A US-led coalition and China are both planning to establish bases on the Moon. How the two nations will navigate actions on the Moon and how other countries will be involved is still unclear.
Tens of thousands of satellites orbiting Earth will hamper astronomers’ efforts to study the Universe and spot dangerous asteroids, as well as brightening the sky and hiding stars from the rest of us.
Beyond just looking at black holes, the next-generation Event Horizon Telescope collaboration is the first to bring together perspectives from across the sciences and humanities.
Astronomers have long known where water is first formed in the universe and how it ends up on planets, asteroids and comets. A recent discovery has finally answered what happens in between.
The newly discovered comet C/2023 A3 Tsuchinshan-ATLAS is anticipated to be spectacularly bright late next year. But it’s important to temper our expectations.
With more than 5,000 known exoplanets, astronomers are shifting their focus from discovering additional distant worlds to identifying which are good candidates for further study.
Many telescopes use the radio spectrum to learn about the cosmos. Just as human development leads to more light pollution, increasing numbers of satellites are leading to more radio interference.
With more than 100 lunar missions planned in coming years, space junk near the Moon could become an issue for humanity. No agency tracks lunar space junk, so two astronomers decided to do it themselves.
While we can’t see inside a black hole, we can spot the intensely bright glowing disc that surrounds one. Now, we might better understand why these discs appear to ‘twinkle’.
Skies in the Northern Hemisphere have been graced by a rare, green comet. Now, it’s our turn to look for it in Australia – but the view will be dimming rapidly.
