Published Baby star near the black hole in the middle of our Milky Way: It exists after all
(via sciencedaily.com) Scientists have detected the heaviest and youngest infant star ever discovered close to the black hole at the center of our Galaxy. They also identified the region where this 'impossible star' may have formed.
Published Liquid nitrogen spray could clean up stubborn moon dust
(via sciencedaily.com) A liquid nitrogen spray can remove almost all of the simulated moon dust from a space suit, potentially solving what is a significant challenge for future moon-landing astronauts.
Published A mysterious object is being dragged into the supermassive black hole at the Milky Way's center
(via sciencedaily.com) An object near the supermassive black hole at the center of the Milky Way galaxy has drawn the interest of scientists because it has evolved dramatically in a relatively short time. A new study suggests that the object, called X7, could be a cloud of dust and gas that was created when two stars collided. The researchers believe it will eventually be drawn toward the black hole and will disintegrate.
Published New discovery sheds light on very early supermassive black holes
(via sciencedaily.com) Astronomers have discovered a rapidly growing black hole in one of the most extreme galaxies known in the very early Universe. The discovery of the galaxy and the black hole at its center provides new clues on the formation of the very first supermassive black holes.
Published How one of Saturn's moons ejects particles from oceans beneath its surface
(via sciencedaily.com) Enceladus, the sixth largest of Saturn's moons, is known for spraying out tiny icy silica particles -- so many of them that the particles are a key component of the second outermost ring around Saturn. Scientists have not known how that happens or how long the process takes. A study now shows that tidal heating in Enceladus' core creates currents that transport the silica, which is likely released by deep-sea hydrothermal vents, over the course of just a few months.
Published Plastic upcycling to close the carbon cycle
(via sciencedaily.com) Original source A new method to convert waste plastic to fuel and raw materials promises to help close the carbon cycle at mild temperature and with high yield.
Published Why do Earth's hemispheres look equally bright when viewed from space?
(via sciencedaily.com) When seen from space, Earth's hemispheres -- northern and southern -- appear equally bright. For years, the brightness symmetry between hemispheres remained a mystery. In a new study, researchers reveal a strong correlation between storm intensity, cloudiness and the solar energy reflection rate in each hemisphere. They offer a solution to the mystery, alongside an assessment of how climate change might alter the reflection rate in the future.
Published 'Forbidden' planet orbiting small star challenges gas giant formation theories
(via sciencedaily.com) Astronomers have discovered an unusual planetary system in which a large gas giant planet orbits a small red dwarf star called TOI-5205. Their findings challenge long-held ideas about planet formation.
Published Ramping up domestic graphite production could aid the green energy transition
(via sciencedaily.com) Given the growing importance of graphite in energy storage technologies, a team of esearchers has conducted a study exploring ways to reduce reliance on imports of the in high-demand mineral, which powers everything from electric vehicles (EVs) to cell phones.
Published Meteorite crater discovered in French winery
(via sciencedaily.com) Countless meteorites have struck Earth in the past and shaped the history of our planet. It is assumed, for example, that meteorites brought with them a large part of its water. The extinction of the dinosaurs might also have been triggered by the impact of a very large meteorite. It turns out that the marketing 'gag' of the 'Domaine du Météore' winery is acutally a real impact crater. Meteorite craters which are still visible today are rare because most traces of the celestial bodies have long since disappeared again.
Published James Webb spots super old, massive galaxies that shouldn't exist
(via sciencedaily.com) A team of international researchers have identified six candidate galaxies that existed roughly 500 to 700 million years after the Big Bang and are about as big as the modern Milky Way Galaxy -- a feat that scientists didn't think was possible.
Published Better tools needed to determine ancient life on Mars
(via sciencedaily.com) Current state-of-the-art instrumentation being sent to Mars to collect and analyze evidence of life might not be sensitive enough to make accurate assessments, according to new research.
Published Researchers discover mysterious source of 'heartbeat-like' radio bursts in a solar fare
(via sciencedaily.com) A solar radio burst with a signal pattern, akin to that of a heartbeat, has been pinpointed in the Sun's atmosphere, according to a new study. An international team of researchers has reported uncovering the source location of a radio signal coming from within a C-class solar flare more than 5,000 kilometers above the Sun's surface.
Published Improving the performance of satellites in low Earth orbit
(via sciencedaily.com) On-chip distributed radiation sensors and current-sharing techniques can be used to reduce the impact of radiation on the radio and power consumption of small satellites, respectively. New findings can be used to make small satellites more robust, which can increase the connectivity of networks across the globe.
Published Newly discovered form of salty ice could exist on surface of extraterrestrial moons
(via sciencedaily.com) Original source An international team has found two new crystal structures for salty ice, or solid hydrate made from water and sodium chloride. The newly discovered material's properties match those of the substance seen on the surface of icy moons, like Europa and Ganymede, and may offer clues to their icy oceans.
Published Space travel influences the way the brain works
(via sciencedaily.com) Original source Scientists have found how the human brain changes and adapts to weightlessness, after being in space for 6 months. Some of the changes turned out to be lasting -- even after 8 months back on Earth.
Published Tadpole playing around black hole
(via sciencedaily.com) Original source A peculiar cloud of gas, nicknamed the Tadpole due to its shape, appears to be revolving around a space devoid of any bright objects. This suggests that the Tadpole is orbiting a dark object, most likely a black hole 100,000 times more massive than the Sun. Future observations will help determine what is responsible for the shape and motion of the Tadpole.
Published Study quantifies global impact of electricity in dust storms on Mars
(via sciencedaily.com) Mars is infamous for its intense dust storms, some of which kick up enough dust to be seen by telescopes on Earth. When dust particles rub against each other, as they do in Martian dust storms, they can become electrified. New research shows that one particularly efficient way to move chlorine from the ground to the air on Mars is by way of reactions set off by electrical discharge generated in dust activities.
Published Four classes of planetary systems
(via sciencedaily.com) Astronomers have long been aware that planetary systems are not necessarily structured like our solar system. Researchers have now shown that there are in fact four types of planetary systems.
Published Upsurge in rocket launches could impact the ozone layer
(via sciencedaily.com) Researchers have summarized the threats that future rocket launches would pose to Earth's protective ozone layer.
