Astronomers using the Hubble Space Telescope have captured the most-detailed view yet of a distant quasar “lensed” into five separate images. Multiple images of nearby galaxies appear as well. The ...

Due to the special gravitational lens effect where light is bent as it passes heavy objects, such as galaxy clusters, a group of physics students at the Niels Bohr Institute observed a quasar whose ...

An international team of astronomers has discovered a complex cosmic mirage in the southern constellation Crater (The Cup). This "gravitational lens" system consists of (at least) four images of the ...

APM 08279-5255 is a massive black hole (quasar) that contains about 140 trillion times the amount in all of Earth’s oceans ...

For the first time, astronomers have seen the image of a distant quasar split into multiple images by the effects of a cloud of ionized gas in our own Milky Way Galaxy. Such events were predicted as ...

Jan. 23 (UPI) --The Hubble constant is the rate at which the universe is expanding. Through the decades, astronomers have developed more reliable ways to estimate the value of the Hubble constant, but ...

A Japanese team of astronomers led by Toru Misawa from Shinshu University has used the Subaru Telescope to observe a distant gravitationally lensed quasar and probed an active galactic nucleus in its ...

A new array of radio telescopes has captured its first images, showing a huge jet blasting away from a galaxy with a powerful black hole at its heart. The images, taken by the e-Merlin telescope array ...

A team of astronomers have observed a distant gravitationally-lensed quasar (i.e., an Active Galactic Nucleus;) with the Subaru Telescope and concluded that the data indeed present a 3-D view of the ...

Using the ESO 3.6-m telescope at La Silla (Chile), an international team of astronomers 1 has discovered a complex cosmic mirage in the southern constellation Crater (The Cup). This "gravitational ...

Artist's Diagram of the refraction event (not drawn to scale), showing how radio waves from the distant quasar jet are bent by a gas cloud in our own Galaxy, creating multiple images seen with the ...
