How to solve world hunger with pizza
The idea of a universal food synthesizer sounds like something straight out of the Jetsons or Star Trek, but thanks to a $125,000 grant from NASA, a 3-D food printer may become a reality.
Anjan Contractor, a senior mechanical engineer at Systems and Materials Research Corporation, is already working on bringing the idea to fruition.
NASA’s interested because storing the various ingredients as a power greatly extends their shelf life for lengthy travel through space, but Contractor wants to keep all of the recipes open source, so the general public could eventually benefit as well.
So how will the pizza be made?
Pizza will be one of the first items printed because of its natural layers of ingredients. First, a layer of dough will be printed and baked at the same time using a heated plate at the bottom of the printer. A layer of tomato base will follow — made of powder, water and oil — then a protein layer will top the pizza.

Brace yourself for another asteroid flyby
To quote science reporter Deborah Netburn:
It’s 1.7 miles long. Its surface is covered in a sticky black substance similar to the gunk at the bottom of a barbecue. If it impacted Earth it would probably result in global extinction. Good thing it is just making a flyby.
At approximately 1:59 p.m. PDT May 31, Asteroid 1998 QE2 will make a close (by galactic standards) pass by our home planet. Coming within just 3.6 million miles of Earth, the asteroid will be so close that many of its features will be visible on radar.

Solar flares galore!
Last night, the fourth major solar flare of the week burst onto the scene in a flash of ultraviolet radiation. And there may be even more just around the corner:
National Oceanic and Atmospheric Administration forecasters say there’s a good chance that more solar flares are on their way. The agency says there is a 50% chance of X-class solar flares and an 80% chance of less powerful M-class solar flares, in the next 24 hours.
You can read more on the flares over at Science Now, but for the time being, we’ll step back and let you look at the crazy photos above a bit longer.

Google presents global time-lapse views
Thanks to a new tool released by Google, NASA, the U.S. Geological Survey and Time magazine, the changes made to any location on Earth between 1984 and 2012 can be charted out.
As you can see above, the changes to Los Angeles aren’t all that drastic, but there are plenty crazy changes in other parts of the world:

This Year’s Largest Solar Flare
On April 11, 2013, at 3:16 a.m. EDT, the sun emitted an M6.5 flare, allowing NASA to capture this vibrant image. It’s not a particularly powerful solar flare, but it is the strongest of 2013 so far, and we’ll have plenty more opportunities to observe solar activity this year.
One of the craziest photos of the year.

Covering the Space Program
NASA doesn’t need much help selling the idea that space is super-awesome, but these covers for manuals and press conference notes from the golden age of spaceflight sure don’t hurt. They are going up for auction later this month. I wouldn’t mind having one or two of those hanging in my house, eh?
Meanwhile, in awesome space-related news.

via The Atlantic:
[Pictures of earth taken from space] are magical. They are mysterious. They are weird. They suggest, if they don’t fully embody, why we go to the trouble of exploring in the first place… And they often resemble art of a more earthly variety.
Play the game: NASA or MOMA?

It turns out the ancient universe is even more ancient
New findings from the European Space Agency’s Planck space telescope suggest that the universe is an estimated 13.8 billion years old, 100 million years older than previous thought.
Take a look at the picture above - that’s the radiation imprinted on the sky by the Big Bang itself, an observation from Planck that proved pivotal to the new age estimate.
From Science Now:
The map represents the first 15.5 months of observation by the Planck space telescope, which looked at the universe’s cosmic microwave background — that extremely cold, barely noticeable glow left after the Big Bang when the universe was just a cosmic baby — about 380,000 years old.
But don’t worry universe, you don’t look a day over 12 billion.

So…did Voyager 1 leave the solar system or not?
A report from the Geophysical Research Letters, a journal of the American Geophysical Union, claimed earlier today that the long-traveling Voyager 1 spacecraft had departed the solar system:
“It appears that V1 has exited the main solar modulation region, revealing Hydrogen and Helium spectra characteristic of those to be expected in the local interstellar medium.”
But NASA disagrees, according to a statement from Edward Stone, a Voyager project scientist based at Caltech:
“It is the consensus of the Voyager science team that Voyager 1 has not yet left the solar system or reached interstellar space.
In December 2012, the Voyager science team reported that Voyager 1 is within a new region called ‘the magnetic highway,’ where energetic particles changed dramatically. A change in the direction of the magnetic field is the last critical indicator of reaching interstellar space, and that change of direction has not yet been observed.”
Our money’s on the folks over at NASA. Read more on the debate over at Science Now.
Life on Mars…Maybe
A sample pulled from Mars just last month has been thoroughly examined by the Mars Science Laboratory Mission, and earlier today scientists declared that they have finally found solid evidence that Mars could have once sustained life.
From mission lead scientist John Grotzinger of Caltech:
“We have found a habitable environment that is so benign and is so supportive of life that probably if this water was around and you had been on the planet, you would have been able to drink it.”

Black hole spun: It’s been far too long since we shared some awesome space news. See that artist’s rendition above? That’s a black hole spinning near the speed of light. Even if it’s an interpretation, it’s still pretty darn incredible.
The image was sparked by the joint efforts of NASA’s X-ray telescope NuSTAR and the European Space Agency’s XMM-Newton space telescope, which examined the black hole anchoring NGC 1365 to determine how quickly it was spinning.
Just how does that work?
To solve the mystery, the XMM-Newton telescope — which studies low-energy X-rays, up to about 10 kiloelectron volts — teamed up with NuSTAR — which looks at very high-energy X-rays. NuSTAR, with a range from 3 to 79 kiloelectron volts, would fill in the rough sketch scientists had of this black hole.
