UFO FLYING SAUCER Poll: Obama Better Than Romney at Defending Earth from Alien Attack

UFO FLYING SAUCER Poll: Obama Better Than Romney at Defending Earth from Alien Attack:

Not quite sure this is really relevant or at all scientific, but nearly two in three Americans think President Barack Obama would be better than Republican rival Mitt Romney in dealing with an alien invasion, according to a poll done by the National Geographic Channel. Surely, this is in response to the claim that Obama was teleported to Mars as a youth to meet and greet the Martians living there.
In addition, disappointingly, 36% of Americans believe UFOs exist, and 11% claim they have actually seen one, and 20% said they know someone who has seen one, the poll also determined.

Galactic Gong – Milky Way Struck and Still Ringing After 100 Million Years

Galactic Gong – Milky Way Struck and Still Ringing After 100 Million Years:
Small Magellanic Cloud
When galaxies collide, stars are thrown from orbits, spiral arms are stretched and twisted, and now scientists say galaxies ring like a bell long after the cosmic crash.
A team of astronomers from the United States and Canada say they have heard echoes of that ringing, possible evidence of a galactic encounter 100 million years ago when a small satellite galaxy or dark matter object passed through the Milky Way Galaxy; close to our position in the galaxy, as if a rock were thrown into a still pond causing the stars to bounce up and down on the waves. Their results were published in the Astrophysical Journal Letters.
“We have found evidence that our Milky Way had an encounter with a small galaxy or massive dark matter structure perhaps as recently as 100 million years ago,” said Larry Widrow, professor at Queen’s University in Canada. “We clearly observe unexpected differences in the Milky Way’s stellar distribution above and below the Galaxy’s midplane that have the appearance of a vertical wave — something that nobody has seen before.”

Oldest Impact Crater on Earth Discovered in Greenland

Oldest Impact Crater on Earth Discovered in Greenland:
Artistic expression of large meteorite impact
With shifting continents, rain, and wind, finding traces of ancient impact craters on Earth has been, literally, astronomically low. Now, an international team of scientists say they have found a massive impact crater in Greenland a billion years older than other known asteroid impact on Earth.
Scientists found the remains of the giant 100-kilometer (62 mile) wide crater near the Maniitsoq region of West Greenland and they believe it’s three billion years old. The largest and previously oldest known crater is the 300 kilometer-wide Vredefort crater in South Africa. Tipped on its side, the edges of the Maniitsoq crater would extend from the surface of the Earth to the edge of space.

Smoking Wildfires Seen From Space

Smoking Wildfires Seen From Space:

Wildfires continue to rage across the western United States, burning forests and property alike, and even the most remote have sent up enormous plumes of smoke that are plainly visible to astronauts aboard the Space Station.
The photo above was taken by an Expedition 31 crew member on June 27, showing thick smoke drifting northeast from the Fontenelle fire currently burning in Wyoming. More plumes can be seen to the north.

Pulsar Sets New Speed Record

Pulsar Sets New Speed Record:

A pulsar may have been spotted racing through space at over 6 million miles per hour (9.65 million km/h), setting a new speed record for these curious cosmic objects. If observations are what they appear to be, astronomers will have to recalculate the incredible forces created by supernova explosions.

Can You Find a Hubble Hidden Treasure?

Can You Find a Hubble Hidden Treasure?:

Visible in the constellation of Andromeda, NGC 891 is located approximately 30 million light-years away from Earth. Credit: ESA/Hubble & NASA
Just look at the kind of stunning images that are buried in the archives from the Hubble Space Telescope! Here, Hubble turned its powerful wide field Advanced Camera for Surveys towards this spiral galaxy and took this close-up of its northern half. The entire galaxy, called NGC 891, stretches across 100,000 light-years and we see it exactly edge-on. Visible are filaments of dust and gas escaping the plane of the galaxy. A few foreground stars from the Milky Way shine brightly in the image, while distant elliptical galaxies can be seen in the lower right of the image.
This is just an example of the hidden gems in Hubble’s archives that have never been seen by the general public. There’s a new contest to find more — so how can you participate?

