A study analyzed 178 debris-disc systems and found that many of these disks likely require the presence of Neptune- to Saturn-mass planets at distances of 10 to 100 astronomical units (au ...

Using the Keck Planet Imager and Characterizer (KPIC), astronomers have performed high-resolution spectroscopic observations ...

In 1984, the first debris disk orbiting another star was observed around Vega. Think of a debris disk as the leftovers from solar system formation, analogous to the asteroid or Kuiper belts.

Scientists have previously found old stars surrounded by disks of debris, which probably comprise the pulverized remains of small planets or asteroids. What they hadn’t seen was such a disk ...

This image of the dusty debris disk surrounding the young star Fomalhaut is from Webb’s Mid-Infrared Instrument (MIRI). It reveals three nested belts extending out to 14 billion miles (23 ...

The architecture of the Fomalhaut debris disk system. We highlight the various features identified ... [+] in the JWST/MIRI observations of the Fomalhaut system in this 25.5 μm image.

As Isabel Rebollido, lead author on the new research, explains, “Beta Pictoris is the debris disk that has it all: It has a really bright, close star that we can study very well, and a complex ...

The James Webb Space Telescope (JWST) has captured a remarkably smooth, "pancake-like" disk of debris surrounding the star Vega, offering new insights into its cosmic environment. The images ...
