ALMA

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found rings, gaps and cavities inside four of 11 very small planet-forming disks, a class of disk that had looked smooth…

Almost everything anyone knows about when the Solar System began rests on a few pale specks inside meteorites. They are calcium-aluminum-rich inclusions, grains condensed from hot gas close to the…

A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) reports the first detection in space of fully deuterated methanol, found in the gas around a star that is still…

Astronomers have used the James Webb Space Telescope to take mid-infrared spectra of large soot-like carbon molecules in five ordinary star-forming galaxies at a redshift of about 1, the era known as…

The scenario is decades old and mostly drawn from simulations. A young gas giant plows through the disk of gas and dust it was born in, and the gas closest to it stops moving the way the rest of the…

Astronomers pointed the James Webb Space Telescope at five young stars to photograph giant planets inferred from the motion of gas around them, and found no sign of any. The planets have never been…

Almost every massive star in the galaxy has a companion, and almost everything known about those pairs comes from looking at them long after they finished forming. By then the orbit has had millions…
