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.

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

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

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

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 -
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 -
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 -
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 Use Hubble to Spot Oxygen-Rich Soil on Moon
The Moon's surface is covered with oxygen-rich soils, Hubble Space Telescope images show. Planetary scientists believe the oxygen could be tapped to power rockets and be a source of oxygen to breathe ... > 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 -
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 -
Astronomers Spy Earth-like Planet Forming Around Distant Star
Astrophysicists analyzing infrared images captured by the Spitzer Space Telescope found indications of a dust cloud surrounding a relatively young star. The star is 10 to 16 million years old, and ... > more -
Astronomy Students Find 1,300 New Asteroids
Astronomy students looking for supernovae examined photographs and found asteroids. They used both unaided eyes and computer analysis to identify the asteroids. The images were composited from three ... > more
