Astronomers have observed a planet that in some ways behaves more like a star — including a massive growth spurt unlike anything witnessed before in a free-floating planet.

The rogue planet, which does not orbit any star, is called Cha 1107-7626 and is outside of our solar system, 620 light-years from Earth in the Chamaeleon constellation. A single light-year, or the distance light travels in one year, is equal to 5.88 trillion miles (9.46 trillion kilometers).

The planet has a mass five to 10 times that of Jupiter, the largest planet in our solar system. And it’s getting bigger every second, according to new research published Thursday in The Astrophysical Journal Letters.

Estimated to be 1 million to 2 million years old, Cha 1107-7626 is still forming, said study coauthor Aleks Scholz, an astronomer at the University of St. Andrews in Scotland. It may sound old, but astronomically speaking, the planet is in its infancy. By contrast, the planets in our solar system are about 4.5 billion years old.

Cha 1107-7626 is surrounded by a disk of gas and dust, which constantly falls onto the planet and accumulates during a process that astronomers call accretion. But the rate at which the young planet is growing varies, the study authors said.

Observations with the European Southern Observatory’s Very Large Telescope in Chile’s Atacama Desert, along with follow-up views conducted by the James Webb Space Telescope, showed that the planet is adding material about eight times faster than a few months earlier and gobbling up gas and dust at a record rate of 6.6 billion tons (6 billion metric tons) per second.

The unusual burst of activity is the strongest growth rate ever recorded for a planet of any kind, said lead study author Victor Almendros-Abad, an astronomer at the Palermo Astronomical Observatory of the National Institute for Astrophysics in Italy, and is shedding light on the tumultuous formation and evolution of planets.

“We’ve caught this newborn rogue planet in the act of gobbling up stuff at a furious pace,” said senior coauthor Ray Jayawardhana, provost and professor of physics and astronomy at Johns Hopkins University, in a statement.

“Monitoring its behavior over the past few months, with two of the most powerful telescopes on the ground and in space, we have captured a rare glimpse into the baby phase of isolated objects not much heftier than Jupiter. Their infancy appears to be much more tumultuous than we had realized.”

Astronomers first discovered Cha 1107-7626 in 2008, and since then, they have observed it with different telescopes to learn more about how the infant planet evolves, as well as to study its surroundings.

The research team observed the planet with Webb in 2024, making a clear detection of the surrounding disk. Next, the researchers studied it using the X-shooter spectrograph on the Very Large Telescope, which can capture different wavelengths of light emitted by an object ranging from ultraviolet to near-infrared.

The observations detected a puzzling event as the planet transitioned from a steady accretion rate in April and May to a burst of growth between June and August.

“I fully expected that this is a short-term event, because those are much more common,” Scholz said. “When the burst kept going through July and August, I was absolutely stunned.”

Follow-up observations made using the Webb telescope also showed that the chemistry of the disk had changed. Water vapor, present during the growth spurt, wasn’t in the disk before. Webb is the only telescope capable of capturing such detailed changes in the environment for such a faint object, Scholz said. Prior to this research, astronomers had only ever seen the chemistry of a disk change around a star, but not around a planet.

Comparing observations from before and during the event showed that magnetic activity seems to be the main driver behind how much gas and dust is falling on the planet — a phenomenon typically associated with stars as they grow.

But the new observations suggest that objects with much less mass than stars — the rogue world is less than 1% the mass of our sun — can have strong magnetic fields capable of driving the growth of the object, according to the study authors.

A planet that acts like a star
The origin of rogue planets remains murky. It’s possible they are planets that are kicked out of orbit around stars due to the gravitational influence of other objects. Or perhaps they are the lowest-mass objects that happen to form like stars. For Cha 1107-7626, astronomers said they think it’s the latter.

“This object most likely formed in a way similar to stars — from the collapse and fragmentation of a molecular cloud,” Scholz said.

A molecular cloud is a massive, cold cloud of gas and dust that can stretch for hundreds of light-years, according to NASA.

“We’re struck by quite how much the infancy of free-floating planetary-mass objects resembles that of stars like the Sun,” Jayawardhana said in a statement. “Our new findings underscore that similarity, and imply that some objects comparable to giant planets form the way stars do, from contracting clouds of gas and dust accompanied by disks of their own, and they go through growth episodes just like newborn stars.”

