Big surprise from planet-forming disk around small star
Stars form when dense clumps of interstellar gas and dust collapse under their own gravitational force. When a star emerges at the center of such a cloud, the remaining material forms a swirling disk around it that fuels stellar evolution and often gives birth to planets. The disks around newborn Sun-sized stars contain much more…

Webb telescope again discovers the most distant galaxy ever seen
The James Webb Space Telescope has set a new record for the most distant known galaxy, an extremely bright star system that formed 290 million years after the Big Bang, NASA said Thursday. Since coming online in 2022, the Webb telescope has ushered in a new era of scientific breakthroughs, looking farther into the distant…

The Sun's magnetic field may originate close to the solar surface
“If the plasma that makes up the sun were completely static, we know that the sun's magnetic field would decay over time, and pretty soon, there would be no sunspots or other solar activity. However, the plasma in the sun is moving, and that motion is able to regenerate and maintain the sun's magnetic field,”…

Astronomers have finally discovered a rocky planet with an atmosphere
Being so close to its star, any atmosphere should be stripped away by stellar radiation and winds. But dissolved gases in the vast lava ocean covering the planet can keep boiling to refill the atmosphere, Hu said. “The planet may not be habitable because it is so hot that it does not contain liquid water,…

T. rex at center of debate over dinosaur intelligence
“However, looking at living animals, we see that neuron count is actually not a good indicator of intelligence, although this may seem intuitive at first glance,” Kasper said. Dinosaurs, apart from their bird descendants, disappeared after an asteroid hit Earth 66 million years ago. Over two centuries of scientific study, dinosaurs are coming into better…

Scientists identify neutron star born from supernova seen in 1987
“After following supernovae and searching for compact objects for more than three decades, it is exciting to finally find the missing evidence for a neutron star,” said lead author Claes Fransson, professor of astrophysics at Stockholm University in Sweden, to JWST. Thank you.” According to the study published in Science Journal. “Neutron stars are extremely…

AI reads ancient scrolls buried by Vesuvius eruption
As an alternative, the Vesuvius Challenge took high-resolution CT scans of four scrolls and offered one million dollars, among several prizes to encourage research on them. The prize-winning trio included Joseph Nader, a PhD student in Berlin, Luke Ferriter, a student and SpaceX trainee from Nebraska, and Swiss robotics student Julian Schilliger. The group used…

Scientists conclude New Mexico fossil is new Tyrannosaurus species
“It is the nature of the species that the differences are subtle. The main thing is that they are consistent. We looked at many different T-rexes, and our animal was consistently different from every known T-rex, in every bone,” Longrich he said. The researchers said the differences included important traits. Fiorillo said the feature above…

Scientists identify new species of dinosaur from footprints in Brazil
Fossil dinosaur “trackways”, as scientists call them, were first found in the 1980s by Italian priest and paleontologist Giuseppe Leonardi in what is today the city of Araraquara in São Paulo state. Leonardi donated to the Brazilian Museum of Earth Sciences (MCTER) in 1984 one of the footprint specimens found in the so-called Botucatu Formation,…

Scientists discover interior structure of mysterious dwarf planet Eris
Eris’ interior appears to be rocky beneath an ice shell, researchers said Wednesday. Pluto’s exterior is icy and rocky below, but it has a higher ice content and is thought to have an underground liquid ocean. “We already knew that Eris is more rock-rich than Pluto, but we didn’t know whether Eris had rock separated…

Euclid Space Telescope reveals stunning images of the dark universe
European astronomers on Tuesday released the first images from the newly launched Euclid space telescope, designed to uncover the mysteries of dark matter and dark energy – hidden forces thought to account for 95 percent of the universe. The European Space Agency, which leads the six-year mission as a partner with NASA, said the images…

Scientists have detected oxygen in the harmful atmosphere of Venus
Oxygen was found to be concentrated at an altitude of about 60 miles (100 km) between those two crustal layers. Oxygen temperatures on the planet ranged from minus 184 degrees Fahrenheit (minus 120 degrees Celsius) during the day to minus 256 degrees Fahrenheit (minus 160 degrees Celsius) at night. Methods previously used to detect daytime…

Astronomers discover seven planets ‘fried’ by their star in the Milky Way
“All the planets have been ‘roasted’ more intensely than any other planet in our solar system,” said astronomer Jack Lissauer of NASA’s Ames Research Center in California. On the arXiv research site. Scientists have so far identified more than 5,500 exoplanets – planets outside our solar system – and observed hundreds of stars with many…

Close encounter with ‘alien bodies’ in Mexico
Mawson shared the results of DNA and carbon dating tests he conducted on the “creatures” on social media and in his presentation. A Mexican scientist reviewed the results at the request of Reuters and concluded that they indicated normal life on Earth. Mawson told Reuters on Friday that the test results were not directly related…

Supermassive black hole caught in the act of swallowing a Sun-like star
Black holes, celestial bodies known for their gluttony, usually devour so many unlucky stars that they get too close to them in one big gulp, destroying them with their enormous gravitational pull. But it turns out that some people prefer to have breakfast instead of filling their stomach. Researchers say they have watched a supermassive…
