We are given a strange message from nc:
$ nc jupiter.challenges.picoctf.org 9422
.--. .. -.-. --- -.-. - ..-. { -- ----- .-. ... ...-- -.-. ----- -.. ...-- .---- ... ..-. ..- -. ..--- -.... ---.. ...-- ---.. ..--- ....- -.... .---- ----- }
Ncat: Broken pipe.
We see that the message has only . and - (and also braces, indicating that the message might be the flag). In fact, the message is Morse code. We can use CyberChef to decode it:

So the flag is: picoCTF{M0RS3C0D31SFUN2683824610}.
