NEW: Astronomers Map Mysterious “Dark” Gas in the Milky Way

For the first time, astronomers using the Green Bank Telescope have created a large-scale map of a mysterious form of matter known as CO-dark molecular gas.

How many stars form in compact clusters in the local Milky Way? Two main models coexist for the environment in which stars form. The clustered model stipulates that the bulk of star formation occurs within dense embedded clusters, but only a minority of them survi...

Most stars form in clusters! 🔭🧪☄️ #galactic

In a new paper led by @alexis-space.bsky.social, we show that >80% of stars in the local Milky Way formed in clusters.

This is *much* higher than other recent estimates (~15%), and supports more traditional 'clustered' models of star formation!

Star formation primarily takes place within compact clusters in the local Milky Way! 🌌 #galactic #stellarastro

We've shown this combining the results from two recent, Gaia-based catalogues: the open clusters census from @emily.space and my census of OB stars within 1 kpc!

Slide of all the radio recombination lines that are available in SKA bands.

Graphic of the gravitational lens in which the radio recombination lines were detected.

Slide of the derived properties of the galaxy: density of the gas, star formation rate surface density, SFR = 50 M_Sun/yr

Slide with plots showing the galaxy appears to be a main sequence galaxy, that sits on Kennicutt-Schmidt relation.

Kimberly Emig talking about radio recombination lines with the SKA and how to observe them in galaxies through cosmic time! Recent detection of PKS 1830-211 at z=0.89 with MeerKAT and combined with HI & OH can say a lot of gas properties and what kind of a star forming galaxy it is. #skao2025 🔭📡

Access to radio frequencies enables key science from weather prediction to astronomy. A new @nationalacademies.org report discusses ways to protect scientific uses of the radio spectrum in advance of the World Radiocommunication Conference in 2027. www.nationalacademies.org/our-work/vie...

Don't miss your chance!

We're creating a giant 3200-megapixel group photo in the shape of our huge LSST Camera's focal plane, and it won't be complete without you! 🔭 🧪

Radio Recombination lines have now been detected from proplyds! the line emission is mainly coming from an (externally) ionized cloud surface layer that is ~0.01 AU wide, the thickness of the ionization front 😲 great work, Ryan!! public.nrao.edu/news/alma-de...

The MeerKAT Absorption Line Survey (MALS) data release 3: Cold atomic gas associated with the Milky Way We present results of a blind search for Galactic HI 21-cm absorption lines toward 19130 radio sources, using 390 pointings of MALS, each pointing centered on a source brighter than 200 mJy. We detect...

The third MALS data release, consisting of Galactic HI 21-cm spectra of about 20,000 radio sources is now public! It represents the largest Galactic HI absorption line catalog to date.
