Gravitational waves reveal 1st-of-its-kind merger between neutron star and mystery object

Astronomers announced on April 5 that they may have detected a collision between a neutron star and a lightweight mystery object — an object larger than the largest known neutron star, but smaller than the smallest known black hole. The finding sheds light on objects that exist in this murky realm, which was long thought to be empty but, in recent times, has revealed otherwise.

Achoo! Baby star ‘sneezes’ tell astronomers a lot about their development

Every new parent knows the cold anxiety that grips them when their baby sneezes for the first time. That’s when a litany of possible issues and ailments probably begin to irrationally race through your mind. Researchers now know baby stars also “sneeze,” but these infinitely more powerful post-natal sneezes launch gas, dust, and magnetic energy. In other words, they’re more useful to the cosmos than stressful.
