☆ Planet-forming disk detected around star in another galaxy for the first time
▼ + stars: | 2023-11-30 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

CNN —For the first time, astronomers have glimpsed a young star outside the Milky Way galaxy that’s ringed by a dense disk where planets may form. The massive star, called HH 1177, and its rotating disk were spotted in the Large Magellanic Cloud, a neighboring dwarf galaxy that’s about 160,000 light-years away. The gas and dust accumulate in a flat disk around the star, known as an accretion disk, as a result of strong gravitational forces. The Multi Unit Spectroscopic Explorer, or MUSE instrument, on the telescope captured a jet of material releasing from the young star. To discern whether a disk was present around the star, the team needed to measure how quickly dense gas moved around the star.

☆ Puzzlingly massive planet found orbiting a small star
▼ + stars: | 2023-11-30 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

The planet, about the mass of Neptune and more than 13 times as massive as Earth, was detected orbiting an ultracool M-dwarf star called LHS 3154 — which is nine times less massive than our sun. This graphic compares the sizes of our sun and Earth with the smaller, cooler LHS 3154 star and its orbiting planet, LHS 3154b. For example, small M dwarf stars are the most common throughout the Milky Way galaxy, and they typically have small, rocky planets orbiting them, rather than gas giant planets. “The planet-forming disk around the low-mass star LHS 3154 is not expected to have enough solid mass to make this planet,” Mahadevan said. A team of scientists led by Mahadevan built the HPF, which was designed to detect planets orbiting within the habitable zone of small, cool stars.

Newborn stars with these circumstellar disks had been observed by astronomers only in our Milky Way galaxy - until now. Observing these disks in other galaxies is very important because it tells us about how stars form in environments different from that of the Milky Way," McLeod added. The Large Magellanic Cloud is considered a satellite galaxy of the sprawling Milky Way, as is another galaxy called the Small Magellanic Cloud. The Large Magellanic Cloud has less dust than the Milky Way and a smaller content of what astronomers call metallic elements - those other than hydrogen and helium. McLeod expressed hope for detecting other circumstellar disks in the Large Magellanic Cloud and perhaps the further Small Magellanic Cloud.

CNN —Space is full of extreme phenomena, but the “Tasmanian devil” may be one of the weirdest and rarest cosmic events ever observed. Astronomers dubbed the celestial object the “Tasmanian devil,” and they observed it exploding repeatedly following its initial detection in September 2022. But the Tasmanian devil is revealing more questions than answers with its unexpected behavior. While LFBOTs are unusual events, the Tasmanian devil is even stranger, causing astronomers to question the processes behind the repetitive explosions. We’d never seen that, period, in astronomy.”To better understand the quick luminosity changes occurring in the Tasmanian devil, Ho and her colleagues reached out to other researchers to compare observations from multiple telescopes.

As less-rigorous medical screening allows more tourists to reach space, the chances increase significantly that someone will get hurt or have a health emergency there.

New details of the celestial feature have emerged in the colorful image, which unites the observational powers of Hubble Space Telescope in visible light and the James Webb Space Telescope in infrared light, which is invisible to the human eye. Hubble has long been used to search for faint, distant galaxies across different wavelengths of light. This cosmic effect occurs when closer objects — such as the galactic clusters — act like a magnifying glass for distant objects. The Webb and Hubble composite image includes "Mothra," a star system magnified by the galactic cluster pair as well as another unseen object. NASA/ESA/CSA/STScIThe team nicknamed the star system Mothra due to its extreme magnification and brightness.

CNN —Two powerful NASA telescopes have detected the oldest and most distant black hole ever found. “We needed Webb to find this remarkably distant galaxy and Chandra to find its supermassive black hole,” said lead study author Akos Bogdan, in a statement. Potential black hole theoryTypically, black holes located at the centers of galaxies only have about 0.1% the mass of the stars within their host galaxy. The unusual black hole could be an “Outsize Black Hole” that formed when a huge cloud of gas collapsed, as theorized in 2017 by Priyamvada Natarajan, a coauthor on both studies and the Joseph S. and Sophia S. Fruton professor of astronomy and professor of physics at Yale University in New Haven, Connecticut. “We think that this is the first detection of an ‘Outsize Black Hole’ and the best evidence yet obtained that some black holes form from massive clouds of gas,” Natarajan said.

PARIS, Nov 7 (Reuters) - European astronomers on Tuesday released the first images from the newly launched Euclid space telescope, designed to unlock the secrets of dark matter and dark energy - hidden forces thought to make up 95% of the universe. Scientists believe vast, seemingly organised structures such as Perseus could only have formed if dark matter exists. "The rest of the universe we call dark because it doesn't produce light in the normal electromagnetic spectrum. Tell-tale signs of the hidden force exerted by dark matter include galaxies rotating more quickly than scientists would expect from the amount of visible matter that can be detected. We think there's lots of dark matter in that cluster and pulling these galaxies together," she added.

If you have ever wondered what it might feel like to be sucked into a black hole — twisted, stretched, confused, doomed — you could do worse than trip through “The Warped Side of Our Universe, An Odyssey Through Black Holes, Wormholes, Time Travel and Gravitational Waves,” a collaborative book project by Kip Thorne, a physicist at the California Institute of Technology, and Lia Halloran, a visual artist and chair of the art department at Chapman University in Orange, Calif.Dr. Thorne brings impressive credentials to the task. In 2017 he won the Nobel Prize in Physics for his work on the Laser Interferometry Gravitational-Wave Observatory, or LIGO, which discovered space-time vibrations resulting from the collision of two distant black holes. He was also the executive producer of the movie “Interstellar.” Ms. Halloran, who grew up surfing and skateboarding in the Bay Area, became obsessed with science after a high school internship at the Exploratorium in San Francisco. The book consists of illustrations of what Dr. Thorne likes to call the “space-time storms” predicted by general relativity, Einstein’s theory of gravity, alternating with his own explanations of the physics, which appear in verse. Many of the illustrations, which are in ink on drafting film, portray Ms. Halloran’s wife, Felicia, being whipped around, crushed and twisted by the forces of nature.

High-tide floods are not caused by the weather but by the twice monthly alignment of the Earth, sun and moon. But as climate change causes sea levels to rise, high tide floods — sometimes called nuisance floods or sunny-day floods because they can happen on clear days — are likely to inundate more coastal neighborhoods across the five boroughs. By 2050, Lower Manhattan could see 85 days of high-tide flooding annually, a fivefold increase. By the end of this century, 600,000 city residents could be affected by regular tidal flooding, according to the New York City Comptroller’s office. “Tidal flooding is a pretty significant existential climate threat,” said Louise Yeung, the chief climate officer for the comptroller’s office.

Star formation in the early galaxies occurred in occasional big bursts, they found, rather than at a steady pace. "According to the standard model of cosmology, there should not be many very massive galaxies during cosmic dawn because it takes time for galaxies to grow after the Big Bang. And the reason this is so significant is that we explain these very bright galaxies without having to break the standard cosmological model," Faucher-Giguère added. They blast gas into space that becomes ingredients for another burst of star formation. But the stronger gravitational effects in larger galaxies prevent these bursts, favoring steady star formation.
