After the release of the first breathtaking photos of “baby stars” last July, NASA’s powerful telescope, placed in orbit 1.5 million kilometers from our planet, returned the cover on the social network ) by broadcasting a photo representing the birth of a star.
”In this image, we see a newborn star with jets of supersonic gas spewing from its poles. This star is only a few tens of thousands of years old in this photo, but when it grows, it will look a lot like our Sun,” we read in the caption.
James Webb, more than a year of sumptuous images
In just over a year, the telescope has observed the most distant galaxies ever detected, supermassive black holes, measured for the first time the temperature of rocky planets “cousins” of the Earth, which it has even begun to analyze the atmosphere.
At the origin of a constant flow of scientific studies, the observations of James Webb – whose main missions are the exploration of the very young universe, the study of exoplanets, that is to say planets outside of the solar system, and the understanding of the formation and life cycle of stars – therefore never cease to challenge specialists.
In addition to these achievements, the general public was able to delight in sumptuous images. In October 2022, James Webb notably revealed his first photo of the emblematic “Pillars of Creation”, immense structures of gas and dust full of forming stars, 6,500 light years from Earth, in our Milky Way. .
10 breathtaking photos from a year with your head in the stars, thanks to the new James Webb telescope
The takeoff of this flying observatory worth $10 billion, aboard an Ariane 5 rocket at the end of 2021, crowned decades of work.
It is the successor to the Hubble space telescope, itself still in operation. Unlike Hubble, which observes the Universe mainly in the visible spectrum, James Webb works in the infrared. This allows it to detect much weaker glow, and therefore to see much further.
This wavelength being imperceptible to human eyes, the photos are then “translated” into visible colors.
James Webb has enough fuel to last 20 years.
