The fifth episode of the rebooted Cosmos will feature an old friend from the Final Frontier.

If you're still not watching the Neil deGrasse Tyson-hosted reboot of Carl Sagan's classic science miniseries Cosmos, you're missing out on a rare broadcast-television-led trip into the heart of science that's packed with astounding visuals, endlessly repeatable facts and plenty of other nerd-worthy goodies. it's clear that Cosmos has set out to, among other things, inspire us, and now we can be inspired even more with the arrival of a legendary Star Trek star on the program.

If you haven't been watching, Cosmos is a combination of live-action/CGI shots starring Tyson and animated segments chronicling the great scientific discoveries of the past. This Sunday's episode, "A Sky Full of Ghosts," will feature even more animated storytelling, and this time those segments will star Capt. Jean-Luc Picard himself, Sir Patrick Stewart.

Stewart will voice 19th-century astronomer William Herschel, who will explain to his son how gravity and time affect how we perceive light. Check out the clip below, in which Stewart's Herschel articulates how we can see the light from a star that has already gone out. 

"A Sky Full of Ghosts" will air Sunday at 9/8 C on Fox, and the following Monday on the National Geographic Channel. If you still haven't gotten onboard the (very, very fun) Cosmos train, this might be a perfect time to change that.
