| Watery asteroid discovered in dying star points to habitable exoplanets Posted: 10 Oct 2013 11:27 AM PDT Latest research on rocky relics suggests a distant planetary system, now past its "death throes", had very similar water 'delivery system' to our own -- and consequently the potential to contain habitable exoplanets complete with water. |
| Water discovered in remnants of extrasolar rocky world orbiting white dwarf Posted: 10 Oct 2013 11:27 AM PDT Astrophysicists have found the first evidence of a water-rich rocky planetary body outside our solar system in its shattered remains orbiting a white dwarf. |
| Soft shells and strange star clusters Posted: 10 Oct 2013 06:16 AM PDT The beautiful, petal-like shells of galaxy PGC 6240 are captured here in intricate detail by the NASA/ESA Hubble Space Telescope, set against a sky full of distant background galaxies. This cosmic bloom is of great interest to astronomers due to both its uneven structure, and the unusual clusters of stars that orbit around it -- two strong indications of a galactic merger in the recent past. |
