Jose Luis Ortiz of Sierra Nevada Observatory has seemingly found a very large Trans Neptunian object while checking out some old images from their TNO survey that was started in 2002. They managed to recover the object on the 29th from the Observatorio Astronomico de Mallorca. They measure...

Researchers say they have found the first evidence that the frozen outer reaches of our solar system could be littered with many more objects than we think. Astronomers have been trying to get a picture of the region, known as the Kuiper belt, because it is believed to contain debris from the birth o...

Astronomers have produced a new colour map of Pluto, the most distant planet in our Solar System, using images from the Hubble Space Telescope. The detailed map shows areas likely to be methane frost and a bright spot perhaps made of frozen carbon monoxide. [img]http://www.geocities.com/...

The object designated 2003 VB12 was discovered with the Palomar 1.2-m Schmidt telescope on November 14, 2003 and has also been found on sky photographs taken in 2001 and 2002. Orbit computations show that the object's distance from the Sun varies between 76 and about 900 Astronomical Units. Its cur...

By means of high-precision timing thanks to pulsars astronomers now know what the solar barycentre is doing with respect to the rest of the cosmos. And it is not being pulled around by Planet X. So there is nothing out there within worrying distance. The astronomers, Nadia Zakams...

Occultation of C313.2 by Charon On July 11 2005, Scientists from MIT (Cambridge, Mass.) and Williams College (Williamstown, Mass.) observed Pluto's moon, Charon, occult the star C313.2. "We have been waiting many years for this opportunity. Watching Charon appr...

Asteroid 136472 (2005 FY9) 2003 EL61 and 2003UB313 orbits 52 AU from the Sun. 2005 FY9 is estimated to have an absolute magnitude of -0.4; with a Pluto-like albedo of 0.6 this would give it a diameter that is slightly less than the diameter of Pluto, about 1990km. But if it's darker (Sedna is ~ 0.1) then i...

Astronomers discover a binary system that boasts the widest separation known in the solar system Long-distance relationships are tough enough when partners are a continent apart. Consider the plight of two solar system bodies separated by a distance more than 20 times as great. Astronomers have...

A team of astronomers working in Canada, France and the United States have discovered an unusual small body orbiting the Sun beyond Neptune, in the region astronomers call the Kuiper belt. This new object is twice as far from the Sun as Neptune and is roughly half the size of Pluto. The body's highly un...
