By comparing infrared and X-ray background signals across the same stretch of sky, an international team of astronomers has discovered evidence of a significant number of black holes that accompanied the first stars in the universe.
Traveling from one alien world to another, Dawn is reliably powering its way through the main asteroid belt with its ion propulsion system.
NASA comes out with some amazing images and now, the agency's Spitzer Space Telescope has come up with a few more. The new pictures reveal blooming stars in our Milky Way galaxy's more barren territories, far from its crowded core.
The Mars rover Curiosity may not have found evidence of life, but it's definitely found evidence of water on the Red Planet. NASA scientists have revealed that the rover has found evidence that rivers once ran across the surface of Mars that were between an inch to nearly three feet deep.
About 700 light-years away from Earth, a hot Saturn-like planet exists in another solar system. Now, astronomers have caught sight of the planet, and have learned a little bit more about it by using inexpensive ground-based telescopes.
The new discovery explains how the reactive 'phosphorous' an essential component for creating life form came to Earth from asteroids some 3.5 billion years ago and they helped in creating the earliest form of life.
NASA and a Texas company are exploring the possibility of using a "3D printer" on deep space missions in a way where the "D" would stand for dining.
New global maps of Mars released on the 10th anniversary of the launch of ESA’s Mars Express trace the history of water and volcanic activity on the Red Planet, and identify sites of special interest for the next generation of Mars explorers.
Novae can be explosive, spewing material into space as they erupt. Now, astronomers have used NASA's Hubble Space Telescope to observe the light emitted by the close double-star system T Pyxidis during its latest stellar outburst and create a 3D map.
NASA's Swift Satellite has captured some spectacular images. The instrument has helped create the most detailed ultraviolet light surveys ever of the Large and Small Magellanic Clouds, the two closest major galaxies.
Scientists have discovered some amazing things in our universe. Now, they've uncovered a bright dwarf galaxy relatively close to Earth's Milky Way in its death throes as it trails fireballs across the sky.
Astronomers once thought that our Solar System's Milky Way galaxy resided in a small structure called the Local Arm. Now, though, they've discovered that the Local Arm is far larger than previously thought and is more like the adjacent major arms rather than a small spur.
