An international team of astronomers has used HiCIAO (High Contrast Instrument for the Subaru Next Generation Optics) [Note 1] to observe a disk around the young star SAO 206462. They succeeded in ...

Using the James Webb Space Telescope, scientists spotted thin and thick disks in galaxies as far back as 10 billion years ago—something never seen before. These observations reveal that galaxies first ...

Disk galaxies, like our own Milky Way galaxy, commonly consist of both a thick and thin disk of stars—each with different features, including stellar population and movement. Three major theoretical ...

This image presents a grid of colour-enhanced astronomical observations, each depicting a circumstellar disc—structures of dust and gas surrounding stars. Every square in the grid represents a ...

The figures illustrate the revealed sequential disk formation in this study: thick disk only galaxies dominate the early epochs (bottom panel), while galaxies exhibiting both thin and thick disks ...
