5 years ago. It is about 12 inches (30 centimeters) tall. Credit: NASA/JPL-Caltech

Updated with more team comments and images

Opportunity has begun a whole new mission at the vast expanse of Endeavour Crater promising a boatload of new science discoveries.


Scientists directing NASA’s Mars Opportunity rover gushed with excitement as they announced that the aging robot has discovered a rock with a composition unlike anything previously explored on the Red Planet’s surface – since she landed on the exotic Martian plains 7.5 years ago – and which offers indications that liquid water might have percolated or flowed at this spot billions of years ago.


Barely three weeks ago Opportunity arrived at the rim of the gigantic 14 mile ( 22 km) wide crater named Endeavour after an epic multi-year trek, and for the team it’s literally been like a 2nd landing on Mars – and the equivalent of the birth of a whole new mission of exploration at an entirely ‘new’ landing site.

Where’s the Debris for Transiting Planets?

Where’s the Debris for Transiting Planets?:







For many exoplanet systems that have been discovered by the radial velocity method, astronomers have found excess emission in the infrared portion of the spectrum. This has generally been interpreted as remnants of a disk or collection of objects similar to our own Kupier belt, a ring of icy bodies beyond the orbit of Pluto. But as Kepler and other exoplanet finding missions rake in the candidates though transits of the parent star, astronomers began noticing something unusual: None of the exoplanet systems discovered through this method were known to have debris disks. Was this an odd selection effect, perhaps induced by the fact that transiting planets often orbit close to their parent stars, making them more likely to pass along the line of sight which could in turn, betray different formation scenarios? Or were astronomers simply not looking hard enough? A recent paper by astronomers at the Astrophysikalisches Institut in Germany attempts to answer that question.

Five Awesome Things You (Probably) Didn’t Know Asteroseismology Could Do

Five Awesome Things You (Probably) Didn’t Know Asteroseismology Could Do:

The variations in brightness can be interpreted as vibrations, or oscillations within the stars, using a technique called asteroseismology. The oscillations reveal information about the internal structure of the stars, in much the same way that seismologists use earthquakes to probe the Earth's interior. Credit: Kepler Astroseismology team.

Asteroseismology is a relatively new field in astronomy. This branch uses sound waves in stars to explore their nature in the same way seismologists on Earth have used waves induced by tectonic activity to probe the interior of our planet. These waves aren’t heard directly, but as they strike the surface they can cause it to undulate, shifting the spectral lines this way and that, or compress the outer layers causing them to brighten and fade which can be detected with photometry. By studying these variations, astronomers have begun peering into stars. This much is generally known, but some of the specific tricks aren’t often brought up when discussing the topic. So here’s five things you can do with asteroseismology you may not have known about!

No, NASA is Not Predicting We’ll be Destroyed by Aliens:

Movie poster from 'Aliens Attack," via getfilm.co.uk

There were some interesting, if not shocking headlines this week regarding a study supposedly put out by NASA, with the articles saying that aliens might come and destroy Earth because of our global warming problems. Headlines such as:


Aliens Could Attack Earth to End Global Warming, NASA Frets (Fox News)


Global Warming Could Provoke Alien Attack: NASA (International Business Times)


NASA: Aliens might destroy us because of our gases, (CNET)


and this one, which started the whole thing:


Aliens may destroy humanity to protect other civilizations, say scientists (The Guardian — The subheadline for this article originally said it was a NASA report, but has since been amended)


While the report is real, and one of the authors was a NASA intern, NASA in no way sponsored or endorsed the article, which was basically an enjoyable thought-experiment, and was titled: “Would Contact with Extraterrestrials Benefit or Harm Humanity? A Scenario Analysis.”

A beautiful and colorful halo — a 22 degree ring — as seen on the island of Lanzarote in the Canary Islands, taken by ‘Astrohans” on Flickr. Astrohans posted that circumhorizontal arc is also visible, and that the photo was taken on May 8, 2010 in Playa Blanca, using a Canon EOS 400D Digital.


Halos form when light from the Sun or Moon is refracted by ice crystals associated with thin, high-level clouds (like cirrostratus clouds). A 22 degree halo is a ring of light 22 degrees from the Sun (or Moon) and is the most common type of halo observed.

Who wouldn’t love to see this showcase of colors on a night sky? Definitely worth a click!




It was during a solar maximum in the mid-1990s when Tony Cellini took this nice photo of the Aurora Borelis in Bloomington, Illinois.

“This was one of most intense aurorae I’ve ever seen this far south and the image doesn’t beging to capture its extent. Even during a 1st quarter moon, the green tendrils were visible straight overhead, and the red coloring was very obvious to the naked eye which is unusual from this location.”

If you would like to know how he came up with this photo, Tony also mentioned the camera and settings he used.

“The camera used was a fully manual Pentax K-1000. The lens was a standard 50mm lens to which I threaded a fisheye “converter” that gave an almost 180 degree field of view. The cheap converter is what caused the concentric rings artifact in the center of the photo.”
