Water world? Methane, carbon dioxide in atmosphere of massive exoplanet      (via sciencedaily.com) 

A new investigation with NASA's James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. Webb's discovery adds to recent studies suggesting that K2-18 b could be a Hycean exoplanet, one which has the potential to possess a hydrogen-rich atmosphere and a water ocean-covered surface.

Ravenous black hole consumes three Earths'-worth of star every time it passes      (via sciencedaily.com) 

Massive burst of X-rays detected by astronomers indicates material three times the mass of Earth burning up in a black hole. They observed a star like our own Sun being eaten away every time it orbits close. First time a Sun-like star being repeatedly disrupted by a low mass black hole has been seen, opening the possibility of a range of star and black hole combinations to be discovered.

Furthest ever detection of a galaxy's magnetic field      (via sciencedaily.com) 

Astronomers have detected the magnetic field of a galaxy so far away that its light has taken more than 11 billion years to reach us: we see it as it was when the Universe was just 2.5 billion years old. The result provides astronomers with vital clues about how the magnetic fields of galaxies like our own Milky Way came to be.

Hot Jupiter blows its top      (via sciencedaily.com) 

The planet HAT-P-32b is losing so much of its atmospheric helium that the trailing gas tails are among the largest structures yet known any planet outside our solar system. Three-dimensional (3D) simulations helped model the flow of the planet's atmosphere. The scientists hope to widen their planet-observing net and survey 20 additional star systems to find more planets losing their atmosphere and learn about their evolution.

Webb reveals new structures within iconic supernova      (via sciencedaily.com) 

NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelengths ranging from gamma rays to radio for nearly 40 years, since its discovery in February of 1987. New observations by Webb's NIRCam (Near-Infrared Camera) provide a crucial clue to our understanding of how a supernova develops over time to shape its remnant.

Scientists detect and validate the longest-period exoplanet found with TESS      (via sciencedaily.com) 

Scientists have detected and validated two of the longest-period exoplanets found by TESS to date. These long period large exoplanets orbit a K dwarf star and belong to a class of planets known as warm Jupiters, which have orbital periods of 10-200 days and are at least six times Earth's radius. This recent discovery offers exciting research opportunities for the future of finding long-period planets that resemble those in our own solar system.

Unprecedented gamma-ray burst explained by long-lived jet      (via sciencedaily.com) 

While astrophysicists previously believed that only supernovae could generate long gamma-ray bursts (GRBs), a 2021 observation uncovered evidence that compact-object mergers also can generate the phenomenon. Now, a new simulation confirms and explains this finding. If the accretion disk around the black hole is massive, it launches a jet that lasts several seconds, matching the description of a long GRB from a merger.

Telescopes help unravel pulsar puzzle      (via sciencedaily.com) 

With a remarkable observational campaign that involved 12 telescopes both on the ground and in space, including three European Southern Observatory (ESO) facilities, astronomers have uncovered the strange behavior of a pulsar, a super-fast-spinning dead star. This mysterious object is known to switch between two brightness modes almost constantly, something that until now has been an enigma. But astronomers have now found that sudden ejections of matter from the pulsar over very short periods are responsible for the peculiar switches.
