A group of physicists at the Hong Kong University of Science and Technology found out that a single photon cannot travel faster than the speed of light in vacuum. The study reaffirms Einstein's theory that nothing travels faster than light, and most sadly, proves the impossibility of achieving the humanity's dream of time travel.

The largest body of water to date -- anywhere in the universe -- has been discovered in space, with mass measuring several trillion times the water on the whole of planet Earth.

Researchers have found the largest body of water anywhere in the universe, to date, with mass that measures several trillion times the mass of water on the entire planet Earth.

The future of NASA is all about deep space exploration now.

NASA has chosen a landing site for its next Mars rover with the goal of seeking more signs of life and historical water on the planet. Scientists have long known that Mars is home to a few patches of carbonates -- minerals that form readily in large bodies of water -- but they suspect that many more carbonates may be hidden beneath layers of the Red planet.

Astronomers have found a massive water vapor cloud floating around a black hole in the universe.

Officials at the Alaska Volcano Observatory warn that a remote Alaskan volcano may be poised for its next big eruption. The 5,676-foot Cleveland Volcano lies directly under commercial airline flight paths between North America and Asia.

Curiosity is planned to launch later this year and land in August 2012.

Astromomers found the largest reservoir of water ever discovered in space, which measures 140 trillion times the earth's ocean water. It is also the farthest reservoir of water discovered in the universe, according to two teams of researchers.

Mars Rover Curiosity will launch from earth in late 2011. By August 2012, it’s expected to land on Mars. Then, it’s expected to conduct a 2-year study of the red planet.

The Kepler Mission is a NASA Discovery Program for detecting potentially life-supporting planets around other stars.

After the landing of Space Shuttle Atlantis, NASA is bracing for its future in deep space exploration.

A huge reservoir of water engulfing a quasar, or a feeding black hole billions of light years away in outer confines of the universe, has been detected by scientists.

After careful deliberation, scientists have chosen the Gale crater as the landing site for the Mars rover Curiosity.

A new image released by NASA’s Spitzer Space Telescopes reveals a bright and swirling spider web in space evoked by a spiral galaxy’s starlight and a delicate pattern of dust in space.

NASA's Hubble Telescope has captured an unusual, ghostly green blob of gas that appears to float near a neighboring spiral galaxy.

Most of the huge black holes in the centers of galaxies in the past 11 billion years were not activated by galactic collisions, as had been previously thought, a new study reveals.

Astronomers have discovered a fourth moon orbiting the distant planet of Pluto using the Hubble Space Telescope. The latest discovery has been temporarily designated as P4 and joins the planet's other three satellites; Charon, Nix and Hydra.

NASA has picked the Gale crater to be the landing site of the Mars rover Curiosity.
