Hubble Peers Inside a Celestial Geode
536
Hubble Space Telescope -- In this unusual image, NASA's Hubble Space Telescope captures a rare view of the celestial equivalent of a geode Ã¢ÂÂ a gas cavity carved by the stellar wind and intense ultraviolet radiation from a hot young star.    Real geodes are baseball-sized, hollow rocks that start out as bubbles in volcanic or sedimentary rock...

A telescope with a 4-inch diameter -- about the size that some backyard astronomers might use -- tracked the periodic dimming of light from a bright star 500 light-years away.

A University of Colorado study has embarked on demonstrating that new planets can be found with the help of an orbiting starshade. The method has been compared to building a giant pinhole camera in space.

Perched on the top of one of Mexico's highest mountains is a gigantic, half-built telescope that scientists hope will reveal more secrets of the universe's early years than any before it.

When scientists are looking into space, the more they can see, the easier it is to piece together the puzzle of the cosmos. The James Webb Space Telescope's mirror blanks have now been constructed.

In this detailed view from NASA&#39;s Hubble Space Telescope, the so-called Cat&#39;s Eye Nebula looks like the penetrating eye of the disembodied sorcerer Sauron from the film adaptation of &quot;The Lord of the Rings.

An orbiting NASA telescope that scans the heavens has found evidence of massive "baby" galaxies that runs counter to a belief that only small new galaxies are being formed by the aging universe.

The Hubble Space Telescope has looked into a bubble of gas and dust being inflated by a young star's particles.

By Bill OrdinePerhaps from space, this wondrous blue orb suspended in the cosmos has such a oneness to it that the difference between Baltimore and, oh, let's say Indianapolis, doesn't appear so great.

US scientists working with images from the Hubble Space Telescope have identified what may turn out to be some of the earliest star-forming galaxies.

Astronomers have stumbled upon a tremendous hole in the universe. That's got them scratching their heads about what's just not there. The cosmic blank spot has no stray stars, no galaxies, no sucking black holes, not even mysterious dark matter. It is 1 billion light years across of nothing. That's an expanse of nearly 6 billion trillion miles of emptiness, a University of Minnesota team announced Thursday.

Hubble Space Telescope -- Hubble Space Telescope -- Detailed analyses of mankind's deepest optical view of the universe, the Hubble Ultra Deep Field (HUDF), by several expert teams have at last identified what may turn out to be some of the earliest star-forming galaxies.     Astronomers are now debating whether the hottest stars in these early galaxies may have provided enough radiation to "lift a curtain" of cold, primordial hydrogen that cooled after the big bang...

Astronomers using NASA's Hubble Space Telescope have photographed one of the smallest objects ever seen around a normal star beyond our Sun. Weighing in at 12 times the mass of Jupiter, the object is small enough to be a planet.

A NASA-led team is studying the construction of a railway in space for a pair of telescopes that will provide views of planet, star, and galaxy formation in unprecedented detail. The proposed Space Infrared Interferometric Telescope (SPIRIT) mission will also examine the atmospheric chemistry of giant planets around other stars.

NASA engineers Monday were examining a problem with the Hubble Space Telescope's Advanced Camera for Surveys. National Aeronautical and Space Administration officials say the observatory was placed in a protective safe mode at 7:34 a.m.
