V404 Cygni Rings (Credit: X-ray: NASA/CXC/U.Wisc-Madison/S. Heinz et al.; Optical/IR: Pan-STARRS) A spectacular set of rings around a black hole has been captured using NASA’s Chandra X-ray Observatory and Neil Gehrels Swift Observatory. The X-ray images of the giant rings have revealed new information about dust located in our Galaxy, using a similar […]

The orphan cloud is the blue umbrella-shaped part of this image, which is color-coded to show the X-ray part of the cloud in blue, the warm gas in red, and the visible region in white. Credit: Ge et al (2021) A scientifically mysterious, isolated cloud bigger than the Milky Way has been […]

The north-south velocity associated with the retrograde propagating mode of oscillation. Left: observations using the SDO/HMI instrument. Right: numerical model.

These motions were measured by analyzing […]

Brown dwarfs, such as the one seen in this illustration, are actually orange or red, and they glow brightest in the infrared part of the spectrum. PHOTOGRAPH: NASA/JPL-CALTECH/2MASS The brown dwarf isn’t a star and it’s not a planet. But it’s illuminating the murky borderlands that separate the two. DAN CASELDEN […]

ANIMATION Emirati national Aisha Al Yazeedi, a research scientist at the NYU Abu Dhabi (NYUAD) Center for Astro, Particle, and Planetary Physics, has published her first research paper, featuring some key findings on the evolution of galaxies. Galaxies eventually undergo a phase in which they lose most of their gas, which […]

If asked to pick what color asteroids in the asteroid belt would be, red is likely not one that would come to mind for most people.  But that is exactly the color of two new asteroids found by Hasegawa Sunao of JAXAand an international team of researchers.  The catch is the objects don’t […]

An illustration of a black hole. (Image credit: Mark Garlick/Science Photo Library) The “luminous echoes” come from the rear part of the black hole’s corona Astronomers have detected light coming from behind a black hole for the first time, proving Albert Einstein right, yet again. Researchers were studying the X-rays flaring from a supermassive black hole […]

When the core of massive star collapses, it can form a black hole. Some of the surrounding matter escapes in the form of powerful jets that rush outward at almost the speed of light in opposite directions, as illustrated here. Normally jets from collapsing stars produce gamma rays for many […]
