A Star Forming Region in the LMC
25.06.1996
Stars sometimes form in colorful ways. Pictured above is a small region in the nearby LMC galaxy where stars are forming. After a star is born, it may do several things to energize its immediate neighborhood.
A Quasar in the Gamma Ray Sky
17.11.1996
The bright object in the center of the false color image above is quasar 3C279 viewed in gamma-rays, photons with more than 40 million times the energy of visible light. Like all quasars, 3C279 is a nondescript, faint, starlike object in the visible sky.
Shadow Rise
22.08.2003
As the Sun sets, the Earth's shadow rises up from the east. The subtle beauty of this daily apparition is often overlooked in favor of the brighter, more colorful western horizon. But while...
Moon Occults Saturn
8.09.2001
On September 18, 1997, many stargazers in the U. S. were able to watch a lovely early morning lunar occultation as a bright Moon passed in front of Saturn. Using a 1.2 meter reflector, astronomer Kris Stanek had an excellent view of this dream-like event from the Whipple Observatory atop Arizona's Mount Hopkins.
At the Edge of the Helix
22.04.1996
While exploring the inner edge of the Helix Nebula with the Hubble Space Telescope's Wide Field Planetary Camera 2, astronomers were able to produce this striking image - rich in details of an exotic environment.
NGC 3242: The 'Ghost of Jupiter' Planetary Nebula
31.03.1997
It's a weed, it's Jupiter, no it's - actually planetary nebula NGC 3242. After a star like our Sun completes fusion in its core, it throws off its outer layers it a striking display called a planetary nebula.
At the Edge of the Helix
20.07.1997
While exploring the inner edge of the Helix Nebula with the Hubble Space Telescope's Wide Field Planetary Camera 2, astronomers were able to produce this striking image - rich in details of an exotic environment.
Fractal Interstellar Dust Up Close
4.01.1998
Our universe is a very dusty place. Dust usually shows its presence by blocking out light emitted from stars or nebulae behind it, sometimes creating the illusion of a horse's head or a sombrero hat. But nobody really knows what a typical interstellar dust grain looks like.
Two Comets in Southern Skies
27.05.2004
Wielding a very wide-angle lens, astronomer Gordon Garradd was able to capture two naked-eye comets in one picture looking toward the west from Loomberah, New South Wales, Australia. At the far left lies comet C/2002 T7 (LINEAR) and at the far right, comet C/2001 Q4 (NEAT).
Spiral Galaxies in Collision
21.11.2004
Billions of years from now, only one of these two galaxies will remain. Until then, spiral galaxies NGC 2207 and IC 2163 will slowly pull each other apart, creating tides of matter, sheets of shocked gas, lanes of dark dust, bursts of star formation, and streams of cast-away stars.