“The Russian war machine continues to destroy lives despite everything,” Zelensky said in a statement, hours before he’s due to meet US President Donald Trump in the Oval Office. “That is precisely why we are seeking assistance to put an end to the killings. That is why reliable security guarantees are required. That is why Russia should not be rewarded for its participation in this war.”

“Everyone seeks dignified peace and true security,” the Ukrainian president said. “And at this very moment, the Russians are attacking Kharkiv, Zaporizhzhia, the Sumy region, and Odesa, destroying residential buildings and our civilian infrastructure.”

At least seven people were killed in Russia’s attack? on Kharkiv and a further three killed in the ballistic missile strike on the city of Zaporizhzhia, with scores more injured, according to Ukrainian authorities.

“This was a demonstrative and cynical Russian strike,” Zelensky added.

Michelle Pfeiffer shares she’s now a grandmother
m bs2web at
Hollywood star Michelle Pfeiffer has announced that she has become a grandmother, and spoken about how it has affected her working life.

Speaking on the “Smartless” podcast on Monday, three-time Oscar nominee Pfeiffer told hosts Jason Bateman, Sean Hayes and Will Arnett that having a grandchild was “heaven.”

“I’ve been very quiet about it and it is – it’s heaven. It’s ridiculous,” said Pfeiffer, 67, who has an adopted daughter Claudia Rose and a son named John Henry.

“And if I had known that I was going to be a grandmother, I wouldn’t have taken on so much work, but I’ve enjoyed everything and I’m really grateful,” she said.

“I love each of these projects,” said Pfeiffer, referencing her recent work on projects including “Yellowstone” spin-off series “The Madison” on Paramount+, Christmas comedy “Oh. What. Fun” and the TV adaptation of Rufi Thorpe’s novel “Margo’s Got Money Troubles.”

“I’m so grateful. I’m so grateful because I love acting… in fact, I probably, enjoy it more now than I ever have because I’m sort of more relaxed with it,” said Pfeiffer.

The Hollywood star has had a long and storied career both in movies and on TV, including appearances in “Scarface” (1983), “Batman Returns” (1992) and Showtime series “The First Lady” (2022).

“I don’t really have time to be thinking about anything but the task at hand,” she said, highlighting the fact that she also set up a fragrance company a few years ago.

“But when I had all these acting jobs coming up, I thought, ‘Okay, okay, how are you going to manage this and have a life?’ Because that hasn’t always been easy for me. I’m an all or nothing kind of girl,” added Pfeiffer.

“I always like taking on challenges and then I get into it and it’s sort of sink or swim and for whatever reason I kind of feed on that,” she said, before going on to suggest that her priorities have shifted recently.

“I don’t have the time nor the desire to go that deep for that long and not be present,” said Pfeiffer.

Elusive shipwreck found in Lake Michigan over 100 years after sinking
рутор зеркало
A “ghost ship” that sank in Lake Michigan nearly 140 years ago and eluded several search efforts over the past five decades has been found, according to researchers with the Wisconsin Underwater Archeology Association.

The wooden schooner got caught in a storm in the dead of night and went down in September 1886. In the weeks after, a lighthouse keeper reported the ship’s masts breaking the lake surface, and fishermen caught pieces of the vessel in their nets. Still, wreck hunters were unable to track down the ship’s location — until now.

Earlier this year, a team of researchers with the Wisconsin Underwater Archeology Association and Wisconsin Historical Society located the shipwreck off the coastal town of Baileys Harbor, Wisconsin, the association announced on Sunday.

Named the F.J. King, the ship had become a legend within the Wisconsin wreck hunter community for its elusive nature, said maritime historian Brendon Baillod, principal investigator and project lead of the discovery.

“We really wanted to solve this mystery, and we didn’t expect to,” Baillod told CNN. “(The ship) seemed to have just vanished into thin air. … I actually couldn’t believe we found it.”

The wreck is just one of many that have been found in the Great Lakes in recent years, and there are still hundreds left to be recovered in Lake Michigan alone, according to Baillod.

The ‘ghost ship’
Built in 1867, the F.J. King plied the waters of the Great Lakes for the purpose of trans-lake commerce. The ship transported grains during a time when Wisconsin served as the breadbasket of the United States. The 144-foot-long (44-meter) vessel also carried cargo including iron ore, lumber and more.

The ship had a lucrative 19-year career until that September night when a gale-force wind caused its seams to break apart, according to the announcement. The captain, William Griffin, ordered the crew to evacuate on the ship’s yawl boat, from where they watched the F.J. King sink, bow first.
