So This is How You Get Magnetars
Magnetars are a type of neutron star with the most powerful magnetic fields in the universe. They're formed by the death of massive stars, like pulsars and other neutron stars. So, what creates such intense magnetic fields? Thanks to a new simulation, astronomers have discovered that a magnetar probably forms when material ejected by the supernova explosion falls back down onto the star's surface, amplifying its dynamo effect.

Can We Develop a More Accurate Habitable Zone Using Sulfur?
The habitable zone is where planets could have liquid water on their surfaces, but not if they're actually habitable. In a new paper, astronomers propose a new way to map the inner edge of habitable zones by searching for sulfur dioxide (SO?) in the atmospheres of exoplanets. If there's SO?, this indicates that the planet doesn't have liquid water on its surface. Telescopes like Webb could scan planets for SO?, creating a more accurate map of habitable zones.

Liquid Mirrors Can Only Point Straight Up. Could Magnets Solve This Problem?
Astronomers have developed several versions of rotating liquid metal telescopes, which use the force of gravity and centripetal force to create a natural telescope lens. They work, but there's a downside: they can only point straight up, in the opposite direction of gravity. A new paper is investigating how electromagnets could work with magnetic fluids (ferrofluids) to shape the liquid into a spherical shape and give it more viewing angles.

What Would Happen if a Tiny Black Hole Passed Through Your Body?
Some astrophysicists theorize that there are primordial black holes, leftover from the formation of the universe. These could have a fraction of the mass of stellar and supermassive black holes and could even be a partial explanation for dark matter. In a new paper, a researcher investigates what would happen to the human body if one of these black holes passed through a person. How much mass, speed and gravity would be dangerous?
