Red Dwarf Stars
Astronomers were surprised to discover a 25-million-year-old protoplanetary disk around a pair of red dwarf stars 350 light-years away in the Stephenson 34 system. Gravitational stirring by the binary star system (shown in this artist’s conception) may have prevented planet…
Happy Sweet Sixteen, Hubble!
This mosaic image from NASA’s Hubble and Spitzer space telescopes and Chandra Observatory is the sharpest wide-angle view ever obtained of of the magnificent starburst galaxy, Messier 82 (M82). The galaxy is remarkable for its bright blue disk, webs of…
Dancing With the Stars
Two galaxies perform an intricate dance in this new Hubble Space Telescope image. The galaxies, containing a vast number of stars, swing past each other in a graceful performance choreographed by gravity. The pair, known collectively as Arp 87, is…
Out on a Limb

N49’s Cosmic Blast
Scattered debris from a cosmic supernova explosion lights up the sky in this gorgeous composited image based on data from the Hubble Space Telescope. Cataloged as N49, these glowing filaments of shocked gas span about 30 light-years in our neighboring…
Boomerang Nebula
The Hubble Space Telescope has “caught” the Boomerang Nebula in these new images taken with the Advanced Camera for Surveys. This reflecting cloud of dust and gas has two nearly symmetric lobes (or cones) of matter that are being ejected…
Evaporating Planet
Planet HD 209458b is evaporating. It is so close to its parent star that its heated atmosphere is simply expanding away into space. Some astronomers studying this distant planetary system now believe they have detected water vapor among the gases…
Star Cluster Bursts Out
In the center of star-forming region 30 Doradus lies a huge cluster of the largest, hottest, most massive stars known. These stars, known as the star cluster R136, and part of the surrounding nebula are captured here in this gorgeous…
Mysterious Galaxy
This image of the elliptical galaxy NGC 1132 and its surrounding region combines data from NASA’s Chandra X-ray Observatory and the Hubble Space Telescope. The blue/purple in the image is the x-ray glow from hot, diffuse gas detected by Chandra.…
Sculpting a Galaxy
This glowing region reveals arcs and bubbles formed when stellar winds – streams of charged particles ejected by the Trapezium stars – collide with material in the Orion Nebula. This crisp image is part of a tapestry of star formation…
Shells in the Egg Nebula
The Egg Nebula is taking a beating. Like a baby chick pecking its way out of an egg, the star in the center of the nebula is casting away shells of gas and dust as it slowly transforms itself into…
Galactic Dust Bunnies
The yearly ritual of spring cleaning clears a house of dust as well as dust “bunnies,” those pesky balls that frolic under beds and behind furniture. NASA’s Hubble Space Telescope has photographed similar dense knots of dust and gas in…
Galactic Building Blocks
A satellite galaxy of the Milky Way, the Small Magellanic Cloud (SMC) is a wonder of the southern sky, a mere 210,000 light-years distant in the constellation Tucana. Found among the SMC’s clusters and nebulae NGC 346 is a star…
