1. Because they need to promote this project. More than half of the people I talk to doesn't even know what jwst is, and if they do, most of them couldn't even tell why would it be better than hubble or other telescopes

  2. Essentially, and this is very simplified, but a picture of a star is taken from ASTRONOMICALLY far away. Between the place the picture was taken and the star itself is something very large or very dense (an entire galaxy or a black hole, etc.) because of the sheer distance between us and the thing we're taking a picture of, the light traveling from the source to us is affected by gravity. this can have a few different effects, from a warbling look to a full Einstein Cross. Basically, it's SO FAR AWAY that the light of it has to pass through entire galaxies, which causes it to warble and move, making it appear larger or brighter than it otherwise would. It's kinda like a lens flare, but instead of being caused by a reflection, it's caused by light traveling through or near a very strong gravitational effect.

  3. putting it simply, light tends to propagate on straight lines, but if it pass through a gravity field strong enough it will bend, therefore the gravity field work like a lens

  4. For who will watch the video: the audio is really low. I had to up the volume to 100% to understand what they were talking even using headphones.

  5. Come on man they developed the picture of space with you know the thing. Thank our fellow ukramerican austromats for going up and taking this picture man

  6. Now look here, this thing can see so far in space man but I think we should use it to see what that little Russian guy putin is up to.

  7. You have a few interesting ideas here. Please know that a superposition of several eigenstates can be reduced to a single eigenstate due to interaction with the external world. This interaction is called an "observation" but it does not require a conscious "observer". There is probably a beach near you with many grains of sand, each one is making many such "observations" per second.

  8. Well said dude. I like to think of it in the inverse. Would you really want to live in a Universe so small and cramped and knowable that you were significant? Isn't it nice to know our fascinations will be endless?

  9. I like being insignificant in the scale of things. It's freeing to recognize you exist in a VERY narrow window in time in which we can look up at the stars and find answers our ancestors could old make legends to understand. We are so tiny and we live such fleeting lives. Even in the history of earth, humanity has existed but a blink of an eye, and yet in all these thousands of years of civilization, it is only within the last century that our understanding of space has become what it is, and in particular, the last few decades.

  10. Ignore the guy below you. Science has already proven reality only exists when observed. If consciousness ceased life as we know it ceases. This guy is bending your words to act like our will shapes reality. Your not saying we can bend reality to our will. Your simply relating scientific facts. Keep on keeping on brother.

  11. The notion that quantum interactions happen differently when they are "observed" by a consciousness is a common misconception, usually focused around the double-slit experiment and thought experiments like Schrodinger's cat.

  12. I wish the press conference had been just a slight bit more compelling with context and scale and photo quality. The director could have let one of the lead researchers give 2minutes of context, and limited himself to accolades and thanks.

  13. that sentiment of there being no greater meaning than the effect each individual can have on the world around them is pretty much the definition of nihilism. read Nietzsche. it’s a beautiful philosophy that gets a bad rap

  14. Thank you for this. For some reason I had comments sorted from New and this was at the top. I probably needed to read this after the overwhelming morning I spent after waking up to this picture and digging deeper on what it means. Thank you.

  15. The JWST is primarily an infrared telescope. The next big one to be launched in 2027 is the Nancy Grace Roman Space Telescope, which is supposedly the successor to the legendary Hubble Space Telescope. It's got a lens 100x bigger iirc so the pictures it would take should be just breathtaking. Exciting stuff!

  16. With it's perfect launch it might last as long as 20 years without being serviced. I have seen it mentioned that it is possible they will service it with a robotic refueling drone considering how hard it was to make that telescope.

  17. JWST has a mission length of 10cyears and fuel for 20, so as long as it doesn't suffer irreversible damage, itsgot a long life ahead of it.

  18. By this logic Nixon should never have made a speech about the moon landing. But it was proper for Nixon as POTUS to have done so, just like it was right for Biden to make the announcement yesterday.

  19. Thank god for people like you pointing out the hypocrisy, before you wrote that I actually thought Biden went to space with his Kodak and took them

  20. Don't insult the existence by saying that humanity is insignificant, nothing insignificant ever comes out of it.

  21. We give that big beautiful universe significance. We look up and are filled with wonder. Our only significance so far is that we can realize how freaking insignificant we are.

  22. Is it though? You can't say for sure. Relatively small in comparison to other celestial bodies, sure! But insignificant? Who knows. Maybe we find the answer to that in death... Maybe not.

  23. In the farthest galaxy, thousands of civilizations were born and died. Billions if not Trillians of lives have passed from when then light left their galaxy and arrived for us to see...

  24. Is it just me or is the volume incredibly low? I can hardly hear anything with the volume of my pc at 100% (normally I have it at 30%).

  25. Im guessing if the time axis of sight worked in reverse then it would be darker and having much less in the sky the further out you go, as the universe keeps cooling down and entropy keeps increasing. Theres also things getting spread apart due to the expansion of the universe, depending how far in the future you're talking about there might not be any galaxies visible.

  26. There are basically 3 different theories About how or why the universe will end. The big rip, big crunch and big Freeze.

  27. So actually our current "best guess" cosmology (lambda-CDM) predicts that the universe is expanding outwards and accelerating. But locally this effect is outdone, so solar systems and star clusters stay bound, but the distance between these objects is accelerating, so a future photo would be a lot less packed.

  28. Not an astronomer or physicist. Yes our universe is expanding. Last agreed upon fact is it's speeding up, though I hear more debate lately. Future generations may rise up under a dark sky. They may even come along after we merge with Andromeda and see nothing but our local stars. Believing we live in a galaxy in a void. Long after, all the medium plus stars will die out, and no new ones will form. Then, an unfahomably long time later, all the red dwarfs will die. This is call the heat death of the universe. All solar energy is dead at this point, and cannot restart. Then an even longer time than all time that has passed so far will pass. And all the nuclear bonds will be breaking down too. Meaning atoms can't form elements anymore.
