I'm a Craig Ferguson man, truth be told, but I have to give Jimmy Fallon major props for devoting major time to Milky J this week.
C'mon, you remember Milky J: he's the Hubble Gotchu guy. He was on Fallon's show again this week, but this time got some bad news: Hubble will be replaced with the bigger James Webb Space Telescope.
What ensued was simply made of win:
Ha! That was awesome! All those people in the video are actual NASA/Goddard Space Flight Center employees (or contractors; hard to tell). NASA can't buy this kind of publicity, but here it is, handed to them for free. And I love it! It's funny and cool, sarcastic yet has this terrific undertone of sincerity. And Holy Haleakala, the science is accurate*! I loved the part where the team shouts JWST specs at him.
And it doesn't hurt that one of the pictures Milky J holds up at the beginning is of Supernova 1987A, which was the topic of my PhD research. Still, Hubble being replaced isn't a bad thing; JWST will still return amazing images, and also be more sensitive than Hubble to boot. Hubble may gotchu, but JWST will hold you tight.
*OK, fine: Hubble wasn't the first telescope to detect HD 209458b (not "dash b" as Milky J said). It was seen a while before the initial Hubble observations... and no telescope has actually directly pictured; it's too close to its star. But spectra have been obtained, which is pretty cool.
