NASA Satellites Spot Young Star in Growth Spurt

An adolescentstar in the midst of a dramatic growth phase has been observed with the help oftwo NASA space telescopes.

The newfound
star, called Gaia 1

7bpi, was first spotted by the European Space Agency’s Gaia satellite, but NASA’s asteroid-hunting
Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) satellite
serendipitously observed the star’s brightening at the same time that Gaia did.
Additional searches in NEOWISE’s data archives and the archives of NASA’s
infrared-sensing Spitzer Space Telescope showed that these spacecraft had
detected the flare-up in infrared light more than one year earlier.