Doomed Mercury-Sized Exoplanet May Be Turning to Dust

Doomed Mercury-Sized Exoplanet May Be Turning to Dust:

Artist concept of the curious events going at the star named KIC 12557548. Credit: MIT
The old saying of the universe being stranger than we can imagine definitely applies to a newfound exoplanet orbiting a star about 1,500 light years from Earth. Researchers using the Kepler space observatory have detected what appears to be a planet about the size of Mercury literally turning to dust. A long tail of debris — almost like a comet’s tail — is following the planet as it whirls around the star, KIC 12557548. Scientists think the planet could be evaporating under the blistering heat of the star, and that by analyzing the dust, they could decipher the history of the planet. But they better hurry. According to the team’s calculations, the planet will completely disintegrate within 100 million years.
“This might be another way in which planets are eventually doomed,” said Dan Fabrycky, a member of the Kepler Observatory science team.

Named after the Roman goddess of love and beauty, Venus has never looked more gorgeous! Prolific and accomplished astrophotographer John Chumack captured this shot of a crescent Venus on May 14, 2012 as it moves in for a transit of the Sun. Just 14% of Venus’ face was illuminated, 22 Days before the June 5th Transit of Venus across the Sun. John used a DMK 21AF04 fire-wire Camera, 2x Barlow, & 10″ SCT telescope, and used 950 frames stacked to create this image. Thanks to John for sharing his image; see more of his work at his website, Galactic Images.

Here’s a few unique vantage points of seeing the annular solar eclipse on May 20/21 2012. Above, one of the geostationary satellites called MTSAT (Multi-Functional Transport Satellite) built by Japan was able to capture the shadow over Earth near the maximum of the eclipse of May 20-21, 2012. It’s rather amazing how small the shadow is! “This image was generated during a color test of our Visible Daily-Earth project,” wrote Abel Mendez Torres on the PHL@UPR Arecibo website “and was taken by the MTSAT on May 21, 2012 @ 000 UTC (May 20, 2012 @ 8:00 PM EDT). Color correction was based on NASA Visible Earth datasets.” The Planetary Habitability Laboratory (PHL) is a research and educational virtual laboratory that studies of the habitability of Earth, the Solar System, and extrasolar planets, and @ProfAbelMendez is a very interesting person to follow on Twitter.
Below are a couple of videos: even though you are not supposed to look directly at the Sun during an eclipse, the PROBA-2 satellite did with an awesome result, and astronaut Don Pettit’s exceptional view of the eclipse from the International Space Station, as well as a view from the Hinode and Terra satellites:

A Planetary System That Never Was Teaches About Those That May Be

A Planetary System That Never Was Teaches About Those That May Be:

While Kepler and similar missions are turning up planets by the fist full, there’s long been many places that astronomers haven’t expected to find planetary systems. The main places include regions where gravitational forces conspire to make the region around potential host stars too unstable to form into planets. And there’s no place in the galaxy with a larger gravitational force than the galactic center where a black hole four and a half million times more massive than the Sun, lurks. But a new study shows evidence that a disk, potentially far enough along to begin forming planets, is in the process of being disrupted.

A ghost is haunting the Milky Way’s central black hole, revealing the galactic nucleus was likely much more active in the past than it is now. Scientists using the Fermi space telescope have found faint apparitions of what must have been powerful gamma-ray jets emanating from our galaxy’s center.
“These faint jets are a ghost or after-image of what existed a million years ago,” said Meng Su, an astronomer at the Harvard-Smithsonian Center for Astrophysics (CfA), and lead author of a new paper in the Astrophysical Journal. “They strengthen the case for an active galactic nucleus in the Milky Way’s relatively recent past.”

For over 50 years, award-winning space and astronomy artist David A. Hardy has taken us to places we could only dream of visiting. His career started before the first planetary probes blasted off from Earth to travel to destinations in our solar system and before space telescopes viewed distant places in our Universe. It is striking to view his early work and to see how accurately he depicted distant vistas and landscapes, and surely, his paintings of orbiting space stations and bases on the Moon and Mars have inspired generations of hopeful space travelers.

