The red supergiant star Betelgeuse, in the constellation of Orion, has been undergoing unprecedented dimming. This image was taken in January using the European Southern Observatory's Very Large Telescope.
This new ALMA image shows the outcome of a stellar fight: a complex and stunning gas environment surrounding the binary star system HD101584.
NASA's Spitzer Space Telescope captured the Tarantula Nebula in two wavelengths of infrared light. The red represents hot gas, while the blue regions are interstellar dust.
A white dwarf, left, is pulling material off of a brown dwarf, right, about 3,000 light-years from Earth.
This image shows the orbits of the six G objects at the center of our galaxy, with the supermassive black hole indicated with a white cross. Stars, gas and dust are in the background.
After stars die, they expel their particles out into space, which form new stars in turn. In one case, stardust became embedded in a meteorite that fell to Earth. This illustration shows that stardust could flow from sources like the Egg Nebula to create the grains recovered from the meteorite, which landed in Australia.
