Astronomers have reported one of the longest stellar dimming events ever recorded, with a Sun-like star fading by 97 percent for nearly 200 days. Astronomers believe one of the longest stellar dimming ...

Now researchers think they've solved the mystery of one of the longest star-dimming events ever recorded. The star, called ASASSN-24fw, may have disappeared behind a giant planet with an enormous ...

Analysis of samples returned from the carbonaceous asteroid Bennu suggests that amino acids could form in the cold fringes of ...

One of the longest stellar dimming events ever observed was likely caused by the gigantic saucer-like rings of either an unseen brown dwarf or "super-Jupiter" blocking its host star's light, ...

An international team of astronauts have conducted a detailed study of planets being born around young stars. The observations have resulted in the sharpest images ever of 24 circumstellar disks.

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 Hubble Space Telescope has detected the most expansive protoplanetary disk documented to date, extending across 400 billion miles, approximately 40 times the size of the solar system. The findings ...

DD News brings a science report on a new finding by Indian astronomers using data from the James Webb Space Telescope. Researchers have identified complex hydrocarbon molecules in the disk of a young ...

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 ...
