Asteroid 2010 SO16 takes 175 years to make the trip from one end of the horseshoe to the other. ... Currently, three other horseshoe companions of the Earth are known to exist but, unlike 2010 SO16, these linger for a few thousand years at most before moving on to different orbits. ...

... January 8, 2007 . ... SENTINEL CORRESPONDENT . Astronomers at UC Santa Cruz have discovered a surprisingly massive halo of bright, old stars around our galactic neighbor Andromeda, pushing the outer limits of the galaxy to 1.5 million light years, and teaching them how spiral galaxies behave. ... Younger stars may be remnants of a galaxy devoured, but older stars could have formed with the birth of the galaxy. ... http://www.santacruzsentinel.com/archive/2007/January/08/local/stories/03local.htm . ...

Astronomers Detect Coolest Radio Star . ... The new radio-star is much smaller and colder than our Sun.€а With a surface temperature not much higher than that of a giant planet, and a size comparable to JupiterтАЩs, it is scarcely visible in optical light.€а Yet the radio flares seen at Arecibo show it must have a strong magnetic field, implying that the same could be true of other similar stars. ...

... Over the past decade and a half, astronomers have used both ground-based and space-based telescopes to discover more than 400 "extrasolar" planets. The Kepler space-based mission uses a technique called transit photometry to search for these planets. In January 2010 the Kepler mission team announced the discovery of five new planets. ... The ultimate goal of the Kepler mission is to search out the existence of Earth-like planets. ... A Collection of Resources to Get Behind the Headlines . ...

... Moon . ... What can astronomers tell us about the different colors on the surface of Jupiter's moon Europa? ... We can use the colors of Europa s surface to tell us about the chemical compounds that make up the surface and subsurface of the jovian moon. Even before the first spacecraft made a close visit to Europa, astronomers on Earth used telescopes to study the moon and were able to use a technique called spectroscopy to determine that Europa s surface is composed mostly of water ice. ...

... Comet Tutorial . ... On July 1, 1993 an image was taken with the Hubble Space Telescope (HST) that clearly shows at least 15 individual fragments in one image frame of the train. ... This made an accurate orbit (or orbits) difficult to determine; however, after numerous observations of the comet, astronmers determined that the comet had passed within 96,000 kilometers (60,000 miles) of the center of Jupiter or 25,000 kilometers (16,000 miles) from the cloud tops during the July 8, 1992, approach. ...

... The 50 so-called exo-planets were discovered using a telescope that is found in South America. ... By looking at a star s wobble, astronomers can work out how many exo-planets are in orbit around it and how heavy they are. After studying all of the planets discovered with this telescope so far, astronomers have found that nearly half of stars that are similar to the Sun have at least one planet that is lighter than Saturn. ... But there are many, many more waiting to be found! ...

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...

Shumaker's-Levy's comet. In July 1992 the comet went in 15 thousand km near Jupiter. ... The comet was turning not around the Sun, but around Jupiter with a two-year period. During the next approaching to Jupiter in 1994 all the fragments cut into the planet’s atmosphere with the 65km/sec speed and generated the powerful disturbance of the cloudy surface. The falling was predicted by the astronomers and was observed from the Earth and from the Space. ...

... High-velocity clouds (HVCs) were discovered by Muller, Oort & Raimond (1963) in the 21-cm line emission of neutral, atomic hydrogen. They are gas clouds which are characterised by high radial velocities incompatible with a participation in the rotation of our Galaxy. ... This suggestion was seized by Braun & Burton (1999) who identified 66 compact high-velocity clouds (CHVCs) with positional and kinematic characteristics being compatible with a distribution across the entire Local Group. ...
