International teams of astronomers monitoring a supermassive black hole in the heart of a distant galaxy have detected features never seen before using data from NASA missions and other facilities. The features include the launch of a plasma jet moving at nearly one-third the speed of light and unusual, rapid X-ray fluctuations likely arising from near the very edge of the black hole.

Quasars, among the universe's oldest and most luminous entities, are formed by active galactic nuclei (AGN) powered by supermassive black holes drawing in surrounding matter. These celestial objects emit electromagnetic radiation detectable across a broad spectrum, including radio, infrared, visible, ultraviolet, X-ray, and gamma-ray wavelengths.

The European Space Agency's XMM-Newton observatory has revealed unexpected X-ray oscillations emanating from the edge of a supermassive black hole in a nearby galaxy. These findings challenge existing theories of black hole accretion and offer intriguing clues about potential gravitational wave sources for ESA's upcoming LISA mission.

The name "blue lurker" might sound like a villainous character from a superhero movie. But it is a rare class of star that NASA's Hubble Space Telescope explored by looking deeply into the open star cluster M67, roughly 2,800 light-years away.

Solar storms, with their awe-inspiring displays like the aurora borealis, have captivated humans for centuries. However, these phenomena, caused by solar flares - intense bursts of energy from the Sun - pose significant challenges. Severe solar storms can disrupt telecommunications, satellites, and power grids, creating widespread consequences for global society.

A whitish-grey patch that occasionally appears in the night sky alongside the aurora borealis has been explained for the first time, thanks to researchers at the University of Calgary. The phenomenon, known as "structured continuum emission," has long intrigued scientists but had never been fully understood until now.
The findings, published on Dec. 30 in the journal Nature Communications,
