The James Webb Space Telescope is set to launch in 2018, and it has a lot of instruments. The Webb will be the world’s most powerful space-based telescope when it launches into Earth orbit. It will observe the Sun, planets, and their moons for the first time. NASA developed a total of five telescopes for the mission: The Near-Infrared (NIR), Spherical Aberration Corrector (SAC), Wide-Angle lenslet Camera (WALC), Adaptive Optics Wide Field Camera 3 (AOWFC3) , and Infrared Deep Space Camera (HIPCC). Each instrument on the James Webb Telescope was carefully chosen to give astronomers unique views of different parts of the sky. These three videos go over what each of those instruments can do.
What is a Spherical Aberration Corrector?
Spherical Aberration — also known as edge-on effect or diffraction — is an optical phenomenon in which the light from an object is bent slightly as it passes from one spherical surface to another. This shift in direction is what causes the term “spherical aberration” to describe this effect. Aberration affects all telescopes, but can be most significant in telescopes using long focal length optics — that is, those with a low dispersion design. Dispersion is the dispersion, or amount by which lightrays travel through a telescope. A low dispersion design is able to correct for spherical aberration by using a larger aperture (i.e., larger diameter) and a less Ach-y (or airflows) lens design. As an optical design improves, the lessening of spherical aberration leads to a brighter image. This is why telescopes with large apertures, like the Hubble, Spitzer, and Chandra, see a dramatic improvement in clarity over shorter periods of time.
What is a Wide-Angle Lenslet Camera?
Widescreen lenses are sometimes used on telescopes, and this can result in an optical design that is not very good at resolving close objects such as asteroids and comets. The problem is that the longer the focal length, the less light that reaches the sensor. To correct for this, telescopes with wide-angle lenses have an additional “wide-angle camera” that is mounted behind the main lens and imager. The wide-angle camera captures images at different apertures to “resolve” the light into its components. This process can produce great visual difference between the far-infrared light from a star and a deep-red nebula, for example.
What is an Adaptive Optics Wide Field Camera 3?
Wide field cameras are often found on the back of telescopes, but they can also be used as an imaging device, similar to a single-lens reflex camera. This is why many astronomers use wide-field cameras to “stitch” the light from multiple sources together to make an image — like the Hubble, Spitzer, and Chandra wide-field cameras. The wide field of view of these cameras give them a large field of view, but low resolution. The resolution of the images from the Wide-field Camera 3 on the James Webb Space Telescope is about one-quarter of the resolution of the cameras used on the Spitzer, and it will take about six months for the WFC3 to observe the same area as the Spitzer. Achieving this resolution, however, would require an extremely long lens. A wide-field camera has a field of view that is much smaller than an imaging camera, but it also has a large enough field of view to resolve objects in the visible spectrum.
What is the James Webb Space Telescope’s (JWST) Infrared Deep Space Camera 3?
This infrared camera is capable of picking up light from a range of angles and then reconstructing the light and displaying the image on a high-resolution HD screen. The JWST Infrared Deep Space Camera 3 is the result of a partnership between NASA and Madrid’s CCC (Cátedra Colgado Contreras) University. This latest infrared camera to be used on the JWST is expected to observe the same part of the sky as the earlier cameras — but in a much larger area. It will observe the entire sky three times a week for seven months, with a different region of the sky observed each day.
Conclusion
The James Webb Space Telescope will observe the entire sky three times a week for seven months, from its launch in 2018 until May 2020. It will be the most powerful telescope in the world when it launches. The JWST is a general-use telescope that can observe a wide range of topics in the skies. The JWST is a collaboration between NASA and the European Space Agency. It has five telescopes, two of which will be used for studies of the Sun and the planets. The mission is expected to last 5 years and cost $2.6 billion. The James Webb Space Telescope is set to launch in 2018, and it has a lot of instruments. The Webb will be the world’s most powerful space-based telescope when it launches into Earth orbit. It will observe the Sun, planets, and their moons for the first time.
