Comet ISON: How to See Potential 'Comet of the Century' Online Today
The much-anticipated incoming Comet ISON, which some scientists hope will become the "comet of the century" later this year, may not be visible to the naked eye yet, but you don't have to wait months to see this icy wanderer. The comet takes center stage in an online telescope webcast today (May 19).
Comet ISON was first discovered last year and is currently expected to swing extremely close by the sun in late November, when it will be at its best and brightest of the year. In anticipation of the comet's arrival, the online Slooh Space Camera will offer live telescope views of the object beginning at 4:45 p.m. EDT (2045 GMT).
Today's webcast marks Slooh's fourth monthly webcast dedicated to tracking Comet ISON's progress through the solar system. During today's 30-minute live show, Slooh officials will provide views of Comet ISON from the firm's remotely operated telescopes in the Canary Islands, off the west coast of Africa.
Senior space scientist Padma Yanamandra-Fisher of the Space Science Institute in Boulder, Colo., will join Slooh producer Paul Cox in the comet webcast. Yanamandra-Fisher is helping coordinate NASA's Comet ISON Observing Campaign to track the comet. The international campaign is bringing together scientists around the world to plan out observations of ISON.
NASA has already used several spacecraft, including sun-watching Stereo probes and the Hubble Space Telescope, to observe ISON. An unmanned balloon mission is also among the expeditions planned to observe ISON.
Comet ISON has drawn worldwide attention from stargazers and scientists, including NASA, because of its close approach to the sun on Nov. 28, when it will be just 730,000 miles (1.2 million kilometers) from the sun. During that close encounter with the sun, Comet ISON could become one of the brightest comets in decades. However, the comet could also fizzle out.
Comet ISON was discovered in September 2012 by Russian amateur astronomers Artyom Novichonok and Vitali Nevski using the International Scientific Optical Network (ISON) of remotely operated telescopes. The comet is officially known by the identification C/2012 S1 (ISON).
On April 10, scientists used the Hubble Space Telescope to observe Comet ISON. At the time it was about 386 million miles (621 million kilometers) from the sun and 394 million miles (634 million kilometers) from Earth.
When observed by Hubble, the comet's nucleus was about 3 miles (5 km) across and a dusty tail that stretches more than 57,000 miles (92,000 km) long.
