Astronomers Capture First Image of Orbiting Black Hole Pair

Astronomers have achieved a milestone by capturing the first visual evidence of two black holes orbiting each other, located 5 billion light-years from Earth. The observation, made using a network of radio telescopes including the RadioAstron satellite, reveals a smaller black hole with a jet of nea... [More info]

This is my second migration on Mastodon, so I think an Introduction might be in order. I'm moving in to this account (that had lived independently, to test some of Mathstodon features) after astrodon.social is being sunset. Hope that Astrodon as a concept still lives!

I currently work in Systems Engineering for radio telescopes (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. Of course, I'm also very interested in math (specially that having to do with system theory), so I'll try to get a bit stronger there.

Glad to see you all around!

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

"#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."
