Huge Burst of Mysterious Cosmic Radio Signals Traced Back To Exact Location in Galaxy Billions of Light Years Away

fast radio burst

A huge one-off burst of mysterious cosmic radio waves has been precisely located to a galaxy 3.6 billion light years away. The powerful shiver of waves came from a Milky Way-sized galaxy that scientists were able to pinpoint for the first time using three of the world’s largest optical telescopes.“This is the big breakthrough that

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

Advanced civilizations could be communicating with neutrino beams

In 1960, famed theoretical physicist Freeman Dyson made a radical proposal. In a paper titled "Search for Artificial Stellar Sources of Infrared Radiation," he suggested that advanced extra-terrestrial intelligences (ETIs) could be found by looking for signs of artificial structures so large that they encompass entire star systems (also known

Hubble peers at cosmic blue bauble

Messier 3: Containing an incredible half-million stars, this 8-billion-year-old cosmic bauble is one of the largest and brightest globular clusters ever discovered.

Globular clusters are inherently beautiful objects, but the subject of this NASA/ESA Hubble Space Telescope image, Messier 3, is commonly acknowledged to be one of the most beautiful of them all.Containing an incredible half-million stars, this 8-billion-year-old cosmic bauble is one of the largest and brightest globular clusters ever discovered.

The First-Ever Close-Up of a Black Hole

The first-ever image of a black hole was released Wednesday by a consortium of researchers, showing the "black hole at the center of galaxy M87, outlined by emission from hot gas swirling around it under the influence of strong gravity near its event horizon."

You're looking at the brand-new, first-ever close-up picture of a black hole. This image of the black hole M87 at the center of the Virgo A galaxy is the result of an international, 2-year-long effort to zoom in on the singularity. It reveals. for the first time, the contours of
