Astronomers announced Wednesday they had discovered a new type of astronomical object called a “black hole star,” potentially solving a mystery involving strange red dots spotted in the early universe. The object looks like a star the size of our solar system, but produces 100 billion times more energy than any star — a mighty blast of power closer to what is produced by a black hole. The black hole star, which dates from 660 million years after the Big Bang, was spotted by a U.S.-led team of astronomers using the James Webb Space Telescope, according to a study published Wednesday in the journal Nature. Since history’s most powerful telescope went online in 2022, it has been spotting many extremely bright cosmic objects dubbed “little red dots” in the early universe that have baffled scientists.

“What exactly these objects are has been one of the most debated topics of the JWST era,” lead study author Rohan Naidu of the University of Hawaii said in a statement. The team had been trying to find clues for a different mystery: why JWST keeps finding bright galaxies in the universe’s infancy, when it was thought to have been too early for them to have become so huge. But while looking through the images, they spotted a little red dot. “Pure black hole star light” “When we see something very red in the universe, we often assume that it is surrounded by dust, like soot or ash,” said Robert Simcoe, a study co-author from the Massachusetts Institute of Technology. “The same way that the wildfire smoke from Canada recently made the sky in Boston look bright red, astronomical objects can also appear redder than their intrinsic color when you see them through a veil of dust,” he added.

However, when the team sifted through their data, they found that at certain wavelengths, the object’s light simply disappeared. To their surprise, this suggested that it is not dust making this object appear red — it is hydrogen gas. This explained the object’s color, but not how it could be pumping out so much energy. “You can’t be powering this by nuclear fusion, which is the energy source that sits at the heart of all the stars,” Naidu explained. Using modeling simulations, they determined the most likely scenario was that the object is powered by a central black hole surrounded by a cocoon of gas that makes it resemble a star. The team named the object MoM-BH*-1. The BH and asterisk are for black hole star — and the number one suggests they believe there are more out there. “Every little red dot is consistent with being a black hole star,” Naidu said. “What is special about MoM-BH*-1 is, the black hole star is essentially completely outshining its surrounding host galaxy, such that we’re seeing pure black hole star light.”

Webb reveals dust and water surviving near Milky Way’s central black hole Separately, a team of astronomers announced on Tuesday that the Webb telescope revealed dust and water surviving in the extreme environment of a star located near the Milky Way’s central black hole. Scientists say the new observations provide the most detailed mid-infrared view yet of the star IRS 3, which is located just 0.55 light-years from Sagittarius A*, the Milky Way galaxy’s central supermassive black hole. By analyzing the star’s infrared light with the Webb telescope, the research team identified signs of oxygen-rich dust and, for the first time, detected water in the star’s surrounding envelope. The results show that evolved stars like IRS 3 can still produce dust and other materials important for the creation of future stars – even under the harsh conditions near a supermassive black hole. Webb’s mid-infrared data revealed the clear signature of oxygen-rich silicate dust, as well as, for the first time, water, in IRS 3’s dust envelope. Even under the harsh conditions of its environment, stars can produce dust, which will help create future generations of stars!

“Galactic centers are among the most extreme environments, so understanding whether stars can continue enriching their surroundings there is an important question,” said lead author Florian Peißker of the University of Cologne in Germany. “With Webb, we can directly observe how stars behave under these conditions and see that dust production remains remarkably resilient.”

Hebrews 11:1-3 Now faith is confidence in what we hope for and assurance about what we do not see. This is what the ancients were commended for. By faith we understand that the universe was formed at God’s command, so that what is seen was not made out of what was visible.
