Escape Velocity!!!!!!!

You’re lying - those are way cooler than dumb fireworks!

I really don’t like fireworks. They’re environmentally damaging, loud, and they hide the stars!

So yeah, July 4th wasn’t too happy for me.

A camera on the Vosges mountains in France captured these surprising “fireworks” above the horizon. Generated over intense thunderstorms, these brief and mysterious flashes have come to be known as red sprites. The transient luminous events are caused by electrical breakdown at altitudes of 50 to 100 kilometers. That puts them in the mesophere, the coldest layer of planet Earth's atmosphere. The glow beneath the sprites is from lightening under the clouds.

On the right, the video frames have captured another summertime apparition from the mesophere. The silvery veins of light are polar mesospheric clouds. Also known as noctilucent or night shining clouds, the icy clouds still reflect the sunlight when the Sun is below the horizon.

Okay I love the Big Bang Theory (as in the actual scientific theory about the start of our universe) but also the TV show.

(Sheldon was my favorite)

Anyway I didn’t know there was a full version of the theme song and I really like it :)

I'm watching the launch now, half an hour to go!

This is the first NASA astronaut launch since 2011. I wanted to go to Cape Canaveral to watch but instead I'm watching from afar :)

(Edit: they’ve put off the launch till Saturday due to weather)

It’s easy to forget that thousands of comets, asteroids, and meteors are near us everyday. They seem like such a rarity.

Cosmonaut Ivan Vagner obtained this image of the comet NEOWISE a few hours ago from the International Space Station. He says that the dust tail looks very good from there. It is worth enlarging the image.

So I actually did the calculations and the surface area of Jupiter could probably fit around 11,474,491,000,000 football fields.

Okay so I googled it and the radius of Jupiter is 43,441 miles. However, I’m going to convert that into meters, which’ll make that radius a cool 69,911,513 m. Next up I’ll plug that into the surface area of a sphere formula (A= 4πr^2) which will get us approximately 6.14 x 10^16 m^2 (or roughly 61,400,000,000,000,000 m^2).

Next, I found the area of one football field to be around 5,351 m^2. Dividing the surface area of Jupiter by the surface area of one football field, we can find out how many football fields will fit onto the surface of Jupiter. And that is 1.1474491 x 10^13. Calculating that, that will be 11,474,491,000,000 football fields (11 trillion or so). Oh boy.

For comparison’s sake, the universe is estimated to have AT MOST 2 trillion galaxies! Which means that Jupiter likely could fit more football fields than the universe has galaxies. Another example, there are an estimated billion trillion stars in the observable universe. Jupiter’s football fields account for half of the stars in our observable universe.

I actually tried to find out how many football fields were in the U.S. for comparison but I still can’t find a statistic. 

But also that’s pretty hilarious xD

They haven’t figured it out

Woah :O

COOOOOLLL

I’ve never gotten to see a full solar eclipse, just a partial one that happened a few years ago. 

Maybe I’ll have better luck in the future?

Traveling for 4 days, Just to See 30 Seconds of The Full Annular Eclipse! It Was worth All the Effort!

I’m so hype for this telescope though

They say it might be able to see back to when the first stars were born - how exciting!

Eat shit Hubble telescope

The launch of the James Webb Telescope – the successor of the Hubble Telescope – has been delayed until 2021 but damn it’s going to be awesome.

It’s alive ALIVE!!!!!

Hubble Takes Closer Look at Not-So-‘Dead’ Neighbor : Because they lack stellar nurseries and contain mostly old stars, elliptical galaxies — Like Messier 110 — are often considered “dead” when compared to their spiral relatives. But scientists have spotted signs of a population of young, blue stars at Messier 110’s center, hinting that this neighbor of our Milky Way may not be so “dead” after all. (via NASA)

Galileo, what a man
