Is the Star Manual of Master Shi the oldest known astronomical catalog? Experts are divided.

The National Science Foundation's Dark Energy Camera reveals a stunning glimpse into the 'dark nebula' known as the Circinus West molecular cloud, a region of space that's so dense with gas that light can't escape it.

Researchers conducted the first-ever near-infrared analysis of an extragalactic recurrent nova and found it is one of the hottest nova explosions ever discovered.

Scientists thought they saw a distant star swallow a planet for the first time ever. But new observations from the James Webb Space Telescope suggest something very different, but equally rare, may have happened instead.

After 11 years mapping the Milky Way, the European Space Agency's Gaia space telescope has retired. Scientists hailed it as "the discovery machine of the decade."

SPHEREx's first images — containing roughly 100,000 points of light stars, galaxies and nebulae — have confirmed that the telescope is working according to its design.

You can tell spring has officially begun in the Northern Hemisphere just by looking at the stars. Here's how to easily spot the Spring Triangle without a telescope.
