Astronomers used Uranus as a proxy for similar planets beyond our solar system, known as exoplanets, comparing ...

A NASA Hubble Space Telescope observation program called OPAL (Outer Planet Atmospheres Legacy ... is the only telescope that can provide high spatial resolution and image stability for global ...

This is a montage of Hubble Space Telescope views of our solar system's four giant outer planets: Jupiter, Saturn, Uranus, and Neptune, each shown in enhanced color. The images were taken over ...

Yet Hubble's discovery was controversial. Perceived wisdom had been that planets could not have formed so early in the 13.7-billion-year history of the universe because there hadn't been enough ...

Giant, gas-rich planets may have been able to form more easily in the very early universe than they do today, according to astounding new findings from the James Webb Space Telescope (JWST) that ...

NASA and ESA’s Hubble Space Telescope has been observing the outer planets through a program called OPAL (Outer Planet Atmospheres Legacy). This initiative focuses on tracking Jupiter, Saturn, Uranus, ...

A star about 1,360 light-years away from Earth, named FU Orionis, is twice as hot as astronomers previously suspected, according to recent data from the Hubble Space Telescope. In fact, scientists ...

Hubble Space Telescope observations of white dwarf star G238-44 has shown that it is "consuming both rocky-metallic and icy material, the ingredients of planets," according to NASA's Goddard Space ...
