Astronomers have discovered the first radio signals from a unique category of dying stars, called Type Ibn supernovae, and ...

Radio telescopes let you study the universe by collecting faint radio waves from distant objects. To see extremely small targets, such as the regions around supermassive black holes, those telescopes ...

Very-long baseline interferometry (VLBI) is a technique in radio astronomy whereby multiple radio telescopes cooperate to ...

This is why we now build radio telescopes as arrays of smaller dishes and use interferometry to create a virtual dish the size of the array. Both M87* and Sag A* have an apparent size of about 40 ...
