How cosmic winds transform galactic environments

Much like how wind plays a key role in life on Earth by sweeping seeds, pollen and more from one place to another, galactic winds - high-powered streams of charged particles and gases - can change the chemical make-up of the host galaxies they form in, simply by blowing in a specific direction.

Webb telescope measures the temperature of a rocky exoplanet

An international team of researchers has used the James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet's thermal emission: heat energy given off in the form of infrared light detected by Webb's Mid-Infrared Instrument (MIRI).

Neutron star that behaves like a black hole discovered

Researchers have found a neutron star that captures matter from a companion star in a violent and unstable process. This process, previously observed only in very bright black holes, opens the door to new insights into the behaviour of stars.

AI finds that first stars were clustered together

An international team has used artificial intelligence to analyze the chemical abundances of old stars and found indications that the very first stars in the Universe were born in groups rather than as isolated single stars.

Galaxy changes classification as jet changes direction

A team of international astronomers have discovered a galaxy that has changed classification due to unique activity within its core. The galaxy, named PBC J2333.9-2343, was previously classified as a radio galaxy, but the new research has revealed otherwise.

Life on distant moons

Researchers from the fields of astrophysics, astrochemistry and biochemistry have now determined in a novel, interdisciplinary collaboration the necessary properties that allow moons around free-floating planets to retain liquid water for a sufficiently long time and thus enable life.

Largest catalog of exploding stars now available

The largest data release of relatively nearby supernovae (colossal explosions of stars), containing three years of data from thePan-STARRS telescope is publicly available via the Young Supernova Experiment (YSE).

Webb Telescope captures rarely seen prelude to supernova

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 the James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments.
