Deep inside the Hyades star cluster, a pair of burned-out stars are yielding clues to the presence of rocky planets that may have whirled around them. Asteroid debris is 'raining' into the hot atmospheres of these white dwarfs. Asteroids should consist of the same material that form terrestrial planets, and seeing evidence of asteroids points to the possibility of Earth-sized planets in the same system.

NASA's Hubble Space Telescope has found the building blocks for Earth-sized planets in an unlikely place-- the atmospheres of a pair of burned-out stars called white dwarfs.

The Space Telescope Science Institute has appointed Dr. Massimo Stiavelli as the James Webb Space Telescope (JWST) Mission Head. Stiavelli will be responsible for the development and operations of the JWST Science and Operations Center at STScI. He has been acting JWST Mission Head since January 2012. The largest space observatory ever developed, JWST is scheduled for launch in 2018. Stiavelli succeeds Dr. Kathy Flanagan, who was appointed the Institute's Deputy Director in October 2012. Stiavelli has worked at the Institute for over 17 years. His many positions at the Institute include instrument scientist for three Hubble cameras. Stiavelli has been working on the JWST project since 1996.

Comet ISON is potentially the "comet of the century" because around the time the comet makes its closest approach to the Sun, on November 28, it may briefly become brighter than the full Moon. Right now the comet is far below naked-eye visibility, and so Hubble was used to snap the view of the approaching comet, which is presently hurtling toward the Sun at approximately 47,000 miles per hour. When the Hubble picture was taken on April 10, the comet was slightly closer than Jupiter's orbit at a distance of 386 million miles from the Sun. Even at that great distance the Sun is warming the comet enough to trigger outgassing from its frozen gases locked up in the solid nucleus. Hubble photographed a jet blasting dust particles off the sunward-facing side of the comet's nucleus. Preliminary measurements from the Hubble images suggest that the nucleus of ISON is no larger than three or four miles across. The comet was discovered in September 2012 by the Russian-led International Scientific Optical Network (ISON) using a 16-inch telescope.

New views of the Horsehead Nebula and its turbulent environment have been unveiled by ESA’s Herschel space observatory and the NASA/ESA Hubble space telescope.
Fri, 19 Apr 2013 08:50:00 -0400
Unlike other celestial objects there is no question how the Horsehead Nebula got its name. This iconic silhouette of a horse's head and neck pokes up mysteriously from what look like whitecaps of interstellar foam. The nebula has graced astronomy books ever since its discovery over a century ago. But Hubble's infrared vision shows the horse in a new light. The nebula, shadowy in optical light, appears transparent and ethereal when seen at infrared wavelengths. This pillar of tenuous hydrogen gas laced with dust is resisting being eroded away by the radiation from a nearby star. The nebula is a small part of a vast star-forming complex in the constellation Orion. The Horsehead will disintegrate in about 5 million years.

Astronomers have used NASA's Hubble Space Telescope to photograph the iconic Horsehead Nebula in a new, infrared light to mark the 23rd anniversary of the famous observatory's launch aboard the space shuttle Discovery on April 24, 1990.

ESA’s Herschel space observatory has discovered an extremely distant galaxy making stars more than 2000 times faster than our own Milky Way. Seen at a time when the Universe was less than a billion years old, its mere existence challenges our theories of galaxy evolution.

A long time ago, in a galaxy far, far away, a star detonated with enough energy to briefly shine with an intrinsic brightness of one billion of our suns. The beacon of radiation arrived at Earth 10 billion years later and was captured in a Hubble Space Telescope deep survey of the universe. It is the farthest, and earliest, supernova of its type detected to date. More than simply an example of the ancient fireworks in the young and effervescent universe, the supernova belongs to a special class of stellar detonations that are so reliably bright, they can be used as intergalactic milepost markers.

NASA's Chandra X-ray telescope has made the first detection of X-ray emission from young solar-type stars that lie outside our Milky Way galaxy. They live in a region known as the "Wing" of the Small Magellanic Cloud, a satellite galaxy of our Milky Way. X-rays from young stars trace how active their magnetic fields are. Magnetic activity provides clues to a star's rotation rate and the rising and falling of hot gas in the star's interior. Astronomers suggest that if the X-ray properties of young stars are similar in different environments around our galaxy, then other related properties, such as the formation of planets, are also likely to be similar.

Astronomers have watched as a black hole woke up from a decades-long slumber to feed on a low-mass object – either a brown dwarf or a giant planet – that strayed too close. A similar feeding event, albeit on a gas cloud, will soon happen at the black hole at the centre of our own Milky Way Galaxy.

You can't be older than your parents. But there is a nearby star that at first glance looks like it is older than the universe! Hubble Space Telescope astronomers are coming to grips with this paradox by improving the precision of the observations used to estimate the age of this "Methuselah star."

The universe is eerie enough without giving us an apparition of a 1980s video game alien attacker. This oddball-looking object is really a mirage created by the gravitational field of a foreground cluster of galaxies warping space and distorting the background images of more distant galaxies.
