aurora

Giant shock waves emanating from the Sun can give us some breathtaking auroras here on Earth. They can also cause energy surges that can damage our infrastructure, says a new study that looks at how their angles of impact shape their consequences.

If you’re planning to see the aurora soon, keep an eye out for a brand new type of sky glow that’s just been discovered. This short-lived phenomenon only appears after midnight and seems to be the inverse of something just spotted a few years ago.

While millions of people who couldn't normally see the aurora took in the recent color-filled spectacle in the night sky, NASA's Solar Dynamics Observatory was looking straight at the sun to catch the action. The fiery footage is well worth a watch.

The annual Astronomy Photographer of the Year competition highlights the beauty of the night sky. The shortlist for 2023 has now been published, starring some stunning shots of the Sun, our majestic Milky Way, and awe-inspiring aurorae.

NASA has announced the selection of five Medium Class Explorer concept mission proposals that could one day revolutionize our understanding of the space environment, and see pictures taken of the Sun's polar regions.

Some spectacularly lucky timing helped a number of amateur photographers in Southwest Finland capture a new and very rare form of the Northern Lights that doesn't fit into any pre-existing categories. They're calling them "dunes."

A brown dwarf was recently downgraded to planet status (albeit a huge one), and now astronomers have discovered that it generates an enormous magnetic field, which could provide a new tool in the search for exoplanets.

​NASA has released a stunning time-lapse video of Earth as seen in 4K quality from the International Space Station.
