Comet C/2023 A3 (Tsuchinshan-ATLAS) is expected to be the brightest spectacle of 2024. Our charts will help you find it in the night sky.
The Hubble tension has been described as a “crisis” for cosmology. Can it be resolved?
A new series delves into the big questions surrounding the nature of our universe.
These small galaxies are either crammed with stars or they host gigantic black holes. The data astronomers have collected continues to puzzle them.
If a star gets too close to a black hole, it gets shredded and produces a complex ball of light. These videos are the first time this dramatic event has been simulated in detail.
What’s so special about a supermoon? Hardly anything. There are better things to observe in the night sky, according to a professional astronomer.
This small coastal town’s efforts to reclaim the night skies for people and nature is truly inspirational. Here’s how you can help reduce light pollution and claim your own Dark Sky Place title.
Light pollution is a relatively new problem. Simple solutions can fix it.
Most presolar grains were destroyed in the formation of the universe. But some survived on meteorites.
Analysis of two major cosmic blasts deepens the mystery of where the universe’s ‘heavy’ elements come from.
The Eta Aquariid meteor shower peaks each year in early May, but this year it should be particularly good, thanks to dark skies and extra activity.
If you look carefully at the night sky, you may spot this fuzzy visitor with the naked eye – but binoculars will help.
Where specialized algorithms fail to classify star-borne pulses, human volunteers with just a little training can step in.
Medieval scholars connected celestial events to changes that happened on the ground, such as the overthrow of the king.
Some ancient texts record what were likely dying stars, faintly visible from Earth. If close enough, these events can disturb telescopes and even damage the ozone layer.
There are several ways in which stars can destroy and swallow their own planets.
We may be able to find traces of dark matter star explosions.
Floating crystals can pause the stellar aging process, providing a final energy source to otherwise dead stars.
Astronomers have spotted a surprisingly diverse set of planet-forming disks.
