This NASA/ESA/CSA James Webb Space Telescope Picture of the Month brings us a scene from the distant universe. Pictured here is the galaxy cluster MACS J1149.5+2223, or MACS J1149 for short, which is ...

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 ...

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

The rapid expansion of the universe has been the most perplexing enigma in physics. To unravel this cosmic puzzle, scientists turn to the fundamental laws of physics, including Albert Einstein's ...

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

Anyone who has ever measured something twice, like the width of a doorway, and gotten two different answers knows how annoying it can be. Now imagine you're a physicist, and what you're measuring ...

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, ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Gravitational lensing occurs when things with mass create ripples ...

A new image from the Hubble Space Telescope reveals the funny things that galaxies can achieve when they huddle together. When galaxies are far enough away, the 33-year old observatory gets a sort of ...

“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 ...

The European Space Agency's Euclid mission released a "quick data release" encompassing three deep-field mosaics totaling 63 square degrees, representing the largest contiguous area observed by an ...

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 ...
