It appears Northern California got a bit of its own celestial excitement, as people across the area reported seeing a bright light shoot through the sky Friday night.

The Associated Press reports the Chabot Space and Science Center in Oakland received calls describing what appeared to be a fireball flying west Friday night, but it's not clear what the object was.

2013 Comets

Comet Nevski-Novichonok (ISON) as it may appear at sunset on Nov. 29, if it survives its close encounter with the sun the day before.

The year 2013 may someday be known as "the year of the comets." If all goes well we may see two of the brightest comets in many years, and possibly one of the brightest in history.

However, astronomers are being very cautious in their predictions because of past disappointments. As comet specialist David Levy says, "Comets are like cats; they have tails, and they do precisely what they want."

The Watchers - 2/17/13, By Chillymanjaro

Alexander Belousov and Marina Belousova, researchers at Russia’s Institute of Volcanology and Seismology, lowered a camera into six geysers in the famed Valley of the Geysers on Russia’s volcanic Kamchatka Peninsula. The results provide a new model for understanding how geysers work (The study was published online January 25 in the journal Geology).   The videos, combined with studies of rocks surrounding extinct geysers, revealed that the Kamchatka geysers aren’t fed by long, narrow tubes, as once thought. Bubble traps form between jumbled boulders deposited by landslides.  The videos show boulders and burbling bubbles while the geyser rests, then bursts of steam during...

This exceptional sequence bellow by Virtual Telescope, shows asteroid 2012 DA14, soon after its close approach at about 27500km above the Earth surface. At the imaging time, it was moving at the amazing rate of 2450″/min (0.7deg/min)! The robotic telescope was carefully tuned to track its rapidly changing apparent motion. Asteroid was only 20 degrees above the horizon.   AGI aerospace engineers have used Systems Tool Kit (STK) software to create a simulation based on publically available information showing the trajectory of the meteor, as well as the trajectory of asteroid 2012 DA14, which had a close approach same day....

MONTREAL—People walking through Angrignon Park made a disturbing discovery on Friday: hundreds of fish, most of them dead, were trapped in a small, shallow part of grand lac.

Those that are still alive are struggling to get out.

It's not clear how the fish became trapped or why many of them have died.

The anticipation for comet C/2011 L4 (PANSTARRS) is running high as the time draws near when it expected to brighten to naked-eye visibility. If it responds as expected, it would be the brightest comet in six years.

C/2011 L4 is a non-periodic comet discovered in June 2011 that is expected to be visible to the naked eye near the time of its perihelion on March 10. The southern hemisphere will get a view of its closest approach to Earth on March 5. It should be visible to northern hemisphere observers between March 12 and March 24.

It was during the noon hour Mountain Time, that Asteroid 2012 DA14 approached and passed Earth Friday, February 15. Its path went in a general south to north direction.

It didn’t hit any satellites and it didn’t stay around very long. The video from Australia, where it was 2 a.m. shows a streak crossing the sky. The asteroid appears as a streak because the telescope was focused on the stars.

Preliminary estimates put the size of the rock at half the size of a football field. This is from the Gingin Observatory.
