Latest research has concluded that the Tunguska explosion was almost certainly caused by a comet entering the Earth's atmosphere. And how researcher Michael Kelly from Cornell University came to that conclusion is quite interesting: He analyzed the space shuttle's exhaust plume and noctilucent clouds.

Satellite information on incoming meteors is blocked.

IAUC Circular No. 9052, issued on 2009, June 16, announces the discovery by Rui Yang and Xing Gao of a new comet on several survey images taken by Gao in the course of the Xingming Comet Survey at Mt. Nanshan using a Canon 350D camera (+ 10.7-cm f/2.8 camera lens).

We present thermal observations of 44 Jovian Trojan asteroids with diameters (D) ranging from 5 to 24 km.

A comet hunt on the morning of May25th turns up a previously discovered comet with a interesting history.

Fist-sized stones scattered around Victoria Crater on Mars appear to be meteorites - and might be fragments of the object that punched out the crater, researchers say.

Due to close encounters with the inner planets, Near-Earth-Asteroids (NEAs) can have very chaotic orbits. Because of this chaoticity, a statistical treatment of the dynamical properties of NEAs becomes difficult or even impossible. We propose a new way to classify NEAs by using methods from Fuzzy Logic.

We have performed a simulation of a next generation sky survey's (Pan-STARRS 1) efficiency for detecting Earth-impacting asteroids.

Celestial impacts can bring life as well as wipe it out, say the authors of a new study out of the University of Colorado at Boulder.

During 2006 Mar - 2007 Jan, we used the IRAC and MIPS instruments on the Spitzer Space Telescope to study the infrared emission from the ensemble of fragments, meteoroids, and dust tails in the more than 3 degree wide 73P/Schwassmann-Wachmann 3 debris field.

Secondary "condensation" in 19P/Borrelly, we performed some follow-up about this comet........

A newly discovered asteroid designated 2009 VA, which is only about 7 meters in size, passed about 2 Earth radii (14,000 km) from the Earth's surface Nov. 6 at around 16:30 EST. This is the third-closest known (non-impacting) Earth approach on record for a cataloged asteroid.

On Nov. 18, just after midnight local time (MST) a great fireball was seen over parts of the western United States

According to preliminary counts from the International Meteor Organization (IMO) the Leonids meteors reached a ZHR(max) ~ 120/130 around 22UT of Nov. 17, as predicted by forecasters.

A bright fireball has been seen over Wisconsin aroud 10:00 p.m. local time of April 14, 2010. The fireball has been seen from Wisconsin to Missouri. National Weather Service offices in La Crosse, Wisconsin, Davenport and Des Moines, Iowa, and St. Louis and Kansas City in Missouri all received numerous reports.
