The $10 billion gift to the world was that. A device that may demonstrate where we fit in the cosmos.
On Christmas Day of last year, the James Webb Space Telescope was officially launched into orbit. The planning, designing, and construction had lasted three decades.
Many questioned whether this instrument could live up to expectations as the illustrious Hubble Space Telescope's replacement.
We had to wait a few months for the enormous 6.5-meter primary mirror to be unpacked, focussed, and tested, as well as for the other components to be calibrated.
However, everything they had predicted was indeed true. In July, a celebration was staged by the American, European, and Canadian space agencies to unveil the first color photos. Some of the photographs that were subsequently released are what you see on this website.
Remember that James Webb is an infrared telescope first before anything else. It observes the sky at light wavelengths that are invisible to the human eye.
Its several cameras are used by astronomers to study various parts of the cosmos, including these enormous towers of gas and dust. Hubble frequently targeted the Pillars. If you were to go across this scene at the speed of light, it would take you several years.
This location is known as the Cosmic Cliffs. It's the edge of Carina, another dusty, star-forming nebula, which has a massive, gaseous cavity.
Strong UV radiation and winds from nearby hot, young stars have carved out the crater.
The distance between the two sides of this image is approximately 15 light years. 9.46 trillion kilometers is roughly how many light years there are (5.88 trillion miles).
The renowned Swiss astronomer Fritz Sticky made the discovery of the massive galaxy to the right in the 1940s. A direct collision with another galaxy gave it a complex cartwheel shape. Its diameter is around 145,000 light years.
James Webb examines more than just the deep Universe. It also explores solar system objects within our own. This gem is Neptune, the eighth planet from the Sun, as seen via its rings. The large "pointed star" above and the numerous little white spots that surround it are both moons. That is Triton, the biggest satellite of Neptune. A byproduct of how James Webb's mirror system was put together is the spikes.
One of the most well-known areas of the sky is Orion. It is a nebula that is 1,350 light years away from Earth and is a star-forming region. Here, Webb depicts the Orion Bar, a feature that is a wall of thick gas and dust.
In one of the biggest space stories of the year, NASA crashed a spacecraft into the asteroid Dimorphism to test the viability of diverting the 160-meter-wide rock's course. It was a trial run for a plan to protect the Earth from dangerous asteroids. James Webb saw the 1,000 tonnes of debris that the collision had thrown up.
The extravagant spiral arms of M74, sometimes known as the Phantom Galaxy, are well recognized. It lies the most face-on to us in the constellation Pisces, around 32 million light days from Earth, offering Webb the ideal view of those arms and their structure. The sensors on the telescope are especially consummate at detecting all the tiny threads of gas and dust.
