Using telescopes capable of detecting X-rays, a team of astronomers has for the first time observed this area — called the “plunging region” — in a black hole about 10,000 light-years from Earth. The study’s findings could help astronomers better understand the formation and evolution of black holes. One thing that’s missing from the study is an actual image of the black hole, because it is too small and far away. But another team of Oxford researchers is working on something even better than a picture: the first movie of a black hole. “For example, it can be used to measure the rotation rate of the black hole,” said Reynolds, who was not involved in the study.

CNN —Close flybys of Io, one of Jupiter’s moons and the most volcanically active world in our solar system, have revealed a lava lake and a towering feature called “Steeple Mountain” on the moon’s alien surface. “We also got some great close-ups and other data on a 200-kilometer-long (127-mile-long) lava lake called Loki Patera. Juno detected the mountain with the help of the sun shining on Io’s surface, which created dramatic shadows that revealed a very sharp peak. NASA/JPL-Caltech/SwRI/MSSSAs an outdoors enthusiast, Bolton joked that Io’s Steeple Mountain should be one of the solar system’s skiing and snowboarding destinations. The mission team used Juno’s Microwave Radiometer instrument to create maps of Io’s surface, showing how incredibly smooth it is.

Everywhere in our universe, a basic physical law applies: the greater the mass of an object, the stronger its gravitational field. The accumulated mass of fame and political status places Donald J. Trump at the center of most rooms he finds himself in. If he were to storm out of court suddenly, as he has in other proceedings, it would be the biggest news of the day. But in court, unlike almost everywhere else, Mr. Trump has competition: The judge, Juan M. Merchan, exudes his own gravity and has power Mr. Trump does not. And on Thursday, after a new pool of 96 prospective jurors walked into the high-ceilinged room, their attention slid from the former president seated at the defense table to the judge.

☆ ‘Sleeping giant’ massive black hole found in the Milky Way galaxy
▼ + stars: | 2024-04-16 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

CNN —Astronomers have spotted the most massive known stellar black hole in the Milky Way galaxy after detecting an unusual wobble in space. The wobbling movement of an old giant star in the Aquila constellation revealed that it was in an orbital dance with a dormant black hole, and it’s the third such dormant black hole spotted by Gaia. So Gaia BH3 is the most massive black hole in our galaxy that formed from the death of a massive star. Stellar black holes observed across the Milky Way galaxy are about 10 times as massive as the sun on average. True to expectations, the researchers found that the star orbiting Gaia BH3 was metal-poor, which means that the star that formed Gaia BH3 was likely the same.

☆ Mars could be creating 'giant whirlpools' deep within our planet's oceans
▼ + stars: | 2024-03-13 | by ( Marianne Guenot | ) www.businessinsider.com time to read: +5 min

Mars may be 140 million miles away, but its gravitational pull could be impacting Earth's oceans. Scientists at the University of Sydney in Australia believe the red planet's tug is creating "giant whirlpools" in the oceans called eddies, which can shift the deep-sea floor. This, they claim, is part of a 2.4-million-year climate "grand cycle" on Earth that has been ongoing for at least 40 million years. The red planet's orbit and ours are locked in an intricate dance, and every so often, these line up so that Mars' gravitational pull on Earth is just a little more intense — this is called resonance. This information is crucial when refining models helping us see how our planet's intricate climate will progress over time.

☆ Mars could be driving ‘giant whirlpools’ in the Earth’s deep oceans, new study finds
▼ + stars: | 2024-03-12 | by ( Laura Paddison | ) edition.cnn.com time to read: +5 min

CNN —Mars may be around 140 million miles away from Earth, but the red planet is influencing our deep oceans by helping drive “giant whirlpools,” according to new research. The sediments revealed that deep-sea currents weakened and strengthened over 2.4 million-year climate cycles, according to the study published Tuesday in the journal Nature Communications. For the Earth, this interaction with Mars translates to periods of increased solar energy — meaning a warmer climate — and these warmer cycles correlate with more vigorous ocean currents, the report found. The authors describe these currents, or eddies, as “giant whirlpools” that can reach the bottom of the deep ocean, eroding the seafloor and causing large accumulations of sediments, like snowdrifts. Deep-sea sediments build in continuous layers during calm conditions but strong ocean currents disrupt this, leaving a visible stamp of their existence.

The black hole powering the quasar devours the equivalent of one sun per day and has a mass about 17 billion times that of our sun, the researchers found. A black hole is massive power sourceThe intense gravitational influence of black holes draws matter toward these celestial objects in such an energetic way that the process creates light. The blinding radiation is due to the black hole’s accretion disk, or the ring around the black hole where material gathers before being consumed. The team followed up with observations from the powerful Very Large Telescope in Chile’s Atacama Desert to confirm details about the black hole, including its hefty mass.

CNN —Astronomers have uncovered additional evidence that one of Saturn’s smallest moons, Mimas, is hiding a global ocean beneath its icy surface. Discovered in 1789 by English astronomer William Herschel as a tiny dot near Saturn, Mimas was first imaged from space by the Voyager probes in 1980. Craters cover the surface of Mimas, but the largest one is 80 miles (about 130 kilometers) across and causes the moon to resemble the Death Star from the “Star Wars” films. But Saturn’s Enceladus appears younger because active geysers have contributed to resurfacing, or depositing of new, fresh material on that moon’s surface. “Mimas certainly demonstrates that moons with old surfaces can be hiding young oceans, which is pretty exciting,” Rhoden said.

CNN —More than half of the world’s population live in urban areas where nature can feel like a distant concern. Thriving ecosystems do, however, exist within our cities — even beneath our feet — and embracing urban nature can be a powerful force for change. Cape Town’s baboons can often be found rummaging through garbage cans and around backyards, putting them at greater risk of conflict with humans. Easy access to food from Cape Town’s trash means baboons spend less time and energy foraging, and more on socializing with potential mates and the rest of their group. The city has begun taking proactive measures to keep them away from Cape Town’s outskirts and in their natural hillside habitat.

[1/2] An undated handout image shows an artistic rendering of the mass comparison of the star LHS 3154 and its planet LHS 3154b, and our own Earth and Sun. The mass ratio of this planet with its star is more than 100 times greater than that of Earth and the sun. "We discovered a planet that is too massive for its star," said Penn State astronomer Suvrath Mahadevan, one of the leaders of the study published this week in the journal Science. The planet, called LHS 3154 b, orbits at about 2.3% of Earth's orbital distance from the sun, circling its star every 3.7 days. So a very low mass star should have a disk that is also low mass.
