JWST sees four exoplanets in a single system

When the JWST activated its penetrating infrared eyes in July 2022, it faced a massive wish-list of targets compiled by an eager international astronomy community. Distant, early galaxies, nascent planets forming in dusty ...

JWST takes a detailed look at Jupiter's moon Ganymede

Nature doesn't conform to our ideas of neatly-contained categories. Many things in nature blur the lines we try to draw around them. That's true of Jupiter's moon Ganymede, the largest moon in the solar system

New observations confirm important step in star formation

New observations have confirmed a key step in the process of star formation: a rotating "cosmic wind" made of molecules, which is vitally important for collapsing gas clouds to contract sufficiently so as to form a hot, dense ...

Protostars can siphon material from far away, says study

When stars are born, they do it inside a molecular cloud. Astronomers long assumed that the "crèche" supplied all the nutrients that protostars needed to form. However, it turns out they get help from outside the nest.

Central star in a planetary nebula reveals details of its life

Stars like our sun end their lives as white dwarfs. Some of them are surrounded by a planetary nebula consisting of gas ejected by the dying star shortly before its death. An international research team led by Professor Klaus ...

New Gaia release: Cluster cores and unforeseen science

ESA's Gaia provides many new and improved insights into our galaxy and beyond with the release of five new data products. Among other findings, the mission reveals half a million new and faint stars in a massive cluster. ...
