☆ Webb telescope reveals new details in Milky Way’s heart
▼ + stars: | 2023-11-20 | by ( Ashley Strickland | ) edition.cnn.com time to read: +3 min

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.”

CNN —Astronomers have spied an intriguing phenomenon in the distant universe — a galaxy that closely resembles the Milky Way — and it’s challenging key theories on how galaxies evolve. Like our home galaxy, the newly discovered ceers-2112 is a barred spiral galaxy, and it’s now the most distant of its kind ever observed. While massive spiral galaxies are common in the Milky Way’s cosmic neighborhood, that hasn’t always been the case. The bars take shape when stars within spiral galaxies rotate in an orderly fashion, as they do in the Milky Way. “The discovery of ceers-2112 paves the way for more bars to be discovered in the young universe,” de la Vega said.

The galaxy, named ceers-2112, is more than 11.7 billion years old and is the earliest example of a barred spiral galaxy ever seen. For them, there is little doubt: this picture suggests this is a barred spiral galaxy. Scientists had thought you couldn't find a barred spiral galaxy before the universe was about 6.9 billion years old. The other 95% — about 27% of dark matter and 68% of dark energy — remain huge mysteries in physics.

New details of the celestial feature have emerged in the colorful image, which unites the observational powers of Hubble Space Telescope in visible light and the James Webb Space Telescope in infrared light, which is invisible to the human eye. Hubble has long been used to search for faint, distant galaxies across different wavelengths of light. This cosmic effect occurs when closer objects — such as the galactic clusters — act like a magnifying glass for distant objects. The Webb and Hubble composite image includes "Mothra," a star system magnified by the galactic cluster pair as well as another unseen object. NASA/ESA/CSA/STScIThe team nicknamed the star system Mothra due to its extreme magnification and brightness.

PARIS, Nov 7 (Reuters) - European astronomers on Tuesday released the first images from the newly launched Euclid space telescope, designed to unlock the secrets of dark matter and dark energy - hidden forces thought to make up 95% of the universe. Scientists believe vast, seemingly organised structures such as Perseus could only have formed if dark matter exists. "The rest of the universe we call dark because it doesn't produce light in the normal electromagnetic spectrum. Tell-tale signs of the hidden force exerted by dark matter include galaxies rotating more quickly than scientists would expect from the amount of visible matter that can be detected. We think there's lots of dark matter in that cluster and pulling these galaxies together," she added.

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.

CNN —Two powerful NASA telescopes have detected the oldest and most distant black hole ever found. “We needed Webb to find this remarkably distant galaxy and Chandra to find its supermassive black hole,” said lead study author Akos Bogdan, in a statement. Potential black hole theoryTypically, black holes located at the centers of galaxies only have about 0.1% the mass of the stars within their host galaxy. The unusual black hole could be an “Outsize Black Hole” that formed when a huge cloud of gas collapsed, as theorized in 2017 by Priyamvada Natarajan, a coauthor on both studies and the Joseph S. and Sophia S. Fruton professor of astronomy and professor of physics at Yale University in New Haven, Connecticut. “We think that this is the first detection of an ‘Outsize Black Hole’ and the best evidence yet obtained that some black holes form from massive clouds of gas,” Natarajan said.

“And it’s those ingredients pulled together that is going to make Euclid the iconic cosmology mission of the day.”Whereas NASA’s James Webb Space Telescope zooms in on one part of the sky at a time, Euclid excels at imaging wide, but still detailed, swaths of the universe. That’s perfect for “when you want to look for a needle in a haystack,” Dr. Seiffert said, including objects like free-floating worlds. With the data Euclid sends home, researchers can learn about how the web of dark matter cementing our universe together influences the shapes and motions of visible objects in space. The telescope’s detailed resolution is also expected to help scientists map the distribution of galaxies across cosmic time, aiding in understanding dark energy, the inexplicable force pulling the universe apart. Over the summer, scientists worked around the clock to fix a faulty navigation sensor that made Euclid create images of winding star trails as the telescope tried to capture a piece of sky.

CAPE CANAVERAL, Fla. (AP) — Scientists have discovered the oldest black hole yet, formed a mere 470 million years after the Big Bang. The findings, published Monday, confirm what until now were theories that supermassive black holes existed at the dawn of the universe. Given the universe is 13.7 billion years old, that puts the age of this black hole at 13.2 billion years. Even more astounding to scientists, this black hole is a whopper — 10 times bigger than the black hole in our own Milky Way. That is nowhere near the miniscule ratio of the black holes in our Milky Way and other nearby galaxies, scientists said.

The astronomers spied a high-speed jet stream in Jupiter’s lower stratosphere, an atmospheric layer about 25 miles (40 kilometers) above the clouds. “What we have always seen as blurred hazes in Jupiter’s atmosphere now appear as crisp features that we can track along with the planet’s fast rotation,” he said. Jet stream revelationsResearchers compared winds detected by Webb at high altitudes with those within the lower layers picked up by Hubble and tracked changes in wind speed. Both space observatories were necessary to detect the jet stream, as Webb spotted small cloud features and Hubble provided a look at the equatorial atmosphere, including storms not related to the jet. Future observations of Jupiter using the Webb telescope may uncover more insights into the jet stream, such as whether its speed and altitude shift over time, as well as other surprises.

Star formation in the early galaxies occurred in occasional big bursts, they found, rather than at a steady pace. "According to the standard model of cosmology, there should not be many very massive galaxies during cosmic dawn because it takes time for galaxies to grow after the Big Bang. And the reason this is so significant is that we explain these very bright galaxies without having to break the standard cosmological model," Faucher-Giguère added. They blast gas into space that becomes ingredients for another burst of star formation. But the stronger gravitational effects in larger galaxies prevent these bursts, favoring steady star formation.
