COMET ISON UPDATE: In November 2013, Comet ISON could become one of the brightest and most active comets in years when it races through the hot atmosphere of the s*n. Right now, though, it is just a dim speck in the deep-freeze of space near the orbit of Jupiter. Alberto Quijano Vodniza photographed the barely-visible comet on April 7th from his private observatory in Pasto, Narino, Colombia:



Comet ISON may look underwhelming, but that is only because it is so far away, more than 400 million miles from the s*n. In fact, it is already an active comet with considerable promise. Recent measurements by NASA's Swift spacecraft shows that the comet's nucleus is spewing more than 112,000 pounds (51,000 kg) of dust, or about two-thirds the mass of an unfueled space shuttle, every minute. To produce so much dust, the comet's nucleus is probably about 5 km wide. For comparison, the nucleus of bright sungrazing Comet Lovejoy, which wowed observers in 2011, was only about one-tenth as large. Comet ISON could put on quite a show when it approaches the s*n later this year.
