Instead of a tempest in a teapot, imagine the cosmos in a canister. Scientists have performed experiments using nested, ...

Astronomers from the University of Turku in Finland and elsewhere have performed a broadband spectral and timing study of an ...

Astronomers uncover how massive stars form by tracking interstellar ammonia. Using the U.S. National Science Foundation ...

A microquasar belonging to our Milky Way galaxy has set records by generating cosmic rays with energy levels never before ...

Using the XMM-Newton telescope, astronomers have witnessed high-speed "burps" erupting from a distant overfeeding ...

One of the most powerful objects in the universe is a radio quasar—a spinning black hole spraying out highly energetic particles. Come too close to one, and you'd get sucked in by its gravitational ...

The accretion disk around a black hole can form a jet of hot, energetic particles surrounded by magnetic field lines. NASA, ESA, and A. Feild (STScI), CC BY ...

Using the James Webb Space Telescope, astronomers have witnessed the dramatic dance between a supermassive black hole-powered quasar and merging galaxies less than a billion years after the Big Bang.

Despite the oddities, this object looks a lot like quasars in more recent times: "Our observations demonstrate that the complex structures of the dusty torus and the [accretion disk] can establish ...

An artist’s impression of a quasar wind (in light blue) being launched off of the accretion disk (red-orange) around a supermassive black hole. Clouds of gas in a distant galaxy are being pushed ...
