As the article comes from BBC, the following I think is quite interesting:

>> being able to see faint galaxies or supernova explosions that happened “billions of years ago”. >>

Hmm, what do they say about the age of the universe?

I always had my doubts about these numbers…

1 billion is 10^^12, or am I wrong?

No, 10^9. A thousand million.

And Elon Musk is already messing it up!

Starlink satellites are apparently “leaking” radio waves at sensitive frequencies from their on board electronics which are 10,000 times brighter than the distant objects we are trying to observe.

Apparently this is not against the rules as the transmission is “not intentional”. The regulations only cover “intentional transmissions”!!!
