For the second time in six years, a massive star exploded in the Whirlpool Galaxy. This star system lies about 23 million light-years from Earth toward the northern constellation of Canes Venatici. Actually a pair of galaxies locked in a gravitational embrace, the large spiral's structure resulted when the smaller companion came from behind and passed through its disk, As recently as 50 to 100 million years ago, a subsequent disk passage returned the smaller companion to slightly behind the larger spiral where we see it today.

Two beautiful and almost identical spiral galaxies in Virgo, imaged by the Gemini South telescope in Chile...

NGC5427 (the faced-on spiral galaxy at lower left) and its twin NGC 5426 (upper right). Together, they are known as Arp 271.

This violent encounter that will take 100 million years to complete. Over millions of years, the twin galaxies will pass each other, pull back, tangle again… this repeats several times, and finally they will end up as a large and featureless elliptical galaxy, leaving no sign that once upon a time they were a pair of beautiful spiral (except in our pictures on Earth, if we are still around…).

One last thought: The galaxies are 90 million light-years away from us, meaning that the image above was what they looked like 90 million years ago. Today, as we are admiring their beautiful spiral structures in the picture, in reality they may be so distorted that what was left is only a mess, gradually settling down to become an elliptical galaxy.

Supernova 1987A suddenly exploded on 23 February 1987 on the edge of a nearby dwarf galaxy called the Large Magellanic Cloud 168,000 light years away.

The event, which was visible with the unaided eye, was one of the nearest core collapse supernovae of modern times, giving scientists an opportunity to study the cataclysmic blast in unprecedented detail.

The new research, reported in the Astrophysical Journal, has detected signs of what could be a pulsar wind nebula driven by a spinning neutron star or pulsar.

The constellation of Virgo (The Virgin) is especially rich in galaxies, due in part to the presence of a massive and gravitationally-bound collection of more than 1300 galaxies called the Virgo Cluster. One particular member of this cosmic community, NGC 4388, is captured in this image, as seen by the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3.

Located some 60 million light-years away, NGC 4388 is experiencing some of the less desirable effects that come with belonging to such a massive galaxy cluster. It is undergoing a transformation and has taken on a somewhat confused identity.

While the galaxy’s outskirts appear smooth and featureless, a classic feature of an elliptical galaxy, its center displays remarkable dust lanes constrained within two symmetric spiral arms, which emerge from the galaxy’s glowing core — one of the obvious features of a spiral galaxy. Within the arms, speckles of bright blue mark the locations of young stars, indicating that NGC 4388 has hosted recent bursts of star formation.

The Red Spider Nebula is a planetary nebula located near the heart of the Milky Way, in the northwest of the constellation Sagittarius.
The nebula has a prominent two-lobed shape, possibly due to a binary companion or magnetic fields and has an ‘S’-shaped symmetry of the lobes – the lobes opposite each other appear similar. This is believed to be due to the presence of a companion to the central white dwarf. However, the gas walls of the two lobed structures are not at all smooth, but rather are rippled in a complex way.

Fireworks shows are not just confined to Earth’s skies. NASA’s Hubble Space Telescope has captured a spectacular fireworks display in a small, nearby galaxy, which resembles a July 4th skyrocket.

A firestorm of star birth is lighting up one end of the diminutive galaxy Kiso 5639. The dwarf galaxy is shaped like a flattened pancake, but because it is tilted edge-on, it resembles a skyrocket, with a brilliant blazing head and a long, star-studded tail.

Kiso 5639 is a rare, nearby example of elongated galaxies that occur in abundance at larger distances, where we observe the universe during earlier epochs. Astronomers suggest that the frenzied star birth is sparked by intergalactic gas raining on one end of the galaxy as it drifts through space.

This video using images from the NASA/ESA Hubble Space Telescope shows the rich galaxy cluster Abell 3827. The strange blue structures surrounding the central galaxies are gravitationally lensed views of a much more distant galaxy behind the cluster. Observations of the central four merging galaxies have provided hints that the dark matter around one of the galaxies is not moving with the galaxy itself, possibly implying dark matter-dark matter interactions of an unknown nature are occurring.

