As George Clooney's character in Gravity said, "You can't beat the view"

NASA Expedition 38 crew members Mike Hopkins and Rick Mastracchio recorded this incredible footage of Earth from the Cupola - the massive observatory module of the ISS. 

As the planet rotates in view, the astronauts name countries, cities, and landmarks rocketing across the skyline.

NASA Unveils Incredible Star Trek-style Warp Drive Space Ship: PHOTOS

NASA

This week, NASA engineer Harold White and digital artist Mark Rademaker unveiled the IXS Enterprise - a years-in-the-making CGI design concept for a potential warp drive space ship of the future. Chris Pine and Zachary Quinto sadly not included. 

The Washington Post reports:

“We wanted to have a decent image of a theory conforming Warp ship to motivate young people to pursue a STEM career,” Rademaker said in an e-mail interview. “It does have some Sci-Fi features that might never transfer to a possible final design, unless we really want to.”

A warp ship such as the IXS Enterprise could allow travel to interstellar space in a matter of weeks rather than, say, centuries. And the science behind why it might be possible is truly mind-boggling.

An over-simplified explanation is that the concept seeks to exploit a “loophole” in Albert Einstein’s theory of relativity that allows travel faster than the speed of light by expanding space-time behind the object and contracting space-time front of it.

When asked the question on all our minds – “When can I get one of these?” White said that proving that the math behind the model is the first and most important step in the process. 

For now, we'll just have to make do with the awesome photos of the design, which you can check out AFTER THE JUMP...

Hubble Telescope Takes Most Colorful Photo Ever of The Evolving Universe

Hubble photograph

And it's full of stars; the picture above is just a segment of the whole thing. The photo, called the Hubble Ultra Deep Field 2014 image, is a composite of exposures taken by the Hubble Telescope from 2003 to 2012.

The scope of the photograph is simply gargantuan in scale. It captures over 10,000 galaxies, some of which are billions of light years away, extends back to within a few hundred millions of years of the big bang, and is presently regarded as "among the most colorful deep space images ever captured by the 24-year-old telescope."

Plus it makes for a great iPad parallax wallpaper.


SpaceX Unveils Reusable ISS 'Taxi' for 7 Astronauts: VIDEO

Musk

Elon Musk last night revealed the new SpaceX reusable craft for seven astronauts which he hopes will ferry them back and forth to the International Space Station one day.

Dragonv2Private companies are vying for contracts from NASA for the taxis, which will hopefully reduce our reliance on Russia's space program.

Watch, AFTER THE JUMP...

TechCrunch writes:

The reason that this is really import,” said Musk, “is that it allows rapid reusability of the spacecraft. You just refill the propellant, and go again… Imagine if aircrafts were thrown away after each flight; no one could afford to fly.””

2_dragonv2SpaceX had previously shown Dragon V1, a smaller, unmanned version of this craft meant primarily for testing and, in a few cases, sending cargo back and forth to the International Space Station. Dragon V2 also has an improved heat shield, allowing it to better protect passengers on their return flight through the atmosphere.

The biggest single change to the design, though, is in the engines: where each of Dragon V1′s engines (the “Draco” engine) could produce about 100 pounds of thrust, each of the Dragon V2′s engines (the aptly dubbed “Super Draco” engines) can produce about 16,000 pounds of thrust. The particularly cool part? SpaceX says they’re actually 3d printing the engines out of a specialized metal alloy (called inconel), as opposed to more traditional manufacturing methods like milling.

New 'Earthrise' Image from NASA: PHOTO

Earthrise

NASA's Lunar Reconnaissance Orbiter Camera released a stunning new shot of the Earthrise yesterday. In the photo, the Earth is a color composite very close to what a person would see from the same perspective, and the brightness contrast of the Earth and moon is also very accurate.

They write:

LRO experiences twelve earthrises every day, however LROC is almost always busy imaging the lunar surface so only rarely does an opportunity arise such that LROC can capture a view of the Earth. On the first of February of this year LRO pitched forward while approaching the north pole allowing the LROC WAC to capture the Earth rising above Rozhdestvenskiy crater (180-km diameter).

The LROC Wide Angle Camera (WAC) is very different than most digital cameras. Typically resolution is reported as the number pixels in a single image, a cell phone camera today has more than 5 million pixels (5 megapixels). A single WAC frame has only 9856 pixels, however the WAC builds up a much larger image by exposing a series of images (or frames) as LRO progresses in its orbit; this type of imaging is called "push-frame". Over a full month as the LRO orbit track progresses around the Moon the WAC builds up a collection of images that covers the entire globe.


NASA Explains Tonight’s ‘Blood Moon’ Lunar Eclipse: VIDEO

Screen Shot 2014-04-14 at 5.18.14 PM

To help prepare you for tonight’s ‘total lunar eclipse, the folks over at NASA have prepared a handy video to fill you in on the science behind the ‘blood moon.’

I think the eclipse probably something to do with vampires, but Texas pastor and televangelist John Hagee is claiming it’s a sign of the End Times. No word yet if he’s blaming it on the gays like he did with Hurricane Katrina though...

Check out the video, AFTER THE JUMP...

FYI: The eclipse begins around 12:53 am ET and will reach totality around 3am ET
