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.

Ever wondered how planets are formed? Here’s what happens:
1. A star is born from a collapsing cloud of dust, gas within a larger cloud, called a nebula.
2. The ring of dust and gas gets exceedingly more compressed and starts to rotate all in the same direction. It thins out and gets flatter and forms what astronomers call a "protoplanetary disk"
3. Then this is where the cosmic gallery really heats up as rocks collide with each other to form larger ones. They soon start to shape into the beginnings of planetestimals
4. In the inner disk most of the gas has been gobbled up by the star, which leads to the formation of smaller rocky planets closer to the star. This additional material in the outer area of the disk allows the planetesimals farther from the star to grow larger as it accumulates dust, gas, and ice.
5. _Hundreds of these planetesimals_ are forming at the same time. It also means that they inevitably meet up and collide! Some collide hard and fast, others slowly mend together over time, and others are far enough for gravity to throw them across lanes of traffic.
6. After millions of years of countless encounters and collisions the dust starts to settle and you are left with many larger and fewer planets that dominate their area.

This is called the "Draco Trio" which is located about 100 million light years away. It’s rare to 2 barred spiral galaxies at different angles. From left to right we have NGC 5981, NGC 5982, and NGC 5985. Astronomer SimÃµes Lopes has said that NGC 5292 could be harboring a supermassive black hole and not only that but there may be a quasar in the mix! Nonetheless, it’s hard to fathom that we are looking incredibly large objects in space that are unfathomably far apart, and all right next to each other. There are even some galaxies in the background as well!

You may be familiar with the famous galaxy called Andromeda (M31)that’s 2.5 million light years away from Earth. However, did you know that scientist have counted 20 satellite galaxies swarming around Andromeda? It doesn’t stop there. Researchers from the Niels Bhor Institute (and among others) have discovered something particular interesting with the satellite galaxy called Andromeda II.
Researchers detected a string of stars acting very differently from the rest of the stars around it. They later discovered that it was a remnant of a merger between 2 dwarf galaxies. This was a first time for astronomers to see a remnant of a merger between such low mass galaxies. To give you an idea of how low it is, Andromeda II is only 1% of the Milky Way.

Here’s one of my favorite images of the Tulip Nebula (Sh2-101). This nebula is about 8,000 light years away and has a gorgeous O star glowing bright called HDE 227018, which is right in the middle of this image near the blue arc. I just find this image incredibly beautiful and it’s also in close proximity to Cygnus X-1 which is one of the first suspected black holes!

What is a pulsar? Well think of a pulsar as an endpoint to a stellar evolution. A neutron on its own is already intense with rotating speeds of 642 times per second! However, when the rotational axis of the star and magnetic axis are misaligned things start to get incredibly intense. When that starts to happen an intense electric field that outputs over 1 trillion volts is born! To put that in perspective if you took one single cubic meter of this field, it outputs more energy than humans have ever produced to this day. Pulsars are incredibly dangerous and can be thought of as cosmic light houses. It’s even scarier when they are pointed at Earth!

This is one of the most gorgeous photos called NGC 6302 or the"Butterfly Nebula." This beauty is about 2,200 light years away from Earth and located right in our own Milky Way. The gasses you see here are travelling at about 1 million km per hour!
You can’t see it right away but there is a dying star right smack in the middle. This star is 5 times the mass of our own Sun and is considered to be one of the hottest stars in our Milky Way. The surface temperature is about a scorching 222,204 C or 400,000 F. Our Sun’s surface temperature is about 5,526 C or 9,980 F, so just imagine the hottest day you’ve experience and multiply that by 40! It’ll give you a tiny bit of perspective.

Today NASA’s Kepler mission announced a significant discovery of 715 newly-confirmed planets. What’s really interesting is that 95% of these planets are smaller than Neptune or 24,622 km (15,299 miles). Astronomers found even more fantastic news and saw that 4 of these planets were 2.5 times bigger than Earth and lay in the habitable zone.
These newly discovered planets orbit around 305 stars and many have multiple star systems. It’s important for astronomers to study these multiple planet systems because they’re fertile grounds for understanding planet formation. Since the first discovery of a planet outside our solar system 2 decades ago, Kepler has been increasing their methods of verifying planets even faster. It’s only a matter of time until we answer the aged old question: “Are we alone in the universe?”
A beautiful image of NGC 6188 displaying the curves and shapes lit up by the glowing hydrogen gas. This is located 4000 light years away from Earth and display young hot massive stars that sculpt the dark shapes seen here. The recent star births were likely triggered by winds and supernova explosions.
Joining this beautiful cosmic canvas is the rare emission nebula NGC 6164. You can see a bright star on the bottom right which was created by a massive O star type that is at least 40 times massive than our sun.
The appearance of the new “star” in the sky helped revise the ancient models of the heavens and to move forward by realizing there needed to be more accurate astrometric catalogues, as well as better instruments for observing. Not only that but it also challenged the Aristotelian dogma of the unchangeability of the realm of stars.
The supernova left behind a fierce hot cloud of expanding debris, which is in yellow and green. You’ve also may have noticed the blasts outer shock wave, which is illuminated all around like a blue sphere of ultra-energetic electrons. Last but not least the newly synthesized dust in the ejected material and heated dust from before from the area around the supernova radiate at 24 microns. which is in red.
My blog post on supernova’s if you want to learn a little more:http://www.brownspaceman.com/have-you-seen-a-picture-of-a-supernova/
This is the stunning image of the debris of an exploded star known as supernova remnant 1E 0102.2-7219 (E0102 for short). This was taken by NASA’s Chandra X-ray observatory and E0102 is located about 190,000 light years away, tucked in the small Magellanic Cloud, which is one of the nearest galaxies to the Milky Way.
It happened when a star much more massive than the sun exploded, which if you were here a 1000 years ago on Earth in the southern hemisphere you would be able to see this in the sky!
In this image the lowest-energy X-rays are colored orange, the intermediate range of X-rays is cyan, and the highest-energy X-rays Chandra detected are blue. An optical image from Hubble Space Telescope (in red, green, blue) shows additional structures in the remnant and also shows foreground stars in the field.
