Exploring A Second Earth : NASA put the images taken by James Webb Telescope in public domain. These are truly mesmerizing, unprecedented photos, which tell us interesting things about the universe. One of these photos gives us the oldest glimpse of the universe. We can see 13.1 billion years into the past.
In another, we discovered an alien exoplanet where water, or H2O, has been found. Come, let’s try to understand these new discoveries.
Exploring A Second Earth Through James Webb Telescope
Friends, this telescope cost about $10 billion. It took NASA 25 years to work out its design and development. And most interestingly, the spot where this telescope is located currently, it is operating at the temperature of -266.75°C. It is so cold that it is almost at the absolute zero temperature of -273°C, temperature cannot fall beyond that. It is only a few degrees warmer than that.
To maintain this temperature, the James Webb Space Telescope doesn’t orbit around Earth, like the Hubble Space Telescope. Rather, it orbits around the Sun. About 1.5 million km from Earth, there’s a point known as the L2 Point, there’s it is always in the Earth’s shadow, in a way that it can safely orbit the Sun.
