Deep space, as taken by @nasa in the @nasahubble space telescope. Each poing is a galaxy, each with 100 billion stars, many of them with their own planers. Watching this photograph is like looking at the past, and it certainly puts things into perspective. In the words of Carl Sagan “The cosmos is all that is, or ever was, or ever will be.” Photograph is part of the public domain. #space #cosmos #interstellar #interstellarspace #stars #star #galaxy #galaxies #nasa #hubble #hubblespacetelescope #telescope #telescopes #astronomy #astrophotography #astrophysics #nature #natureza #naturepic #naturelove #natureporn #naturephotography #nature_perfection #naturegram #natureaddict #naturelovers #science #naturepics

"The world is like a ride at an amusement park, and when you choose to go on it, you think it's real, because that's how powerful our minds are. And the ride goes up and down and round and round and it has thrills and chills and it's very brightly colored and it's very loud. And it's fun, for a while. Some people have been on the ride for a long time, and they begin to question: 'Is this real? Or is this just a ride?' And other people have remembered, and they come back to us and they say 'Hey! Don't worry, don't be afraid -- ever -- because... this is just a ride.' And we kill those people. 'Shut him up! We have a lot invested in this ride! Shut him up! Look at my furrows of worry; look at my big bank account, and my family. This has to be real.' It's just a ride. But we always kill those good guys who try and tell us that -- ever notice that? -- and we let the demons run amok. But it doesn't matter, because... it's just a ride, and we can change it any time we want. It's only a choice. No effort. No worry. No job. No savings and money. Just a choice, right now, between fear and love. The eyes of fear want you to put bigger locks on your door, buy bigger guns, close yourself off. The eyes of love, instead, see all of us as one. Here's what we can do to change the world, right now, into a better ride. Take all that money we spend on weapons and defense each year and, instead, spend it feeding, clothing and educating the poor of the world, which it would do many times over -- not one human being excluded -- and we can explore space together, both inner and outer, forever. In peace." - Bill Hicks. // came across this yesterday and it spoke to me on a very deep level so I felt I had to share both the video (on my story) and in a way that I think reflects the scope of the idea too (in the form of a picture)

Rings of brilliant blue stars encircle the bright, active core of this spiral galaxy, whose monster black hole is blasting material into space at over 14 million kilometres per hour. Viewed nearly face-on, the galaxy, called Markarian 817, shows intense star-forming regions and dark bands of interstellar dust along its spiral arms. Observations by the new Cosmic Origins Spectrograph (COS) aboard the NASA/ESA Hubble Space Telescope captured the powerful outflow of material from this galaxy. The COS spectrum of Markarian 817 highlights the outflow's dynamic nature. A gas cloud containing hydrogen that was detected in Hubble data taken in 1997 does not appear in the COS observation because the cloud has apparently been driven out by an outflow of material from the galaxy. This discharge is being powered by a huge disc of matter encircling the supermassive black hole, which is 40 million times more massive than our Sun. The disc is driving the material out of the galaxy through powerful winds, produced by streams of charged particles. Some of the outflow rains back onto the galaxy. The rest settles into the intergalactic gas. Astronomers want to know how much of the outflow lands in the galaxy and how much escapes into intergalactic space. To achieve this, they need high-quality spectroscopic observations to detect the signatures of the outflowing material, which includes carbon, nitrogen and oxygen. This will allow them to determine the composition, location and dynamics of the winds that distribute the material. Markarian 817 is 430 million light-years away in the northern constellation of Draco. COS observed the galaxy on 4 August 2009, using its far-ultraviolet detector to distinguish the outflow from the galaxy’s core. NASA astronauts installed COS during Servicing Mission 4 in May to upgrade and repair the 19-year-old Hubble. The Hubble image was taken with the Wide Field Camera 3 on 2 August 2009. The composite image was made by using filters that isolate light from the blue, green and infrared portions of the spectrum, as well as emission from glowing hydrogen.

