Doomed Mercury-Sized Exoplanet May Be Turning to Dust

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.

Launch Day Timeline for SpaceX’s Dragon

Saturday morning’s launch window for SpaceX’s historic test flight to the International Space Station lasts just one second. Company President Gwynne Shotwell predicted they have “better than a 50-50 shot on whether we lift off tomorrow,” she said at a press conference today, adding, “If we lift off, we’ll get to orbit.”

Shotwell and NASA officials outlined a myriad of systems and activities that have to go perfectly for the launch take place, and then it will be non-stop action for the duration of the flight to orbit and ultimately the berthing of Dragon to the ISS.

Launch is set for 08:55 UTC on May 19 (4:55 AM Eastern/1:15 AM Pacific.) Here’s a timeline of activities so you can follow along while you watch the launch:

What Will Happen During Tomorrow’s SpaceX Launch:

Universe Today - Fri, 18/05/2012 - 20:00

With less than a day left before SpaceX’s historic launch of the first commercial vehicle to the ISS, slated for 4:55 am EDT on Saturday, May 19, here’s a video of what will happen once the Falcon lifts off.

(Part of me really wishes that they’ll be pumping out some dramatic music when it launches!)

The Awesome Complexity of Hypersonic Flight

Universe Today - Fri, 18/05/2012 - 19:04


Researchers at Stanford University are working on solutions to the inherent difficulties of hypersonic flight — speeds of over Mach 5, or 3,000 mph (4828 km/h) — and they’ve created one amazing computer model illustrating the dynamics of air temperature variations created at those intense speeds.

Watch Jupiter as a ‘Space Invader’

Universe Today - Fri, 18/05/2012 - 17:03

This great video created from images taken by the Solar and Heliospheric Observatory (SOHO) on May 13 and 14 show Jupiter as it comes close to the Sun (from our vantage point) in a solar conjunction. But what it really looks like is the old “Space Invaders” video game, with Jupiter marching across the screen. There’s even a couple of sungrazing comets “pewpew-ing” in like the laser cannon shots in the game, and a coronal mass ejection completes the scene as an explosion (which is actually more like “Asteroids.”) For more fun, the team who created this video at the Naval Research Laboratory’s Sungrazing Comets website takes the time to show all the different objects in the scene, which amazingly includes Callisto and Ganymede, two of Jupiter’s moons. All it needs is the funky video game background music.

Can You Find a Hubble Hidden Treasure?

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?
