NASA Launces Time Machine


The James Webb Space Telescope, also commonly called Webb, is the most significant advancement in human endeavor toward unraveling the mystery of the cosmos. This infrared observatory started in space with the support of NASA, ESA, and CSA; it can give a new perception of the evolution of the cosmos in the tendency to provide a glimpse of the Big Bang and its effect.

Webb is more than just a telescope – it is humanity’s most potent eye in the sky – providing the ability to observe the universe billions of years back and, hopefully, unlock the key to the cosmos’ evolution and provide answers to some of the most fundamental questions asked by humanity.

A mirror like no other: how Webb’s unprecedented design changes our understanding of the cosmos
Webb’s instrument, called the Mid-Infrared Instrument or MIRI, is designed to collect energy even from behind dust clouds and reveal the objects behind them. It has a mirror that is almost three times the size of the first space telescope, the Hubble, and is made of 18 hexagonal segments, collecting much more light than the earlier telescope, hence capturing the faint lights from the young universe.               READ MORE...

Galaxies in the Universe

The Milky Way is just a speck in a universe filled with an untold number of galaxies. But if we had to take an educated guess, how many galaxies are in the universe?


That sounds like a simple question, but it's anything but. The first problem is that even with our most powerful telescopes, we can see only a tiny fraction of the universe.


"The observable universe is only that part of the universe from which the light has had time to reach us," astrophysicist Kai Noeske, now outreach officer at the European Space Agency, told Live Science.
