Indian-origin scientist among those who discovered most distant galaxy ever

Astronomers have found the most distant galaxy ever, a discovery that pushes back scientists’ view of the universe to about 700 million years after it is thought to have come into existence.

Could life have survived a crash on Earth

Planetary scientists still consider the theory of panspermia, in which life can naturally transfer between planets, a serious hypothesis.

Hubble helps uncover 160,000 star clusters

NASA's Hubble Space Telescope has found the largest known population of globular star clusters, about 160,000, inside the core of the giant grouping of galaxies known as Abell 1689.

NASA receives ideas on how to deal with asteroids on collision course with Earth

NASA has been flooded with more than 400 suggestions on how to find asteroids that are on a collision course with Earth. Some suggestions were there to help relocate a small asteroid orbiting a moon for future study.

Brown dwarf `capable of giving birth to planet`

Brown dwarfs believed to be ‘failed stars,’ by researchers, could have the ability to give birth to planets. Brown dwarfs are believed to be built in a way similar to creation of stars.

Planets' overheating into boiling Venuses seems easier than believed

Astronomers have claimed that it may be easier for a planet to overheat into searing uninhabitable ‘runaway greenhouse’ stage than previously believed.

'Comet of the century' might fizzle out before reaching Sun’s orbit

The comet C/2012 S1 ISON, described by some as “the comet of the century,” has fizzled completely, and it is probable that it may disintegrate at or before reaching perihelion, according to new findings.

NASA to launch 'controversial' Asteroid Redirect Mission

NASA is on a lookout for a asteroid in space, which is circling the Sun and is passing close to Earth. The US space agency has proposed that the rock should neither be too big nor too small and should be about 7-10 metres in diameter.

How marine life adapts to acidification of oceans

A study into marine life around an underwater volcanic vent in the Mediterranean, may hold the key to understanding how some species will be able to survive the acidifying of sea water should anthropogenic climate change continue.

Hydrogen fuel harnessed directly from sunlight?

Gary Moore, a chemist with Berkeley Lab’s Physical Biosciences Division, said that they’ve developed a method by which molecular hydrogen-producing catalysts can be interfaced with a semiconductor that absorbs visible light.

Gas cloud being `stretched like spaghetti` as it swings past black hole

Recent observations of the galactic center have revealed that parts of the in-falling gas cloud, which was detected in 2011, have already swung past the black hole at the heart of our Milky Way.

Mars mission not for pride, we mean business: ISRO

Mystery behind Earth’s core still unresolved

A new study suggests that the differences between the east and west hemispheres of the Earth’s core are explained by the way iron atoms pack together.

NASA’s game changing composite cryogenic fuel tank tested
