[ Watch the Video: Laser Lights Criss Cross Hawaiian Skies ] April Flowers for redOrbit.com - Your Universe Online The annual Perseid Meteor Shower will peak this weekend. As redOrbit’s Lawrence Leblonde reported, scientists are predicting that due to a lack of strong moonlight, this could be one of the most impressive shows in years. But that isn’t the reason scientists are so happy about the shower. In addition to a fantastic light show every summer, the Perseid shower provides...

[ Watch the Video ] The European Southern Observatory (ESO) announced on Wednesday that astronomers have accurately measured the diameter of the dwarf planet Eris for the first time. The astronomers believe that the dwarf planet is an almost perfect twin of Pluto in terms of size.  The planet, according to ESO, appears to have a reflective surface, which suggests it is uniformly covered in a thin layer of ice. Astronomers made observations as Eris passed in front of a faint...

Astrobiology Magazine -- When planetary scientists announced on July 29 that they had discovered a new planet larger than Pluto, the news overshadowed the two other objects the group had also found. But all three objects are odd additions to the solar system, and as such could revolutionize our understanding of how our part of the celestial neighborhood evolved. To the discoverers, the objects still go by the unofficial code-names "Santa," "Easterbunny," and "Xena," though they are...

Gemini -- Recent spectroscopic studies of infrared light reflected from the surface of Sedna reveal that it is probably unlike Pluto and Charon since Sedna's surface does not display evidence for a large amount of either water or methane ice. Due to Sedna's extreme distance from the Sun, the frigid surface has probably been untouched for millions of years by anything except cosmic rays and solar ultraviolet radiation. Gemini Observatory astronomer Chad Trujillo led an effort by the same...

Quaoar -- Quaoar ("kwah-oh-ahr", /kwA o Ar/) is a Trans-Neptunian object circling the Sun in the Kuiper belt, discovered in 2002 by astronomers Chad Trujillo and Mike Brown at the California Institute of Technology in Pasadena, California. Quaoar is estimated to have a diameter of about 1,280 kilometres, which would make it the largest Solar System object discovered since Pluto and, indeed, the largest known minor planet. Larger than all the asteroids put together, it is about one...
