☆ Ancient galaxy reveals a surprising way to annihilate a star
▼ + stars: | 2023-06-22 | by ( Ashley Strickland | ) edition.cnn.com time to read: +6 min

The explosion lasted just over a minute — considered long, like any gamma-ray burst, or GRB, that lasts more than two seconds. These violent, destructive bursts can leave behind dense remnants like neutron stars or result in the creation of black holes. Why ancient galaxies could hide star deathsDuring their search for the origin of the gamma-ray burst, astronomers used the Gemini South telescope located in Chile to observe the afterglow of the cosmic explosion. Compared with younger, more typical galaxies, ancient galaxies can have up to a million or more stars densely packed into their cores. But they had no evidence for any long gamma-ray bursts originating from ancient galaxies — until now.

☆ Astronomers discover the fastest runaway stars in our galaxy racing away at over 5 million mph

Astronomers found two renegades, runaway white dwarf stars on an escape route out of our galaxy. These runaway stars are on a one-way ticket out of our galaxy. Runaway stars racing away at breakneck speedsIn the new study, astronomers using data from the European Space Agency's Gaia survey identified two runaway stars with the fastest radial velocities ever seen. Two white dwarf stars orbiting each other can trigger an especially enormous explosion called a D^6 supernova. The first explosion kicks off when one of the white dwarf stars accumulates too much helium gas, which triggers a thermonuclear explosion, reported Starr.

A supernova has exploded in the Pinwheel Galaxy 21 million light-years away. Named SN 2023ixf, it sets itself apart by being one of the brightest seen in a decade. The supernova, which appeared in the Pinwheel Galaxy 21 million light-years away, is one of the biggest and brightest in our skies in a decade, Space.com reported. But this supernova, named SN 2023ixf, sets itself apart by its proximity to Earth: it's located in the Pinwheel Galaxy, which is only about 21 million light-years away. The Pinwheel Galaxy is located close to two of the stars in the handle of the Big Dipper.

CNN —A sparkling new supernova has appeared in the night sky, and a telescope atop Mauna Kea in Hawaii was perfectly poised to capture the aftermath of the cosmic burst. The supernova was first spotted within the spiral arms of the Pinwheel Galaxy by Japanese astronomer Koichi Itagaki on May 19. The Pinwheel Galaxy is in the direction of the Ursa Major constellation, about 21 million light-years from Earth. The new supernova glimmers bright blue in one of the galaxy’s spiral arms in the bottom left of the image. It’s the second supernova observed in the Pinwheel Galaxy in 15 years.

This dying red giant had only recently mysteriously dimmed its shine after an enormous explosion. It is expected to explode into a supernova visible from Earth, though likely not for thousands of years. The red giant — a star not far from death — is now shining about 50% brighter than it usually would, scientists said. Scientists are keeping a close eye on Betelgeuse, as this red giant is a dying star that is close to turning supernova. Betelgeuse could burst into a supernova visible from Earth — one dayA pre-supernova star, called a Wolf-Rayet star, 15,000 light-years away in the constellation Sagittarius.

Consumer stocks Constellation Brands (STZ) and Procter & Gamble (PG) were the subjects of Wall Street scrutiny Thursday. Analysts are concerned about the stock's valuation and the risk to the company's volumes as P & G raises prices on its products. If uncertainty over the health of U.S. banks persists, analysts believe, P & G stock will "likely hold up." But they added, "If the issue dies down, we expect investors to move into less risk-averse stocks." Truist also thinks "investors may be overreading" the consumer goods giant's better-than-expected fiscal third quarter in April.

Right now, the explosion is so bright that it's not possible to see a galaxy around the black hole.

☆ Webb telescope captures glowing starburst as galaxies collide

CNN —A brilliant starburst feature shines in the latest image taken by the James Webb Space Telescope. The space observatory captured a bright burst of star formation triggered by two spiral galaxies crashing into one another. The colliding galaxies, known collectively as Arp 220, generated an infrared glow that contains the light of more than 1 trillion suns. This brilliant luminosity creates the diffraction spikes, or starburst feature witnessed by Webb. The new Webb image also reveals tails, or material streaming away from the galaxies due to gravity, in blue, to indicate activity as the galaxies continue to collide.

Our solar system was hit by a gamma-ray burst so bright, it blinded space equipment and telescopes. A gamma-ray burst that recently hit our solar system was so bright, it temporarily blinded gamma-ray instruments in space, according to a NASA release. Scientists say the gamma-ray burst (GRB), the most powerful type of explosion in the universe, was 70 times brighter than any previously recorded event. What is a gamma-ray burst? Because it blinded space instruments, they couldn't accurately record it, so scientists weren't sure how bright the burst was when it first reached our planet.

Extraterrestrial life could exist, but mysterious objects in the sky aren't evidence of aliens. Scientists have thought they were close to discovering alien life a few times — none of it via UFOs. As the US discovered a flurry of UFOs — officially called "unidentified anomalous phenomena," or UAPs — in early February, Google searches for "extraterrestrial life" and "are aliens real" spiked. There have been incidents in the past where some researchers thought they'd come close to discovering signs of alien life — or even extraterrestrial intelligence — but none were UFOs. They dubbed the first interstellar object 'Oumuamua, which is a Hawaiian term meaning "a messenger from afar arriving first."

This binary system, studied using a telescope at the Chile-based Cerro Tololo Inter-American Observatory, is located about 11,000 light years from Earth in our Milky Way galaxy in the direction of the constellation Puppis. Its companion star boasts a mass 18 to 19 times greater than the sun after cannibalizing its mate. The two stars orbit around each other every 59-1/2 days, separated by about eight-tenths of the distance existing between Earth and the sun. The type of binary system examined in this study is rare, with roughly 10 estimated to exist in a Milky Way populated by about 100-400 billion stars.

The gamma-ray burst, called GRB 211211A, lasted about a minute. Gamma-ray bursts are considered among the strongest and brightest explosions in the universe, and they can range from a few milliseconds to several hours in length. An artist's illustration of GRB 211211A shows the kilonova and gamma-ray burst (right) and ejected material from the explosion (left). After determining that a kilonova created the infrared light, astronomers grew even more puzzled by the gamma-ray burst’s duration. Gamma-ray bursts caused by these rare explosions have only ever been observed to last less than two seconds, but this signal lasted for at least one minute.

Editor’s Note: The following contains spoilers about “The Walking Dead” series finale, “Rest in Peace,” which premiered November 20. CNN —Forgive AMC, at least a little bit, for almost drunkenly celebrating “The Walking Dead” in its heyday by feeding audiences as much content related to the zombie drama as they possibly could. In its early seasons, “The Walking Dead” excelled in part because of its unpredictability, as the montage of characters who had died reminded the audience. Those plans later morphed into a limited series, but the sense that “The Walking Dead” was no longer the priority in AMC’s “Dead” universe had been pretty well cemented. Television is always hungry for another hit, and at its height “The Walking Dead” was the TV equivalent of a supernova.

But not before Johnson prompts his co-star to say something “sexy” into the camera and Evans obliges.
