How can you fairly compare one telescope to another? It's all in the (angular) resolution. The entire point of introducing telescopes into astronomy is to make distant things more visible.

Just how powerful is the world's most powerful telescope? Let's start with the human eye. The human eye has an angular resolution of about 1 arcminute. That's pretty impressive. Take a circle ...

Abstract: We have analysed short-exposure high-resolution images obtained on the William Herschel Telescope (WHT), Big Telescope Azimuthal (BTA) and Canada–France–Hawaii Telescope (CFHT) in order to ...

Using new observations with the ALMA telescope array in Chile, researchers have compiled the most precise map of three regions in the Milky Way's Central Molecular Zone to date, providing valuable ...

To mark the 35th anniversary of the Hubble Space Telescope, Space.com looks at some of the most scientifically significant images that have emerged from the observatory's lens.

Its angular resolution goes all the way down to 10 to the minus 10 arcseconds. That is 1 million times better than the Event Horizon Telescope. And because of the effects of gravitational lensing ...

Jackie explains that a laser inside the tubes is split, bounces off mirrors, and goes straight back to sensors at the center ...

Lu Lu looks forward to the next two decades of neutrino astrophysics, exploring the remarkable detector concepts needed to ...

Structures known as "zippers" and "twisters" in the early universe may explain why dwarf galaxies tend to line up with each ...

Artists and scientists have been creating optical illusions for centuries. Here are 35 mind-bending examples that prove you ...

GUIYANG - Chinese scientists are considering setting up smaller radio telescopes surrounding FAST to increase array resolution, authorities said. According to the FAST observation station with the ...
