The reaction has been swift since a high-profile astronomer’s legacy of sexual harassment against his students was exposed.
Supermassive black holes, containing as much mass as millions or billions of suns, exist at the centre of all galaxies, including our own Milky Way.

Tanya Hill speaks with Meg Urry about distant galaxies and the supermassive black holes that lurk in their centres.
Unlike science fiction films featuring grotesque aliens and faraway galaxies, Ridley Scott’s The Martian depicts a sci-fi space mission that could soon be science fact.

NASA has set a target date of 2030 for a manned mission to Mars. With no real scientific breakthroughs needed, success depends on developing the proper technology.
A rare super blood moon visible from parts of the Earth this month will delight those people lucky enough to see it. But why has this marvel of the solar system got some people so worried?

Geomagnetic storms can interact with particles near Earth, causing issues for satellites and other tech. Researchers send balloons 20 miles into the sky to figure out just what’s going on up there.
They’re are the overachievers of the universe: incredibly dense but very small when compared to others stars. So how much do we know about the extreme behaviour of neutron stars?
Australian astronomers have their eyes on the skies.

Kepler-452b’s discovery last week has raised the perennial question: are we alone in the universe? While the find’s scientific import is huge, it also poses questions that go to the heart of religion.
What kind of creatures might we find populating the cosmos?

In the long lead-up to our ultimate flyby of Pluto, space science has reconfigured our notions of what it means to be a solar system, a planet, a world.
Breaking down the colours in the star light can reveal more about what you are looking at.

The existence of a “Planet X” in the outer solar system was the subject of great speculation, and was finally settled with the discovery of Pluto in 1930.
Music and astronomy have been intimately linked since antiquity.

From Twinkle Twinkle to Space Odyssey and beyond, humans have always turned to music to help deal with the profoundly confronting enormity of the cosmos. Is that a match made in the heavens?
What can what’s on the moon tell us about our home planet?

The moon might harbor bits of the Earth that blasted off our planet billions of years ago. These lunar time capsules could hold secrets about conditions here at home back when life was first emerging.
This amazing photo even shows the four Galilean moons around Jupiter: Io, Europa, Ganymede, and Callisto.

Look up tonight and you’ll see a stunning conjunction of the two brightest planets in the night sky.
Understanding how galaxies are arranged could be the key to figuring what causes the expansion of the universe.

Some atomic ratio detective work on our solar system neighbors tells us a lot about their watery pasts. That Venus and Mars are mostly dry now could be a cautionary tale for us on the Blue Planet.
