Composite images of the Cas A supernova remnant, a structure resulting from the explosion of a star in the Cassiopeia constellation. The blues represent data from the Chandra Observatory, the ...

NASA’s Imaging X-Ray Polarimetry Explorer which launched Dec. 9, 2021, has delivered its first imaging data since completing its month-long commissioning phase. All instruments are functioning well ...

Using data from NASA’s Imaging X-ray Polarimetry Explorer (IXPE), international researchers have uncovered new information about the Tycho supernova remnant, an exploded star in the constellation ...

An international team of astronomers using NASA’s IXPE (Imaging X-ray Polarimetry Explorer), has challenged our understanding of what happens to matter in the direct vicinity of a black hole. With ...

This NASA illustration shows the structure of a black hole jet as inferred by recent observations of the blazar Markarian 421 by the Imaging X-ray Polarimetry Explorer (IXPE). The jet is powered by an ...

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 ...

A NASA X-ray instrument has provided a new view of one of astronomy’s most beautiful objects, the Crab Nebula. The Imaging X-ray Polarimetry Explorer or IXPE observatory was launched in December 2021 ...

It is no secret that at the center of our galaxy, the Milky Way, lies a supermassive black hole better known as Sagittarius A ...

Astronomers have revealed more dramatic details of one of our most ghostly discoveries, the pulsar wind nebula MSH 15-52, also known as the ‘cosmic hand’ or 'hand of God'. By combining the powers of ...

A 'beautiful effect' predicted by quantum electrodynamics (QED) can explain the puzzling first observations of polarized X-rays emitted by a magnetar -- a neutron star featuring a powerful magnetic ...
