Planets usually stay close to their host stars, tracing steady paths shaped by gravity. Yet some planets break free and drift ...

Astronomers used gravitational lensing to detect a supernova 10 billion light-years away, providing spatially separated images that help study cosmic expansion and early Universe events.

Decades after it became clear that the visible Universe is built on a framework of dark matter, we still don’t know what dark matter actually is. On large scales, a variety of evidence points toward ...

In the center of this image, taken with the NASA/ESA Hubble Space Telescope, is the galaxy cluster SDSS J1038+4849 and it seems to be smiling You can make out its two orange eyes and white button nose ...

Let's turn the sun into a telescope. In fact, we don't have to do any work—we just have to be in the right spot. But how can the sun be a telescope? The sun is not a mirror, but it is a lens. And we ...
