SCIENTISTS DISCOVER MEDIUM-SIZED BLACK HOLES
Astronomers have discovered several examples of medium-sized
black holes located in nearby Galaxies - probably between 10
and 100,000 times the mass of our Sun - possibly caused by the
aggregation of many smaller black holes.
ANOTHER POSSIBILITY FOR UNIVERSE'S MISSING MASS
Still on the hunt to find the universe's missing mass, Astronomers
have used the NASA Extreme Ultraviolet Explorer peek into the hidden
hearts of of distant Galaxy clusters. They've found huge clouds of
hot gas sucked into the center of these clusters - sometimes causing
gravitational collapse of the whole cluster.
EUROPEAN EUTELSAT LAUNCHES
Carried aboard a Lockheed Martin Atlas 2AS rocket, the Eutelsat W3
satellite was placed into geostationary orbit Monday night. The
launch was a complete success, a relief considering the rash of
recent launch accidents.
CONTROVERSIAL PAPER WARNS OF POSSIBLE asteroid IMPACT
Newly discovered asteroid 1999 AN10 has caused quite a stir in the
astronomy community, as a recent paper warns that it could strike
the Earth in 2039. Although the rock crosses the Earth's path twice
a year, gravitational effects could push it into a collision
course... or not, depending on who you ask.
