Rare relic is one of only three fossil clouds known in the universe. A relic cloud of gas, orphaned after the Big Bang, has been discovered in the distant universe by astronomers using the world’s most powerful optical telescope, the W. M. Keck Observatory on Maunakea, Hawaii.

The discovery of such a rare fossil, led by PhD student Fred Robert and Professor Michael Murphy at Swinburne University of Technology, offers new information about how the first galaxies in the universe formed...

New NASA research confirms that Saturn is losing its iconic rings at the maximum rate estimated from Voyager 1 & 2 observations made decades ago. The rings are being pulled into Saturn by gravity as a dusty rain of ice particles under the influence of Saturn’s magnetic field.

“We estimate that this ‘ring rain’ drains an amount of water products that could fill an Olympic-sized swimming pool from Saturn’s rings in half an hour,” said James O’Donoghue of NASA’s Goddard Space Flight Center in Greenbelt, Maryland...

Astronomers have captured one of the most detailed views of a young star taken to date, and revealed an unexpected companion in orbit around it. While observing the young star, astronomers led by Dr John Ilee from the University of Leeds discovered it was not in fact one star, but two.

The main object, referred to as MM 1a, is a young massive star surrounded by a rotating disc of gas and dust that was the focus of the scientists’ original investigation. A faint object, MM 1b, was detected just beyond the disc in orbit around MM 1a...

New way to explain how a black hole’s plasma jets boost particles to the highest energies observed in the universe. Magnetic field lines tangled like spaghetti in a bowl might be behind the most powerful particle accelerators in the universe...