Via @sciencehumanist - In this stunning vista, based on image data from the Hubble Legacy Archive, distant galaxies form a dramatic backdrop for disrupted spiral galaxy Arp 188, the Tadpole Galaxy. The cosmic tadpole is a mere 420 million light-years distant toward the northern constellation Draco. Its eye-catching tail is about 280 thousand light-years long and features massive, bright blue star clusters. One story goes that a more compact intruder galaxy crossed in front of Arp 188 - from right to left in this view - and was slung around behind the Tadpole by their gravitational attraction. During the close encounter, tidal forces drew out the spiral galaxy's stars, gas, and dust forming the spectacular tail. The intruder galaxy itself, estimated to lie about 300 thousand light-years behind the Tadpole, can be seen through foreground spiral arms at the upper right. Following its terrestrial namesake, the Tadpole Galaxy will likely lose its tail as it grows older, the tail's star clusters forming smaller satellites of the large spiral galaxy.

Messier 7 (M7), noto anche come l'ammasso di tolomeo, è un brillante ammasso aperto nella costellazione di Scorpione . Il cluster si trova a una distanza approssimativa di 980 anni luce dalla Terra. Ha la designazione NGC 6475 nel Nuovo Catalogo Generale. Con una magnitudine visiva di 3,3 e un diametro apparente di 80 minuti d'arco - più del doppio della dimensione apparente della Luna piena - il Clolemy's Cluster è un facile bersaglio a occhio nudo. Messier 7 può essere visto vicino al pungiglione dello scorpione celeste. Il cluster è l'oggetto Messier più a sud nel cielo, il che lo rende un oggetto stimolante per chi si trova nelle latitudini settentrionali, in quanto la costellazione dello Scorpione non sale mai molto in alto sopra l'orizzonte. Messier 7 (M7), also known as Ptolemy’s Cluster, is a bright open cluster in Scorpius constellation. The cluster lies at an approximate distance of 980 light years from Earth. It has the designation NGC 6475 in the New General Catalogue. With a visual magnitude of 3.3 and an apparent diameter of 80 arc minutes – more than twice the apparent size of the full Moon – Ptolemy’s Cluster is an easy naked-eye target. Messier 7 can be seen near the stinger of the celestial scorpion. The cluster is the southernmost Messier object in the sky, which makes it a challenging object for those in northern latitudes as Scorpius constellation never rises very high above the horizon. #hubblespacetelescope #messier

“you’re a catalyst to your own happiness you know” 🎶 @thechainsmokers simple but profound line... I created my dreamscape series originally to express how I was feeling with the relationships that were falling apart in my life- This one in particular refers to my relationship with God and myself, that was wavering over the years, this line hit home. And this image is the manifestation of that line which coincided simultaneously with the moment I began to understand my own happiness and where the metaphysical principles of the archetypal character of Jesus fit into my life both in idea but more so in PRACTICE through actions. Music has been one of my biggest inspirations and affected the outcomes of my art and life immensely. Not sure if any of this really makes that much sense but I just felt like sharing 🙌🌌 . . . . #dreamscape #photoshop #astrophotography #digitalart #artistsoninstagram #space #hubble #astrophysics #astrophysics_ #hubblespacetelescope #bubblenebula #nebula #photomanipulation #nightphotography #milkywaychasers #plotograph #animation #followyourstars #blazingheavens #stargazing

Streaming out from the centre of the galaxy M87 like a cosmic searchlight is one of nature's most amazing phenomena, a black-hole-powered jet of electrons and other sub-atomic particles traveling at nearly the speed of light. In this Hubble telescope image, the blue jet contrasts with the yellow glow from the combined light of billions of unseen stars and the yellow, point-like clusters of stars that make up this galaxy. Lying at the centre of M87, the monstrous black hole has swallowed up matter equal to 2 billion times our Sun's mass. M87 is 50 million light-years from Earth.

Don’t be fooled! The cosmic swirl of stars in this NASA/ESA Hubble Space Telescope image may seem tranquil and unassuming, but this spiral galaxy, known as ESO 580-49, actually displays some explosive tendencies. In October of 2011, a cataclysmic burst of high-energy gamma-ray radiation — known as a gamma-ray burst, or GRB — was detected coming from the region of sky containing ESO 580-49. Astronomers believe that the galaxy was the host of the GRB, given that the chance of a coincidental alignment between the two is roughly 1 in 10 million. At a distance of around 185 million light-years from Earth, it was the second-closest gamma-ray burst (GRB) ever detected.

