Scientists found the Amaterasu particle, an ultra-energetic cosmic ray, likely came from a nearby star-forming galaxy, not an empty void.
Astronomers observed a short, off-center optical flare from a star being ripped apart by a black hole. This event suggests the black hole is of the elusive intermediate-mass class, located in a dense star cluster far from its galaxy's core.
Scientists found a fast-spinning pulsar near our galaxy's central black hole. If confirmed, its precise pulses could test Einstein's gravity theory under extreme conditions.
