James Webb has the ability to send data bigger and farther.
REPUBLIKA.CO.ID, JAKARTA — The first collection of photos from the James Webb Space Telescope has just been released. These photos range from stunning galactic planes to minute descriptions of the atmospheres of distant exoplanets.
So how do dozens of terabytes of data travel from a spacecraft a million miles away to Earth?
This image is not a JPEG and Webb is not a camera. Webb collects and transmits reams of raw data from his instrument, two highly sensitive near and medium infrared sensors. Various accessories can specialize it for spectroscopy, coronography and other activities as needed, just like any other scientific equipment.
megapixel race
In 2008, the Hubble telescope, which is more similar to a conventional visible light telescope, captured an image of the Carina Nebula. The picture is a fantastic picture.
Hubble is more on par with conventional visible light telescopes and was launched in 1990. Since then, the technology has progressed quite a bit. However, the resulting photo telescopic head James Webb more detail.
Anyone looking at this small representation agrees that Webb’s version has a lot more information. The nebula’s thin texture expands into complex cloud shapes and clumps, revealing additional stars and possibly galaxies.
Hubble images have a resolution of about 23.5 megapixels and are 32 megabits without compression. Webb images are approximately 123-137 MB in size.
Although there is more than five times as much data, the picture is not fully revealed. According to Webb’s specifications, the instrument will send data back at a rate 25 times faster than Hubble, including larger and more images taken at a distance of 3,000 times greater.
