James Webb Space Telescope

James Webb Space Telescope - Science Feed

In order to observe the universe, we need a telescope. But there is huge difference between a traditional telescope and a space telescope. A space telescope is able to observe things beyond imagination. In this article, we will explore about James Webb Space Telescope.

James Webb Space Telescope is largest telescope in space right now. It is built in collaboration of NASA (National Aeronautics and Space Administration), ESA (European Space Agency) and CSA (Canadian Space Agency). The purpose of James Webb Space Technology was to observe the formation of distant galaxies, exoplanets, discoveries related to formation of first stars etc. This telescope was launched on 25 December, 2021 where its destination was a solar orbit about 1.5 million kilometers from Earth.

This telescope is far different from our traditional telescope because it seeks out for near-infrared rays, orange and red light for observation. The telescope has 6.5 meter diameter gold coated beryllium primary mirror made of 18 separate hexagonal mirrors. It has gold coating for infrared reflectivity. There is an ISIM (Integrated Science Instrument Module) which provides power, cooling system, structural stability and computing resources to it.

Here is the list of important components in JWST:
NIRCam (Near Infrared Camera), NIRSpec (Near Infrared Spectrograph), MIRI (Mid-Infrared Instrument), FGS/NIRISS (Fine Guidance Sensor and Near Infrared Imager and Slitless Spectrograph)

On the software side, it uses Nombas ScriptEase 5.00e which is modification of Javascript for the on-board scripts. Also, the flight software is written in C++.

The development of JWST was started in 2000 but with name of Next Generation Space Telescope which got changed later. The goal was to make the better version of Hubble Space Telescope and Spitzer Space Telescope.

The first full color images of were revealed in 11 July, 2022 called Webb's First Deep Field.

There have been huge discoveries related distant objects that were thought to be non-existent. Very luminous galaxies were found estimated to be 235 to 280 million years after Big Bang. A large mosaic image of 690 individual frames of very early galaxies taken by JWST were released.

Quantum Computer at Google solves real world problem 13,000x faster than current Supercomputers - Science Feed

On 22 October 2025, Google announced that they have solved a real world problem using their Quantum Echoes algorithm that did the work 13,000 times faster than current supercomputers. This was the first time it has ever done where they used out of order time correlator OOTC algorithm. This algorithm is verifiable since it can be ran again and again to get consistent result. They have released a scientific paper over this where they were able to do study of molecular structure using their latest Willow quantum computing chip. This chip used 105 qubit arrays to simulate the molecular behaviour. In this task, they disturbed one qubit from the simulated structure which lead to the formation of butterfly effect inside kind of like wave. This was first done in forward operations. After this, they ran the same operation but from the reverse side. Both the sides waves start interacting with each other and give useful insights about the quantum nature. According to Google...

What is Kardashev Scale? - Science Feed

Have you ever imagined what is the sheer scale of our universe and how the future of human civilization is. There is scale of things that can be framed in and outside of our Universe. In this article, we have discussed the same curious question. Kardashev Scale is the method by which we measure scale of a civilization about their technological advancements, developments, scale etc. is based on the amount of the energy being used. This was proposed by a Soviet era astronomer Nikolai Kardashev in Byurakan Conference 1964 inside the article of Transmission of Information by Extraterrestrial Civilizations. Type I, II and III are the original types by Nikolai Kardashev. There are others types too since these three are not enough for complete explanation of civilization's scale. Type 0 Civilization This type of civilization is not able to harness and use energy levels of 4 × 10 12 watts/sec, basically less than that. In other words, the civilization must be able to use all...

Xenobots - The Living Bots - Science Feed

What are XenoBots? Xenobots or you can say human made living lifeforms are the type of robot which are made of living tissues and cells to work at microscopic level for different purposes like drug delivery to specific part of the body, collecting microplastics in the oceans and seas to make a large blob, etc. These synthetic robots are made of skin cells and heart muscle cells derived from stem cells which are took from frog embryos. Here, skin cells works as protection shield for heart cells where heart cells drive the xenobots moving mechanism. The structure of the bots are designed in computer simulation using evolutionary algorithms that uses trial and error method. Xenobots are capable enough to move inside living bodies and have life of weeks. These bots are also able to heal themselves. Xenobots are able to work in swarm to execute large task to move some specific material at microscopic levels. They have ability to self replicate new xenobots with sam...
