Astronomers track bubbles on a star’s surface in the most detailed video yet
For the first time, astronomers have captured images of a star other than the Sun in enough detail to track the motion of bubbling gas on its surface. The images of the star, R Doradus, were obtained with the Atacama Large Millimeter/submillimeter Array (ALMA), in July and August 2023. They show giant, hot bubbles of [...]

SKAO: exciting milestone achieved withrelease of the ‘first fringes’ from the Observatory’s SKA-Low telescope
First fringes refers to the successful correlation of data from separate antennas stations – in this case two stations – signifying that SKA-Low has begun to work as an interferometer. Both of the SKA Observatory’s telescopes – SKA-Low in Western Australia and its counterpart SKA-Mid in South Africa’s Northern Cape – are radio interferometers. They [...]
INAF: Open Call
The call for proposal for observing with the INAF telescopes is open. See here. INAF participates with the Sardinia Telescope (SRT) in the Transnational Access program of the Opticon Radionet Pilot program (ORP), which is funded by the EC Horizon 2020 Research and Innovation Programme under grant agreement No. 101004719. For observations with the STR [...]
Second-Generation Starlink Satellites Leak 30 Times More Radio Interference, Threatening Astronomical Observations
Observations with the LOFAR (Low Frequency Array) radio telescope last year showed that first generation Starlink satellites emit unintended radio waves that can hinder astronomical observations. New observations with the LOFAR radio telescope, the biggest radio telescope on Earth observing at low frequencies, have shown that the second generation ’V2-mini’ Starlink satellites emit up to [...]
New AtLAST Newsletter issued
AtLAST is a concept for a next generation 50-meter class single-dish astronomical observatory operating at sub-millimeter and millimeter wavelengths, run as a facility telescope by an international partnership and powered by renewable energy. AtLAST has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 951815 Furthermore, AtLAST announced that the [...]
The MeerKAT Absorption Line Survey: A million radio sources probe the motion of the solar system and provide a fundamental test of cosmology
Using data from the MeerKAT radio telescope, an international team of astronomers from the MeerKAT Absorption Line Survey (MALS) collaboration have compiled the largest catalog of radio sources from any MeerKAT survey to date. With this catalog, they were able to make a measurement of the cosmic radio dipole, a cosmological effect that arises from [...]
