Quasi-Stellar Radio Source - Basic Information About Quasars
A Quasar is an enormously bright object at the edge of our
universe with the appearance of a star when viewed through a
telescope. It emits massive amounts of energy, more energy
than 100 normal galaxies combined. The name comes from a
shortening of quasi-stellar radio source (QSR). Current
theories hold that quasars are one type of active galactic
nuclei (AGN). Many astronomers believe supermassive black
holes may lie at the center of these galaxies and power
their explosive energy output.
Neighbor - Newly-Discovered Star May Be Third-Closest
The local celestial neighborhood just got more crowded with
a discovery of a star that may be the third closest to the
Sun. The star, "SO25300.5 165258," is a faint red dwarf star
estimated to be about 7.8 light-years from Earth in the
direction of the constellation Aries.
Holes - The Inescapable Truth About Black Holes.
Scientists believe black holes are the end product in
the lifecycle of giant stars. If a star is 3 or 4 times
as massive as our own sun, even after it has exhausted
all its fuel, it can collapse under its own gravity.
Just like a crab burying itself at the beach and pulling
the sand down over itself, the collapsing star pulls in
everything around it as well. Discover information and
Black Holes Shed Light on Galaxy
Astronomers are concluding that monstrous black holes
weren't simply born big but instead grew on a measured
diet of gas and stars controlled by their host galaxies
in the early formative years of the universe. Find more
black holes information and pictures of black holes.
Top 10 Things
You Should Know About Venus - Solar System Facts
Venus whose Greek equivalent was Aphrodite was the Roman
goddess of love and beauty. Venus probably got its name from
being the brightest object in the sky except for the Sun and
the Moon. Venus has always been considered a feminine
planet, with many legends and stories concerning its
inhabitants. Even one modern doctor says that women are from

Solar System Facts
Named after the Roman god of commerce, travel and thievery,
Mercury is the second smallest planet in the solar system,
larger only than Pluto, the most distant planet in our solar
system. If Earth were the size of a baseball, Mercury would
be the size of a golf ball. Viewed from Mercury, the Sun
would look almost three times as large as it does from

Things You Should Know About the Sun
Our Sun has inspired mythology in almost all cultures,
including ancient Egyptians, Aztecs, Native Americans, and
Chinese. Our Sun is actually the closest star to Earth. The
Sun is a massive shining sphere of hot gas. The connection
and interaction between the Sun and the Earth drive the
seasons, currents in the ocean, weather, and climate.
Information and Pictures
Throughout history, people have been awed and alarmed by
comets, stars with "long hair" that appeared in the sky
unannounced and unpredictably. We now know more about
comets. We can predict the orbits of many of them, but not
all. Discover comets facts and pictures.
