A lot of people don’t realize a new space race is upon us. China set the table, and NASA and co are trying to catch up (they might surpass, they might not! Time will tell)

yeah china is catching up pretty quick. their rocketry is still pretty rudimentary and based on western tech (and they still show no signs of rocket reuse), but they've been ticking some boxes lately like "space station" and "martian rover". their deep space exploration and novel satellite design is basically non-existent, but they do finally have a fully functional sat-nav system as of a year or two ago to rival GPS/GLONASS/Galileo. the west and the US especially still have a healthy lead but china has the ambition and funding to surpass them in the next 5-15 years if they try hard enough e: misinterpreted your post. it's china that is playing catchup from deep in the back here, not NASA lol. but they are working hard hot cocoa on the couch fucked around with this message at 17:52 on Sep 1, 2022 |

MrQwerty posted:there will never be a true picture of an exoplanet, it took flying a probe basically into Pluto to take pictures of it other than malformed dots well there is the idea of sending out a whole lot of little probes away from the target until they're at the perfect spot where our sun will gravitationally lens the light such that with enough probes you might be able to actually make out land masses

Seth Pecksniff posted:What gets me is that these stars look like they're literally next doo to each other, and yet they're most likely hundreds of light-years apart. No, those guys literally are next door to each other. The star cluster R136 you're looking at is only only about 50 light years across, and that central blob where they're so close that you can't resolve individual stars is like 6. It's a starburst area: a place where a whole shitton of thick gas condensed out into a whole lot of stars, many of them super-giants that are gonna burn out and go boom super fast. Here's the tl;dr of a big star forming nebula: 1. Somehow a lot of gas gets pulled together, either by gravity and movement inside the galaxy or interactions with other galaxies (the second is much more effective, and can make a whole galaxy light up with millions of new stars). At this point it looks like a big black blob. 2. The densest region starts collapsing under its own gravity, pulling in more gas. Little knots accumulate and get big enough to collapse down into proto-stars. 3. Dozens or hundreds of stars turn on, basically all at once in astronomical time. The first thing they do is turn all that cold dense gas around them into hot expanding gas. This shuts down star formation as gas gets dispersed from the cold dense blobs. This famous picture looks like dirt being blown away in strong wind, because that's exactly what's happening. 4. If this was a big cloud, a good number of these new stars will be giant fuckers that are so bright that they light up the whole cloud complex for 100s of light years around them. This takes a couple forms (reflection where light bounces off the clouds, emission where UV and Xrays from super-giants are absorbed by gas and then that energy re-emitted as visible or IR light). <--- All the pretty pictures of cool nebula are from this step 5. The energy and solar wind from the star cluster, and the biggest stars quickly going supernova, blows away all the gas and dust. The nebula fades out. Many of the stars spread out, but a tight cluster of them may hang together a long time and still be a recognizable group for millions or billions of years. Only 10% of the gas made it into stars, the rest eventually get scooped into new clouds in the long long future.

Webb can see into the interior of these dust clouds much better than Hubble. These "pillars" don't look nearly so solid anymore, huh?
