JWST data resolve a puffy hot Jupiter's atmosphere into a ring with raised 'gems'

Astronomers used JWST data and a technique called transmission strings to map WASP-17b's atmosphere as a ring with raised 'gems'. The temperature contrast they found matches theory, so the result is a test of the method.

Black holes of very different mass seem to launch jets at the same feeding threshold

Curtin-led astronomers report that black holes differing in mass by millions of times appear to launch jets at the same stage of their feeding cycle. If the pattern holds, delayed radio flares after stellar disruptions could be timed from the feeding rate.

JWST transit data show WASP-17b's atmosphere is more extended on its evening side

Cornell and Bristol researchers applied transmission strings to JWST data and found WASP-17b's atmosphere more extended on one side. The shape matches theoretical predictions, so the study is a first test of the method on one planet.

MIT astronomers find a star slowly stripping a brown dwarf 300 light-years away

MIT-led astronomers found a star about 300 light-years away slowly pulling material off a brown dwarf companion, a process that could last billions of years. One detection shows slow stripping happens, and working out how common it is will need a larger sample of such pairs.

Niobium in old Hubble spectra points to a planet that may have formed after its star died

Astronomers re-reading 1999 Hubble spectra of white dwarf HS 0209+0832 found unusually high niobium that may trace matter the star shed as it died. The team proposes that some of that debris built a gas giant hinted at in TESS data, though the planet remains a candidate.

Niobium-rich white dwarf points to a planet built from material its own star cast off

Warwick-led astronomers tie niobium at over 1,000 times solar levels in a white dwarf to a candidate planet made from what the star shed as it died. If it holds up, it shows planets can still form after a star has died.

Solar Orbiter traces a magnetic switchback to hot loops on the Sun's surface

Solar Orbiter flew through a large magnetic switchback and used the particles inside it to trace the kink to a source on the Sun's surface. The result comes from a single crossing, so it limits how switchbacks can begin but cannot yet say how most of them do.

Warwick and MIT teams find two dwarf stars that appear to be eating their companions

Two Nature Astronomy studies report a red dwarf drawing material off a brown dwarf and a white dwarf apparently fed by a second-generation planet. Each rests on a single system, so together they show that such feeding happens and leave open how often it does.

JWST catches galaxies pushing carbon and oxygen into space 500 million years after the Big Bang

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.

Mantle chemistry suggests Earth grew mostly by pebble accretion and Mars mostly from planetesimals

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 team designs a suitcase-sized satellite to hear hydrogen from before the first stars

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.

The Milky Way's Oldest Known Meal: 39 Globular Clusters Push Its Merger Record Back 1.8 Billion Years

A 21-centimetre stack of 2.5 million galaxies exonerates the cosmic gas supply

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.

Eighty-four hypersoft X-ray sources surfaced in Chandra channels astronomers had skipped

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.

White dwarf RXJ0528+2838 has driven a bow shock for at least 1,000 years without a disc

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.

Three JWST sightlines put carbon and oxygen outside galaxies 500 million years after the Big Bang

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.
