▼ + stars: | 2023-06-06 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

CNN —Astronomers have detected the most distant known organic molecules in the universe using the James Webb Space Telescope. It’s the first time Webb has detected complex molecules in the distant universe. The complex molecules were found in a galaxy known as SPT0418-47, located more than 12 billion light-years away. The galaxy observed by the Webb telescope shows an Einstein ring caused by a phenomenon known as gravitational lensing, which occurs when two galaxies are almost perfectly aligned from our perspective on Earth. Investigating the early universeAstronomers spotted the signature of the organic molecules during a careful analysis of Webb’s data.

OpenAI is taking up the mantle against AI "hallucinations," the company announced Wednesday, with a newer method for training artificial intelligence models. To date, Microsoft has invested more than $13 billion in OpenAI, and the startup's value has reached roughly $29 billion. AI hallucinations occur when models like OpenAI's ChatGPT or Google 's Bard fabricate information entirely, behaving as if they are spouting facts. OpenAI's potential new strategy for fighting the fabrications: Train AI models to reward themselves for each individual, correct step of reasoning when they're arriving at an answer, instead of just rewarding a correct final conclusion. OpenAI has released an accompanying dataset of 800,000 human labels it used to train the model mentioned in the research paper, Cobbe said.

☆ NASA released stunning new space images by combining the visual powers of the James Webb Space Telescope and Chandra X-ray Observatory
▼ + stars: | 2023-05-29 | by ( Jacob Zinkula | ) www.businessinsider.com time to read: +4 min

The images were enhanced using data from the James Webb Space Telescope and the Chandra X-ray Observatory. The images were made possible by data collected from the Chandra X-Ray Observatory, the James Webb Space Telescope, and the Hubble Space Telescope. "The Chandra data also reveal young, hot, and massive stars that send powerful winds outward from their surfaces," NASA said. The beautiful spiral galaxy NGC 1672 shows off its black holes and neutron starsNGC 1672 is a spiral galaxy about 60 million light-years from Earth. "Webb outlines gas and dust in the infrared while Chandra data spotlights high-energy activity from stars at X-ray wavelengths," NASA said.

The James Webb Space Telescope, the most powerful ever made, has revolutionized the way we see the universe. The name was chosen for James E. Webb, a NASA administrator during the 1960s. But when doubts about his background emerged, the telescope’s name turned into a fight over homophobia. Michael Powell, a national reporter for The Times, tells the story of Dr. Hakeem Oluseyi, an astrophysicist whose quest to end the controversy with indisputable facts only made it worse.

☆ Earth-size exoplanet may be covered in volcanoes
▼ + stars: | 2023-05-17 | by ( Ashley Strickland | ) edition.cnn.com time to read: +6 min

Instead, the exoplanet, called LP 791-18 d, is likely covered in volcanoes and may experience eruptions with the same frequency as Jupiter’s moon Io, the most volcanically active place in our solar system, according to researchers. LP 791-18 d is located about 90 light-years from Earth in the Crater constellation, where it orbits a small red dwarf star. And astronomers believe the massive planet LP 971-18 c might be contributing to the newly detected exoplanet’s possible volcanism. As the two objects orbit their star, LP 971-18 c and the newfound exoplanet LP 791-18 d closely pass each other, allowing the gravitational pull of the larger planet LP 971-18 c to tug on planet d and reshape its orbit. The discovery of LP 971-18 d points to the importance of data collected by space telescopes.

☆ Webb telescope spots water in rare comet
▼ + stars: | 2023-05-15 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

CNN —Astronomers used the James Webb Space Telescope to observe a rare comet in our solar system, making a long-awaited scientific breakthrough and stumbling across another mystery at the same time. For the first time, water was detected in a main belt comet, or a comet located in the main asteroid belt between the orbits of Mars and Jupiter. The space observatory detected water vapor around Comet Read, which suggests that water ice can be preserved in a warmer part of the solar system. It’s possible that the warmer temperatures of the main asteroid belt cause Comet Read to lose its carbon dioxide over time, the researchers said. Comet Read might have also formed in a warmer pocket of the solar system without carbon dioxide, Kelley said.

