Hubble finds water vapour in small exoplanet’s atmosphere
Astronomers using the NASA/ESA Hubble Space Telescope observed the smallest exoplanet where water vapour has been detected in its atmosphere. At only approximately twice Earth’s diameter, the planet GJ 9827d could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy.

Hubble finds weird home of farthest fast radio burst
A Fast Radio Burst (FRB) is a fleeting blast of energy that can – for a few milliseconds – outshine an entire galaxy. Over the past few years hundreds of FRBs have been detected. They pop off all over the sky like camera flashes at a stadium event, but the sources behind these intense bursts of radiation remain uncertain.

Hubble observes a changing exoplanet atmosphere
An international team of astronomers has assembled and reprocessed observations of the exoplanet WASP-121 b that were collected with the NASA/ESA Hubble Space Telescope in the years 2016, 2018 and 2019. This provided them with a unique dataset that allowed them not only to analyse the atmosphere of WASP 121 b, but also to compare the state of the exoplanet’s atmosphere across several years. They found clear evidence that the observations of WASP-121 b were varying in time. The team then used sophisticated modelling techniques to demonstrate that these temporal variations could be explained by weather patterns in the exoplanet's atmosphere.

Hubble watches spoke season on Saturn
This photo of Saturn was taken by the NASA/ESA Hubble Space Telescope on 22 October 2023, when the ringed planet was approximately 1365 million kilometres from Earth. Hubble's ultra-sharp vision reveals a phenomenon called ring spokes.

A holiday globe of stars
To celebrate the holiday season, the NASA/ESA Hubble Space Telescope has captured the galaxy known as UGC 8091, which resembles a sparkling festive snow globe. With a dazzling array of wavelengths of light captured by filters on Hubble's premier scientific instruments, the millions of stars in this galaxy are being explored in more depth than ever before.
