New image reveals secrets of planet birth      (via sciencedaily.com) 

Astronomers have gained new clues about how planets as massive as Jupiter could form. Researchers have detected large dusty clumps, close to a young star, that could collapse to create giant planets.

Webb detects water vapor in rocky planet-forming zone      (via sciencedaily.com) 

Water is essential for life as we know it. However, scientists debate how it reached the Earth and whether the same processes could seed rocky exoplanets orbiting distant stars. New insights may come from the planetary system PDS 70, located 370 light-years away. The star hosts both an inner disk and outer disk of gas and dust, separated by a 5 billion-mile-wide (8 billion kilometer) gap, and within that gap are two known gas-giant planets.

In new space race, scientists propose geoarchaeology can aid in preserving space heritage      (via sciencedaily.com) 

The material record that currently exists on the moon is rapidly becoming at risk of being destroyed if proper attention isn't paid during the new space era, scientists say. They propose a new scientific subfield: planetary geoarchaeology, the study of how cultural and natural processes on Earth's moon, on Mars and across the solar system may be altering, preserving or destroying the material record of space exploration.

Galaxy J1135 reveals its water map      (via sciencedaily.com) 

Researchers look at water in galaxies, its distribution and in particular its changes of state from ice to vapor, as important markers indicating areas of increased energy, in which black holes and stars are formed. A new study has now revealed the distribution of water within the J1135 galaxy, which is 12 billion light years away and formed when the Universe was a 'teenager', 1.8 billion years after the Big Bang . This water map, with unprecedented resolution, is the first ever to be obtained for such a remote galaxy. The map can help scientists to understand the physical processes taking place within J1135 and shed light on the dynamics, still partially unclear, surrounding the formation of stars, black holes and galaxies themselves.

Does this exoplanet have a sibling sharing the same orbit?      (via sciencedaily.com) 

Astronomers have found the possible 'sibling' of a planet orbiting a distant star. The team has detected a cloud of debris that might be sharing this planet's orbit and which, they believe, could be the building blocks of a new planet or the remnants of one already formed. If confirmed, this discovery would be the strongest evidence yet that two exoplanets can share one orbit.

The puzzle of the galaxy with no dark matter      (via sciencedaily.com) 

New research has found the first evidence of a massive galaxy with no dark matter. The result is a challenge to the current standard model of cosmology.

VERA unveils surroundings of rapidly growing black holes      (via sciencedaily.com) 

Astronomers used the state-of-the-art capability of VERA, a Japanese network of radio telescopes, to uncover valuable clues about how rapidly growing 'young' supermassive black holes form, grow, and possibly evolve into more powerful quasars.

Astronomers discover striking evidence of 'unusual' stellar evolution      (via sciencedaily.com) 

Astronomers have found evidence that some stars boast unexpectedly strong surface magnetic fields, a discovery that challenges current models of how they evolve.

Giant swirling waves at edge of Jupiter's magnetosphere      (via sciencedaily.com) 

A team has found that NASA's Juno spacecraft orbiting Jupiter frequently encounters giant swirling waves at the boundary between the solar wind and Jupiter's magnetosphere. The waves are an important process for transferring energy and mass from the solar wind, a stream of charged particles emitted by the Sun, to planetary space environments.

When ET calls, can we be sure we're not being spoofed?      (via sciencedaily.com) 

In the search for extraterrestrial intelligence, alien radio signals would be swamped by interference from radio sources on Earth. To confirm, researchers point away from the source and then back. If it's still there, it may be interesting. Researchers have come up with a new method that looks for evidence the signal has passed through the interstellar medium. The technique will boost confidence in any candidate signal discovered in the future.

Hubble views a galactic monster      (via sciencedaily.com) 

The NASA/ESA Hubble Space Telescope has captured a monster in the making in this observation of the exceptional galaxy cluster eMACS J1353.7+4329, which lies about eight billion light-years from Earth in the constellation Canes Venatici. This collection of at least two galaxy clusters is in the process of merging together to create a cosmic monster, a single gargantuan cluster acting as a gravitational lens.

Stellar cradles and graves seen in farthest galaxy ever      (via sciencedaily.com)     Original source 

New observations have distinguished the sites of star formation and a possible site of star death from the surrounding nebula in a galaxy 13.2 billion light-years away. This is the farthest that such structures have been observed.

Astronomers identify the coldest star yet that emits radio waves      (via sciencedaily.com)     Original source 

Brown dwarf stars rarely emit radio waves. Here scientists have found the coldest star yet emitting at these long wave lengths. Understanding the science of 'ultracool brown dwarfs' will help deepen our knowledge of how stars evolve.

James Webb Telescope catches glimpse of possible first-ever 'dark stars'      (via sciencedaily.com) 

Three bright objects initially identified as galaxies in observations from the James Webb Space Telescope might actually represent an exotic new form of star. If confirmed, the discovery would also shed light on the nature of dark matter.

Researcher turns one of the basic rules of construction upside down      (via sciencedaily.com)     Original source 

Structural engineers are familiar with seventeenth-century scientist Robert Hooke's theory that a hanging chain will mirror the shape of an upstanding rigid arch. However, new research now shows that this common-held belief is incorrect because, regardless of the similarities, the hanging chain and the arch are two incompatible mechanical systems.

GPT detectors can be biased against non-native English writers      (via sciencedaily.com)     Original source 

Researchers show that computer programs commonly used to determine if a text was written by artificial intelligence tend to falsely label articles written by non-native language speakers as AI-generated. The researchers caution against the use of such AI text detectors for their unreliability, which could have negative impacts on individuals including students and those applying for jobs.

Number cruncher calculates whether whales are acting weirdly      (via sciencedaily.com)     Original source 

We humans can be a scary acquaintance for whales in the wild. This includes marine biologists tagging them with measuring devices to understand them better. These experiences can make whales behave erratically for a while. Such behaviour can affect research quality and highlights an animal ethics dilemma. Now, researchers have figured out how to solve the problems with math.

Deciphering the thermodynamic arrow of time in large-scale complex networks      (via sciencedaily.com) 

A solution for temporal asymmetry -- or entropy production -- in thermodynamics has been developed to further our understanding of the behavior of biological systems, machine learning, and AI tools. The researchers worked on the time-irreversible Ising model dynamics caused by asymmetric connections between neurons.
