Say hello to this cosmic beauty called #NGC6744. This #spiral #galaxy is 175,000 (ly) #lightyears across and only 30 million ly (~10 million parsecs) away from Earth in the #constellation #Pavo. It’s bigger than our own galaxy and a supernova was discovered there in 2005. #astronomy #nasa #hubble #astrophotograhy
Here is an awesome image of #Arp147 (right) that contains a spiral #galaxy that collided with the #elliptical galaxy on the left. What’s truly stunning is a ring of #blackholes can be seen around the pink galaxy. The collision produced an expanding wave of star formation that shows up as a blue ring.
These stars race through stellar evolution and explode as #supernovas, leaving behind a #neutron #stars or black holes.

Looking underneath a #Soyuz #rocket! This is what #NASA has been using to get up to the #ISS until their rocket is ready. It costs $80 million PER seat. Their rockets have been so effective that NASA has even used them for some of their designs. Now, tensions are tight between the U.S and Russia and ties may be cut for 2020 if no resolution is made up. #astronomy
"WE ARE DEAD STARS…looking back up at the sky. Everything you are, literally the iron in your blood, comes from the instant before a star dies. In the case of the most massive stars, the core of the star collapses and sets off the most violent, brilliant reaction we know of called a supernova reaction. Everything outside the element iron, everything heavier, all the gold, all the silver, all the lead, all the uranium - that’s formed in that supernova explosion. A single star will glow as brightly as an entire galaxy, as hundreds of billions of stars, in that moment of death and and that’s what you are. That is literally what your body is, that instant of death.”
New #Camelopardalids meteor shower tonight! #Comet 209P/Linear will be passing by Earth and debris falling off its tail will fall on Earth tonight. You can see up to 100 meteors per hour! LOOK North (or find the North Star) between 2a -4a EST. Next weekend you’ll actually get to see the comet itself if you have a small telescope. Enjoy! #astronomy #meteorshower
This is the #Antennae #Galaxy or also known as #NGC4038. They are located 45 million light years away from Earth in the #constellation #Corvus. Take a good look because you are looking at a snap shot of what happens when two galaxies collide! This process started about 1.2 billion years ago when two separate galaxies were traveling through space. Then 600 million years later both galaxies were locked into this collision course. The actual collision itself happened 300 million years later, but in another 400 million years these two galaxies will soon turn into a single core and form an elliptical galaxy. A fun fact is that most galaxies undergo at least one collision like this. Even our Milky Way is on a collision course with Andromeda right now! Don’t worry though our Sun will be long gone before then… oh and Earth! Haha but not for at least 5 billion years ; ) #astronomy #science #space #universe
Here’s the gorgeous Rosette Nebula or Caldwell 49. This beauty is about 5,200 light years away and about 130 light years in diameter! I couldn’t pick just one image so I gathered a few more for you.
Note: Some images have different colors which is just the nebula taken in different filters to bring out what elements are present. For example, red is sulfur, green is hydrogen, and blue oxygen. Enjoy!
Since I’ve been learning astronomy or cosmology I have been inspired by so many things, such as galaxies, black holes, stars, or even planets. However, today someone really inspired me. A 13 year old girl named Alyssa Carson who wants to become an astronaut one day and be the first person to walk on Mars.
Here are 5 reasons why I think everyone should know this girl:
1. She’s the first person to complete all NASA Space Camps
2. Alyssa not only knows French, Spanish, Chinese, and some Turkish but studies schools subjects in those languages!
3. Alyssa is also the first person to complete NASA’s Passport Program visiting all 14 locations!
4. Alyssa not only wants to become an astronaut but gives motivational speeches to children
5. Instead of taking a summer off Alyssa will be going to more Space Camps, TED Talks, and much more (check out my blog post for her crazy hectic schedule!)
I wrote up a full blog post an expanding a little more on those 5 reasons of why this young girl has inspired me and may even inspire you.

Today in 1970 #Apollo 13 launched the 3rd crewed mission to the moon. The mission was aborted because an oxygen tank exploded two days later, crippling the Service Module, which the Command Module depended on.
Despite great hardship caused by limited power, loss of cabin heat, shortage of portable water, and the critical need to jury-rig (makeshift repairs) the carbon dioxide removal system, the crew returned safely to Earth on April 17th.
