☆ A Tantalizing ‘Hint’ That Astronomers Got Dark Energy All Wrong
▼ + stars: | 2024-04-04 | by ( Dennis Overbye | ) www.nytimes.com time to read: +1 min

Dark energy was assumed to be a constant force in the universe, both currently and throughout cosmic history. He shared the 2011 Nobel Prize in Physics with two other astronomers for the discovery of dark energy, but was not involved in this new study. “It may be the first real clue we have gotten about the nature of dark energy in 25 years,” he said. That conclusion, if confirmed, could liberate astronomers — and the rest of us — from a longstanding, grim prediction about the ultimate fate of the universe. Instead, it seems, dark energy is capable of changing course and pointing the cosmos toward a richer future.

▼ + stars: | 2024-02-01 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

CNN —The James Webb Space Telescope has captured scintillating portraits of 19 spiral galaxies — and the millions of stars that call them home — in unprecedented detail never seen before by astronomers. Astronomers believe that about 60% of all galaxies are spiral galaxies — and our solar system resides in one of the spiral arms of the Milky Way galaxy. Webb’s observations can help astronomers better understand star formation and the evolution of spiral galaxies like our own. The James Webb Space Telescope captured images of 19 spiral galaxies in near- and mid-infrared light. The images will be used to help astronomers determine the distribution of gas and dust in spiral galaxies, as well as how galaxies both nurture and cease the formation of stars.

CNN —A cosmic object in the shape of a glowing question mark has photobombed one of the latest images captured by NASA’s James Webb Space Telescope — and scientists think they know what it might be. The two have been observed and studied by space and ground-based telescopes since the 1950s, but the highly sensitive Webb telescope allowed for the highest-resolution and most detailed image yet. NASA/ESA/CSA/Joseph DePasquale (STScI)The Webb telescope illuminates information about the origins of our universe, but the appearance of this mysterious object in the background of this image leaves more questions than answers. The cosmic question mark hasn’t been closely observed or studied, so scientists aren’t exactly sure about the object’s origins and makeup. The question mark shape could also be “indicative of a merger where these two galaxies are interacting gravitationally,” Britt said.

The James Webb Space Telescope released a recent image that contains 45,000 galaxies. Scientists have been studying GOODS for years with various instruments, including the Hubble Space Telescope, Chandra X-ray Observatory, and Spitzer Space Telescope, to name just a few. James Webb Space Telescope discovers 100s of new galaxiesThe James Webb Space Telescope is studying the hearts of galaxies, like this one, to better understand star formation. With hundreds more galaxies to study in unprecedented detail, thanks to JWST, astronomers are learning that galaxies in our early universe were more turbulent than previously thought. In particular, by studying the light signatures of these young galaxies, astronomers spotted something they didn't expect: strong emission lines.

☆ NASA's James Webb Space Telescope is so powerful it discovered sand storms on a planet 235 trillion miles away
▼ + stars: | 2023-03-22 | by ( Grace Eliza Goodwin | Morgan Mcfall-Johnsen | ) www.businessinsider.com time to read: +4 min

NASA's James Webb Space Telescope found sand storms on a planet hundreds of trillions of miles away. From its vantage point in space, Webb can peer at a distant world and analyze the entire infrared spectrum of starlight passing through the planet's atmosphere. The James Webb Space Telescope fully deploys its primary mirror during development at Northrop Grumman Space Systems in Redondo Beach, California. The spectrum Webb found on the planet VHS 1256 b, showing signatures of silicate clouds, water, methane, and carbon monoxide. That means the stars' light doesn't drown out the light of the planet, making it an ideal target for the Webb telescope.

The first full-color image released from the next-generation James Webb Space Telescope is the sharpest infrared image of the distant universe ever produced, according to NASA. Space Telescope Science Institut / NASA, ESA, CSA, STScI, Webb ERONASA released the first batch of images from the tennis court-sized observatory to much fanfare in July.

CNN —The James Webb Space Telescope has captured a unique perspective of the universe, including never-before-seen galaxies that glitter like diamonds in the cosmos. “I was blown away by the first PEARLS images,” said study coauthor Rolf Jansen, research scientist at Arizona State University and a PEARLS coinvestigator, in a statement. Together, the wavelengths of light from both telescopes reveal unprecedented depth and detail of a wealth of galaxies in the universe. The image represents just a portion of the full PEARLS field, which will be about four times larger. Other pinpricks of light in the image represent a range of stars in our Milky Way galaxy.

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.

Astronomers took a new image of the Tarantula Nebula with the James Webb Space Telescope. Webb's instruments captured thousands of never-before-seen young stars, shrouded in cosmic dust. The space around the young stars is where gas has been cleared out by the stars' intense radiation and stellar winds. A side-by-side display of the same region of the Tarantula Nebula shows the difference between Webb's Near-Infrared Camera, left, and Webb's Mid-Infrared Instrument, right. Astronomers believe the Tarantula Nebula belongs to our universe's distant past.

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.
