NASAs $10 Billion Time Machine Launching Into Space! James Webb Space Telescope Ready

You will sure like this informative educational video. The famous James Webb Space Telescope is a space telescope being jointly developed by NASA, the European Space Agency, and the Canadian Space Agency. It is certainly planned to succeed the Hubble Space Telescope as NASA's flagship important astrophysics mission.

This is definitely one of the most exciting things to happen in cosmology. The James Webb Space Telescope is ready to be launched (almost ready)! It’s a $10 billion-dollar high-tech wonder that will explore strange new worlds, and search for life in our galaxy and beyond. It will see more stars than previous telescopes. We might be on the edge of finding the answer to the biggest question in science: Are we alone in the universe (the only planet with life)? 

See how this ‘First Light Machine’ will change the way we see the universe, and show humanity things it’s never seen before!

The James Webb telescope will be able to see far. According to NASA, Webb's resolution would allow it to see the details of an object the small size of a USA penny 24 miles (40 km) away.

Where is really the James Webb Space Telescope now? Kourou. After nearly 2 decades of development, and around 7 launch delays, the space observatory is now fully fuelled and sitting in the final assembly building in Kourou, French Guiana, ahead of blastoff (scheduled for no earlier than December 24).

Webb is about 100 times stronger than Hubble and will look back to around 200 million years ago when the universe's so-called oldest stars and galaxies started to form.

The James Webb telescope will take some time to "unfold." 12 days post-launch, the telescope's primary mirror will begin to unfold. After that, it will take a further 10 days to move all 18 mirror segments into their correct positions, and Webb's operators on Earth will spend the next few months fine-tuning their alignment.

The James Webb telescope will see many things. The James Webb telescope is expected to identify galaxies that may have formed when the universe was 100 million years old. It's strong enough to see through things like dust clouds and a distance that the Hubble telescope is not capable of reaching.

There is an oldest thing we can observe in the universe. With a so-called redshift of z = 8.2, at the time of observation, the burst was the most distant known object of any kind with a spectroscopic redshift. GRB 090423 was also the oldest known object in the Universe, apart from the methuselah star. As the light from the burst took approximately 13 billion years to reach planet Earth.

HD 140283 (or the Methuselah star) is a metal-poor subgiant star about 200 light years away from the planet Earth in the constellation Libra, near the boundary with Ophiuchus in the Milky Way Galaxy. Its apparent magnitude is 7.205. It is one of the oldest stars known. The star's light is somewhat blueshifted as it is moving toward rather than away from the Earth and it has been known to astronomers for over a century as a high-velocity star based on its other vectors (proper motion). An early spectroscopic analysis by Joseph W. Chamberlain and Lawrence Aller revealed it to have a substantially lower metal content than the Sun. So-called modern spectroscopic analyses find an iron content about a factor of 250 lower than that of the Sun. It is certainly one of the closest metal-poor (Population II) stars to Earth. This interesting star was already known by 1912 when W. S. Adams measured its astrometry using a spectrograph in the Mount Wilson Observatory.

The James Webb telescope was certainly "delayed" many times. A faulty data cable between the James Webb Space Telescope and launch pad equipment at Europe's Spaceport in Kourou, French Guiana, caused the big observatory's latest launch delay, European Space Agency (ESA) and NASA representatives said in a briefing on Thursday (Dec. 16).

The James Webb telescope was expensive to create. Sitting in an important spaceport in French Guiana, it is extraordinary technology. At $10 billion, it is the most expensive telescope ever to be launched into space: the James Webb Space Telescope.

What time does the Webb telescope launch? 7:20 a.m. EST

NASA's James Webb Space Telescope officially set to launch Dec. 24. Liftoff is at 7:20 a.m. EST (1220 GMT).

Stars are seen "back in time". It takes light the speed of light to travel to earth to be seen. Webb is the $10bn (£7.6bn) successor to the Hubble Space Telescope. The new observatory has been designed to look deeper into the Universe than its predecessor and, as a consequence, detect certain events occurring further back in time - more than 13.5 billion years ago.

Webb technology will observe primarily in the infrared and will have four science instruments to capture images and spectra of astronomical objects. These instruments will provide wavelength coverage from 0.6 to 28 micrometers (or "microns"; 1 micron is 1.0 x 10-6 meters).

Webb will use so-called infrared light, which cannot be perceived by the human eye, to study every phase in cosmic history. The telescope's four scientific instruments are specifically designed to capture infrared light, and will be able to peer through cosmic dust to study colder or very far-away distant objects.

Infrared (also sometimes called infrared light) is electromagnetic radiation with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter to the nominal red edge of the visible spectrum, around 700 nanometers.

The mirrors of the "JWST" have a thin gold layer. After the beryllium mirror segments were polished a thin coating of gold was applied to it. Gold helps improve the mirror's reflection of infrared light. The gold was coated using a so-called technique called vacuum vapour deposition.

Webb will have detectors. Webb will have 2 types of detector arrays (SCA): visible to near-infrared arrays with 2,048 x 2,048 pixels, and mid-infrared arrays with about 1,024 x 1,024 pixels. Several detectors will be built into mosaics to give a larger certain field of view.

There is a telescope that exists to see black holes. The Event Horizon Telescope is a global network of synchronized radio observatories that work in unison to observe radio sources associated with so-called black holes with angular resolution comparable to their event horizons.

The NASA's James Webb launch is a so-called "Make-or-Break" moment for astronomers. On Dec. 24, after 20 years of engineering, the multibillion-dollar telescope is scheduled to lift off. It will look far into the universe. Hopefully it will not explode. Hopefully it will not become broken.

20 years ago, a crew of aerospace engineers started constructing Webb as a hyper-complex way to get past so-called "mere-mortal" restrictions of what can be seen in outer space.

2 decades, more than $10 billion cost, various delays and brilliant work later, the largest and most powerful telescope ever built by NASA is finally coming closer to its launch date.

Completely new innovations were done, such as "bonding single crystal optics that would survive at cryogenic temperatures."

By shooting so-called carbon dioxide snow at the surface, engineers are able to clean large telescope mirrors without scratching them.

Webb's important feature is the near-infrared camera, or NIRCam.

The predecessor to James Webb (NASA's Hubble telescope) also has infrared imaging capabilities, but they are inferior.

At this time, the Webb is at the tip of an Ariane 5 rocket in French Guiana, and folded up.

Once it enters outer space, it will cool down to its freezing temperature and unfold its 18 mirrors. The mirrors also will be aligned. They all have to act like one mirror.

Compared to the Hubble , the Webb is certainly bigger and more advanced.

In many ways, it is the most powerful telescope ever constructed.

This is an international collaboration between NASA, the European Space Agency and the Canadian Space Agency.

2 key Canadian components that are part of an estimated CAD $200 million contribution include a guidance system and scientific instrument for examining the atmosphere of faraway planets.

The Webb telescope will travel about 1.5 million kilometres away (beyond the moon). Astronauts will not be able to come with repairs. There’s always the possibility it could explode, as well.
