Editor’s note: A version of this story appeared in CNN’s Wonder Theory science newsletter. Analysis of ancient DNA recovered from human remains has illuminated the traits and ancestry of historic individuals — be it a mummified iceman, Chinese emperor or legendary composer. The origins of the empire and its people remained obscure until a landmark April 2022 study found they hailed from the Mongolian steppe. Carolyn Kaster/APNaturalists have spotted the first arrivals in this spring’s historic cicada dual emergence.

☆ Hubble image may contain evidence of stellar cannibalism in dumbbell-shaped nebula

The nebula, 3,400 light-years away in the Perseus constellation, is an expanding shell of gases kicked out by a dying red giant star. Before the aging red giant star collapsed, it released a ring of gas and dust. The companion star, once in orbit around the red giant, is nowhere to be seen in Hubble’s image. Since collapsing, the red giant star has transformed into a dead stellar remnant known as an ultra-dense white dwarf star. “The space telescope is the most scientifically productive space astrophysics mission in NASA history,” according to a NASA release.

Observations from the European Space Agency’s Cheops space telescope, or Characterising ExOplanet Satellite, detected a “glory effect” on WASP-76b, an ultra-hot exoplanet 637 light-years from Earth. Cheops captured data from WASP-76b as the planet passed in front of its star, making 23 observations over three years. But the glory effect is created as light moves through a narrow opening and bends, creating colorful, patterned rings. An artist's illustration shows the night-side view of the exoplanet WASP-76b, where iron rains down from the sky. Lueftinger said she believes that the James Webb Space Telescope or Ariel may be able to help prove the presence of the glory effect on WASP-76b.

☆ Universe’s brightest known object and fastest-growing black hole revealed
▼ + stars: | 2024-02-21 | by ( Ashley Strickland | ) edition.cnn.com time to read: +6 min

CNN —Astronomers have spotted the brightest known object in the universe, and it’s a quasar powered by the fastest-growing black hole on record, according to a new study. The black hole powering the quasar devours the equivalent of one sun per day and has a mass about 17 billion times that of our sun, the researchers found. A black hole is massive power sourceThe intense gravitational influence of black holes draws matter toward these celestial objects in such an energetic way that the process creates light. The blinding radiation is due to the black hole’s accretion disk, or the ring around the black hole where material gathers before being consumed. The team followed up with observations from the powerful Very Large Telescope in Chile’s Atacama Desert to confirm details about the black hole, including its hefty mass.

☆ Webb telescope spies millions of stars in stunning spiral galaxies

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 —Astronomers using the Hubble Space Telescope have detected water molecules in the atmosphere of a small, blazing-hot exoplanet 97 light-years from Earth. The planet, named GJ 9827d, is about twice Earth’s diameter, and it’s the smallest exoplanet found to have water vapor in its atmosphere, according to a new study. Starlight filtering through the planet’s atmosphere helped astronomers measure the signature of water molecules. It’s possible that the planet is a mini-Neptune with a hydrogen-rich atmosphere that contains water vapor. Or astronomers suspect that GJ 9827d could be a warmer version of Jupiter’s icy moon Europa, which contains an ocean beneath a thick, icy crust.

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.

Hubble has long been used to search for faint, distant galaxies across different wavelengths of light.

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.

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.

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.
