ASTRONOMERS LOCATE MILKY WAY'S BLACK HOLE

Astronomers using the giant Keck observatory in Hawaii have pinpointed an immense black hole at the centre of the Milky Way. With the mass of over 2 million suns, this black hole causes nearby stars to speed up as they revolve around the galactic core. By triangulating the effect of the hole, they were able to located its exact position, at a point known as Sagittarius A.

HUBBLE TIMELAPSE SHOWS DYNAMIC BINARY SYSTEM

Thanks to Hubble's lengthy tour of service, Astronomers have been able to go back and take another look at objects they imaged several years ago. Many of these objects are changing quite dramatically. For example, the binary system XZ Tauri is in the process of ejecting an enormous bubble of hot gas 96 billion kilometres into space. Watching this event unfold over the last 5 years has given Astronomers valuable insights into the formation of these young star systems.

MIR STILL IN FINANCIAL DISTRESS

Even though it's been in the news regularly with all kinds of new entrepreneurial ventures, Mir's future is uncertain. The Russian spacestation is still in constant danger of running out of funding, forcing it to be deorbited. Despite the $20 million paid by businessman Dennis Tito for a flight to the station, as well as an additional $20 million when NBC pays for Destination Mir, the station is constantly strapped for cash, and the Russian parliament is considering a plan to deorbit the station safely.

WEATHER satellite LAUNCHES

After yesterday's delay, the Titan 2 carrying the NOAA-L weather satellite launched into orbit this morning without a hitch. The converted ICBM lifted off from the Space Launch Center 4 at Vandenberg Air Force Base in California 10:22am GMT. The satellite separated from the booster almost 7 minutes later, at an altitude of 870 kilometres. The NOAA-L satellite will provide global weather data for use on short and long-term forecasts and climate models.
