Creating multiple universes to see how they run might be tempting to scientists, but it's obviously not possible. That is, as long as you need physical universes. If you can make do with virtual ones, there are far more options.

Luminous quasar PDS 456 explored with MUSE

Using the Multi Unit Spectroscopic Explorer (MUSE) at the Very Large Telescope (VLT) in Chile, an international team of astronomers has inspected a luminous quasar known as PDS 456. Results of the observational campaign, ...

Observations explore radio jet of a powerful quasar

European astronomers have conducted very long baseline interferometric (VLBI) observations of a radio jet structure in a powerful quasar known as PKS 2215+020. The collected VLBI data provide important insights into the properties ...

A black hole has cleared out its neighborhood

We can't see them directly, but we know they're there. Supermassive black holes (SMBHs) likely dwell at the center of every large galaxy. Their overwhelming gravity draws material toward them, where it collects in an accretion ...
