NASA's James Webb Space Telescope has captured a breathtaking view of Arp 220, an ultra-luminous infrared galaxy (ULIRG) located in the constellation of Serpens, 250 million light-years away from Earth. Arp 220 is actually the merger of two spiral galaxies that began colliding about 700 million years ago, sparking an intense burst of star formation.
Have you heard of LU Camelopardalis, QZ Serpentis, V1007 Herculis, and BK Lyncis? No, they re not members of a boy band in ancient Rome. They re Cataclysmic Variables, binary stars that are so close together one star draws material from its sibling

gigantic but among stars it s classified as a dwarf. astronomers classify stars based on the spectral characteristics of the light they emit. on a plot of their luminosity versus their color most stars appear in a continuous band known as the main sequence in the midst of it is our sun a fairly average star. the smallest stars are called red dwarfs. they use up their hydrogen so slowly that they re likely to continue burning for trillions of years our sun by contrast is expected to shine for just 12000000000 years. this nebula contains the heaviest star identified by astronomers to date researchers are mystified by how it could accumulate so much mass this
