If there was a sci-fi novel with a megalomaniac billionaire who was the son of an Apartheid emerald mine owner, and he was privatizing space exploration so the public no longer has a say in it...you know that would be considered bad, right? The heroes would fight to stop SpaceX.
The fact that anyone considers SpaceX as anything other than a continuation of the transfer of public sector science, that was run for the public good, into the hands of billionaires is a testament to our propaganda. Having space exploration controlled by one billionaire is bad.
Remember in the 60s when rockets launched and the credit was given to the scientists and astronauts that actually made it happen?
Now it's given to the billionaire who pillaged NASA tech and is now using it as his playground and promotion for his cars. That's bad. SpaceX is bad.

Chart-Topping Space Images From 2019 You Won’t Want to Miss
From the first-ever image of a black hole, to astronaut Christina Koch breaking the record for the longest single spaceflight by a woman – 2019 was full of awe-inspiring events! 
As we look forward to a new decade, we’ve taken ten of our top Instagram posts and put them here for your viewing pleasure. With eight out of ten being carousels, be sure to click on each title to navigate to the full post. 
1. First-Ever Black Hole Image Makes History 
Tumblr media
In a historic feat by the Event horizon Telescope and National Science Foundation, an image of a black hole and its shadow was captured for the first time. At a whopping 3.4 million likes, this image takes home the gold as our most loved photo of 2019. Several of our missions were part of a large effort to observe this black hole using different wavelengths of light and collect data to understand its environment. Here’s a look at our Chandra X-Ray Observatory’s close-up of the core of the M87 galaxy with the imaged black hole at its center.  
2. Hubble Celebrates 29 Years of Dazzling Discoveries
Tumblr media
Tumblr media
When you wish upon a star… Hubble captures it from afar ✨On April 18, 2019 our Hubble Space Telescope celebrated 29 years of dazzling discoveries, serving as a window to the wonders of worlds light-years away. ⁣
Hubble continues to observe the universe in near-ultraviolet, visible, and near-infrared light. Over the past 29 years, it has captured the farthest views ever taken of the evolving universe, found planet-forming disks around nearby stars and identified the first supermassive black hole in the heart of a neighboring galaxy. ⁣Want more? Enjoy the full 10 photo Instagram carousel here. 
3. Stars and Stripes in Space for Flag Day 
Tumblr media
Tumblr media
Patriotism was in the air June 14 for Flag Day, and coming in at number three in our most liked Instagram line up is a carousel of our stars and stripes in space! One of the most iconic images from the Apollo 11 missions is of Buzz Aldrin saluting the American flag on the surface of the Moon. But did you know that over the years, five more flags joined the one left by Apollo 11 – and that many other flags have flown onboard our spacecraft? Scroll through the full carousel for flag day here. 
4. Spitzer Celebrates its Super Sweet 16! 
Tumblr media
Tumblr media
Since 2003, our Spitzer Space Telescope has been lifting the veil on the wonders of the cosmos, from our own solar system to faraway galaxies, using infrared light! Thanks to Spitzer, we've confirm the presence of seven rocky, Earth-size planets, received weather maps of hot, gaseous exoplanets and discovered a hidden ring around Saturn. In honor of Spitzer's Sweet 16 in space, enjoy 16 jaw-dropping images from its mission here. 
5. Earth as Seen Through Our Astronauts’ Eyes Show  Perspective Changing Views
Tumblr media
“That's here. That's home. That's us.” – Carl Sagan
Seeing Earth from space can alter an astronauts’ cosmic perspective, a mental shift known as the “Overview Effect.” First coined by space writer Frank White in 1987, the Overview Effect is described as a feeling of awe for our home planet and a sense of responsibility for taking care of it. See Earth from the vantage point of our astronauts in a carousel of perspective-changing views here.
6. Astronaut Christina Koch Breaks Record for Longest Single Spaceflight by Woman 
Tumblr media
Tumblr media
Astronaut Christina Koch (@Astro_Christina) set a record Dec. 28, 2019 for the longest single spaceflight by a woman, eclipsing the former record of 288 days set by Peggy Whitson. Her long-duration mission is helping us learn how to keep astronauts healthy for deep space exploration to the Moon and Mars. Congrats to Christina on reaching new heights! Join in the celebration and view few photos she captured from her vantage point aboard the Space Station here. 
7. Our Beautiful Planet – The Only Place We Know to Harbor Life – From Space
Tumblr media
Tumblr media
Earth is special. It’s the only place in the universe that we know contains life. 
On July 7, 2019, two million people joined us in celebrating its beauty with a jaw dropping carousel of our home planet, as captured by crew members aboard the International Space Station. Bright blue oceans, glowing city lights and ice-capped mountain peaks come to life in a collection of breathtaking images, found here. 
8. A Moon Even Sinatra Couldn’t Help But Sing About
Tumblr media
Every 29 days our Moon turns over a new leaf, and on May, 18 we saw a very special one of its faces. Appearing opposite the Sun at 5:11 p.m. EDT, the world looked up to find a Blue Moon! Though the Moon didn’t actually look blue, the site of one is kind of rare. They occur on average about every two-and-a-half years when a season ends up having four full moons instead of three. Click through a carousel of high-definition lunar phases here. 
9. The Majesty of Hubble Imagery ... From Your Backyard
Tumblr media
Tumblr media
On December 23, a new gallery of Hubble Space Telescope images highlighting celestial objects visible to amateur and professional astronomers alike was released. All of the objects are from a collection known as the Caldwell catalog, which includes 109 interesting objects visible in amateur-sized telescopes in both the northern and southern skies. Flip through the jaw-dropping carousel here, and learn more about how you can study the night sky with Hubble here. 
10. The Moon Gets Sassy
Tumblr media
Nobody:
The Moon: “Y'all on the way yet?” 👀
We're working on it, Moon. Under the Artemis program, we're sending the first woman and the next man to walk on your surface by 2024. Find out how we’re doing it here.

