Callisto, Io And Europa. Jupiter’s Moons

“In celebration of the twenty-first anniversary of the Hubble Space Telescope’s deployment in April 2011, astronomers at the Space Telescope Science Institute pointed Hubble’s eye to an especially photogenic group of interacting galaxies called Arp 273.

The larger of the spiral galaxies, known as UGC 1810, has a disk that is tidally distorted into a rose-like shape by the gravitational tidal pull of the companion galaxy below it, known as UGC 1813. A swath of blue jewels across the top is the combined light from clusters of intensely bright and hot young blue stars. These massive stars glow fiercely in ultraviolet light.

The smaller, nearly edge-on companion shows distinct signs of intense star formation at its nucleus, perhaps triggered by the encounter with the companion galaxy.”

This is Earth, our amazing home. The only planet in the solar system with the ability to harbor life (that we know of).

This is the distance between our awesome planet and the moon. 

Doesn’t look that far does it? How about if I told you that you could fit EVERY planet in our solar system neatly in that distance. 

Speaking of the other planets in our solar system, this is them & this is where our amazing planet resides.

The moon’s our cute little companion. This is the United States compared to it.

The planets in the solar system are so cool. This is what North America looks like in comparison to Jupiter. 

Speaking of Jupiter and the moon, this is what it would look like if Jupiter was in the place of the moon. (The white dot is our moon). 

Earth compared to Saturn (well 6 Earths…)

Ever wonder about what Earth would look like if it had rings like Saturn? Well wonder no more.. 

Amazing right? Want to see something cooler? Here is the Earth compared to our Sun. 

Here’s what we look like from the moon

And from Mars

From Saturn 

From Neptune…

Here is what the Sun looks like from Mars

Remember what Carl Sagan said? There are more stars in space than grains of sand on every beach in the Earth. 

That’s a lot right? That only means there are stars way larger than our Sun..like this one for example: 

And there are stars bigger than that….

Stars are huge, but the galaxy is even bigger. If you shrunk the Sun down to the size of a white blood cell, the Milky Way Galaxy would be the size of the United States. 

This is where the Earth is in our huge galaxy 

You know all the stars we see in the sky? These are the ones we only ever see (this isn’t our galaxy but its very similar)

The Milky Way is so big that the last time the Earth was in this exact position in the galaxy, the dinosaurs were here

Even though our galaxy is huge, there are galaxies that are even bigger…

This picture from Hubble shows thousands of thousands of thousands of galaxies that each have their own stars with their own planets…

Here is one of the galaxies in that picture. It is 10 BILLION light years away. When we look at it, we are looking 10 BILLION YEARS BACK IN TIME

And just to keep this in mind, this is a very small portion of the sky that was believed to be empty…

Everything is relative. 

Next time you’re stressed out or worried about something, stop and take a step back. Look up at the sky and think about all of the things that are out there. All the stars being born, the stars dying, galaxies colliding. 

We live in such an amazing universe, and we are only an extremely tiny part of it.