The Moon Affects the Solar Wind

The Moon Affects the Solar Wind:

his is a view of the moon transiting, or passing in front of, the Sun as seen from the STEREO-B spacecraft on Feb. 25, 2007. The Sun is in false color, and the moon appears as a black disk on the upper right. NASA's STEREO mission consists of two spacecraft launched in October, 2006 to study solar storms. Credit: NASA
From a NASA press release:
With the Moon as the most prominent object in the night sky and a major source of an invisible pull that creates ocean tides, many ancient cultures thought it could also affect our health or state of mind – the word “lunacy” has its origin in this belief. Now, a powerful combination of spacecraft and computer simulations is revealing that the moon does indeed have a far-reaching, invisible influence – not on us, but on the Sun, or more specifically, the solar wind.

Worlds Without Suns: Nomad Planets Could Number In The Quadrillions

Worlds Without Suns: Nomad Planets Could Number In The Quadrillions:

Artist's concept of a free-floating Jupiter-like planet. (NASA / JPL-Caltech)
The concept of nomad planets has been featured before here on Universe Today, and for good reason. Not only is the idea of mysterious lone planets drifting sunless through interstellar space an intriguing one, but also the sheer potential quantity of such worlds is simply staggering. If some very well-respected scientists’ calculations are correct there are more nomad planets in our Milky Way galaxy than there are stars — a lot more. With estimates up to 100,000 nomad planets for every star in the galaxy, there could be literally quadrillions of wandering worlds out there, ranging in size from Pluto-sized to even larger than Jupiter.
That’s a lot of nomads. But where did they all come from?

It’s Inevitable: Milky Way, Andromeda Galaxy Heading for Collision

It’s Inevitable: Milky Way, Andromeda Galaxy Heading for Collision:

This illustration shows a stage in the predicted merger between our Milky Way galaxy and the neighboring Andromeda galaxy, as it will unfold over the next several billion years. In this image, representing Earth's night sky in 3.75 billion years, Andromeda (left) fills the field of view and begins to distort the Milky Way with tidal pull. (Credit: NASA; ESA; Z. Levay and R. van der Marel, STScI; T. Hallas; and A. Mellinger)
Astronomers have known for years that our Milky Way and its closest neighbor, the Andromeda galaxy, (a.k.a M31) are being pulled together in a gravitational dance, but no one was sure whether the galaxies would collide head-on or glide past one another. Precise measurements from the Hubble Space Telescope have now confirmed that the two galaxies are indeed on a collision course, headed straight for a colossal cosmic collision.

A Rare Type of Solar Storm Spotted by Satellite

A Rare Type of Solar Storm Spotted by Satellite:

Artist's impression of solar cosmic rays striking Earth's atmosphere (Simon Swordy/University of Chicago, NASA)
When a moderate-sized M-class flare erupted from the Sun on May 17, it sent out a barrage of high-energy solar particles that belied its initial intensity. These particles traveled at nearly the speed of light, crossing the 93 million miles between the Sun and Earth in a mere 20 minutes and impacting our atmosphere, causing cascades of neutrons to reach the ground — a rare event known as a ground level enhancement, or GLE.
The first such event since 2006, the GLE was recorded by a joint Russian/Italian spacecraft called PAMELA and is an indicator that the peak of solar maximum is on the way.

A composite image of galaxy CID-4 shows evidence the black hole is being ejected. Credit: X-ray: NASA/CXC/SAO/F.Civano et al; Optical: NASA/STScI; Optical (wide field): CFHT, NASA/STScI
Talk about a tough neighborhood! Even black holes aren’t welcome in galaxy CID-42, located about 4 billion light-years away from Earth. Astronomers using the Chandra X-Ray Observatory have found strong evidence that a massive black hole is being ejected from this galaxy, moving out at a speed of several million kilometers per hour. This phenomenon, known as a recoiled black hole, happens due to a gravitational wave “kick” from the merger of two black holes.
While this event is likely to be rare, it could mean that there could be giant black holes roaming undetected out in the vast spaces between galaxies.

