Multiverse more hospitable than previously thought?

18 May 2018 Astronomy Now

A new computer analysis suggests much higher levels of dark energy would not, as many believe, prevent the formation of stars and planets, implying life might be more common across the Multiverse – assuming it exists – than previously believed.

Star formation underway 250 million years after Big Bang

17 May 2018 Astronomy Now

Astronomers using ESO’s Very Large Telescope and the Atacama Large Millimetre/submillimetre Array have observed a galaxy 13.3 billion light years away that includes stars that must have been shining just 250 million years after the Big Bang.

More evidence for water vapour jetting from icy Europa

16 May 2018 Astronomy Now

Data collected by the Galileo spacecraft during a 1997 flyby of Jupiter’s moon Europa indicate the probe likely flew through a plume of water vapor, the latest evidence the icy moon likely harbours a vast sub-surface ocean beneath its frozen crust.

‘Monster’ black hole consuming the Sun’s mass every two days

15 May 2018 Astronomy Now

Australian astronomers have found one of the fastest-growing super-massive black holes in the known universe, a monster 20-billion-solar-mass quasi-stellar object consuming the equivalent of the Sun’s mass every two days.

Space station instrument fills in blanks about binary pulsar

14 May 2018 Astronomy Now

An instrument aboard the International Space Station has detected a binary star system made up of a fast-spinning pulsar and a compact white dwarf that orbit each other every 38 minutes, a record for an accreting millisecond X-ray pulsar.

Astronomers chance upon mysterious binary companion

13 May 2018 Astronomy Now

Astronomers studying a binary star system in a thick disk of dust chanced upon a large exoplanet – or a small brown dwarf – orbiting at an enormous distance from the parent suns, apparently embedded in its own dust disk.

‘Exiled’ carbon-rich asteroid found in distant Kuiper Belt

12 May 2018 Astronomy Now

Astronomers using ESO’s Very Large Telescope have discovered the first carbon-rich asteroid in the distant Kuiper Belt. The asteroid likely originated in the inner Solar System and was ejected by gravitational encounters with the Sun’s gas giants.

NASA approves helicopter to launch with 2020 Mars rover

11 May 2018 Astronomy Now

NASA is adding a small helicopter to the agency’s Mars 2020 rover that will become the first heavier-than-air vehicle to fly on another planet. The technology demonstrator features twin counter-rotating blades.

Stellar mass black holes swarm in Milky Way’s core

11 May 2018 Astronomy Now

The Chandra X-ray Observatory has detected a dozen X-ray binaries containing stellar-mass black holes near the core of the Milky Way. Theoretical analysis indicates thousand more likely are lurking unseen.
