Wow, what a view of the Curiosity rover! This is a self-portrait mosaic made from brand new images taken by the MAHLI (Mars Hand Lens Imager), the high-resolution camera located on the turret at the end of MSL’s robotic arm. The arm was moved for each of the 55 images in this mosaic, so the arm doesn’t show up in the mosaic. This montage was put together by Stuart Atkinson, and he notes that these images are just the low-res thumbnail images that have just been sent to Earth. “Imagine what the hi-res version will look like!!” Stu said.

Using NASA's Fermi Gamma Ray Space Telescope, scientists were able to detect the light of the earliest stars, which are now long since gone... One of the primary goals of the Fermi Gamma Ray Space Telescope is to measure the starlight in the universe and use that to figure out how much light has ever shone in it. Yesterday, astronomers on Fermi’s research team announced that they have reached that goal.

Scientists have spent years hunting for Earth-like planets orbiting stars elsewhere in the galaxy. Now they have found one that's a relative stone's-throw away. The so-called exoplanet — a planet beyond our solar system — is circling Alpha Centauri B, just 4.37 light-years from Earth. A mere 3.7 million miles from the star's surface, it is far too hot to support life. But there's a chance that another planetary sibling may reside in the system's so-called habitable zone, where liquid water could exist, scientists say.

Ooh, shiny! NASA's Curiosity rover has spotted something curious on the Martian soil, likely "a shred of plastic" from the rover, says the space agency. Still, NASA is taking a hard look at the mystery object.

You know that scene in the film Contact where the “Machine” is spooling up, its three spinning rings kicking out crazy light and an electromagnetic field powerful enough to pitch nearby Navy battleships sideways, as Ellie (Jodie Foster) waits, terrified, in her tiny spherical craft above the space-time bedlam, to plummet into the vortex?

The NASA rover Curiosity has beamed back pictures of bedrock that suggest a fast-moving stream, possibly waist-deep, once flowed on Mars -- a find that the mission's chief scientist called exciting.

The eXtreme Deep Field (XDF) focuses on a small patch of the constellation Fornax, containing some 5,500 galaxies. The image was culled from 10 years of photos of the same region of space shown in the Hubble Ultra Deep Field, which was last updated in 2009, based on data gathered in 2003 and 2004.

No, it’s not science fiction: for those who have run out of places to go, companies are competing to take amateur astronauts into the heights, and beyond.

Getting a six-wheeled car-size rover safely onto the surface of the red planet? Daunting, sure. But NASA did it with Curiosity. Sending humans on a mission to Mars? That requires overcoming even more outlandish obstacles.

David's time on Earth had come to a temporary end — and he was taking his family with him. As soon as the rover Curiosity dropped onto the Martian surface on Aug. 5, David and hundreds of his fellow scientists and engineers at NASA's Jet Propulsion Laboratory switched from Earth time to Mars time.
