Description
English: In January 2002, a dull star in an obscure constellation suddenly became 600,000 times more luminous than our Sun, temporarily making it the brightest star in our Milky Way galaxy. The mysterious star, called V838 Monocerotis, has long since faded back to obscurity. But observations by NASA's Hubble Space Telescope of a phenomenon called a "light echo" around the star have uncovered remarkable new features. These details promise to provide astronomers with a CAT-scan-like probe of the three-dimensional structure of shells of dust surrounding an aging star.
Français : Echo lumineux. Courant janvier 2002 l'etoile V838 de la Licorne (en rouge, au centre) devient brusquement 60 000 fois plus brillante que le soleil, ce qui fit temporairement d'elle l'etoile la plus brillante de notre voie lactee. Dans les mois suivant ce flash cosmique, Un phenomene d'"echo lumineux" observable sous la forme d'aneaux concentriques autour de l'etoile. Ce phenomene permet d'etudier la structure des nuages de poussiere entourant cette etoile en fin de vie.
