There are no confirmed exomoons, moons orbiting distant exoplanets in other solar systems. There are a few candidates, but none have passed the threshold and been accepted as confirmed. But they must exist. Moons are common in our solar system, so it would be extremely weird if they didn’t exist elsewhere. Go to Source […] The interstellar object known as 3I/ATLAS just flew past Mars, and China’s Tianwen-1 mission managed to snap some pics with its high-resolution camera. According to the China National Space Agency (CNSA), the orbiter’s high-resolution camera captured images of the comet from a distance of about 30 million km (18.6 million mi). This makes the Tianwen-1 […] Before atomic elements came together, less than a second after the Big Bang, if particles condensed into halos of matter, these halos may then have collapsed, creating the first black holes, boson stars, and so-called cannibal stars. This is the conclusion of a new study just published in Physical Review D, conducted by a team […] The Southern African Large Telescope (SALT) celebrates 20 years of observing the sky. SALT is the largest optical telescope in the southern hemisphere. It’s been steadily revealing new science knowledge, ranging from the discovery of planets outside our solar system to understanding the unusual physics around black holes. It’s also 20 years of doing science […] Models help scientists understand everything from the particles that make up the universe to massive superstructures of galaxies at the beginning of time. But sometimes they model more mundane, though perhaps even more complex, features—including the course of human civilization. A new paper by Thomas Leppard of the International Archaeological Research Institute and his co-authors, […] During the 1240s, Richard Fishacre, a Dominican friar at Oxford University, used his knowledge of light and color to show that the stars and planets are made of the same elements found here on Earth. In so doing, he challenged the scientific orthodoxy of his day and preempted the methods and discoveries of the 21st-century […] We know of three interstellar objects (ISO) that have visited our inner solar system. Oumuamua was the first one, and it came and went in 2017. 2l/Borisov, an interstellar comet, was next, appearing in 2019. And right now, the interstellar comet 3I/Atlas is enjoying a visit to the sun-warmed inner solar system. Go to Source […] In 2023, astronomers detected a huge collision. Two unprecedentedly massive black holes had crashed an estimated 7 billion light-years away. The enormous masses and extreme spins of the black holes puzzled astronomers. Black holes like these were not supposed to exist. Go to Source It’s almost become expected that many space telescopes and probes can have “extended missions.” Both Voyagers are still sending data back 40+ years after their five-year primary mission ended. But figuring out what to do with those spacecraft after their primary mission takes some negotiation. One such craft that will reach its end-of-mission in 2030 […] Astronomers from Keele University in the UK have utilized NASA’s planet-hunting TESS telescope to investigate a totally-eclipsing binary known as UZ Draconis. Results of the new observations, published October 31 on the arXiv pre-print server, put more constraints on the properties of this system. Go to Source Last week, four lasers were projected into the sky above the European Southern Observatory (ESO) Paranal site in Chile. The lasers successfully created an “artificial star” that astronomers can use to measure and then correct the blur caused by Earth’s atmosphere, ESO announced today. Go to Source Blue Origin, the space company owned by billionaire Jeff Bezos, was forced Sunday to postpone the anticipated launch of its New Glenn rocket due to unfavorable weather conditions. Go to Source New Glenn, the towering rocket built by Jeff Bezos’s space company Blue Origin, is set to take off on its second mission Sunday as competition intensifies with Elon Musk’s SpaceX. Go to Source Conditions on Venus’s surface have largely remained a mystery for decades. Carl Sagan famously pointed out that people were quick to jump to conclusions, such as that there are dinosaurs living there, from scant little evidence collected from the planet. But just because we have little actual data doesn’t mean we can’t draw conclusions, and […] A new study led by researchers from Oxford University, Southwest Research Institute and the Planetary Science Institute in Tucson, Arizona has provided the first evidence of significant heat flow at Enceladus’s north pole, overturning previous assumptions that heat loss was confined to its active south pole.
