SOHO's
Birthday Flare
In
celebration of the birthday of its most diligent watcher, the Sun
has let loose an unusual and quick-fire series of eruptions during
the past few days. Saturday (Dec. 2) will be the 5th anniversary
of SOHO's launch into
space, on 2 December 1995.

Hubble
Discovers Missing Pieces of Comet Linear
To
the surprise and delight of astronomers, the Hubble telescope discovered
a small armada of "mini-comets" left behind from what
some scientists had prematurely thought was a total disintegration
of the explosive Comet LINEAR. In one observation, Hubble's powerful
vision has settled the fate of the mysteriously vanished solid nucleus
of Comet LINEAR, which was reported "missing in action"
following its passage around the Sun on July 26. Though comets have
been known to break apart and vanish before, for the first time
astronomers are getting a close-up view of the dismantling of a
comet's nucleus due to warming by the Sun. The results support the
popular theory that comet nuclei are really made up of a cluster
of smaller icy bodies called "cometesimals."

The
Glowing Eye of NGC 6751
Astronomers
using NASA's Hubble Space Telescope have obtained images of the
strikingly unusual planetary nebula, NGC 6751. Glowing in the constellation
Aquila like a giant eye, the nebula is a cloud of gas ejected several
thousand years ago from the hot star visible in its center.
"Planetary
nebulae" are named after their round shapes as seen visually
in small telescopes, and have nothing else to do with planets. They
are shells of gas thrown off by stars of masses similar to that
of our own Sun, when the stars are nearing the ends of their lives.
The loss of the outer layers of the star into space exposes the
hot stellar core, whose strong ultraviolet radiation then causes
the ejected gas to fluoresce as the planetary nebula. Our own Sun
is predicted to eject its planetary nebula some 6 billion years
from now.

HUBBLE
FINDS YOUNG STARS IN COSMIC
DANCE
A
trio of newborn stars, 1,400 light-years away are taking part in
a complex dance, as revealed by recent NASA Hubble Space Telescope
(HST) observations. Two are now closely embracing each other, while
the third has parted from their company.
The
new HST images in infrared light, combined with ground-based radio
observations, reveal three young stars. These stars are located
near a huge torus, or donut, of gas and dust from which they formed.

Inside Mars Reveals Rapid Cooling and Buried Channels
Top Image: By combining highly accurate topographic maps with new
plots of the planets gravitational field, researchers have
developed a working draft of what the planets interior looks
like several kilometers below the surface. This map shows the "moho",
the area where the planets crust borders its mantle. For a
higher res image of this picture, named cutaway.tif go to:
http://www.gsfc.nasa.gov/ftp/newsmedia/mars/channels
Bottom
Image: Evidence suggests that rapid heat flow in the Northern Hemisphere
produced a wide lowland area, encouraging the formation of channels,
which could have sluiced water resources into a large basin, even
an early ocean. Shown in this image is one such channel, draining
from the giant Valles Marineris into the wide, flat area of the
north. For a high resolution image of this picture named
, please go to: http://www.gsfc.nasa.gov/ftp/newsmedia/mars/channels/

Previously
unseen details of a mysterious, complex structure within the Carina
Nebula (NGC 3372) are revealed by this image of the "Keyhole
Nebula," obtained with NASA's Hubble Space Telescope. The
picture is a montage assembled from four different April 1999 telescope
pointings with Hubble's Wide Field Planetary Camera 2, which used
six different color filters. (Details)

HETE
Burst Alert Network
One
of the key features of the HETE-2 satellite is its ability to calculate
precise localizations of GRBs on board within seconds of burst onset,
and then to transmit the burst localizations to the ground as soon
as they have been calculated. The HETE-2 satellite utilizes a low-rate
VHF transmitter to continuously broadcast the burst information;
on the ground, an array of listen-only secondary ground stations
receive the data and transmit them to the MIT Control Center. Once
received at MIT, burst information are immediately relayed to the
GRB Coordinate Distribution Network at the Goddard Space Flight
Center for distribution to interested ground observers. http://gcn.gsfc.nasa.gov/10 January 2000