Astrophotographer Thierry Legault had told us he was traveling to Australia for the Transit of Venus, so we knew he had something special planned. But that still didn’t prepare us for the awesomeness of what he has just achieved. During the Transit of Venus, Legault also captured the Hubble Space Telescope moving across the face of the Sun. Not once, but 9 times, during the HST’s transit time of .97 seconds. “Thanks to the continuous shooting mode of the Nikon D4 DSLR running at 10 fps,” Legault said on his website, which shows his new images. Of course, due to the differences in distance from Earth of Hubble vs. Venus, Venus took a lazy 6-plus hours to make its transit. A few giant sunspots also join in the view.
Below see a close-up of the two transits and a look at Legault’s set-up in the Outback of Queensland.

Timelapse: Shuttle Enterprise Removed from 747 Aircraft

Timelapse: Shuttle Enterprise Removed from 747 Aircraft:

Yesterday, space shuttle Enterprise was removed from NASA’s 747 Shuttle Carrier Aircraft at JKF Airport in New York. You can watch an entire night’s activities in a little over a minute, and even watch the Moon rise over the action. Enterprise will be placed on a barge that will bring Enterprise via tugboat up the Hudson River to the Intrepid Sea, Air & Space Museum. This will happen in June, and then the shuttle will be lifted by crane and placed on the flight deck of the Intrepid, where it will be on exhibit to the public starting this summer in a temporary climate-controlled pavilion. The museum is still working on their permanent display home for Enterprise.

PHOTO : A Planetary Ring and 64 Moons Around Planet Jupiter

A Planetary Ring and 64 Moons Around Planet Jupiter:

PHOTO : A Planetary Ring and 64 Moons Around Planet Jupiter
PHOTO : A Planetary Ring and 64 Moons Around Planet Jupiter
Biggest Planet and Biggest Moon in the Solar System
Jupiter is the fifth planet from the Sun and the biggest planet of the Solar System, its mass being more than twice as big as all the other planets combined.  Along with Saturn, Uranus and Neptune, the four giant planets are known as the Jovial.
Planet Jupiter has mostly in its component hydrogen and helium, but it might also have a rocky core of heavy elements. Due to the high speed of its rotation, Jupiter has the shape of an oblate spheroid, having both poles closer to the core than the equator. The outer atmosphere of Jupiter is divided into separated latitude layers, which cause turbulence and storms when they interact. The most significant result of  the layers interaction is a giant storm still in process, discovered in the 17th century . This storm is known by the name of the Great Red Spot.
Jupiter is surrounded by a slightly detectable planetary ring and a strong magnetosphere. What makes this planet interesting is not only its size, but also the fact that Jupiter has 64 moons. Four of the moons are very famous: Io, Europa, Ganymede and Callisto, also called the Galilean moons, after their discoverer Galileo Galilei. Ganymede is the biggest natural satellite in the Solar System, being bigger than the planet Mercury.
Along with the Sun, the Moon and planet Venus, Jupiter is the fourth largest object seen by the naked eye. The gravitational influence of planet Jupiter played a very important role in the shaping process of the solar System. Thereby, the majority of the planets orbit closer to Jupiter’s orbital plane than to the Sun’s equatorial plane.  Mercury is the only planet that makes an exception, being closer to the Sun. Also, it’s high gravitational level might have caused the Kirkwood gaps in the asteroid belt and the  Late Heavy Bombardment of the inner Solar System’s history.
Distance from Earth: 0.0000621 light years, about 32 light minutes

Humans Respond to First Contact from an Alien World

How Would Humans Respond to First Contact from an Alien World?:

Artist concept of an exoplanet. Credit: NASA
According to Star Trek lore, it is only 51 years until humans encounter their first contact with an alien species. In the movie “Star Trek: First Contact,” on April 5, 2063, Vulcans pay a visit to an Earth recovering from a war-torn period (see the movie clip below.) But will such a planet-wide, history-changing event ever really take place? If you are logical, like Spock and his Vulcan species, science points towards the inevitability of first contact. This is according to journalist Marc Kaufman, who is a science writer for the Washington Post and author of the book “First Contact: Scientific Breakthroughs in the Hunt for life Beyond Earth.” He writes that from humanity’s point of view, first contact would be a “harbinger of a new frontier in a dramatically changed cosmos.”
What are some of the arguments for and against the likelihood of first contact ever taking place and what would the implications be?
