A Decade of NuSTAR: What Its X-Ray Vision Has Taught Us

August 3rd, 2022

NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), led by Caltech and managed by JPL, turned 10 years old in June. This space telescope detects high-energy X-ray light and studies some of the most energetic objects and processes in the universe.

Black holes can tell us the expansion rate of the Universe

November 10th, 2021

Astronomers have discovered a new way to determine the current expansion rate of the Universe, known as the Hubble constant, using X-ray observations of supermassive black holes at the centre of distant galaxies that are gobbling up huge amounts of gas, known as active galactic nuclei. This could settle an on-going dispute between the two existing methods, which disagree on the age of the Universe by more than a billion years.

A Tale of Two Coronae: Solving the Mystery of the “Soft Excess”

March 26th, 2021

Astronomers are investigating the mystery of the “soft excess” of low-energy X-ray emission often seen from accreting supermassive black holes. This enigmatic component can carry a large fraction of the X-ray flux, but is poorly understood. Multiple theories have been suggested. Simultaneous observations with NuSTAR (at high energy X-rays) and XMM-Newton (at low-energy X-rays) provide a powerful combination to investigate its origin.

In Colliding Galaxies, a Pipsqueak Shines Bright

February 20th, 2019

In the nearby Whirlpool galaxy and its companion galaxy, M51b, two supermassive black holes heat up and devour surrounding material. These two monsters should be the most luminous X-ray sources in sight, but a new study using observations from NASA's NuSTAR mission shows that a much smaller object is competing with the two behemoths.

How Strong are Black Holes Really?

December 7th, 2017

Black holes are famous for their muscle: an intense gravitational pull known to gobble up entire stars and launch streams of matter into space at almost the speed of light. It turns out the reality may not live up to the hype. University of Florida scientists have discovered these tears in the fabric of the universe have significantly weaker magnetic fields than previously thought.

NuSTAR Probes Black Hole Jet Mystery

October 30th, 2017

Black holes are famous for being ravenous eaters, but they do not eat everything that falls toward them. A small portion of material gets shot back out in powerful jets of hot gas, called plasma, that can wreak havoc on their surroundings. Along the way, this plasma somehow gets energized enough to strongly radiate light, forming two bright columns along the black hole's axis of rotation. Scientists have long debated where and how this happens in the jet.
