Black Holes Light Up
Not even light can escape a
black hole's grip, but gas
falling into a black hole
can heat up and become an
intense source of X-rays, at
temperatures up to 1,000
times hotter than the sun.
Astronomers use the Chandra

The Mystery of Black Holes
A satellite called Swift is
revealing that black holes
have a messier birth than
previously thought. Instead
of being created in one
instant, astrophysicists now
believe after a star dies

First Stars In The Universe
Astronomers removed light
from closer and better known
galaxies and stars from
pictures taken with the
Spitzer Space Telescope. The
remaining images are
believed to be the first

Astronomers Explain Reason For Narrowing Rings Of Saturn
Astronomers say that Saturn's rings will disappear from view on Earth on September 4, 2009. The gases, ice, and rocky material that make up the rings will remain in place, but be invisible from the ... > more -
Astronomers Explain New Double Star In Western Sky
Astronomers say that this July planetary orbits have lined up so that people on Earth can see a rare convergence of Venus and Saturn in the night sky. Just after sunset they will appear in the west, ... > more -
Astrophysicists Search Skies For A Moon Like Earth's
Astrophysicists used the Spitzer Space Telescope to scan a cluster of about 500 stars for evidence of a collision similar to the one that produced Earth's moon. The telescope searches in the infrared ... > more -
Astronomers Need Your Help To Find Planets Outside Our Solar System
A new distributed computing program analyzes data to characterize new planetary systems by computing the light reflected from nearby extrasolar planets and the wobble the planets cause in their stars ... > more -
Astronomers Discover Eight New Gravitational Lenses with Hubble Telescope
Images from the Hubble telescope reveal eight new Einstein rings, joining only three others previously known. Einstein rings are pairs of galaxies, with a foreground galaxy bending the light of a ... > more -
Astronomers And Computer Scientists Reveal Astronomical Events In Real Time
Astronomers have added an application to Google Earth that allows users to not only look at detailed pictures of the night sky at their convenience, but to observe unfolding cosmic events in real ... > more -
Astronomers Look At Ultraviolet Light To Find Star’s Tail
Astronomers found a tail of carbon, oxygen, and other material trailing behind a dying star called Mira. People have watched the star break down for 400 years, but only recently have astronomers ... > more -
Physicists Spot Interstellar Shock Wave Using Spitzer Telescope
The spirals of a "space tornado" may be the first step in the formation of a new star. The structure, observed with NASA's Spitzer infrared telescope, is a shock wave created by a jet of material ... > more -
Space Physicists and Atmospheric Scientists Can Now Predict Disruptions Caused by the Sun's Coronal Mass Ejections
Solar activity can wreak havoc in communications systems -- particularly during coronal mass ejections, when plumes of electrically charged particles hit earth's atmosphere. Scientists can now track ... > more -
With Precautions, Anyone Can Observe the Sun Safely
Sun spots are cooler regions on the sun's surface held up by magnetic fields, and they can have dramatic effects on space weather, disrupting satellite communications. Astrophysicists track them with ... > more
