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.

CNN —The beautiful chaos of two merging galaxies shines in the latest image captured by the James Webb Space Telescope. The Webb telescope, designed to observe faint, distant galaxies and other worlds, is an international mission between NASA and its partners, the European Space Agency and Canadian Space Agency. The pair of galaxies, known as II ZW 96, are located some 500 million light-years from Earth in the Delphinus constellation. Astronomers are using the observatory to study how galaxies evolve and, among other topics, why luminous infrared galaxies like II ZW 96 shine brightly in infrared light, reaching luminosities more than 100 billion times that of our sun. Researchers have turned Webb’s instruments on merging galaxies, including II ZW 96, to pick out fine details and compare the images with those previously taken by ground-based telescopes and the Hubble Space Telescope.

☆ AT 2022cmc: Rare cosmic event beamed light at Earth from 8.5 billion light-years away

But the rare cosmic event actually occurred 8.5 billion light years away from Earth, when the universe was just a third of its current age — and it has created more questions than answers. This graphic shows how a tidal disruption event might look in space. Carl Knox/OzGrav/Swinburne University of TechnologyWhen a star is torn apart by a black hole’s gravitational tidal forces, it’s known as a tidal disruption event. Observing more events like this could reveal how black holes launch such powerful jets across space, according to the researchers. “Scientists can use AT 2022cmc as a model for what to look for and find more disruptive events from distant black holes.”

CNN —The James Webb Space Telescope has captured a detailed molecular and chemical portrait of a faraway planet’s skies, scoring another first for the exoplanet science community. This “hot Saturn” was one of the first exoplanets that the Webb telescope examined when it first began its regular science operations. Bocaprins’ close proximity to its host star makes it an ideal subject for studying such star-planet connections. The planet is eight times closer to its host star than Mercury is to our sun. … We are already getting very exciting results,” Nestor Espinoza, an astronomer at the Space Telescope Science Institute, told CNN.

CNN —The James Webb Space Telescope has spied one of the earliest galaxies formed after the big bang, about 350 million years after the universe began. Webb’s capability to look deeper into the universe than other telescopes is revealing previously hidden aspects of the universe, including astonishingly distant galaxies such as these two finds. Two distant galaxies were observed by the James Webb Space Telescope. Just a few hundred million years after the big bang, there were already lots of galaxies. Detection of light invisible to the human eyeThe new findings about the two galaxies might mean there are other bright galaxies waiting to be found in the distant universe.

But as traders rushed to withdraw funds from FTX, Bankman-Fried was in denial and told investors he was convinced the business would be rescued, according to a source familiar with the situation. Bankman-Fried also quickly became one of the largest Democratic donors in the United States, contributing $5.2 million to President Joe Biden's 2020 campaign. He amassed a fortune, estimated as high as $26.5 billion by Forbes a year ago, by taking advantage of the price differences in bitcoin in Asia and the United States. Bankman-Fried eventually started crypto trading firm Alameda Research in 2017 and founded FTX a year later. "I thought we would fail," Bankman-Fried said at a June conference weeks before FTX and Alameda extended lifelines to two struggling crypto platforms.

NASA's Hubble Space Telescope captured a comet-like forked tail streaming from the asteroid Dimorphos. NASA's DART spacecraft slammed into the asteroid in September, as practice for saving Earth. In fact, it kind of looks like a comet now, NASA discovered when the Hubble Space Telescope snapped a new image of the distant space rock. So on September 26, the DART spacecraft slammed into Dimorphos, pushing it slightly closer to the larger asteroid it's orbiting, called Didymos. Telescopes across the planet and throughout Earth's orbit, including the new James Webb Space Telescope, are watching the asteroid closely.

David Grinspoon, an astrobiologist at the Planetary Science Institute, called the new Webb image “just spectacular beyond words.”“Oh. Young stars, estimated to be only a few hundred thousand years old, are the bright red orbs in the image. New stars form within clouds of dust and gas as dense clumps of mass collapse under their own gravity and begin to heat up. The Webb Telescope captured this dynamic journey in progress, according to Thomas Zurbuchen, the associate administrator of NASA's Science Mission Directorate. These are baby stars that are forming within the gas & dust," he tweeted.

A NASA spacecraft successfully changed an asteroid's orbit by intentionally smashing into it last month, agency officials confirmed Tuesday. The results of the cosmic collision are significant because it was the first real-life test of humanity's ability to protect the Earth from potentially catastrophic asteroids. "All of us have a responsibility to protect our home planet," NASA Administrator Bill Nelson said in a statement. NASA /ESA / STScI / HubbleThe DART mission (short for Double Asteroid Redirection Test) was a rare chance to test a key planetary defense strategy, offering scientists an opportunity to assess whether "nudging" an asteroid can actually change its orbit. "NASA has proven we are serious as a defender of the planet," Nelson said, adding that the mission was "a watershed moment for planetary defense and all of humanity."

☆ NASA, SpaceX to study boosting Hubble telescope to higher orbit
▼ + stars: | 2022-09-29 | by ( Jackie Wattles | ) edition.cnn.com time to read: +4 min

CNN —Officials at NASA have signed a Space Act Agreement with SpaceX to investigate the benefits and risks of having a private mission provide service to NASA’s nearly 33-year-old Hubble Space Telescope, boosting it to a higher orbit to extend its life, the space agency announced Thursday. Launched in 1990, the space observatory has had several servicing missions during NASA’s space shuttle era, with the last mission carried out in 2009. But the space agency retired the space shuttle in 2011, and no spacecraft has been back since. NASAThe effort to send a private mission to Hubble could be a part of a previously announced, privately funded SpaceX program called Polaris. Zurbuchen added that is all part of what SpaceX and NASA will explore as part of this Space Act Agreement.

That's when I started reporting on them, and like any good nerd I was compelled by what scientists could learn with these "brain computer interfaces." The race for implantable brain chips has been a long, deliberate marathon. Graham Felstead, who has severe paralysis, was the first person to have a BCI inserted via the blood vessels. Brain chips will enable them to perform simple actions on their own and reduce the need for round-the-clock care. "When we started in 2015 and I was pitching venture capitalists on brain computer interfaces, no one knew what a brain computer interface was," says Matt Angle, the CEO of Paradromics.

Lisa Kaltenegger, director of the Carl Sagan Institute at Cornell University, will be using the Webb telescope to do just that. The Webb telescope, a collaboration among NASA, the European Space Agency and the Canadian Space Agency, launched into space Dec. 25, 2021. The James Webb Space Telescope captured different wavelengths of light from an exoplanet known as WASP-96b, located more than 1,000 light-years away from Earth. Space Telescope Science Institute / NASA, ESA, CSA, and STScITelescopes like Webb can essentially peer back into the universe's history because it takes time for light to travel through space. Billed as the successor to the prolific Hubble Space Telescope, the Webb observatory is designed to study the earliest stars and galaxies in the universe.
