But when researchers at Bell Labs discovered that static tends to come from particular places in the sky, the whole field of radio astronomy opened up.

Description:

A very nice, colour contrasted binary. Not really tight. The primary member (A) is intense golden yellow while the secondary member (B) is blue with a tint of purple. In fact, this is not simply a binary of two stars, but I found out later while doing a research on this object that many of the other stars on this sketch are connected to the primary (as described in this document).
