This image features 3C 297 that is lonelier than expected after it likely pulled in and absorbed its former companion galaxies. In this new composite image, Chandra data is colored purple, VLA data is red and Gemini data is green. Visible light and infrared data from Hubble (blue and orange respectively) have also been included.

ALMA Spots Hidden Jet from Oddball Star MWC 349A

Jan 9, 2023 by News Staff

The jet observed by the Atacama Large Millimeter/submillimeter Array (ALMA) is ejecting material away from MWC 349A at a blistering 500 km per second (311...

This Webb image shows the Cosmic Cliffs, a region at the edge of a gigantic, gaseous cavity within the stellar nursery NGC 3324. The image is divided horizontally by an undulating line between a orange-burgundy cloudscape forming a nebula along the bottom portion and a comparatively blue upper portion.

Astronomers Detect Very Luminous Jet from Star-Eating Supermassive Black Hole

Dec 1, 2022 by News Staff

A supermassive black hole devours a star that has come too close. In extremely rare instances — only about 1% of the time — these so-called...

This illustration shows the IXPE spacecraft (right) observing the blazar Markarian 501 (left). A blazar is a black hole surrounded by a disk of gas and dust with a bright jet of high-energy particles pointed toward Earth. The inset illustration shows high-energy particles in the jet (blue). When the particles hit the shock wave, depicted as a white bar, the particles become energized and emit X-rays as they accelerate. Moving away from the shock, they emit lower-energy light: first visible, then infrared, and radio waves. Farther from the shock, the magnetic field lines are more chaotic, causing more turbulence in the particle stream. Image credit: NASA / Pablo Garcia.

IXPE Spacecraft Examines Particle Acceleration in Blazar Jets
