Asteroid Watch NASA to Provide Web Updates on Objects Approaching Earth
NASA's Jet Propulsion Laboratory is introducing a new Web site that will provide a centralized resource for information on near-Earth objects - those asteroids and comets that can approach Earth.

This is timely as we are reminded that asteroids and comets can hit planets.
Remember the Shoemaker - Levy 9 collisions with Jupiter?

Comet Shoemaker-Levy 9 (SL9, formally designated D/1993 F2) was a comet that broke apart and collided with Jupiter in July of 1994, providing the first direct observation of an extraterrestrial collision of solar system objects.[1] This generated a large amount of coverage in the popular media, and SL9 was closely observed by astronomers worldwide. The collision provided new information about Jupiter and highlighted its role in reducing space debris in the inner solar system.
The comet was discovered by astronomers Carolyn and Eugene M. Shoemaker and David Levy. Shoemaker-Levy 9 was located on the night of March 24, 1993, in a photograph taken with the 0.4 m (1.3 ft) Schmidt telescope at the Palomar Observatory in California. It was the first
comet observed to be orbiting a planet.

Jupiter: Our Cosmic Protector?
By DENNIS OVERBYE
Published: July 25, 2009
Jupiter took a bullet for us last weekend
An object, probably a comet that nobody saw coming, plowed into the giant planet’s colorful cloud tops sometime Sunday, splashing up debris and leaving a black eye the size of the Pacific Ocean. This was the second time in 15 years that this had happened. The whole world was watching when Comet Shoemaker-Levy 9 fell apart and its pieces crashed into Jupiter in 1994, leaving Earth-size marks that persisted up to a year.

All Eyes on Jupiter
What an incredible few hours it’s been for astronomers everywhere, as we witness a chance of a lifetime event: evidence of a space rock of some sort slamming into Jupiter. Images taken after the impact show the debris field and aftermath of a gigantic collision that occurred in the southern polar region of the enormous planet.
An extremely dedicated and meticulous team of amateur astronomers observe Jupiter’s changing cloud patterns on a regular basis, and it came as an amazing surprise when Anthony Wesley, near Canberra, Australia, reported his Sunday-morning (July 19, 2009) observations

Maybe you will be able to take advantage of the new web site.
More eyes looking up, good.

Thanks for looking up with me.

NASA to Provide Web Updates on Objects Approaching Earth
PASADENA, Calif. -- NASA's Jet Propulsion Laboratory is introducing a new Web site that will provide a centralized resource for information on near-Earth objects those asteroids and comets that can approach Earth. The "Asteroid Watch" site also contains links for the interested public to sign up for NASA's new asteroid widget and Twitter account.
"Most people have a fascination with near-Earth objects," said Don Yeomans, manager of NASA's Near-Earth Object Program Office at JPL. "And I have to agree with them. I have studied them for over three decades and I find them to be scientifically fascinating, and a few
are potentially hazardous to Earth. The goal of our Web site is to provide the public with the most up-to-date and accurate information on these intriguing objects."

Jupiter Pummeled, Leaving Bruise The Size Of Pacific Ocean
ScienceDaily (July 21, 2009) — Scientists have found evidence that another object has bombarded Jupiter, exactly 15 years after the first impacts by the comet Shoemaker-Levy 9.
Following up on a tip by an amateur astronomer, Anthony Wesley of Australia, that a new dark "scar" had suddenly appeared on Jupiter, this morning between 3 and 9 a.m. PDT (6 a.m. and noon EDT) scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif., using NASA's
Infrared Telescope Facility at the summit of Mauna Kea, Hawaii, gathered evidence indicating an impact.
New infrared images show the likely impact point was near the south polar region, with a visibly dark "scar" and bright upwelling particles in the upper atmosphere detected in near-infrared
wavelengths, and a warming of the upper troposphere with possible extra emission from ammonia gas detected at mid-infrared wavelengths.
"We were extremely lucky to be seeing Jupiter at exactly the right time, the right hour, the right side of Jupiter to witness the event. We couldn't have planned it better," said Glenn Orton, a scientist at JPL.
