This light is called infrared radiation, and we can feel it as heat .
We can't see all the way back to the Big Bang itself or the immediate aftermath . 1.3 3.
Closest star system is about 4.35 light years so what you would see through a telescope is what that system looked like 4.35 years ago. Current telescope technology allows us to 'see' the Big Bang, in a way.
The most famous of these telescopes, COBE, was launched in 1989. The Cmb was emitted 380k years after the big bang.
And Neptune comes no closer to Earth than 2.67 billion miles (4.298 billion km), requiring a telescope of 11,000 miles (17,800 km) in diameter, or about 150% the size of Earth.
Since James Webb Space Telescope will look in the infrared, it can't actually see it. This happened at about 370,000 after the "Big Bang". . One of those images "is the deepest image of our universe that has ever been taken," said NASA. Webb is so powerful, it can detect the heat of a bumblebee as far away as the moon. Can A Telescope See Through Clouds Can A Telescope See Through Clouds Since the time when Galileo invented the first telescope in 1608, clouds have been a constant concern to amateur and professional astronomers alike and they have often wondered if a telescope can see through the clouds. The ambitious new device is designed to detect gravitational waves - an elusive phenomena created by some of the most violent events in the universe such as black holes, neutron stars and the Big Bang. There's really nothing to see, because light couldn't go anywhere before then.
1.7 7. Scientists will also use it to peer into the .

The $10 billion James Webb Space Observatory, NASA's largest and most powerful space research telescope, will investigate the cosmos to . Shifted Light. While the early galaxies are far off and on the way out of our particle horizon, we still have a long time to go (on a human scale) before we won't be able to see these objects "shortly" after the Big Bang.
Its mission is to search for the first light to ever shine in the universe.
And that is like opening a new window." The telescope could shed light on our origins as scientists believe that the elements emitted by dying stars created the sun, the planets .

We can still gather clues from before then using other tools. A telescope buried up to half a mile underground could give scientists their first glimpse of the dawn of the universe.
The telescope's ACS camera, the size of a phone booth, captured ancient photons of light that began traversing the universe even before Earth existed. If you think about it, we can use light to look at distant objects because light propagates freely from the matter which emitted it.
