Cosmic Pearls
Two decades ago, astronomers spotted one of the brightest exploding stars in more than 400 years. Since that first sighting, the doomed star, called Supernova 1987A, has continued to fascinate astronomers with its spectacular light show. NASA’s Hubble Space Telescope…
The Colors of Saturn
This delightfully detailed false color image of Saturn is a combination of three images taken in January 1998 by the Hubble Space Telescope and shows the ringed planet in reflected infrared light. Different colors indicated varying heights and compositions of…
Burning Brightly
Images from the Hubble space Telescope, Spitzer Space Telescope and Chandra X-Ray Observatory combine to make this composite of N49, the brightest supernova remnant in optical light in the Large Magellanic Cloud. The Chandra X-ray image (blue) shows million-degree gas…
Omega Nebula: Close-Up of a Stellar Nursery
Sculpted by stellar winds and radiation, these fantastic, undulating shapes lie within the stellar nursery known as M17, the Omega Nebula, some 5,500 light-years away in the nebula-rich constellation Sagittarius. The lumpy features in the dense cold gas and dust…
Windblown
A fast and powerful wind from a hot young star created this stunning bubble-shaped nebula, poised on the end of a bright filament of hydrogen gas. Cataloged as N44F, the cosmic windblown bubble is seen at the left of this…
White Dwarf Stars
Pushing the limits of its powerful vision, NASA’s Hubble Space Telescope uncovered the oldest burned-out stars in our Milky Way Galaxy. These extremely old, dim “clockwork stars” provide a completely independent reading on the age of the universe. The ancient…
Earth, Moon, Hubble
Space Shuttle Discovery’s crew witnessed this bright full moon from orbit during a December 1999 mission that included servicing the Hubble Space Telescope (the top of which is seen on the right). To the left is Earth’s horizon; the full…
Orbiting a Red Dwarf Star
This artist’s concept of a gas giant planet orbiting a red dwarf K star shows a planet has not been directly imaged, but its presence was detected in 2003 microlensing observations of a field star in our galaxy. Gravitational microlensing…
Light Echoes From a Red Supergiant
This Hubble Space Telescope image of the star V838 Monocerotis reveals dramatic changes in the illumination of surrounding dusty cloud structures. The effect, called a light echo, unveiled never-before-seen dust patterns when the star suddenly brightened for several weeks in…
Cat’s Eye Nebula
Three thousand light-years away, the Cat’s Eye Nebula, a dying star throws off shells of glowing gas. This image from the Hubble Space Telescope reveals the nebula to be one of the most complex planetary nebulae known. In fact, the…
The Egg Nebula
Where is the center of the Egg Nebula? Like a baby chick pecking its way out of an egg, the star in the center of the Egg Nebula is casting away shells of gas and dust as it slowly transforms…
The Cat’s Eye Nebula
The full beauty of the Cat’s Eye Nebula (NGC 6543) is revealed in this new, detailed view from NASA’s Hubble Space Telescope. The image from Hubble’s Advanced Camera for Surveys (ACS) shows a bull’s eye pattern of eleven or even…
Ring Around a Star
NASA Hubble Space Telescope’s most detailed visible-light image ever taken of a narrow, dusty ring around the nearby star Fomalhaut offers the strongest evidence yet that an unruly and unseen planet may be gravitationally tugging on the ring. Hubble unequivocally…
Black Hole Bully
This composite image shows the jet from a black hole at the center of a galaxy striking the edge of another galaxy, the first time such an interaction has been found. In the image, data from several wavelengths have been…
Andromeda’s Active Core
This artist’s concept shows a view across a mysterious disk of young, blue stars encircling a supermassive black hole at the core of the neighboring Andromeda Galaxy (M31). The region around the black hole is barely visible at the center…
