A Japanese space probe performed a flyby of a near-Earth asteroid on Sunday in a test mission for technology that could help protect the planet from space rocks. Go to Source Astronomers have uncovered a pair of giant planets that are lighter than cotton candy—super-puffs the size of Jupiter. Go to Source The 1.7 million satellites that companies are aiming to launch into Earth’s orbit in the coming years will have “devastating consequences for astronomy,” new research warned Wednesday. Go to Source Astronomers have spotted many “red and dead” galaxies in the early universe. These are massive systems that stopped forming stars surprisingly early in cosmic history. Now, they may have found evidence of one in the act of becoming dead: a massive galaxy being stripped of its star-forming gas just 1.4 billion years after the Big […] Planets beyond our solar system can have magnetic fields similar to those closer to home, astronomers said Tuesday after observing extreme winds on scorching worlds known as “hot Jupiters.” Go to Source An international team of astronomers reports the discovery of a new massive barred spiral galaxy. The newfound galaxy, designated M1149-BSG-z5, was identified using the James Webb Space Telescope (JWST). The finding was detailed in a paper published June 23 on the preprint server arXiv. Go to Source Short-lived sources of radio radiation in the sky, known as radio transients, can originate in the vicinity of supermassive black holes in the centers of galaxies. They are the result of processes that take place under extreme physical conditions. While most radio transients associated with galactic centers last only days or weeks, the galaxy SDSS […] More than 500,000 stars blaze red, white, and blue in this image from NASA’s Hubble Space Telescope, released in celebration of the United States’ 250th anniversary. The image showcases Messier 3 (M3), one of the Milky Way galaxy’s most massive globular clusters, or spherical collections of gravitationally bound stars. Globular clusters are made up of […] Neutrinos: They have no electric charge, pass through matter like a ghost and are so light they were initially thought to have zero mass. These are just some of the traits that make them so difficult to detect. Research on neutrinos requires massive underground observatories far from potential confounders that drown out their weak signals. […] A three-armed spacecraft rocketed into orbit Friday to rescue a NASA telescope that’s in danger of crashing back to Earth. Go to Source The moon is not the only natural object traveling through space alongside Earth. Several small asteroids travel around the sun in near lockstep with our planet. And just like Earth, these space rocks also take a year to complete a full orbit. Today, we know of eight such “quasi-moons” or quasi-satellites. Go to Source […] Indian startup Skyroot Aerospace said Thursday it would hold the maiden test flight of the country’s first privately developed orbital-class rocket in the coming weeks. Go to Source Of the known things in the universe, black holes are among the most extreme. They pack huge amounts of mass densely into a small area, producing gravity that is so strong that even light cannot escape. To describe their properties, physicists have relied on complex equations from Einstein’s theory of general relativity and quantum mechanics. […] What makes a star a star? A strange ‘in‑between’ celestial object is testing astronomers’ boundariesA star called TOI-2155 lies around 1,350 light-years (839 trillion miles) from Earth. It is a little bigger, heavier and hotter than the sun, and it is not particularly interesting or unusual in itself. Go to Source A rush rescue mission to save a NASA space telescope remains grounded, this time because of a last-minute launch problem. Go to Source |
