Scientists have discovered the longest pair of jets streaming from a black hole in a distant galaxy.
The jets shooting hot plasma are the largest ever spotted – about as long as 140 Milky Way galaxies lined up end-to-end.
“This one has managed to reach a size that’s so big,” said Eileen Meyer, who studies black holes at University of Maryland, Baltimore County and who was not involved in the study.
The discovery, made using images from a European radio telescope, was reported Wednesday in the journal Nature, The Associated Press said.
Black holes eat most space debris that falls their way. Sometimes, heated-up plasma makes a narrow escape by spewing out in thin, high-energy jets.
The jets can break apart soon after their creation, jostled by space turbulence or starved in the absence of new matter. But jets from supermassive black holes can become supersized.
The latest combined jets from a faraway supermassive black hole are around 23 million light-years long. That’s about 7 million light-years longer than the previous recordholder. A light-year is 5.8 trillion miles.
Study co-author Martijn Oei said researchers weren’t expecting to find long black hole jets so early in the universe’s history. The jets date back to when the universe was less than half its current age.
Studying the jets could reveal whether they had an influence on how the early universe came to be, said Oei with the California Institute of Technology.

An uncontained bushfire raging in Australia's Victoria state that has prompted an evacuation order for hundreds of residents will burn for several days, officials said on Sunday.

The order to leave immediately, set at the highest danger rating, remained in place for the fire in and around Grampians National Park, about 241 km (149 miles) west of state capital Melbourne, Victoria's emergency services agency said on its website.

"There's a lot of unburnt fuel in the Grampians still, so it's quite a challenge for the days ahead", Country Fire Authority deputy chief officer Garry Cook told the Australian Broadcasting Corporation, referring to the fire that now covered 34,000 hectares (84,000 acres) of bush.

The blaze, sparked on Tuesday by lightning, prompted authorities on Saturday to urge residents of several rural towns such as Halls Gap, population 495, to evacuate.

Hundreds of firefighters have battled the bushfire, using more than 100 tankers and 25 aircraft, ABC reported on Saturday.

Authorities have warned of a high-risk bushfire season this Australian summer after several quiet seasons. The 2019-2020 "Black Summer" fires destroyed an area the size of Türkiye and killed 33 people.
