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 ...

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, ...

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 ...

Peering into deep space, NASA's James Webb Space Telescope has helped astronomers find places to study gravitational lensing, an effect in which massive objects such as galaxies warp space-time itself ...

By studying how light from eight distant quasars is gravitationally lensed as it propagates towards Earth, astronomers have ...

In an extraordinary testament to the predictive power of Einstein’s theory of general relativity, a star system has been discovered that demonstrates extreme gravitational lensing. This observation ...

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 ...

“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 ...