@Regranned from @sciencehumanist - Near the outskirts of the Small Magellanic Cloud, a satellite galaxy some 200 thousand light-years distant, lies 5 million year young star cluster NGC 602. Surrounded by natal gas and dust, NGC 602 is featured in this stunning Hubble image of the region. Fantastic ridges and swept back shapes strongly suggest that energetic radiation and shock waves from NGC 602's massive young stars have eroded the dusty material and triggered a progression of star formation moving away from the cluster's center. At the estimated distance of the Small Magellanic Cloud, the picture spans about 200 light-years, but a tantalizing assortment of background galaxies are also visible in the sharp Hubble view. The background galaxies are hundreds of millions of light-years or more beyond NGC 602.

nasaOne of the two galaxies seen here by the Hubble Space Telescope ( @nasahubble) is emitting the same microwaves as your kitchen appliance. Microwaves are actually produced by a multitude of astrophysical sources, including strong emitters known as masers (microwave lasers), even stronger emitters with the somewhat villainous name of megamasers and the centers of some galaxies. The lower, blue-tinted galaxy is a special kind of megamaser. The galaxy’s active galaxtic nucleus pumps out huge amounts of energy, which stimulates clouds of surrounding water. Water’s constituent atoms of hydrogen and oxygen are able to absorb some of this energy and re-emit it at specific wavelengths, one of which falls within the microwave regime.

A view of the Crab Nebula in X-Ray wavelengths made by the NASA Chandra X-Ray Observatory. This is how the inside of the nebula looks in X-ray wavelengths.⠀ ⠀ From the NASA website: "In 1054 AD, Chinese astronomers and others around the world noticed a new bright object in the sky. This “new star” was, in fact, the supernova explosion that created what is now called the Crab Nebula. At the center of the Crab Nebula is an extremely dense, rapidly rotating neutron star left behind by the explosion. The neutron star, also known as a pulsar, is spewing out a blizzard of high-energy particles, producing the expanding X-ray nebula seen by Chandra. In this new image, lower-energy X-rays from Chandra are red, medium energy X-rays are green, and the highest-energy X-rays are blue.⠀ ⠀ Image credit: NASA/CXC/SAO⠀ ⠀ ⠀ #astronomy #astrophotography #astrophotos #astro #nightsky #milkyway #galaxy #universe #cosmos #longexposure #nature #landscape #night #sky #beautiful #space #nightimages #stars #science #hubblespacetelescope #hubble #hst #universetoday #NASA #ESA #STSI #spitzerspacetelescope #nasachandraxray @nasachandraxray

Compared to the other fundamental forces in the Universe, gravity is fairly weak. Despite this, gravity has an influence over huge distances and is the driving force behind the motions of the most massive objects in the cosmos. The scattered and warped appearance of the galaxy in this image, NGC 4490, is a prime example of the results of gravity’s unrelenting tug. In this image, this most intense period is already over and the two galaxies have moved through each other, untangled themselves, and are speeding apart again. But gravity’s pull is relentless; the galaxies are likely to collide again within a few billion years. Together NGC 4490 and NGC 4485 form the system Arp 269, which is featured in the Atlas of Peculiar Galaxies. They are located 24 million light-years from Earth in the constellation of Canes Venatici (The Hunting Dogs). The extreme tidal forces of their interaction have determined the shapes and properties of the two galaxies. Once a barred spiral galaxy, similar to the Milky Way, NGC 4490’s outlying regions have been stretched out, resulting in its nickname of the Cocoon Galaxy. Virtually no trace of its past spiral structure can be seen from our perspective, although its companion galaxy NGC 4485 — not pictured here — still clings on to its spiral arms. This cosmic collision has created rippling patches of higher density gas and dust within both galaxies. The conditions there are ripe for star formation; the brilliant pink pockets of light seen here are dense clouds of ionised hydrogen, glowing as they are irradiated with ultraviolet light from nearby young, hot stars. Star formation is also evident in the thin thread that connects the two galaxies: a bridge of stars created by the ancient crash, stretching over the 24 000 light-years that currently separate the fated pair. But where there is life, there is also death. Several supernovae have also been spotted in NGC 4490 over the past few decades, including SN 1982F and SN 2008ax.
