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.
