In this new Hubble image two objects are clearly visible, shining brightly. When they were first discovered in 1979, they were thought to be separate objects - however, astronomers soon realised that these twins are a little too identical! They are close together, lie at the same distance from us, and have surprisingly similar properties.
If placed in the middle of our solar system, the star VY Canis Majoris would engulf all the planets out to Saturn's orbit. This monster, appropriately called a red hypergiant, is as bright as 300,000 Suns
An international team of astronomers used the Hubble Space Telescope to help make a precise measurement of the mass of a planet outside our solar system. The Hubble results show that the planet is 1.89 to 2.4 times as massive as Jupiter, our solar system's largest orbiting body
This new NASA/ESA Hubble Space Telescope image shows ghostly green filaments, lying within galaxy Mrk 1498. This filament was illuminated by a blast of radiation from a quasar - a very luminous and compact region that surrounds the supermassive black hole at the centre of its host galaxy.Its bright green hue is a result of ionised oxygen, which glows brightly at green wavelengths.
