When Yale astrophysicist Kevin Schawinski and his colleagues at Oxford University enlisted public support in cataloguing galaxies, they never envisioned the strange object Hanny van Arkel found in archived images of the night sky.

This panorama mosaic, taken by the Surface Stereo Imager on board NASA's Phoenix Mars Lander, documents the passage of the midnight sun over several days.

Phoenix performed its first wet chemistry experiment on Martian soil flawlessly, returning a wealth of data from planet Mars that for Phoenix scientists was like winning the lottery.

Camera on Phoenix Arm Looks Beneath NASA Mars Lander. A view of the ground underneath NASA's Phoenix Mars Lander adds to evidence that descent thrusters dispersed overlying soil and exposed a harder substrate that may be ice.

NASA's Mars Reconnaissance Orbiter successfully received information from the Phoenix Mars Lander Tuesday evening and relayed the information to Earth. The relayed transmission included images and other data collected by Phoenix during the mission's second day after landing on Mars.

An Asteroid Deflection Research Center (ADRC) has been established on the Iowa State campus to bring researchers from around the world to develop asteroid deflection technologies. The center was signed into effect in April by the Office of the Executive Vice President and Provost.

Talk about a diet! By resolving, for the first time, features of an individual star in a neighbouring galaxy, ESO's VLT has allowed astronomers to determine that it weighs almost half of what was previously thought, thereby solving the mystery of its existence. The behemoth star is found to be surrounded by a massive and thick torus of gas and dust, and is most likely experiencing unstable, violent mass loss.

The historically less-than-50 per cent odds of success loomed heavily as NASA scientists readied for today's landing of the 420-million-dollar Phoenix spacecraft near the frigid north pole of Planet Mars.

Using new charge coupled device (CCD) instrumentation, Case Western Reserve University astronomers can now view the night sky wider and deeper than before.

Dr David Champion at CSIRO’s Australia Telescope National Facility and his colleagues from 20 other institutions publish their findings about the star today in the online journal, Science Express.

Astronomers have uncovered part of the missing matter in the universe, a discovery which they claim will help in understanding the evolution of the cosmic web in the future.

Today a very strange phenomena occurred in Florida Keys as a Ring around the sun was formed in the clear skies.
