An international team of astronomers has employed the James Webb Space Telescope (JWST) to observe a complex planetary nebula known as NGC 6302. The observations, detailed in a paper published Feb. 25 ...

Hubble Space Telescope images have revealed a second massive collision between planetary bodies orbiting the nearby star ...

The light did not fade the way it was supposed to. After blazing into view about a billion light-years from Earth, the ...

Superluminous supernovas are the brightest stellar explosions in the universe. Astronomers may have found a mechanism that can trigger these events.

WOH G64 has always been an oddball. It sits in the Large Magellanic Cloud, a small galaxy that orbits the Milky Way, and it ranks among the most extreme red supergiants known.

Circumstellar disks as a research area encompasses the observational, theoretical, and computational study of gas and dust structures surrounding young and evolved stars, with emphasis on their ...

NASA's Hubble Space Telescope has provided a complex picture of the star-forming region NGC 1333 that illustrates not only young stellar objects but also circumstellar disks, and variable stars among ...

We report HST NICMOS coronagraphic images of the HD 15115 circumstellar disk at 1.1 mm. We find a similar morphology to that seen in the visible and at H band-an edge-on disk that is asymmetric in ...

The imaging of disks around young stars presents extreme challenges in high dynamic range, angular resolution, and sensitivity. Recent instrumental advances have met these challenges admirably, ...

An artistic rendering of a dust and gas disk encircling the young exoplanet, CT Cha b, 625 light-years from Earth. Spectroscopic data from NASA’s JWST suggest the disk contains the raw materials for ...

ABSTRACT: We have performed self-consistent, three-dimensional, continuum radiative transfer modeling in the disk of HD 100546. Following observations and previous work, the model includes gaps in the ...
