The technological feat, using NASA's Psyche probe, broke new ground for deep space communications. AdvertisementNASA has achieved a world-first after sending a laser-beamed message to Earth from nearly 10 million miles away within 50 seconds. While the space agency has long been able to communicate with spacecraft using radio waves, it had never before been able to send information using lasers from that far into space. The feat, achieved using NASA's Deep Space Optical Communications (DSOC) experiment on board the Psyche spacecraft, could someday allow humans to stream video calls on Mars. The spacecraft then beamed back information using its laser.

But Webb has obtained even better data on galaxies a bit further along in development. The gas detected in star-forming regions - stellar nurseries - of teenage galaxies was much hotter, at about 24,000 degrees Fahrenheit (13,350 degrees Celsius), than observed in galaxies today. The galaxies were observed glowing with eight elements - hydrogen, helium, oxygen, nitrogen, sulfur, argon, nickel and silicon. Incidentally, oxygen is also the third-most abundant element in the universe (behind hydrogen and helium)," Strom said. The new study presents the first results from the CECILIA Survey that uses Webb to scrutinize the chemistry of distant galaxies.

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.”

Planets beyond our solar system have a size gap, where worlds seem to shrink past a certain range. Scientists think this is because some sub-Neptunes shrink — losing their atmospheres and speeding through the size gap until they are as small as a super-Earth. AdvertisementThe planets themselves may be pushing their atmospheres awayShrinking exoplanets may lack the mass (and therefore the gravity) to hold their atmospheres close. AdvertisementThe other hypothesis, called photoevaporation, says that a planet's atmosphere is dissipated by the radiation of its host star. AdvertisementThe scientists found that most of the planets there retained their atmosphere, making the core-powered mass loss a more likely cause of eventual atmosphere loss.

CNN —Space is full of extreme phenomena, but the “Tasmanian devil” may be one of the weirdest and rarest cosmic events ever observed. Astronomers dubbed the celestial object the “Tasmanian devil,” and they observed it exploding repeatedly following its initial detection in September 2022. But the Tasmanian devil is revealing more questions than answers with its unexpected behavior. While LFBOTs are unusual events, the Tasmanian devil is even stranger, causing astronomers to question the processes behind the repetitive explosions.

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.

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.

Data from NASA's Magellan spacecraft and Pioneer Venus Orbiter is used in an undated composite image of the planet Venus. Its thick and noxious atmosphere is dominated by carbon dioxide - 96.5% - with lesser amounts of nitrogen and trace gases. In fact, with Venus getting far less scientific attention than other planets such as Mars, the direct detection of its oxygen has remained difficult. They noted that this atomic oxygen, which consists of a single oxygen atom, differs from molecular oxygen, which consists of two oxygen atoms and is breathable. "The Venus atmosphere is very dense.

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.

CAPE CANAVERAL, Fla. (AP) — Scientists on Tuesday unveiled the first pictures taken by the European space telescope Euclid, a shimmering and stunning collection of galaxies too numerous to count. The photos were revealed by the European Space Agency, four months after the telescope launched from Cape Canaveral. Although these celestial landscapes have been observed before by the Hubble Space Telescope and others, Euclid's snapshots provide "razor-sharp astronomical images across such a large patch of the sky, and looking so far into the distant universe," the agency said. In one picture, Euclid captured a group shot of 1,000 galaxies in a cluster 240 million light-years away, against a backdrop of more than 100,000 galaxies billions of light-years away. Although the Hubble Space Telescope previously observed the heart of this galaxy, Euclid’s shot reveals star formation across the entire region, scientists 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.

"The rest of the universe we call dark because it doesn't produce light in the normal electromagnetic spectrum.

Lick Observatory and Lowell Observatory in Flagstaff, Ariz., which opened in 1894, both remain active in astronomical research. Other historic observatories now focus primarily on public outreach and education, including Yerkes Observatory (1897) in Williams Bay, Wis., and Mount Wilson Observatory (1904), outside Pasadena, Calif. At each of these sites, you can step into the history of the cosmos — experiencing the deep time of the stars, as well as more recent histories of discovery. Looking through 19th-century glass at the Lick, you can see where E. E. Barnard spotted a new moon of Jupiter and James Keeler found a gap in Saturn’s rings. At Mount Wilson, Edwin Hubble, building on work done by Henrietta Swan Leavitt at Harvard, made an observation that proved there were other galaxies in the universe beyond the Milky Way. At Yerkes, you can peer through the 40-inch refracting telescope that surpassed Lick’s in size in 1897 and was used by a cadre of path-breaking women working in astronomy.
