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

Einstein Rings
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 background

Space Tornado
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 slamming on a

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

Astrophysicists Discover New Details of How Stars Collapse
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 and ... > 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 -
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 -
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 -
Planetary Scientists To Find Out Composition, Structure Of Asteroids
A NASA mission to two asteroids, one formed of lava and the other potentially containing water, will help find clues about the formation of our solar ... > 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 -
Microbiologists and Astrobiologists Help Kids Discover New Species
Extremophiles are microbes that have adapted to extreme environments, such as Utah's Great Salt Lake. But new microorganisms can be found in everyday places, and scientists are showing school kids ... > more -
Acoustic Waves Could Help Put Out Flames in Zero-Gravity Environments
Aboard NASA's "Weightless Wonder" airplane, physicists are experimenting with combustion and fluid flows in zero-g and developing a fire extinguishing system based on sound waves. The technique could ... > more
