A Gravitational Lens. Galaxies in this James Webb Space Telescope image appear to be stretched into arcs and lines, their ...

Gravitational lenses, which are massive galaxies or galaxy clusters that act as a magnifying glass by bending light passing them, are one of the Universe's golden gifts to astronomers. To help unlock ...

In just a decade, gravitational wave observatories have changed astronomy. In this short time, we have accumulated hundreds ...

A gravitational lens is formed when one galaxy is hidden behind another—at least, from our perspective—yet it’s possible to still see the hidden galaxy poking out around the edges of the one in front.

For much of the twentieth century, scientists expected the expanding universe to slow over time. The opposite turned out to ...

Around 37,000 citizen scientists combed through 430,000 images to help an international team of researchers to discover 29 new gravitational lens candidates through Space Warps, an online ...

With the help of artificial intelligence, astronomers discovered 56 new gravity lens candidates. This picture shows a sample of the handmade photos of gravitational lenses that the astronomers used to ...

Pictures of gravitational lenses from the AGEL survey. The pictures are centred on the foreground galaxy and include the object name. These new gravitational lenses were found by a machine learning ...

GAL-CLUS-022058s is one of the largest and most complete Einstein rings ever discovered. This beautiful gravitational lens is created by a bright, distant galaxy which happens to be aligned directly ...

There are roughly 100 billion galaxies in our universe, and it would take many lifetimes for humans to look at them all. Even if our scientists only focused on a tiny sliver of the night sky, there's ...

Clumps and clusters of galaxies exhibit gravitational effects on the light-and-matter behind them due to the effects of weak gravitational lensing. In addition, arcs, multiple images of the same ...

This NASA/ESA Hubble Space Telescope image offers us the chance to see a distant galaxy now some 19.5 billion light-years from Earth (but appearing as it did around 11 billion years ago, when the ...
