Hubble captures forgotten globular cluster ESO 591-12 in rare detail ESO 591-12 sparkles with red and blue stars of varying ...

High-resolution imagery from NASA’s Hubble Space Telescope confirmed eight rings, and data from the W. M. Keck Observatory in Hawaii confirmed a ninth.

Hubble had been in space for less than two years when its Goddard High Resolution Spectrograph detected traces of boron in a not-too-distant star. At an estimated age of 14.5 billion years, the ...

Astronomers have achieved a first in exoplanet hunting by using the Hubble Space Telescope images to investigate a mysterious event that could reveal the existence of a “rogue planet” drifting through ...

"Thanks to the high resolution of our new images, we detected a faint structure on the northeast side of this supernova remnant that had not been observed before." The Hubble Space Telescope may ...

The light that the NASA/ESA Hubble Space Telescope collected to create this image reached the telescope after a journey of ...

"Although [DASH] doesn’t go as deep as something like the Ultra-Deep Field, it covers a lot of on-sky area, which is really important when you’re trying to find very rare things," says Cutler."DASH ...

Simon’s team used Hubble’s high-resolution images to take a detailed look at the size, shape and color changes of the Great Red Spot. “When we look closely, we see a lot of things are ...

Essentially a wide-angle version of Hubble (with the same sized mirror), Roman will capture the equivalent of at least 100 high-resolution Hubble images in a single exposure.

Webb has four times the resolution of the Hubble Telescope, which allows it to identify individual stars previously detected in blurry groups. It's also about 10 times as sensitive, ...

At its best, Hubble’s resolution is about 0.05 arcsecond—a very tiny angle! But how much detail it can see in real terms depends on the target’s distance and physical size.
