Herbig-Haro objects are some of the rarer sights in the night sky, taking the form of thin spindly jets of matter floating amongst the surrounding gas and stars.
This image shows a gas giant planet circling the two red dwarf stars in the system OGLE-2007-BLG-349, located 8 000 light-years away. The planet - with a mass similar to Saturn - orbits the two stars at a distance of roughly 480 million kilometres. The two red dwarf stars are a mere 11 million kilometres apart
The NASA/ESA Hubble Space Telescope has snapped a striking view of a multiple star system called XZ Tauri, its neighbour HL Tauri and several nearby young stellar objects. XZ Tauri is blowing a hot bubble of gas into the surrounding space, which is filled with bright and beautiful clumps that are emitting strong winds and jets
Injecting a swarm of nanoparticles into the blood of someone who has suffered a brain injury may one day help to limit the damage - if experimental results in mice can be translated to humans. In mice, these nanoparticles seemed to reduce dangerous swelling by distracting immune cells from rushing to an injured brain.
