Astronomers discover a rare ’black widow’ binary, with the shortest orbit yet
The flashing of a nearby star drew the attention of a team of astronomers, who discovered that it is part of a rare and mysterious system. As they report in a paper published May 4 in Nature, the stellar oddity appears to be a “black widow binary” — a type of system consisting of a rapidly spinning neutron star, or pulsar, that is circling and slowly consuming a smaller companion star, as its arachnid namesake does to its mate.

All the data in the sky, alerted via UW eyes
The Zwicky Transient Facility, based at the Palomar Observatory, has identified over a thousand new objects and phenomena in the night sky, including more than 1,100 new supernovae and 50 near-Earth asteroids. University of Washington scientists are part of the ZTF team and led the development of the collaboration’s alert system, which informs science teams of possible new objects or changes to known objects in the sky.

With launch of new night sky survey, UW researchers ready for era of ‘big data’ astronomy
The first astronomers had a limited toolkit: their eyes. They could only observe those stars, planets and celestial events bright enough to pick up unassisted. But today’s astronomers use increasingly sensitive and sophisticated instruments to view and track a bevy of cosmic wonders, including objects and events that were too dim or distant for their…
