Falcon Heavy Launch Close Up
Twenty seven Merlin rocket engines are firing in this close-up of the launch of a Falcon Heavy rocket. Derived from three Falcon 9 first stage rockets with nine Merlin rocket engines each, the Falcon Heavy left NASA's Kennedy Space Center launch pad 39A on April 11. This second launch of a Falcon Heavy rocket carried the Arabsat 6A communications satellite to space. In February of 2018, the first Falcon Heavy launch carried Starman and a Tesla Roadster.
Designed to be reusable, both booster stages and the central core returned safely to planet Earth, the boosters to Cape Canaveral Air Force Station landing zones. The core stage landed off shore on autonomous spaceport drone ship Of Course I Still Love You.1 -
NGC 2346: A Butterfly-Shaped Planetary Nebula
It may look like a butterfly, but it's bigger than our Solar System. NGC 2346 is a planetary nebula made of gas and dust that has evolved into a familiar shape. At the heart of the bipolar planetary nebula is a pair of close stars orbiting each other once every sixteen days.
The tale of how the butterfly blossomed probably began millions of years ago, when the stars were farther apart. The more massive star expanded to encompass its binary companion, causing the two to spiral closer and expel rings of gas. Later, bubbles of hot gas emerged as the core of the massive red giant star became uncovered.
In billions of years, our Sun will become a red giant and emit a planetary nebula - but probably not in the shape of a butterfly, because the Sun has no binary star companion.1 -

This is a “preplanetary” nebula called the Egg Nebula.
And it has nothing to do with eggs or planets, despite its name; it was created by a dying star shedding its outer layers.
These kinds of nebulae exist in this state for only a few thousand years as they evolve into planetary nebulae.
The dark bands and jutting white arms are material left over from a star that was not very different from our Sun.
Once the expiring star (hidden from view in the center by dust and debris) eventually stops spitting out material, its remaining core heats up.
Then the surrounding gas gets excited and set aglow and transitions into a planetary nebula, which again has nothing to do with planets; the name comes from its shape.1 -

Herschel's Cygnus X
The Herschel Space Observatory's infrared view of Cygnus X spans some 6x2 degrees across one of the closest, massive star forming regions in the plane of our Milky Way galaxy. In fact, the rich stellar nursery already holds the massive star cluster known as the Cygnus OB2 association. But those stars are more evident by the region cleared by their energetic winds and radiation near the bottom center of this field, and are not detected by Herschel instruments operating at long infrared wavelengths.
Herschel does reveal the region's complex filaments of cool gas and dust that lead to dense locations where new massive stars are forming. Cygnus X lies some 4500 light-years away toward the heart of the northern constellation of the Swan. At that distance this picture would be almost 500 light-years wide.1 -

Why does it freak you out?
You have to think of the implications of it. One, we are the only intelligent beings in the universe which is such a lonely thought.
The other is that it works as sort of evidence that we are actually living in some sort of simulation and nothing is actually real. When you compile this with the free will vs hard determinism debate it becomes even more of mindfck0 -

Dude, first, if you choose to do something you have free will. Also, statistically speaking, we aren't alone, just too far away to ever be able to travel to. So we are the best that we got.
And always remember, if the universe is truly infinite, mathematically speaking, there is an infinite number of life in the universe.1 -

There is no free will though. Everything you do or “choice” you make is the result of a previous string of events and external factors.
Just start observing your thoughts right now. Then just try stopping your thoughts. You actually can’t. So really, you cannot even stop that. If you actually understand what’s happen here then you realise that you don’t even have any control. One thought generates another, and so on...and so on... you cannot get to the actual origin of this either.
That’s what the paradox is perplexing. Infinite universe, infinite possibilities. The possibility for one alien life to master ftl travel and map the universe but we haven’t met them yet.0 -

Anything that happens in an infinite scenario happens infinity times. Also, touch your nose. Either you chose to or not, but it had nothing to do with anyone other than you.0 -

Actually it has a lot to do with you and then a partially with me because you replied to me....could trace this back further and further if we really wanted to. So I yes I might touch my nose but then I won’t either. Breaking most things down it gets rather binary but either way, one of those scenarios will go down but that doesn’t really imply I was the one in control of if it. It was just gonna happen anyway.
I’m gonna be lazy and just drop a YouTube video here. Interesting stuff.

You could also argue the length of time humanity has and will exist on Earth is such a small blip in time to the length of time the universe has and will exist so others of the same or higher intelligent existing at the exact same blip of time could be unlikely.
As far as free will, wouldn't realizing there is no free will be...freeing? Nothing you do truly matters so do what makes you happy?
Yeah that sounds like Absurdism, enter Camus. There horrible truth is that pretty much all our moral foundations are forged in the pretext that we do have free will. The illusion must be sustained. It’s utterly terrifying when you think about it.0 -

Formation of the Southern Crab Nebula
In celebration of the 29th anniversary of the launch of NASA's Hubble Space Telescope on April 24, 1990, astronomers captured an image of the tentacled Southern Crab Nebula.
The nebula, officially known as Hen 2-104, is located several thousand light-years from Earth in the southern hemisphere constellation of Centaurus. It appears to have two nested hourglass-shaped structures that were sculpted by a whirling pair of stars in a binary system. The duo consists of an aging red giant star and a burned-out star, a white dwarf. The red giant is shedding its outer layers. Some of this ejected material is attracted by the gravity of the companion white dwarf.
The result is that both stars are embedded in a flat disk of gas stretching between them. This belt of material constricts the outflow of gas so that it only speeds away above and below the disk. The result is an hourglass-shaped nebula.
This artist's impression of the formation of Southern Crab nebula illustrates its hourglass-shared structure, that has been created by the interaction between a pair of stars at its center: a red giant and a white dwarf. The red giant is shedding its outer layers in the last phase of its life before it too lives out its final years as a white dwarf.1 -
The Shape of the Southern Crab
The symmetric, multi-legged appearance of the Southern Crab Nebula is certainly distinctive. About 7,000 light-years distant toward the southern sky constellation Centaurus, its glowing nested hourglass shapes are produced by the remarkable symbiotic binary star system at its center.
The nebula's dramatic stellar duo consists of a hot white dwarf star and cool, pulsating red giant star shedding outer layers that fall onto the smaller, much hotter companion. Embedded in a disk of material, outbursts from the white dwarf cause an outflow of gas driven away both above and below the disk resulting in the bipolar hourglass shapes. The bright central shape is about half a light-year across.
This new Hubble Space Telescope image celebrates the 29th anniversary of Hubble's launch on April 24, 1990 on board the Space Shuttle Discovery.

Pan-STARRS Across the Lagoon
Ridges of glowing interstellar gas and dark dust clouds inhabit the turbulent, cosmic depths of the Lagoon Nebula. Also known as M8, the bright star forming region is about 5,000 light-years distant. But it still makes for a popular stop on telescopic tours of the constellation Sagittarius, toward the center of our Milky Way Galaxy. Dominated by the telltale red emission of ionized hydrogen atoms recombining with stripped electrons, this stunning view of the Lagoon is over 100 light-years across.
At its center, the bright, compact, hourglass shape is gas ionized and sculpted by energetic radiation and extreme stellar winds from a massive young star. In fact, the many bright stars of open cluster NGC 6530 drift within the nebula, just formed in the Lagoon several million years ago. Broadband image data from Pan-STARRS (Panoramic Survey Telescope & Rapid Response System) was combined with narrowband data from amateur telescopes to create this wide and deep portrait of the Lagoon Nebula.1 -
