A new Comet Observing Planner tool has been added to the COBS website.
NASAs NEOWISE mission has completed its survey of small bodies, asteroids and comets, in our solar system. The missions discoveries of previously unknown objects include 20 comets, more than 33,000 asteroids in the main belt between Mars and Jupiter, and 134 near-Earth objects (NEOs). The NEOs are asteroids and comets with orbits that come within 45 million kilometers (28 million miles) of Earths path around the sun.
NASAs Stardust spacecraft has downlinked its first images of comet Tempel 1, the target of a flyby planned for Valentines Day, Feb. 14. The images were taken on Jan. 18 and 19 from a distance of 26.3 million kilometers (16.3 million miles), and 25.4 million kilometers (15.8 million miles) respectively. On Feb. 14, Stardust will fly within about 200 kilometers (124 miles) of the comets nucleus.
NASAs Stardust-NExT spacecraft is nearing a celestial date with comet Tempel 1 at approximately 11:37 p.m. EST, on Feb. 14. The mission will allow scientists for the first time to look for changes on a comets surface that occurred following an orbit around the sun.
Comet C/2011 A3 (Gibbs) was discovered on 2011, Jan. 15.51 by Alex Gibbs (during the course of the Catalina Sky Survey) in four 22-sec exposures taken with the 0.68-m Schmidt on Mt.Bigelow.
The sun has just experienced a storm—not of explosive flares and hot plasma, but of icy comets.
On February 14, 2011, NASAs Stardust-NExT (New Exploration of Tempel 1) mission will encounter Comet Tempel 1, providing a unique opportunity to measure the dust properties of two separate comets (Wild 2 and Tempel 1) with the same instrument for accurate data comparison. The encounter will also provide a comparison between two observations of a single comet, Tempel 1, taken before and after a single orbital pass around the sun.
As people on Earth celebrate the holidays and prepare to ring in the New Year, an ESA/NASA spacecraft has quietly reached its own milestone: on December 26, the Solar and Heliospheric Observatory (SOHO) discovered its 2000th comet.
A new feature has been added to COBS analysis page enabling the observer to plot the date of perihelion on the lightcurve graph.
It does not look like much now — just a 19th-magnitude smudge tucked away in southwestern Virgo — but a newly discovered comet could become something special 10 months from now.
