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

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

Unlocking The Mystery Of The Moon
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.

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 -
Total Lunar Eclipse Casts Eerie Red And Orange Glow
A total lunar eclipse was observed during the summer of 2007. A total lunar eclipse occurs when a full moon passes through the earth's shadow during its orbit. When the sun, Earth and moon are ... > 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
