NASA Stardust Adjusts Flight Path for Comet Meetup
February 02, 2011
Just over two weeks before its flyby of comet Tempel 1, NASAs Stardust spacecraft fired its thrusters to help refine its flight path toward the comet. The Stardust-NExT mission will fly past comet Tempel 1 on Valentines Day (Feb. 14, 2011).

NASAs NEOWISE Completes Scan for Asteroids and Comets
February 01, 2011
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.
NASA Comet Hunter Spots Its Valentine
January 27, 2011
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.
NASA Spacecraft prepares for Valentins Day Comet rendezvous
January 21, 2011
NASAs Stardust-NExT spacecraft is nearing a celestial date with comet Tempel 1 at approximately 11:37 p.m. EST, on Feb. 14.

New comet C/2011 A3 (Gibbs)
January 18, 2011
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.
Sundiving Comet Storm
January 14, 2011
The sun has just experienced a storm—not of explosive flares and hot plasma, but of icy comets.
A Valentines Day Return to Comet Tempel 1
January 13, 2011
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.

Comet C/2010 U3 (Boattini)
November 07, 2010
A. Boattini reports his discovery of a faint comet with a moderately
diffuse coma that is 6"-7" wide and a central condensation that is about

Lemmon 1.5-m reflector in Arizona.
EPOXI Visits Hartley 2
November 05, 2010
This morning EPOXI, the spacecraft formerly known as Deep Impact, flew within 435 miles (700 km) of the nucleus of Comet 103P/Hartley 2. Images taken during the encounter are being downloaded from the spacecraft throughout the day. A few of the images have been released by the EPOXI team and can be found here.
