Total Annihilation for Supermassive Stars

A renegade star exploding in a distant galaxy has forced astronomers to set aside decades of research and focus on a new breed of supernova that can utterly annihilate its parent star — leaving no remnant behind. The signature event,…

An artist’s impression of the binary system Swift J0243.6+6124. A binary system with a neutron star in a 27-day orbit and a more massive, rapidly-rotating donor star. The rapid rotation of the donor star throws off a disk of material around the stellar equator. As the neutron star passes through the disk during its orbit, it picks up some of this outflowing gas, which then spirals in toward the neutron star in an accretion disk.

Neutron Star Jets Shoot Down Theory

Astronomers have detected radio jets belonging to a neutron star with a strong magnetic field — something not predicted by current theory, according to a new study published in Nature. The team, led by researchers at the University of Amsterdam, observed…

Thanks to a rare cosmic alignment, astronomers have captured the most distant normal star ever observed, some 9 billion light years from Earth. (Image: NASA, ESA, and P. Kelly (University of Minnesota))

Hubble Captures Most Distant Star Ever Seen

While astronomers routinely study galaxies much farther away, they’re visible only because they glow with the brightness of billions of stars. And a supernova, often brighter than the galaxy in which it sits, also can be visible across the entire…
