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 ...

The Hubble Space Telescope is a constant source of beautiful pictures of the wonders of space, and this week’s Hubble image shows a wonderful example of a phenomenon called gravitational lensing, ...

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 ...

A mysterious striped signal from the Crab Pulsar may finally be explained by a delicate balance between plasma effects and ...

A new study revealed hundreds of new strong gravitational lensing candidates based on a deep dive into data. The study benefited from the winning machine-learning algorithm in an international science ...

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 ...

object like a bright quasar hidden behind it. But there has been a persistent mystery for over 20 years: Einstein’s general theory of relativity predicts there should be an odd number of images, yet ...

NSF–DOE Vera C. Rubin Observatory, funded by the US National Science Foundation and US Department of Energy's Office of Science, will add an unprecedented amount of cosmological data to the study of ...

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 ...

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 ...

Thanks to the presence of a natural "zoom lens" in space, University of Chicago scientists working with NASA's Hubble Space Telescope have obtained a uniquely close-up look at the brightest ...

Jim Bickford is leading the Thin Film Isotope Nuclear Engine Rocket (TFINER) project to develop a system for propelling a craft through space faster and farther than ever before. This technology has ...
