Supernova 1987A, imaged by the Hubble and JWST. The faint blue source in the centre is the emission detected with the JWST/NIRSpec instrument. The bright stars to the left and right of the inner ring are unrelated to the supernova. Credit: Hubble Space Telescope WFPC-3/James Webb Space Telescope NIRSpec/J. Larsson

Evidence grows for a young ocean lurking under Mimas’ surface

In this artist's conception, a black hole (center) is contained in a small host galaxy in the distant universe (left). In the nearby universe (right), the same sized black hole would be hosted in a much bigger galaxy. Credit: CfA/Melissa Weiss

JWST turns up even more heavier-than-expected black holes

A Hubble Space Telescope image of the host galaxy of an exceptionally powerful fast radio burst, FRB 20220610A. Hubble’s sensitivity and sharpness reveals a compact group of multiple galaxies that may be in the process of merging. They existed when the universe was only 5 billion years old.

Scientists find a direct link from the death of massive stars to black holes and neutron stars

Voyager’s views of Jupiter’s colorful cloud tops reminded many people of an impressionist painter’s canvas. Fine details in and around the Great Red Spot changed significantly in the four months between the Voyager 1 flyby and Voyager 2 (pictured). Credit: NASA/JPL.

Astronomers capture a green ghost in our atmosphere

An artist’s rendering of the warm exoplanet WASP-80 b whose color may appear bluish to human eyes due to the lack of high-altitude clouds and the presence of atmospheric methane identified by NASA’s James Webb Space Telescope, similar to the planets Uranus and Neptune in our own solar system.

Astronomers discover disk around star in another galaxy for the 1st time ever

Light from 23 distant galaxies, identified with red rectangles in the Hubble Space Telescope image at the top, were combined to capture incredibly faint emission from eight different elements, which are labelled in the JWST spectrum at the bottom. Although scientists regularly find these elements on Earth, astronomers rarely, if ever, observe many of them in distant galaxies. Credit: Aaron M. Geller, Northwestern, CIERA + IT-RCDS
