Gorgeous HD Footage Shows Humanity's Final View of The James Webb Space Telescope
We can all breathe a bit easier now. In spite of a launch bedeviled by problem after problem, NASA's James Webb Space Telescope is finally in space, making its way to its new home.

And if you needed a little reassurance that this is the case (which is totally understandable), the European Space Agency has released footage from the Ariane 5 rocket, which filmed the telescope in glorious HD as it zoomed away.In the three-minute real-time video, you can watch as Webb separates from the rocket, moving away, the solar array deploying after 69 seconds.It would be like trying to look at the skies through clouds—it just wouldn’t work.It's headed for a location some 1.Its five layers, each a plastic sheet as thin as a human hair and coated with reflective metal, together provide protection of more than SPF 1 million.5 million kilometers (just under 1 million miles) from Earth, in a region called a Lagrange point.(Of course, with every solution comes more challenges.Here, the combined gravitational forces of two larger bodies (in this case Earth and the Sun) create a small area of gravitational stability.“Primordial black holes are one possible form of dark matter.
Webb will sit in the second Lagrange point – there are five in total – on the far side of Earth from the Sun, also known as L2.) Why Does the JWST Look at Infrared Light? The JWST actually looks at two ranges of infrared light: the near infrared and mid-infrared.“Unfolding Webb’s sunshield in space is an incredible milestone, crucial to the success of the mission,” Gregory L.Not only will Webb be able to protect itself from the heat of the Sun, Earth, and Moon using its state-of-the-art sunshield , but it will also require the least amount of fuel, allowing its mission a much longer timeframe than other locations might.That heat protection is crucial, by the way: The cryogenic temperatures at that distance will minimize the interference from heat sources that might mess with Webb's infrared measurements of the early Universe.It's the wavelength that your TV remote uses (if you can find it—it’s probably under the couch cushions).Because it's so much farther from Earth than Hubble, the Webb space telescope will need to operate with minimal human involvement.The team has accomplished an audacious feat with the complexity of this deployment—one of the boldest undertakings yet for Webb.Engineers on the ground can communicate with the spacecraft, but we won't be able to service it at all.It turns out that everything produces light.5 billion years ago, the James Webb Telescope could be the bridge between Hawking’s decades-old idea and dark matter.
That means that we need to be able to fix any issues that might arise remotely, so it was worth the extra months making sure everything was in perfect condition before launch.Ariane 5's parting footage will be the last time we clap eyes on Webb for some time, if we ever do again.The wavelength of light that an object emits depends on its temperature.” Webb, a $10 billion instrument, launched on December 25 from a European spaceport in French Guiana.It's possible that another spacecraft will be able to snap a passing glimpse or two, but you shouldn't bank on it.Webb isn't equipped with any self-monitoring cameras; it would have been.So, while you can’t see light emitted in the mid-infrared range, sometimes you can feel it.
Are they blowing it up?
The Physics of the James Webb Space TelescopeHumanity has a new eye in the sky, with infrared sensors that will peer into the farthest reaches of the cosmos. Here’s how it works. I think it should focus on a close planet and probable show the land area given these first superb photos of distant stars and clusters.
The James Webb Space Telescope has fully unfurled its complex, massive sunshieldAwe-inspiring science reporting, technology news, and DIY projects. Skunks to space robots, primates to climates. That's Popular Science, 145 years strong. Good To Hear! Wouldn’t it be ironic if someone’s long hair was sitting on the lens….lol
The James Webb telescope could help solve the mystery of dark matterObservations by NASA’s recently launched James Webb Space Telescope could hint that many black holes formed during the birth of the universe. As soon as you actually find some let us know. Other than Black Holes that we all know about. Imagine it does Dark Matter (and Dark Energy)
COVID evolution and the Webb telescope — the week in infographicsNature highlights three key infographics from the week in science and research. Humans are the Virus Bowl where virus strains battle it out for dominance.
This amazing HD video is the last view we'll ever have of the James Webb Space TelescopeThe newly released HD video shows the observatory flying away from its rocket toward deep space. What part of Earth can we see there? If only we had another space telescope to view it with... Anyone know what region we see on earth?
