Even star systems have identity crises.

According to data from observatories like @chandraxray, a double star system has been rapidly flipping between two alter egos: a low-mass X-ray binary and a millisecond pulsar. https://t.co/GFi3fI12dV https://t.co/IvwaIfIeIE

Our @NASASolarSystem Psyche mission, led by @ASU, will journey to a metallic asteroid orbiting the Sun between Mars and Jupiter. Dr. Tim McCoy from the mission science team explains what this "metal world" may reveal about our solar system's formation: https://t.co/ZtdK7U7CYh https://t.co/XnN8rtTRbD

LIVE: In a teleconference, scientists & researchers discuss investigations launching aboard @SpaceX's Dragon spacecraft on the next cargo mission to @Space_Station. Launch is targeted for 1:45am ET, March 2 from Cape Canaveral Air Force Station.
