Oh this ones for older kids LOL
studying for astronomy mid terms; bless this series
Does welding safety glasses safe to use? I've seen the sun eclipse using welding safety glasses.
Your videos aways help me ace my science exams thanks!
I'm just trying to study for an astronomy test and suddenly Rhett and Link.
I thought it is a lunar occlusion not eclipse
Was that Rhett and link
I really am glad that scientists will try and name things linking back to ordinary objects, events, ect. So much easier to remember than say trying to remember Latin names of organism but not knowing Latin.
Awesome video! It's really helping me in my astronomy class!
what happens to the weight of the moon in solar eclipses when the moon is caught between the competing gravities of the earth and sun on it – both pulling it but in opposite direction?
:O IT'S RHETT AND LINK
Yay! I think I'm at the right place to watch a total solar eclipse at the right time. Coz I live in Sri Lanka!!
1:04 – Shouldn't the Earth be bigger? Like 2-3 times bigger?
two days ago there was a super bloodmoon.. :D.. im glad ive seen it!
hey blood moon lunar eclipse tonight woo-hoo!!
Lunar eclipse is happening right now as i type this in London !
Lunar eclipse in about an hour from now :D
Hm. Well at least I can say that I saw a total solar eclipse when I was young.
