Wandering black holes

Every massive galaxy is believed to host a supermassive black hole (SMBH) at its center. Its mass is correlated with the mass of the inner regions of its host (and also with some other properties), probably because the SMBH ...

Research examines emission from the blazar TXS 0506+056

Using the Very Energetic Radiation Imaging Telescope Array System (VERITAS), an international team of astronomers has conducted long-term observations of a gamma-ray blazar known as TXS 0506+056. Results of the observational ...

Teaching Einsteinian physics in schools

Why are middle school students losing interest in physics? Why is Australia falling behind in science, technology, engineering and mathematics (STEM)?

Black hole size revealed by its eating pattern

The feeding patterns of black holes offer insight into their size, researchers report. A new study revealed that the flickering in the brightness observed in actively feeding supermassive black holes is related to their mass.

V404 Cygni: Huge rings around a black hole

This image features a spectacular set of rings around a black hole, captured using NASA's Chandra X-ray Observatory and Neil Gehrels Swift Observatory. The X-ray images of the giant rings reveal information about dust located ...

Dancing ghosts point to new discoveries in the cosmos

Researchers from Western Sydney University and CSIRO, Australia's national science agency, have discovered strange clouds of electrons surrounding galaxies deep in the cosmos. The clouds, which are about a billion light years ...
