The white dwarf ZTF J1944+4557 plays hide-and-seek: its light dims by 30% every 4 hours 58 minutes. The dust particles here are no smaller than 0.2 microns and they dim all colors of the spectrum equally. But the strangest twist: the pattern of eclipses changes faster than the orbit, and sometimes a

Normally, black holes rip stars apart in the centers of galaxies. A new discovery shows that some black holes lurk in the outskirts. Astronomers spotted a flare tens of thousands of light-years from the center of a large galaxy. A computer algorithm trained on similar events helped identify it. Soon
