Wild Theory Suggests Heavy Metals Came From Black Holes

If you were to rank the wildest things in the universe, there are a few obvious contenders: gamma rays, fast radio bursts, and quasars, for example. But no list would be complete without black holes and the black hole’s less-dense cousins, the neutron star. These hyper-compressed things can do some mind-boggling warping to the shape of space itself. So, what happens if one were to eat the other?

Incredible New Observation Shows Supermassive Black Holes Orbiting Each Other

You think our galaxy is special? Ha. Our boring pinwheel of gas and dark matter might be a nice hangout for humans. But 750 or so million light years away, there’s an elliptical galaxy, Galaxy 0402+379, whose two supermassive black holes are orbiting each other from a distance of only 24 or so light years. Their combined mass is around 15 billion times that of our Sun.

Mind-Blowing New Theory Connects Black Holes, Dark Matter, and Gravitational Waves

The past few years have been incredible for physics discoveries. Scientists spotted the Higgs boson, a particle they’d been hunting for almost 50 years, in 2012, and gravitational waves, which were theorized 100 years ago, in 2016. This year, they’re slated to take a picture of a black hole. So, thought some theorists, why not combine all of the craziest physics ideas into one, a physics turducken? What if we, say, try to spot the dark matter radiating off of black holes through their gravitational waves?

NASA’s New X-ray Telescope Will Study the Weirdest Objects in the Universe

Sometimes, the best telescopes on Earth need a little help making their observations more meaningful. NASA announced yesterday that it had decided to fund the Imaging X-ray Polarimetry Explorer (IXPE, pronounced ix-pee) mission, a polarized X-ray telescope, to help the bigger telescopes explore some of space’s strangest phenomena—including the dead remains of exploded stars and galactic lighthouses called pulsars.
