Venus in a New Light

Scientists have captured the first X-ray view of Venus using NASA’s
Chandra X-ray Observatory. The observations provide new information
about the atmosphere of Venus and open a new window for examining
Earth’s sister planet.

The Terrible Twos: What Might Happen If Our Sun Had A Twin

How would our Sun behave differently if it had a closely orbiting twin?
While astronomers don’t know the exact answer, NASA’s Chandra X-ray
Observatory has observed an intriguing star system that is beginning to
provide important clues.

Planning Pays Off – Chandra Sails Through the Leonids Unharmed

At 6:45 a.m., the drivers of the two cars lined up at the security gate
to Chandra’s Operation Control Center (OCC) parking lot. The drivers
waved at each other. They and other members of the Flight Operations and
Science Operations teams arrived early on this Sunday morning to keep
watch during Chandra’s encounter with the 2001 Leonid event.

Operations CXO Status Report (Friday 11/23/01)

Last week the observing schedule was halted twice due to high radiation
associated with solar flare activity. The loads were halted on Nov 19 at
9:50pm EST through a ground command to execute the SI Safing SCS 107.
This ensured that the accumulated radiation dose for ACIS remained below
the allowed threshold.


** Concentrate on Chandra’s Memory Games! **

The classic game of matching pictures has been updated with some of the
most recent Chandra images (requires Java).

** Question of the Week **

What is the most distant object Chandra can see, and what type of object
is it?

** Did You Know? **

Stars, like people, are seldom found in isolation. More than 80% of all
stars are members of multiple star systems containing two or more stars.
Exactly how these systems are formed is not well understood. Some are
thought to form when a collapsing cloud of gas breaks apart into two or
more clouds which then become stars, or when one star captures another
as a result of a grazing collision, or by a close encounter with two or
more other stars.
