(Â鶹ÒùÔº)—An international team of researchers led by Martin Cordiner of NASA's Goddard Space Flight Center has conducted measurements of CH3OH (methanol) emission from comet C/2012 K1 (PanSTARRS) that could yield invaluable ...
(Â鶹ÒùÔº)—WD 1145+017, a white dwarf star located some 570 light years from the Earth, captured the attention of astronomers last year, when evidence suggested that a rocky object orbiting it was being ripped apart. It ...

The vast Kuiper Belt, which orbits at the outer edge of our solar system, has been the site of many exciting discoveries in the past decade or so. Otherwise known as the Trans-Neptunian region, small bodies have been discovered ...
In the 18th century, observations made of all the known planets (Mercury, Venus, Earth, Mars, Jupiter and Saturn) led astronomers to discern a pattern in their orbits. Eventually, this led to the Titius–Bode law, which ...
The term dwarf planet has been tossed around a lot in recent years. As part of a three-way categorization of bodies orbiting the sun, the term was adopted in 2006 due to the discovery of objects beyond the orbit of Neptune ...
