A cluster of young stars at the heart of the “smiling cat” nebula generates torrents of radiation that ionise surrounding gas, creating a vast reddish-orange nebula.
Discovered in 1779, M61 serves as a brilliant subject for ground- and space-based telescopes alike, with spiral arms bursting with young stars and a luminous core harboring a supermassive black hole.
ESO’s Very Large Telescope captures a colourful view of an unusual bipolar planetary nebula resembling a vast butterfly stretching up to four light years across in the southern constellation Vela.
After decades of observation, researchers confirm the orbit of a star in close orbit around the Milky Way’s central black hole obeys Einstein’s predictions.
A deep infrared view of the Orion Nebula reveals an abundance of faint brown dwarfs and an unexpected number of planetary-mass objects, key elements in studies of star formation and the environments that produce them.
Putting general relativity to the test, astronomers compared the known gravity of a galaxy with the bending of spacetime needed to produce a spectacular ‘Einstein ring’ and found, once again, that Einstein was correct.
Astronomers using ESO’s Very Large Telescope have for the first time directly observed granulation patterns on the surface of a star outside the Solar System — the ageing red giant π1 Gruis.
A new planet-seeking instrument installed on the European Southern Observatory’s Very Large Telescope in Chile has made its first observations, beginning a search for exoplanets with unprecedented precision by looking at the minuscule changes in the light of their host stars.
