A burst of radiation from a star 20 light-years away from Earth, in the constellation Unicorn, allowed the Hubble Space Telescope to observe a rare sight of interstellar matter
An eruption of radiation from a star located 20 thousand light years from Earth, in the constellation Unicorn, allowed the Hubble Space Telescope to observe a rare sight of the interstellar material - the gas and dust that fills space. The light emitted from the star V838 Monosrotis hit the outer shell of the star and was reflected back from it, a phenomenon known as "echo". When the light was emitted, the brightness of the star was 600 thousand times that of the Sun.
The burst of radiation was first observed on May 20, 2002. The gaps in the mantle are areas where there is a small amount of dust.
