  1. Musk's #satellites 'blocking' view of the #universe

    by Georgina Rannard

    "#RadioWaves from #ElonMusk’s growing network of satellites are blocking scientists’ ability to peer into the universe, according to researchers in the Netherlands.

    "The new generation of Starlink satellites, which provide fast internet around the world, are interfering more with #RadioTelescopes than earlier versions, they say.

    "The thousands of orbiting satellites are 'blinding' radio telescopes and may be hindering astronomical research, according to Netherlands Institute for Radio Astronomy (#ASTRON).

    "#SpaceX, which owns Starlink, has not replied to a request from BBC News for comment.

    "The satellites provide broadband internet around the world, often to remote places, including challenging environments like Ukraine and Yemen.

    "They are also used to connect remote areas of the UK to fast internet. In 2022 tests showed that Starlink could deliver internet speeds four times faster than the average, according to the Department for Digital, Culture, Media and Sport.

    "But astronomers say this comes at a cost.

    "'Every time more of these are launched with these kinds of emission levels, we see less and less of the sky,' Professor Jessica Dempsey, director of ASTRON, told BBC News."

  5. A whole bunch of bonus Fediverse points if you can guess the telescope, the acronyms, and how they’re connected. 😁😁

    Also, I really really love painting radio telescopes, and not just because I get to play with masking fluid!

  8. After having spent many years with my #SKAO colleagues in the definition of the SKA telescopes’ definition it is great to see action in the construction of the first Array Assembly, AA0.5 of the SKA-LOW telescope! cosmosmagazine.com/space/squar #radiotelescopes #radioastronomy #SKA #SKA-LOW

  9. I did an #Introduction when I joined mastodon.green, but I guess another one is needed for #Astrodon. I currently work in #SystemsEngineering for #RadioTelescopes (in particular, the #ALMA radio interferometer). I’ve also worked in software development and management for the #SKAO observatory, and for the archive department at #ESO. Glad to see you around!