Twisted Galaxy
The spiral galaxy NGC 7714 has seen some tough times. About 100 million years ago it drifted too close to a galactic neighbor, and the two objects began a dramatic gravitational dance. This image, released on January 29 and snapped by the Hubble Space Telescope, shows how the galaxy has been transformed by its close encounter.

The graceful arms of NGC 7714 got twisted out of shape and dragged into long tails. During the interaction the galaxy also ripped material from its smaller companion, forming a hazy stream of matter that is being funneled into the bigger galaxy's core. The incoming matter is triggering the birth of huge new stars, lighting up the galaxy with sparkling bursts of blue

So science has made me sad. I began my physics PhD about two years ago and now I work with the Astronomy group (I use their fancy radio telescope to study geophysics. Not important). However recently I found out sad facts about nebula. I always imaged riding on star trek style FTL ship and blasting throug hnebula with all the bright colors and everything, but basically that's a lie. In general, the nebula are only bright becasue we are so far away from them. Think of a cloud and fog, you can see the cloud as a distinct object only becasue you are so far from it. Once inside it though, it disolves to a white mess. A nebula would be the same, it would only serve to cloud your vision of other objects, and even more so, since you are so close to it, and the emission so low, you wouldn't see anything but blackness. Even being really close to it, because the surface luminosity of the object is actually quite low, it would look like nothing but dust. Cold dark dust.

Bonus, most of those colors aren't real. Essentially all astronomy photos are taken in black and white at a single frequency, often a frequency outside of the normal sight range, and then color is added later to bring out some important aspect, such as a spectral line from a particular element. In real life, most everything is varying shades of white.

tl;dr: Life is terrible and meaningless, and space is an empty void

you forgot the part where what we are seeing thru the telescope is hundreds of lightyears away and already passed. While there is false color added, you would still not see what you see here even if FTL (instantaneous teleportation) did exist, because everything we see has already passed many many many years ago.

I don't completely agree however, that you would not see such wonders out of the USS Majestic's 20ft thick sapphire window, you would just be seeing a very far journey, back in time of another distant event that has long passed in another part of the universe.....

It'd just be another window, looking at a different piece of history of galactic events, from a different vantage point/perspective. Because really, being close enough to see one of these events (such as a vagrant white dwarf colliding with a class 3 supergiant at near lightspeed) would more than likely mean near-instantaneous death by gamma rays.

>Bonus, most of those colors aren't real.

They are real, kinda. It depends on what you mean by "real". Are the colours accurate representations of what we'd see with our own eyes? Nope, nor is that our goal. Are the colours just some fake artist's interpretation/rendition? Nope, absolutely not. The colours are absolutely in the data, they're objectively "real", they're just not mapped to our shitty meatbag eyes.

>Essentially all astronomy photos are taken in black and white ...

*ALL* digital photography is captured in greyscale. The Hubble Space Telescope and your cellphone are no different on this front - they both capture multiple greyscale images, which are subsequently *post-processed* into a single RGB colour image.

The main difference here is that your cellphone uses a Bayer filter (a grid of alternating red, green, and blue filters over the array) in order to capture all three of its required greyscale images at once. You lose some spatial resolution doing it this way (for each filter, you just mask out the pixels used by the other filters and interpolate over them), but you get to capture all three images at once. For astronomy, we care much more about spatial resolution, and most astronomical objects don't change much over the course of a few minutes anyway, so we take the time to capture full-frame images with separate filters. But otherwise, the process is fundamentally the same - multiple greyscale images are captured for post-processing into a single RGB colour image.
>>
>>2814646

>... at a single frequency ...

I'm being a bit picky with language, but this isn't true at all. There are a few common narrow band filters which are used for emission line work, but even these cover a small range of wavelengths/frequencies. The vast majority of images are captured using wideband filters, which cover huge swaths of wavelength space (~hundreds of nanometers). Note that the typical Bayer filters used by your cellphone are comparable in spectral width to our common wideband filters - a few hundred nanometers each.

>often a frequency outside of the normal sight range

Yep, this is often the case.
>>
>>2814646

>and then color is added later

Kinda. Colour is "added" in the exact same way colour is "added" to your cellphone's colour images. That is, the colour is merely a consequence of the ratio of each pixel's brightness as observed by the red, green, and blue filters.

