A Rapidly-Growing Black Hole in a Nearby Galaxy Could Provide a Window Into the Early Universe.

The black hole at the centre of a nearby galaxy is growing exceptionally fast, and is producing a burst of radio emission that has never been observed before. With characteristics that are expected in the early Universe, this unique galaxy provides important insights into the processes that governed the growth of the first black holes. from Universe Today https://ift.tt/9rMu5BX via IFTTT

Only Binary Stars Can Create Interacting Supernovae

When a massive star reaches the end of its life, it explodes as a supernova that can light up the sky for months. But some supernovae stay luminous for much longer, and astrophysicists have wondered what causes their extended brightness. New research points to binary stars, where one star expels material right before the explosion that creates a cocoon of circumstellar medium. from Universe Today https://ift.tt/ek5ctFb via IFTTT

7,000 Galaxy Clusters, Hiding in Plain Sight

A five year survey by the South Pole Telescope has produced a catalogue of more than seven thousand galaxy clusters, some dating back nearly eight billion years, giving astronomers their most detailed map yet of the universe's largest structures. Hidden inside the data is something even the researchers did not expect, a discovery that is quietly reshaping how we think star formation unfolded across the history of the universe. from Universe Today https://ift.tt/FZnJScW via IFTTT

Detecting Atomic Weapons in Space

The Outer Space Treaty from 1967 prohibits weapons in space. But a satellite launched by Russia has generated suspicion. Despite claims that it's a normal satellite, some things about it suggest otherwise. New research proposes a way to detect atomic weapons in space, helping enforce the treaty. from Universe Today https://ift.tt/KRUw0oB via IFTTT