Why not just buid a solar panel around the sun to solve all energy problemss?
Tumblr media
Behold the Dyson Sphere
Dyson sphere is a hypothetical mega-structure that completely encompasses a star and captures most or all of its power output.
Over the years many variants have been explored:
The simplest such arrangement is the Dyson ring, in which all ‘energy harvesting structures’ share the same orbit.
Tumblr media
Add multiple Dyson ring structures and you will get a Dyson swarm.
Tumblr media
Now what if you didn’t like a consistent orbit for your structures, you could employ a solar sail to continuously modify its orbit( called a statite ).
Such an arrangement would be known as a Dyson Bubble
Tumblr media
Then there is the fictionally popular version - The Dyson Shell, where a uniform solid shell of matter just encapsulates the entire star.
Tumblr media
And many many more. But you get the gist.
Could there be Dyson Spheres out there?
When scientists were monitoring the brightness from some stars, they found that it fluctuated in some odd ways like so:
Tumblr media
                          Brightness v/s time for KIC 8462852
It is common for such dips to occur since when a planet eclipses a star, there would a drop in the brightness observed from the star.
Tumblr media
                       Brightness v/s time for a binary star system
But what was baffling was the duration and period of occurrence of these dips.
Although the main line of rationale remains as asteroid impact remnants or interstellar collisions causing these aberrations in data.
Tumblr media
But to say that these could the signs of an alien civilization does remain to be the more entertaining interpretation.
Great Question. Thanks for asking !

Remember when we thought that the internet would enable the entirety of humanity’s knowledge to be available to everyone at their fingertips?
Yeah, we forgot that quantity is not quality, and that giving a voice to every grifter and stupid idiot might just be our undoing.

R.I.P. Opportunity. This was truly an amazing mission. It was supposed to last only 90 days. But the little rover kept, well, roving - for 15 years - and it probably would have kept going if not for a worldwide dust storm that pretty much shut it down last year (but they only gave up trying to contact it yesterday).
How much you want to bet if we ever get to Mars and if they travel out to where Opportunity is parked, the moment they brush grit off the solar panels the thing will spring back to life?

Happy 100th birthday to Katherine Johnson!
Johnson is an black American mathematician who’s work with orbital mechanics proved critical to the success of early NASA missions.  Her work included calculating trajectories, launch windows, and emergency return paths for Project Mercury, the rendezvous paths for the Apollo Command and Lunar Module on it’s trip to the Moon, and her work was pivotal during the development of the Space Shuttle program.
She was initially hired on at the National Advisory Committee for Aeronautics (NACA) as a human computer, but her knowledge of analytic geometry helped her move up to an aerospace technologist.  Once NACA was folded into NASA in 1958, Johnson worked in the Spacecraft Controls Branch, and she was often called by management to verify electronic computations.
In 2015, she was awarded the Presidential Medal of Freedom by President Barack Obama for her instrumental work with NASA.  In 2016, a brand new building at NASA’s Langley Research Center in Hampton, Virginia, was named after her.  The Katherine G. Johnson Computational Research Facility began operations in 2017.

Unveiling the Center of Our Milky Way Galaxy
Tumblr media
We captured an extremely crisp infrared image of the center of our Milky Way galaxy. Spanning more than 600 light-years, this panorama reveals details within the dense swirls of gas and dust in high resolution, opening the door to future research into how massive stars are forming and what’s feeding the supermassive black hole at our galaxy’s core.
Tumblr media
Among the features coming into focus are the jutting curves of the Arches Cluster containing the densest concentration of stars in our galaxy, as well as the Quintuplet Cluster with stars a million times brighter than our Sun. Our galaxy’s black hole takes shape with a glimpse of the fiery-looking ring of gas surrounding it.
The new view was made by the world’s largest airborne telescope, the Stratospheric Observatory for Infrared Astronomy, or SOFIA.

Fictional space vehicle
Sword of the Orion spacecraft visiting a small scientific and refueling outpost on Ophelia, one of the tiny moons of Uranus. With negligible surface gravity and abundance of water ice, this moon is a perfect place to produce valuable fuel for visiting spaceships, as well as conduct scientific observations of Uranus and search for Kuiper Belt objects.
As always, prints of this and other artworks are available in my society6.com and deviantART.com shops.
