Astronomers just found something that doesn’t fit any category we have: a “black hole star.”

Using the James Webb Space Telescope, an MIT-led team spotted a very bright red dot from the early universe, just a few hundred million years after the Big Bang. At first glance it looks like a gigantic star, about the size of our entire solar system. But it’s putting out 100 billion times more energy than any star can produce, which is much closer to what a black hole does.

The best explanation is a mashup of both. At the center sits a black hole about 100,000 times the mass of our sun, wrapped in a thick cocoon of hydrogen gas. The black hole acts as the power source, while the gas glows like the surface of a star.

This could solve a bigger mystery too. Webb keeps finding these “little red dots” all over the early universe, and nobody has been sure what they are. Researchers now suspect many of them could be black hole stars as well.

The team wasn’t even looking for this. They were hunting for the earliest galaxies when one strange dot stood out. As lead author Rohan Naidu put it, what looks like a bright young galaxy can sometimes turn out to be a mirage.

Something hit the Mediterranean Sea in 2023, and scientists still can’t say where it came from.

It was a tiny particle called a neutrino, and it carried about 30 times more energy than any neutrino we’ve ever measured. Neutrinos are so lightweight and slippery that they pass through almost everything, which is why detecting one at all is a big deal. This one was caught by a huge underwater detector sitting more than 3 kilometers deep off the coast of Sicily.

So where did it come from? Scientists have a few guesses. The most likely is a distant galaxy shooting a powerful beam of energy in our direction. Other ideas include mysterious dark matter or exploding miniature black holes. One wild theory even involves a hidden extra dimension, though there’s no evidence for that yet.

The catch is that nobody has been able to match it to a source, and another major detector in Antarctica didn’t see anything similar. One detection raises the question, but it will take more of them to answer it.

If scientists finally solve this mystery, what are you hoping the answer turns out to be? 🌌

US officials accused Russia at the UN of a "deliberately reckless" move after its Kosmos-2612 satellite came within an estimated 200 meters of ICEYE-X36, a commercial radar satellite that supplies imagery to Ukraine. #Russia #Space #Ukraine

SpaceX's Starship reached orbit for the first time on its 14th test flight, despite losing one of six upper-stage engines. The vehicle also deployed 26 Starlink V3 satellites after reaching orbital velocity. #SpaceX #Starship #Starlink #Space
