University of Arizona astronomers used JWST to detect carbon and oxygen flowing out of three galaxies seen 500 million years after the Big Bang. The result suggests heavy elements spread earlier than astronomers expected, though three galaxies picked from hundreds of spectra cannot yet show how common such outflows were.

University of Copenhagen researchers estimate at least 75% of Earth's mass came via pebble accretion and about three-quarters of Mars' from planetesimals. On this evidence, rocky neighbours can grow by different routes, though the models have to assume what the building blocks were made of.

Cambridge-led researchers plan to fly the suitcase-sized CosmoCube around the Moon and collect about 1,000 hours of Earth-shielded radio data over two years. It will listen for hydrogen's 21-centimetre signal from the roughly 150 million years before the first stars, an era no one has directly observed.

Hubble imaging and Gaia orbits separate a third population of ancient star clusters in the galaxy's inner regions, evidence of a dwarf galaxy swallowed about 11.8 billion years ago.

Star formation has fallen to under half its rate of 4.5 billion years ago, but a FAST and DESI measurement finds the atomic hydrogen reservoir down only about a third, which moves the bottleneck downstream.

The 84 detections came out of public Chandra data on six galaxies with no new observing time, and the class is defined by a spectral shape that co-author Jimmy Irwin thinks may cover three different kinds of stellar remnant.

Astronomers find white dwarf RXJ0528+2838 has sustained a bow shock for at least 1,000 years with no disc to power it. Its strong magnetic field may account for part of that, and the team says an unexplained energy source may supply the rest.

A hand search of public JWST spectra turned up three galaxies whose outflowing gas carried carbon, oxygen and silicon 500 million years after the Big Bang. The search was done by eye, so the three cases show that enrichment happened while leaving its frequency open.

Andrew Mummery and Adelle Goodwin report that late radio jets in ten star-shredding events switched on as the feeding rate fell to about 2% of the Eddington limit, the threshold already known from Milky Way black holes.

A Yale-led team could not sample planetesimals from the first million years, because every one of them melted, so it reconstructed their make-up from sulfur and iron oxidation in iron meteorites and got 8% to 17% icy dust.

Mars has no moving plates, so its crust was assumed to have formed simply. A new reading of InSight's marsquake records suggests instead that molten rock evolved and reprocessed itself through the whole thickness of it.
