NSF VLA and ALMA observations detect enormous cold molecular gas reserves in a distant galaxy seen 13 billion years ago, a study involving Hiroshima University reports.

Astronomers have uncovered a previously unknown, extreme kind of star factory by taking the temperature of a distant galaxy using the ALMA telescope. The galaxy is glowing intensely in superheated cosmic dust while forming stars 180 times faster than our own Milky Way. The discovery indicates how galaxies could have grown quickly when the universe was very young, solving a long-standing puzzle for astronomers.

A group of researchers have observed images from the James Webb Space Telescope. The images were like a time machine, allowing the researchers to understand how these galaxies built their disks over history and compare this to how our own Milky Way formed.

An international team of astronomers has revealed a new map of the Milky Way galaxy’s outer disc showing remains of tidal arms excited from interactions with satellite galaxies in the distant past.

Astronomers at the National Astronomical Observatory of Japan have analyzed the paths of two objects heading out of the Solar System and determined that they likely originated from outside of the Solar System.
