Mars now appears to be a cold desert world and it has no global magnetic field. The cold temperatures and thin atmosphere on the red Planet do not allow liquid water to exist at the surface for long. But it might not have been always so.

NASA published the first edition of its software catalog in April 2014. Since then, NASA has shared thousands of its software programs with students, industry, individuals and other government agencies.

"These are the best Earth-sized planets for the James Webb Space Telescope to characterize, perhaps for its whole lifetime," Hannah Wakeford, postdoctoral fellow at NASA's Goddard Space Flight Center in Greenbelt, Maryland, said.

Observations with Hubble are helping astronomers to understand the mass of UGC 12591, and to determine whether the galaxy simply formed and grew slowly over time, or whether it might have grown unusually massive by colliding and merging with another large galaxy at some point in its past, NASA said.

NASA scientists have demonstrated that a new space weather warning system could help astronomers detect harmful solar particles much before they leave the sun's inner atmosphere -- critical extra time that could help protect astronauts in space.

The two individuals approached SpaceX for the trip and they have "already paid a significant deposit" to do a moon mission, the company said in a statement on Monday.

Days after the US President Donald Trump promised to "unlock the mysteries of space", NASA has kicked off a study to assess the feasibility of adding a two-member crew to the first unmanned flight of the agency's Space Launch System (SLS) rocket and Orion spacecraft called Exploration Mission-1 (EM-1).

NASA on Wednesday announced that life may have evolved on at least three planets in a newly discovered solar system. This system is just 39 light years from Earth and have no less than seven Earth-sized worlds orbiting a cool dwarf star known as TRAPPIST-1.

Sending an antibiotic-resistant superbug to a zero-gravity environment like the International Space Station (ISS) will help NASA better understand how superbugs mutate to become resistant to available antibiotics, an India-origin researcher has said.

Forget space shuttles and rockets, luxury car brand Bentley has now taken the help of NASA for purely promotional reasons.
