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.
WR 25 and Tr16-244, at the bottom of the image, are located within the open cluster Trumpler 16. This cluster is embedded within the Carina Nebula, an immense cauldron of gas and dust that lies approximately 7500 light-years from Earth in the constellation of Carina, the Keel
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.
