Weather on other planets and moons can be much more extreme than on Earth.
The interaction of solar winds and the Earth’s atmosphere produces the northern lights that dance across the night sky.
It has only been in the past century that weather prediction on Earth has advanced enough to work two weeks in advance. Predicting space weather, however, is only reliable an hour in advance.
Proxima Centauri is the closest star to the solar system and is home to a potentially habitable planet.

Astronomers just measured the largest flare ever from Proxima Centauri, humanity's closest neighboring star. These flares could be bad news for life trying to develop on a planet orbiting the star.
April 26 is the first supermoon of the year.
April’s super full moon was known as the pink moon because it heralds the arrival of spring flowers.

Sea level is still rising, and when that lunar cycle starts upward again, it will mean double trouble for places like Miami.
Astronomy has been hailed as one area of science making moves to promote gender equity. But new modelling suggests targets are still not being met, and more effort is needed to nurture womens' careers.
Uncle Segar is an expert on many things including the land, sea and sky. This knowledge is then captured in his artworks.
A planet in a triple-star system has been discovered.
Publicly available data and collaborations between scientists have led to the discovery of a planet in a triple-star system.

The black hole is part of a binary star system within our Milky Way galaxy. It orbits a colossal supergiant companion star.
The red planet.
There are some great opportunities to see the planet travelling across the night skies.

A small add-on to existing gravitational wave detectors could reveal what happens to matter as it becomes a black hole, a process like the big bang in reverse.
Australian astronomers are part of a prize-winning team that was the first to pinpoint the location of a fast radio burst. But there is much we still don't know about these mysterious bursts.
Dark matter can be inferred from an assortment of physical clues in the universe.
Researchers have found a way to speed up the search for dark matter using technology from quantum computing. By squeezing quantum noise, detectors can now look for axions twice as fast.

If you are a sci-fi junkie you've probably wondered what would happen if you were unlucky enough to fall into a black hole. How well you'd fare all depends on the type of black hole.
MeerKAT Radio Telescope.
Radio galaxies may be the oldest galaxy systems, providing clues to the evolution of galaxies.
The two giant radio galaxies found with the MeerKAT telescope. In the background is the sky as seen in optical light. Overlaid in red is the radio light from the enormous radio galaxies, as seen by MeerKAT.

Based on what we currently know about the density of giant radio galaxies in the sky, the probability of finding two of them in this region is extremely small.
Elliptical galaxies are filled with extremely old stars.
These results might lead us to revise our understanding of how galaxies stop forming their stars.
The Southern African Large Telescope has been a key part of South Africa’s astronomical contributions.
Cape astronomers were responsible for, among other things, the first measurement of the distance to a star; the first photographic sky survey and the accurate measurement of the distance to the sun.
A poor start for meteor showers in 2021 but things get better with a possible spectacular surprise later in the year. Here's your guide on when and where to look to catch nature's fireworks.