The reason the Halpha regions in images like >>2814931 show up nice and red isn't because someone thought it would be nice if those little splodgy regions inside the galaxy were red, it's because Halpha emits strongly at a wavelength that is commonly covered by the *red* filter. Those pixels are nice and bright in the red image, and considerably less bright in the blue/green filters. The colours being displayed might not directly map to our own eyes, but they're 100% real in the sense that they're a *direct* consequence of the observed data. All the visual information you're being shown is real and physically interpretative.

People get this idea in their head that we're just arbitrarily colouring in different parts of the images, as if we're just using the Brush tool in Photoshop (I'm not saying this is what you're saying, this just tends to be a common misinterpretation when people talk about how the colours are "fake"). This isn't what's happening at all.

What's more, the super common B, V and R (or u, g, r in newer systems) filters we use in astronomy are reasonably comparable to the standard R, G, B filters used in consumer grade Bayer filters. Most bright nebula/galaxies are common targets to amateur astrophotographers as well, so it's pretty easy to find images of many of these objects photographed using default DSLR's Bayer filters. So if you really care, you can search for comparison images.
>>
>>2814646

>In real life, most everything is varying shades of white.

Kinda, not really.

When you look through an amateur grade telescope, it's very rare to see any colour in most astronomical objects. You can maybe get a tiny bit of blueish green out of the M42 with a large Dob, but even that's a bit weak. But that's not because those objects don't have any inherent colour, it's just because they're *faint*. The rods in our eyes (which are sensitive to brightness) are much more sensitive than our cones (which are sensitive to colour), so faint objects look much more monochromatic. There's just not enough light to activate the cones. Take distinctly red, green and blue LEDs, put them in a totally dark and infinitely sized room room, but move them so far away that they're *very* faint (inverse square law), and they'll also appear as a washed out grey colour. That doesn't mean they're any less red, green, or blue, it just means our eyes have a hard time dealing with the colour of faint sources.

Cameras don't really have to deal with this same limitation - you can just expose for longer in order to collect more light.

>>
>>2817419
>Not him, but it seems you're just, in many words, agreeing with what he said

In some ways, perhaps, but in many ways, no. The problem is that a lot of what they said was overly simplified (with a few bits being flat-out wrong) or based on misunderstandings. Most of these points require a bit more clarification in order to ensure that people are properly informed about what he's *actually* talking about. For example, the "astronomical images are captured in black and white" stuff always raises a red flag to me, because it implies that the person doesn't understand how any digital colour photography works. The fact that these pretty colour astrophotographs are generated in fundamentally the same way as your cellphone camera's image usually comes as a surprise to most people.

I want to be careful in the distinction between "real" and "fake" when talking about these things. Like I said in >>2816823, the impression a lot of people get from these simplistic "the colours aren't real" statements is that the images are just arbitrarily painted over for (mostly) aesthetic purposes. I've seen quite a lot of people even take it further to suggest that these kinds of images are entirely artist renditions. Neither of these are true for these kinds of images. The colour data displayed in these images is absolutely real, it's just not on a 1:1 mapping with the filters in our eye's cone cells.

It doesn't help that the technical term "false colour" also implies "fake". (The technical term "true colour" has a similar but opposite issue.
>>
>>2817419
>Not him, but it seems you're just, in many words, agreeing with what he said

As for the "everything is a shade of white" stuff, the fact remains that most of these objects *do* have a strong inherent colour. It's merely an issue of observers bias - they're far enough away that they appear very faint, and our cone cells aren't as sensitive as our rod cells so they *appear* more monochromatic than they actually are. The same effect occurs to human vision at night - with less light, our vision becomes much more monochromatic. But you wouldn't then argue that the same pretty field of flowers is actually just "shades of white" because, through an observer bias, your colour vision is significantly reduced at night.

This is a cute point about astronomy that is fun to explain to school groups on tours. But the fact that it's "only" an observers bias is important to remember. And importantly, when you suggest that "everything is just a shade of grey", it further reinforces the above misconception about the "fake" colours in all these images. This is why I like to (try) to be clear about this sort of stuff.

