Hubble Catches Jupiter Changing Its Stripes

Massive Jupiter is undergoing dramatic atmospheric changes that have never been seen before with the keen "eye" of NASA's Hubble Space Telescope.

Jupiter's turbulent clouds are always changing as they encounter atmospheric disturbances while sweeping around the planet at hundreds of miles per hour. But these Hubble images reveal a rapid transformation in the shape and color of Jupiter's clouds near the equator, marking an entire face of the globe.

Stellar Fireworks Are Ablaze in Galaxy NGC 4449

	On July 4, fireworks blaze over the skies of American cities in the annual Independence Day celebrations. But nearly 12.5 million light-years away in the dwarf galaxy NGC 4449 stellar "fireworks" are going off all the time. The image was taken in November 2005 with Hubble's Advanced Camera for Surveys.

Gruber Cosmology Prize Awarded to STScI Dark Energy Discoverers

Four astronomers at the Space Telescope Science Institute in Baltimore, Md. are on two teams sharing the $500,000 2007 Gruber Cosmology Prize for their discovery that the expanding universe is accelerating under a mysterious cosmic force called dark energy.

The astronomers are Andrew Fruchter (top left), Ron Gilliland (top right), Nino Panagia (bottom left), and Adam Riess (bottom right). Gilliland and Riess are on the High-z Supernova Search Team led by Brian Schmidt of the Australian National University. Fruchter and Panagia are on the Supernova Cosmology Project led by Saul Perlmutter of the University of California at Berkeley.

Astronomers Find Highly Elliptical Disk Around Young Star

hubblesite on 11/06/2007 at 7:46am (UTC)

Dust and debris parade in an extremely misshapen ring around the young star, HD 15115. The disk, seen edge-on with NASA's Hubble Space Telescope, is the dense blue line extending from the star to the upper right and lower left of the image. The disk appears thicker at upper right than at lower left, evidence of its lopsided structure. Astronomers think the disk's needle-like look is caused by dust particles following a highly elliptical orbit around the star. The lopsidedness may have been caused by planets sweeping up debris in the disk or by the gravity of a nearby star. An occulting mask on Hubble's Advanced Camera for Surveys was used to block out the bright starlight in order to see the dim disk. The occulting masks can be seen in the image as the dark circle in the center and the dark bar on the left. The star is behind the central mask. The Hubble image was taken on July 17, 2006. Follow-up observations in 2006 and 2007 with the W.M. Keck Observatory

Uncovering the Veil Nebula

NASA's Hubble Space Telescope photographed three magnificent sections of the Veil Nebula -- the shattered remains of a supernova that exploded thousands of years ago. This series of images provides beautifully detailed views of the delicate, wispy structure resulting from this cosmic explosion. The Veil Nebula is one of the most spectacular supernova remnants in the sky. The entire shell spans about 3 degrees on the sky, corresponding to about 6 full moons.
