For the first time, astronomers have used a new imaging method on a ground-based telescope to capture the most detailed look ever at the disk surrounding a distant star.

Uzbekistan’s medieval astronomer Ulugh Beg built the most advanced observatory of his time, charting the stars with uncanny precision long before Galileo.

To find out, astronomers look closely at these spinning discs.

For about a century, astronomers have known that the Milky Way's stars orbit its core, and Gaia has precisely tracked their speeds and trajectories.

In 2019 and 2020, Betelgeuse began to grow dimmer and dimmer in brightness, so much that astronomers called this event, the ‘Great Dimming.’
