two amazing things that no one mentions: the flap on the back of the telescope is a small solar sail, its going to be used to help rotate the telescope to reduce the saturation of the gyros. another thing is that its so freaking cold on the shade side of the telescope, that you actually can use superconductors, and that is exactly what they did, some components are made of superconductors to reduce weight.

Yeah, it's not much but ANY form of thrust they can get saves fuel. The recent loss of the 40 Starlink satellites might be of interest to you, they use wires of some kind they deploy that interacts with the magnetic field along with thrusters to move the ship, leveraging the earths own magnetic field for orientation changes, it's damn near magical. They lost the satellites because the atmosphere swells when it's hit by a solar ejection/wind and their system would no longer work because of too much drag. The thrust they get out is pitiful, but it's 'free''

One thing I learned about that I thought was super cool was that we could also look for technosignatures. On top of the elements of biological processes, if there were a civilization on a distant planet, we could also potentially see silicon signatures like we do here on Earth which would be a much more definitive sign of advanced life or civilization on a planet, in concert with the appropriate biosignatures of course.

@Heistergand 2 жыл бұрын

Interesting thought. Imagine life in the universe developed everywhere in about the same time. Right now there would be millions of civs that are only a few thousand years more or less far developed as we are. What would be the time that the techno signatures needed to travel between two civs so that one 'sees' the other? If all civs survive, will there be an era of techno signature flooding in the far future?

@santyclause8034 2 жыл бұрын

Until we can somehow bridge a gap of millenia, I'm not overhype for finding intelligent life on a planet in a star system shining over 2k LY distant. Like, so what? What are we gonna do? The odds of a civilisation lasting and still remaining intact by the Time it took to reach it, I reckon, are slim. Then figure in the time it takes their EM telltale to reach our solar system, at Light speed its 2k years, so at minimum a span of 4k years from discovery to first contact give or take turnaround time (getting the journey craft put together etc). Plenty of time for Earth to forget, or its own civilisation to suffer a system collapse, or destroy itself, and all that negative stuff... We're talking a seriously longgg lead time here.

@@philipsmi-lenguyen8155 Fun fact, according to special relativity, variations in the two way speed of light doesnt break physics (since we have never measured the one way speed of light). This means that if it takes 20 minutes for a light to reach Mars and back... We have no idea if it took 19.9 minutes to get there, and only 0.1 minute to get back..... or if it takes 5 minute to get there, and 15 minutes to travel back... for all we know it could take the entire 20 minutes to get to Mars, and is instaneously relayed back to us. Einstein states that it is just easier for us to comprehend that light travels the same speed in both directions (although physics doesnt break if it doesnt, and we currently have no way of knowing how fast light actually travels in once direction)

Several years further on, *The Hubble Deep Field Image* was developed (from a composite of 342 images) & I was utterly blown away with the huge number of entire *Galaxies* seen in such an infinitesimally small section of the sky _(2.4 arcminutes a side / 24-millionth of the whole sky / or the area of a freakin' tennis ball @ 100 meters away!)_ - implying a truly staggering quantity of *Galaxies* in *The Known Universe.* Now, decades later, I get to see the amazing things that the *James Webb Infrared Telescope* will show of the early days of *Stellarsynthesis,* potentially habitable worlds & even *Infrared* views of the center of *The Milky Way,* without the obscuring dust blocking it - perhaps even high-resolution images of *Sagitarius A**

True, to some extent, but two things that have to be considered: 1. It is only at the longer wavelengths that it sees that its resolving power is similar to Hubble. At the shorter wavelengths it still has much greater resolving power than Hubble since the shortest wavelength JWST sees is less than double that of hubble. 2. The normalization is only applicable to the resolving power. When it comes to its light gathering capability there is no normalisation to be done.

I've just started watching your videos and I'm very, very impressed. Your ability to make the incredibly complex at least somewhat understandable is unparalleled. Can you please do a video on dark matter and dark energy? I am very curious as to why our universe continues to expand faster and faster and I think the scientific explanation is related to forces and matter we cannot see or detect. Initially I thought our universe continued to pick up speed because the absence of space and time outside the universe acts sort of like a vacuum to space and time, and the universe is rushing outward to fill the void, not unlike how air rushes to fill a vacuum. Apparently this notion of mine is way off, but no one has been able to explain it in a way that I can grasp. Maybe you will be able to help those of us who struggle to understand this mystery. Thank you!

@Physics Girl I like this video the best of yours (not that I've seen them all) -- the science details, the pleasure of you seeing your editor "get it"... E.g., I appreciate the dominant absorption wavelengths of water/carbon dioxide/methane, and what eras of EM radiation can be seen by HST vs. JWST vs. COBE/WMAP. So nice to have such a video showing two women involved in science posted on the International Day of Women and Girls in Science ! Hoping your head/eye heal completely and soon!

Kapton is seriously awesome.....We use Kapton tape at work and my Engineer asked today how can we isolate the GND vias from a RC filter mod we want to make...I said Kapton. He was worried about the heat from the solder iron, I took a piece of tape stuck it to wood and melted solder on the tape. The wood started burning but the tape was fine....He was so amazed and didn't know Kapton can do this. I then told him about JWST using Kapton as a heat shield. Kapton is awesome

1) Glad your eye is okay 2) As a photographer, everything having to do with our perception of wavelengths fascinates me 3) I have an old digital SLR that I converted to IR. The sensors of a lot of older cameras were originally designed for astronomy, and still have extended IR capabilities. They put what are known as "hot mirror" filters in front of the sensors to stop the IR from messing up your image. By removing the filter from the sensor, and putting a IR filter in front of the lens, you get IR pictures. Its hard to grasp what the Webb telescope is about to see.

One thing I heard about the sensitivity of the JWST is this: Imagine looking at a standard kids night light on the moon with one eye but divide that light by 20. Your one eye would see about 1 million photons of light per second from 1/20th of a night light at that range. JWST primary mirror being 6.5 meters (21 feet 4 inches) across will be focused onto and collecting approx. 1 photon per second.

@yasminesteinbauer8565 2 жыл бұрын

Webb & Hubble are very different instruments. And in fact, Hubble can do/see many things that Webb CAN'T do/see. They complement each other. But one isn't "better" than the other. They each do things better than the other, and they each do things that the other can't do.
