Black holes

In January 2014, Chandra X-Ray Observatory claimed to have made discovery of a new supermassive black hole candidate disrupting star in the Abell 1795.[4][5]

gollark: Let's Encrypt is *also* automatic, so no fiddling around with renewals needed.
gollark: Yes, it does get around stupid stuff configured to block non-80/443 ports.
gollark: Modern reverse proxies/webservers (caddy/træfik are the ones I know of) do nice things like configuring SSL/TLS with Let's Encrypt automatically.
gollark: It will? Madness.
gollark: If you try and use it to proxy, I don't know, telnet, it'll not work.
