June 23, 2011- Using the VISIR instrument on ESO’s Very Large Telescope (VLT), astronomers have imaged a complex and bright nebula around the supergiant star Betelgeuse in greater detail than ever before.
This structure, which resembles flames emanating from the star, is formed as the behemoth sheds its material into space. Betelgeuse, a red supergiant in the constellation of Orion, is one of the brightest stars in the night sky.
It is also one of the biggest, being almost the size of the orbit of Jupiter — about four and half times the diameter of the Earth’s orbit.
