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'étoile V838 de la Licorne (en rouge, au centre) devint brusquement 60 000 fois plus brillante que le Soleil, ce qui fit d'elle l'étoile temporairement la plus brillante de notre Voie Lactée. Dans les mois suivant, ce flash cosmique, un phénomène d'"écho lumineux", devint observable sous la forme d'anneaux concentriques autour de l'étoile. Ce phénomène permet d'etudier la structure des nuages de poussière entourant cette étoile en fin de vie.

Português: Em janeiro de 2002, uma estrela sem graça em uma obscura constelação de repente tornou-se 600.000 vezes mais luminosa que o Sol, tornando-se temporariamente a estrela mais brilhante em nossa galáxia Via Láctea. A estrela misteriosa, chamada V838 Monocerotis, já há muito desapareceu de volta à obscuridade. Mas observações feitas pelo Telescópio Espacial Hubble, da NASA, de um fenômeno chamado "eco de luz" em torno da estrela revelou extraordinárias novas funcionalidades.Estes detalhes prometem fornecer aos astrônomos com uma sonda CAT-scan-like a sondagem das estruturas tridimensionais de conchas de poeira em torno de uma estrela em envelhecimento.
