It began with a furrowed brow, a moment of puzzlement, quickly dismissed. The date was July 19, 2009. Amateur astronomer Anthony Wesley was photographing Jupiter from his backyard observatory in Murrumbateman, Australia, when something odd caught his eye. "My attention was fixed on the Great Red Spot, which was setting beautifully over Jupiter's horizon," recalls Wesley. "I almost didn't notice the dark blemish near Jupiter's south pole, and when I did, I put it out of my mind." It's just...

BALTIMORE, July 24 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has taken the sharpest visible-light picture yet of atmospheric debris from an object that collided with Jupiter on July 19. NASA scientists decided to interrupt the recently refurbished observatory's checkout and calibration to take the image of a new, expanding spot on the giant planet on July 23.

The checkout and calibration of the NASA/ESA Hubble Space Telescope has been interrupted to aim the recently refurbished observatory at a new expanding spot on the giant planet Jupiter. The spot, caused by the impact of a comet or an asteroid, is changing from day to day in the planet's cloud tops. For the past several days the world's largest telescopes have been trained on Jupiter. Not to miss the potentially new science in the unfolding drama 580 million kilometers away, Matt Mountain,...

A team of astronomers using the Gemini North telescope on Mauna Kea in Hawai'i obtained a new infrared image of Jupiter on Wednesday night, July 22, showing its new scar still glowing in mid-infrared wavelengths. The image complements earlier infrared images, including two taken July 20, shortly after the bruise was noticed, with the Keck II telescope and NASA's Infrared Telescope Facility "” both a stone's throw from the Gemini telescope on Mauna Kea. Jupiter's new glowing bruise, some...

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...

ALBUQUERQUE, N.M. -- The stunning amount of forest devastation at Tunguska a century ago in Siberia may have been caused by an asteroid only a fraction as large as previously published estimates, Sandia National Laboratories supercomputer simulations suggest. "The asteroid that caused the extensive damage was much smaller than we had thought," says Sandia principal investigator Mark Boslough of the impact that occurred June 30, 1908. "That such a small object can do this kind of...

By DAN SORENSON 'Amateur' astronomer, citizen scientist Famed Tucson astronomer and comet hunter David Levy's future was in the stars. Dimly. Barely visible. Levy says he was 8 years old and walking back to his cabin at summer camp. "I happened to be looking up at the dark sky and I saw a little shooting star. It wasn't much of anything, but it lit a spark in me," Levy says. "I asked my cabin mates if they saw it, and they didn't, and I thought, 'This is just for me.' " Then, nothing -...

As the fragments of shattered comet 73P/Schwassmann Wachmann 3 glide harmlessly past Earth this month in full view of backyard telescopes, onlookers can't help but wonder, what if a comet like that didn't miss, but actually hit our planet? For the answer to that question, we look to the Sahara desert. In a remote windswept area named Aorounga, in Chad, there are three craters in a row, each about 10 km in diameter. "We believe this is a 'crater chain' formed by the impact of a fragmented...

Ten days after part of the Deep Impact spacecraft plunged onto Comet Tempel 1 with the aim to create a crater and expose pristine material from beneath the surface, astronomers are back in the ESO Offices in Santiago, after more than a week of observing at the ESO La Silla Paranal Observatory. In this unprecedented observing campaign - among the most ambitious ever conducted by a single observatory - the astronomers have collected a large amount of invaluable data on this comet. The...

Jupiter -- in astronomy, fifth planet from the sun and largest planet of the solar system. Astronomical and Physical Characteristics Jupiter's orbit lies beyond the asteroid belt at a mean distance of 483.6 million mi (778.3 million km) from the sun; its period of revolution is 11.86 years. In order from the sun it is the first of the Jovian planetsJupiter, Saturn, Uranus, and Neptunevery large, massive planets of relatively low density, having rapid rotation and a thick, opaque...

Near-Earth Asteroid -- Near-Earth asteroids (NEAs) are asteroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger, as well as being most easily accessible for spacecraft from Earth. In fact, some near-Earth asteroids can be reached with much less ΔV than the Moon. The most famous near-Earth asteroid is 433 Eros that was visited by NASA's Near Earth Asteroid Rendezvous probe. A few hundred such near-Earth asteroids are known, ranging in size up...

Comet Shoemaker-Levy 9 -- Comet Shoemaker-Levy 9 is so-named because it was the ninth short-period comet discovered by Carolyn and Eugene Shoemaker and David Levy. It was first detected in a photograph taken on the night of March 24, 1993 with the 0.4-meter Schmidt telescope at the Mount Palomar observatory in California, and subsequently observed by many other astronomers. The comet was extremely unusual because it was in fragments, evidently due to a close encounter with the planet...
