A time lapse video showcasing the evolution of supernova SN1987A over 30 years is highlighted, with a link to a New York Times article provided for viewers. The video captures the supernova's changes since its explosion, sparking nostalgia among viewers about the event's significance. Participants reminisce about observing SN1987A, the first naked-eye supernova in 300 years, and the excitement of capturing it alongside Comet Wilson in a photograph. There is a mention of the challenges of pre-digital photography, with one user expressing a desire to locate and digitize original negatives. The discussion emphasizes the lasting impact of SN1987A on both astronomy and personal memories.
It has a time lapse video of SN1987A since its explosion 30 years ago.
ohhhh man, 30 yrs ago ! where has my life gone ?? haha
it was a thrill to observe the first naked eye SN in 300 years
and an even bigger thrill to capture it and Comet Wilson in the same photo frame ( long before digital cameras)
will have to dig up the original negatives one day and scan themDave

Is a homemade radio telescope realistic?
There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs.
Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
