A high-altitude balloon telescope has revealed new patterns in X-rays emitted near the black hole Cygnus X-1. These signals ...

Scientists flew the XL-Calibur telescope on a high-altitude balloon to measure polarized X-rays from Cygnus X-1. These ...

How confusing inevitability with reality built decades of paradox. What if general relativity never actually tells us that ...

Astronomers have now obtained a new view of the supermassive black hole at the center of galaxy M87. Images released today by the Event Horizon Telescope (EHT) collaboration reveal how the black hole, ...

An artist’s impression of the Cygnus X-1 system, with the black hole appearing in the center and its companion star on the left. New measurements from Cygnus X-1, reported Nov. 3 in the journal ...

The trip took place in July 2024 and took 6 days. Over that time, the flying observatory looked at two main sources: the Crab ...

Long before rockets and satellites reached space, the Crab Nebula stood out as a steady beacon of high-energy light. At its ...

An international collaboration of physicists has made measurements to better understand how matter falls into black holes and ...

The XL-Calibur balloon telescope captured precise X-ray polarization data from the Cygnus X-1 black hole, offering new ...

A black hole’s bizarre "heartbeat" is forcing astronomers to reconsider how these cosmic heavyweights behave. Observations of IGR J17091-3624 — a black hole in a binary system roughly 28,000 ...

The team behind new research on the topic suggests that measuring whether gravitational waves from black hole mergers are right- or left-handed can tell us if the Cosmological Principle — an absolute ...
