Hubble – as interplanetary meteorologist – is keeping track of the outer planets' weather, as it does every year.

NASA’s Webb Spots Swirling, Gritty Clouds on Remote Planet

03.22.2023

Researchers observing with NASA’s James Webb Space Telescope have pinpointed silicate cloud features in a distant planet’s atmosphere. The team, led by Brittany Miles of the University of Arizona, also made extraordinarily clear detections of water, methane and carbon monoxide with Webb’s data, and found evidence of carbon dioxide.

Hubble Sees a Diminutive Dwarf Galaxy

UGCA 307 hangs against an irregular backdrop of distant galaxies in this image from the NASA/ESA Hubble Space Telescope.

NASA’s Webb Telescope Captures Rarely Seen Prelude to Supernova

03.14.2023

The rare sight of a Wolf-Rayet star – among the most luminous, most massive, and most briefly detectable stars known – was one of the first observations made by NASA’s James Webb Space Telescope in June 2022.

Hubble Spots a Star-Forming Spiral

The irregular spiral galaxy NGC 5486 hangs against a background of dim, distant galaxies in this image from the NASA/ESA Hubble Space Telescope.

Millions of Galaxies Emerge in New Simulated Images From NASA's Roman

03.08.2023

Scientists have created a gargantuan synthetic survey that shows what we can expect from the Nancy Grace Roman Space Telescope’s future observations. Though it represents just a small chunk of the real future survey, this simulated version contains a staggering number of galaxies – 33 million, along with 200,000 foreground stars in our home galaxy.

Hubble Peers at a Galactic Seascape