☆ Webb telescope spies evidence of hidden planets around nearby star
▼ + stars: | 2023-05-08 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

The revelation of the Fomalhaut’s two inner rings has suggested that planets hidden deeper within the star system may be affecting the dust belt’s shape. Stars form from gas and dust, and then a ring of leftover material called a protoplanetary disk orbits the star, where planets are born. Once the planets form around a star, debris belts form and become shaped by the gravity of the planets. Studying the dust belts can help unlock more of the secrets behind how planetary systems form. “I think it’s not a very big leap to say there’s probably a really interesting planetary system around the star.”

Fomalhaut, a star just 25 light-years away, is so dazzlingly bright that it blots out the faint light of other stars around it. Stargazers have been enraptured by its secrets for thousands of years. Now, with the help of the James Webb Space Telescope, astronomers have documented evidence that Fomalhaut is a dynamic star wreathed in cosmic chaos. The powerful observatory’s infrared vision is letting astronomers better understand Fomalhaut’s features, including a mysterious ring unlike anything found in our solar system. “It’s the first time we’ve seen such structures in an evolved system.”The findings could contribute to the solution to an existential puzzle: How weird, or ordinary, is our solar system?

CNN —The James Webb Space Telescope has detected water vapor around a rocky exoplanet that orbits a star located 26 light-years away from Earth. The presence of water vapor could suggest that GJ 486 b somehow has an atmosphere, despite its heat and proximity to the star. “Water vapor in an atmosphere on a hot rocky planet would represent a major breakthrough for exoplanet science. The results from the Webb data analysis pointed to water vapor being present around GJ 486 b. Future observations of the planet using different instruments on the Webb telescope could reveal additional details about the source of the water vapor.

Like basketball scouts discovering a nimble, super-tall teenager, astronomers using the James Webb Space Telescope reported recently that they had identified a small, captivating group of baby galaxies near the dawn of time. These galaxies, the scientists say, could well grow into one of the biggest conglomerations of mass in the universe, a vast cluster of thousands of galaxies and trillions of stars. The seven galaxies they identified date to a moment 13 billion years ago, just 650 million years after the Big Bang. He described the proto-cluster as the most distant and thus earliest such entity yet observed. Dr. Morishita was the lead author of a report on the discovery, which was published on Monday in The Astrophysical Journal Letters.

CNN —Astronomers first discovered quasars, considered to be the brightest and most powerful objects in the universe, 60 years ago — but they didn’t understand their origin. Now, scientists think they have unlocked the mystery behind what ignites these celestial objects. Astronomers observed 48 different galaxies that contain quasars and compared them to more than 100 galaxies without them. When two galaxies merge, massive amounts of gas are pushed toward the supermassive black holes located at their centers. “Quasars play a key role in our understanding of the history of the Universe, and possibly also the future of the Milky Way.”

CNN —Rocket launches are like opening a box of chocolates, only riskier — you never know what you’re going to get. When a rocket is set to leap off the launchpad, there’s a good chance of seeing a stunning liftoff or a spectacular failure. The lead-up to this week’s launch of SpaceX’s Starship, the most powerful rocket ever built, was a dramatic roller coaster. The rocket blasted off from the launchpad in South Texas and roared 24.2 miles (39 kilometers) over the Gulf of Mexico. Now, researchers have a new theory about why the Vikings abruptly departed in the mid-15th century: rising sea levels.

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.

The discovery is another example of how observations by Webb, which was launched in 2021 and began collecting data last year, are transforming our knowledge of the nature of the early universe. The orbiting infrared observatory was designed to be far more sensitive than its Hubble Space Telescope predecessor. This galaxy, Kelly said, is "absolutely tiny" in relative terms. "Nonetheless, we found that it was forming about two stars each year, which is similar to the rate at which the Milky Way is forming stars," Kelly added. "The combined power of the James Webb Space Telescope and the galaxy's magnification due to gravitational lensing allows us to study this galaxy in detail," Williams said.

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.
