Active Galactic Nuclei (AGN) are galaxies with a rapidly growing supermassive black hole (SMBH) at their centre. A recent study, using both ground and space observations, suggests that many of the brightest SMBHs may be escaping our detection due to their heavily obscured environments. This draws a completely different picture compared to our current understanding of luminous AGN.
Astronomers detected two supermassive black holes (SMBHs) orbiting each other, within a giant elliptical galaxies. The SMBHs are 24 light years apart and have a combined mass of about 15 billion times the mass of our Sun. It takes them about 30,000 years to complete a single orbit
Gamma-ray Bursts (GRBs) are the most violent explosions in the universe after the Big Bang. Recently a team of astrophysicists tried to answer what causes the wide range of their spatial offset from their host galaxies.

Supermassive black holes exist in the centre of most, if not all, galaxies. An open question in astrophysics, however, is how these enormous black holes, that weigh billion times the mass of the sun, existed in the early universe.
Juno is a NASA spacecraft orbiting the planet Jupiter. It was launched on 5th of August 2011 and entered a polar orbit of Jupiter on the 5th of July 2016. Juno is the second spacecraft to orbit Jupiter, after the Read More …