These objects *aren't* just shades of grey. Most of the images of nebulae posted here have strong emission lines that peak all throughout the visible spectrum. Some of them (eg. M42) are bright enough that our eyes can start to see some colour through larger amateur scopes. But most importantly, we have developed instruments that we can expose for longer periods of time in order to capture an objective image of these objects under various wavebands. We don't need to rely on our limited, meatbag eyes for these kinds of things.

how can gas exist in space?

...the vacuum of space. although the temperature is low, the pressure is almost 0, and therefore the materials are in a gas state Mars average temperature is about -30C but water boils there in to vapor it's colder in space...I have come across conflicting information. I have read there is no matter at all in space, and also that most of the gas in space is hydrogen and helium.

image: Located about 6,000 light-years from Earth, the Heart and Soul nebulae form a vast star-forming complex that makes up part of the Perseus spiral arm of our Milky Way galaxy. The nebula to the right is the Heart, designated IC 1805 and named after its resemblance to a human heart. To the left is the Soul nebula, also known as the Embryo nebula, IC 1848 or W5. The Perseus arm lies further from the center of the Milky Way than the arm that contains our sun. The Heart and Soul nebulae stretch out nearly 580 light-years across, covering a small portion of the diameter of the Milky Way, which is roughly 100,000 light-years across.

Then this image was taken of the Stephan’s Quintet as part of the commissioning process by the Large Monolithic Imager (LMI) on Lowell Observatory... now that's better
>>
then some bright spark pointed Hubble at it...

Located in the constellation of Pegasus, Stephan’s Quintet is a group of four galaxies whose respective gravities lock them in a cosmic dance with each other that will inevitably lead to their coalescence. The fifth and brightest member of the group, NGC 7320, is in fact just 40 million light years away but viewed from Earth appears to be spatially associated with the aforementioned group and thus makes up the fifth member of the quintet. Unfortunately my 80 mm telescope only shows a smudge of light from Stephan’s Quintet but it is light that has just arrived here at Fairvale Observatory after making a 300 million year journey, it is literally looking back in time. A more substantial Hubble image shows us exactly what was happening to these galaxies at that moment – it seems probable that they have by now come together but we’ll have to wait another 300 million years to see that.

the nearby galaxy Centaurus A'
Cen A' is about 12 million light years away and has roughly the same mass as our Milky Way, containing a few hundred billion stars. The underlying glow of those stars is what makes that round background fuzz in the image, and takes on the familiar elliptical shape of many such galaxies...
Note: All the individual stars you see here are in our on galaxy, since we’re inside the Milky Way looking out to Cen A'. Also, the little circles next to bright stars are reflections inside the camera itself, and aren't real.

...when you observe Cen A' using a radio telescope it gets weirder... two huge jets of material are being shot out of the core. The image here shows those jets... Cen A' is a very strong emitter of radio waves... in fact that’s why it’s called Centaurus A' being the brightest radio source in the constellation of Centaurus.

>Your religious bullshit will never be as satisfying as scientific truth.
Like, for example, that black people have a low average IQ, and that virtually all scientific, cultural etc progress was due to white and Jewish people.
Hitler's eugenics, too, is merely science - the logical conclusion of Dawrinism. Who cares for a God that offers universal love, hope and dignity to all people, and who is the source of universal human rights? Human rights aren't science. Dignity is no science. Humans should be replaced with robots and AI, they are more efficient. Science! There is also no scientific argument against torture, colonialsm, or slavery.

Although it appears close to the centre of the Milky Way on the sky, it is relatively near to Earth, at a distance of about 5500 light-years. It is about 50 light-years across and is one of the most active star formation regions in our galaxy, containing massive, young brilliant blue stars, which have formed in the last few million years. It is host to possibly tens of thousands of stars in total

Stephan's Quintet is one of 100 other compact galaxy groups which was catalogued by Paul Hickson in 1982. So if you want to get an idea for what it might look like once some of those galaxies have properly collided, a good start would be to take a look at images of some of the other Hickson compact groups.

Pic related is Hickson Compact Group 31 (HCG31). Obviously the two (possibly three, hard to tell from an image alone!) galaxies are looking like a bit of a mess following collision. You can also see a stream of new hot blue stars through the middle of the image - it's really common to see bursts of star formation like this during galaxy collisions, as you get big collisions of gas/dust clouds within the galaxies, which compress and collapse into nice star forming regions.
