Astronomers find the longest jets ever from a faraway black hole.

Scientists found the longest jets ever seen coming from a black hole. These jets are like long streams of hot gas shooting out into space.

The jets are incredibly big, as long as 140 Milky Way galaxies lined up. This surprised scientists because they didn't expect to find jets this big so far away.

Black holes usually pull everything into them, but sometimes hot gas escapes. This gas forms jets that can be disrupted, but jets from supermassive black holes can grow very large.

These new jets are about 23 million light-years long, which is much longer than the previous record. To give you an idea, one light-year is about 5.8 trillion miles.

These jets are very old, dating back to when the universe was much younger. Scientists want to study them to learn more about how the early universe formed.
