For much of the twentieth century, scientists expected the expanding universe to slow over time. The opposite turned out to be true. Space is stretching faster today than in the past, and the precise ...

Using a phenomenon known as gravitational lensing, it might be possible to use the sun as a gigantic telescope to peer deep into space. When you purchase through links on our site, we may earn an ...

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 ...

A group of astronomers have made history by capturing an image of a record number of stars from a time when the universe was half its age. The astronomers detected 44 stars in the "Dragon Arc" galaxy, ...

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.

“The cosmological principle is like an ultimate kind of statement of humility,” explains James Adam, astrophysicist at the University of the Western Cape, Cape Town, South Africa, and lead author of ...
