☆ Telescope in Utah detects mysterious cosmic ray beyond our galaxy
▼ + stars: | 2023-11-25 | by ( Rebecca Rommen | ) www.businessinsider.com time to read: +3 min

AdvertisementSpace scientists from the University of Utah and the University of Tokyo have identified an exceedingly rare, ultra-high-energy cosmic ray believed to have traveled from beyond the Milky Way galaxy. Named the "Amaterasu particle" after the Japanese sun goddess, it is a subatomic entity, invisible to the naked eye. However, high-energy cosmic rays, like the Amaterasu particle, are exceptional and are thought to come from other galaxies and extragalactic sources. AdvertisementUnlike low-energy cosmic rays, whose origins are traceable, ultra-high-energy particles like this appear to come from seemingly empty spaces. The Amaterasu particle is believed to originate from the Local Void, an empty region bordering the Milky Way galaxy.

It rivals the single most energetic cosmic ray ever observed, the “Oh-My-God” particle that was detected in 1991, the study found. “When you get out to these really high-energy (cosmic rays), it’s more like one per square kilometer per century. It’s never going through your hand.”One of the cosmic ray detectors that make up the Telescope Array, which is based in Utah. Tracking high-energy cosmic raysThe recently discovered particle, nicknamed the Amaterasu particle after the sun goddess in Japanese mythology, was spotted by a cosmic ray observatory in Utah’s West Desert known as the Telescope Array. The atmosphere largely protects humans from any harmful effects from the particles, though cosmic rays sometimes cause computer glitches.

Scientists have obtained the first ever proof that black holes can lose energy. They've long believed that magnetic fields could suck energy out of black holes but didn't have proof — until now. The M87 supermassive black hole is emitting energy like "million-light-year-long Jedi lightsabers," the co-author of a new study said. AdvertisementScientists have long believed that black holes, which generally swallow up everything around them, can also lose energy. Space.com noted that Albert Einstein's theory of relativity predicted that black holes can lose energy and scientists have believed since the 1970s that magnetic fields can extract energy from black holes.

CNN —The James Webb Space Telescope has looked into the heart of the Milky Way galaxy, unveiling new features and mysteries within the chaotic region that could help astronomers unravel more details about the early universe. Astronomers used Webb to glimpse Sagittarius C, or Sgr C, an active region of star formation located about 300 light-years from the galaxy’s central supermassive black hole Sagittarius A*. A light-year, equivalent to 5.88 trillion miles (9.46 trillion kilometers), is how far a beam of light travels in one year. Astronomers are still trying to determine what has created the vast amount of energized gas, which surpasses what would normally be released by young massive stars. “Webb has provided us with a ton of data on this extreme environment, and we are just starting to dig into it.”

☆ Gamma-ray burst in faraway galaxy disturbed Earth's upper atmosphere
▼ + stars: | 2023-11-14 | by ( Will Dunham | ) www.reuters.com time to read: +4 min

This gamma-ray burst, researchers said on Tuesday, caused a significant disturbance in Earth's ionosphere, a layer of the planet's upper atmosphere that contains electrically charged gases called plasma. It helps form the boundary between the vacuum of space and the lower atmosphere inhabited by people and Earth's other denizens. The gamma rays from the burst impacted Earth's atmosphere for a span of about 13 minutes on Oct. 9, 2022. Instruments on Earth showed that the gamma rays disturbed the ionosphere for several hours and even set off lightning detectors in India. The effects of this gamma-ray burst were studied with the help of the China Seismo-Electromagnetic Satellite (CSES), also called Zhangheng, a Chinese-Italian mission launched in 2018.

What Euclid’s first images revealEuclid focused on an array of targets for its first scientific images. While dark matter has never actually been detected, it is believed to make up 85% of the total matter in the universe. Both dark matter and dark energy also play a role in the distribution and movement of objects, such as galaxies and stars, across the cosmos. These observations will effectively allow Euclid to see how the universe has evolved over the past 10 billion years. “Euclid will make a leap in our understanding of the cosmos as a whole, and these exquisite Euclid images show that the mission is ready to help answer one of the greatest mysteries of modern physics,” said Carole Mundell, ESA Director of Science, in a statement.

Astronomers using data obtained by NASA's now-retired Kepler space telescope have identified seven planets orbiting a star in our Milky Way galaxy, with all of them suffering the wrath of their star - radiant energy - even more brutally than Mercury. This is the second-most planets so far discovered around any star beyond our solar system. All seven are larger than Earth, the biggest of our solar system's four rocky planets, but littler than Neptune, the smallest of our solar system's four gas planets. Scientists have to date identified more than 5,500 exoplanets - planets outside our solar system - and spotted hundreds of stars with multiple exoplanets. "The chance of life on any of these seven planets is indeed pretty remote," Lissauer said.

Trinity Site is the national historic landmark that’s home to mankind’s first nuclear blast on July 16, 1945, where plutonium gamma rays lit up the night sky. A caution sign warns of radioactive materials at Trinity Site in New Mexico back in 2008. The open house event, hosted by the US Army, is free but limited to the first 5,000 guests, on a first-come, first-served basis. Trinity Site’s atmosphere during an open house is reminiscent of a small-town carnival from a bygone era. And on April 6, 2024, Trinity Site again opens for a single day.

But they believe its clouds are metallic, a combination of titanium and silicate - the stuff that makes up most of the rocks in Earth's crust. "We even think that the clouds could condense into droplets, and have titanium rain falling in parts of the atmosphere," Jenkins said.

Unlocking what happened during the early days of the universe can help scientists tackle the biggest mysteries about its origin, how it evolved and what the future holds. “This expansion of space means that our observations of the early universe should appear to be much slower than time flows today. While very bright, supernovas become much harder to observe at greater distances from Earth, which means that astronomers needed another source that would be visible deeper in the early universe. “What we have done is unravel this firework display, showing that quasars, too, can be used as standard markers of time for the early universe.”
