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! **

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.
