There are technological ways to hide a planet from intergalactic detection – as well as ways to signal that we’re just sitting here, eager for contact.
Aboriginal people have been using the stars to help remember routes between distant locations, and these routes are still alive in our highway networks today.
Astronomers were looking forward to the first high-res X-ray spectra from space, and all they would tell us about the cosmos. But unknown disaster seems to have befallen the Japanese satellite.
Each fortnight I get the amazing opportunity to speak about my top stories in space on ABC Breakfast News TV but for those of you who hate early mornings I wanted to make sure you got to hear of these…
After last summer’s Pluto flyby, the New Horizons spacecraft started sending data back to Earth – at 2 kilobits per second. Here’s some of what scientists have learned so far from that rich, slow cache.
The universe looks very different with X-ray vision, revealing some of the most energetic interactions in our galaxy. Japan’s new Hitomi telescope will help us see these wonders.
As the list of known planets beyond our solar system grows, the search for their moons is intensifying. One reason: they might hold the key to finding life elsewhere in the universe.
It takes something as stupendous as the merger between two black holes to generate detectable gravitational waves. Here’s how such incredible cosmic objects form.
The search for new objects, including new planets, in our solar system has turned up some interesting finds. There have been a few failures over the years too.
The Murchison Widefield Array sits in remote Western Australia far from noisy civilisation so it can help us understand the universe by tuning into radio waves from the distant cosmos.
The public outing of a number of high profile scientists in sexual harassment cases shows the current system of protecting women isn’t working. But there is a solution.
Extragalactic astrophysicists want to know how and why galaxies stop forming stars, change their shape and fade away. With help from citizen scientists, they’re figuring it out.
