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, ...

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 ...

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 ...

An example of a gravitational lens found in the DESI Legacy Surveys data. The two red streaks near the middle of DESI-010.8534-20.6214 are the gravitationally lensed arcs ("straight" arcs) -- highly ...

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 ...

Gravitational lenses are cosmic phenomena that radically distort light passing by, make objects behind the lens appear much brighter, and help astronomers see distant parts of the universe. And now we ...
