When it comes to commercial space tourism, suborbital flight are the first frontier. But what are the risks? Are there health requirements? What should you know before taking such a way-out trip?
The primary objective of CHEOPS is to better understand the planets that we’ve already found. And its mission is now in full swing.
Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.
Researchers have made some of the most accurate clocks imaginable in recent years, but the trick is harnessing those clocks to electronics. Using lasers to tune microwaves bridges the gap.
When the outlook is dark, astronomy can help us take the long view and build for the future.
SpaceX recently launched 60 satellites into orbit around Earth as part of its Starlink programme.
Like a cosmic butterfly in the sky, radio galaxy PKS 2014-55 was observed by CSIRO researchers with the Australian SKA Pathfinder telescope.
It is a pretty spectacular achievement to not only rendezvous with an asteroid as it is whizzing around the Sun but also collect a sample. Here's what the researchers learned.
The term 'Big Bang' might make you think of a massive explosion. Put the thought out of your head. Rather than an explosion, it was the start of everything in the universe.
From the Moon's size to the first calculator, the ancients made some jawdropping discoveries without modern technology.
Thirty years ago the Hubble Space Telescope began snapping photos of distant stars, providing a time machine that has taken astronomers back to when the universe was less than a billion years old.
We asked astronomers: are we alone in the Universe? The answer was surprisingly consistent.

'I think that we will discover life outside of Earth in my lifetime. If not that, then in your lifetime,' one astronomer told us.
Leap years were devised in Julius Caesar's time, to fix the pesky problem that Earth's year isn't exactly 365 days. But 15 centuries later, our calendars were still slightly askew.

Today on the podcast, we explore what we know about dark energy, believed to be responsible for the acceleration of the expansion of the Universe.
The Earth's shadow does not cause the Moon's phases.
We're not sure how the rings work or how they formed, but there are a few theories.
This observation means astronomers can now develop and test theories that explain how high-mass stars gain their mass.
Astronomy and astrology do not agree on the dates of the zodiac constellations.
Why isn't there an endless variety of planets in the universe? An astrophysicist explains why planets only come in two flavors.
An upgrade for the Australia Telescope Compact Array will enable major new discoveries about the universe
