X-ray study sheds more light into the nature of a gamma-ray pulsar

3 arcmin × 3 arcmin Chandra X-ray image of the pulsar vicinity in 0.5–10 keV range smoothed with a 25 pixel Gaussian kernel. The ‘+’ symbol shows the pulsar position. The ‘jet’ and ‘counter-jet’ are marked. The 30 arcsec × 30 arcsec image part, enclosed by the cyan dashed box and smoothed with a 3 pixel Gaussian kernel, is enlarged in the inset. The possible PWN torus and the base part of the ‘jet’ are marked.

Using archival data from ESA's XMM-Newton spacecraft and NASA's Chandra X-ray observatory, astronomers have investigated one of gamma-ray radio-quiet pulsars known as PSR J1826−1256. The study, based on X-ray observations, sheds more light into the nature of this peculiar object and its pulsar wind nebula (PWN). Results of the research

Where is the universe hiding its missing mass?

Chandra X-ray Center

Astronomers have spent decades looking for something that sounds like it would be hard to miss: about a third of the "normal" matter in the Universe. New results from NASA's Chandra X-ray Observatory may have helped them locate this elusive expanse of missing matter.From independent, well-established observations, scientists have confidently

Making head or tail of a galactic landscape

X-ray astronomy

Astronomers have used data from NASA's Chandra X-ray Observatory to capture a dramatic image of an enormous tail of hot gas stretching for more than a million light years behind a group of galaxies that is falling into the depths of an even-larger cluster of galaxies. Discoveries like this help
