Heaviest pair of supermassive black holes ever measured will someday collide, astronomers report

Black holes are some of the most powerful, destructive and massive objects in the known universe, devouring stars at unimaginable speeds and ripping them apart with such ferocity that they discharge luminous flares visible from millions of lightyears away. When black holes collide into each other, they produce gravitational waves, as scientists learned in 2015 after recording a pair of stellar-mass black holes colliding for the first time....

Three-body solution: These massive blue stars may not be duos, but threesomes instead

Be stars are weird. They are rapidly rotating stars about 4 to 18 times larger than the sun, but a pleasing blue color surrounded by discs of gas, not unlike the rings of Saturn. They spin so fast that they approach “critical velocity” or the point where they would otherwise blast apart due to centrifugal force overpowering the star’s gravity....

Dark matter power: James Webb telescope may have proven the existence of giant dark stars

Since 2007, astronomers have proposed the existence of a weird type of star: one powered by the heat of dark matter. In cosmology, dark matter is a difficult thing to explain because we literally don’t know what it is. We can’t see it, hence the name “dark,” but without it factored into our equations of the universe, things just don’t add up....
