NASA Telescopes Discover Strobe-Like Flashes in Young Stars
Washington DC (SPX) Feb 12, 2013
Two of NASA's great observatories, the Spitzer and Hubble space telescopes, have teamed up to uncover a mysterious infant star that behaves like a strobe light. Every 25.34 days, the object, designated LRLL 54361, unleashes a burst of light. Although a similar phenomenon has been observed in two other young stellar objects, this is the most powerful such beacon seen to date. The heart of the fireworks is hidden behind a dense disk and an envelope of dust. Astronomers propose the light flashe ... read more
