After more than 6 months in space, the NASAThis Tuesday (12) the US space agency will release the first scientific images captured by the James Webb Space Telescope, which will complement Hubble’s famous work.
Looking forward to this event g 1 I put together a 3D model of a very powerful tool Who will be able to observe the origin of the universe (See art above).
10 billion dollar observatory It was launched in December last year and now orbits the sun 1.5 million kilometers from Earth – It can explore where a telescope hasn’t gone before thanks to its huge main mirror and infrared equipmentwhich allows you to see dust and gases.
The first fully formed images will be published on July 12, but last Wednesday NASA provided an image of an engineering test, which resulted in 72 exposures over a 32-hour period, which shows a group of distant stars and galaxies. (See image below).
NASA said in a statement that the image appears a bit crude, but “Among the deepest images of the universe ever captured.” It offers an “irresistible glimpse” of what will be revealed in the coming weeks, months and years.

“When I took the picture, I was excited to clearly see all the detailed structures in these distant galaxies,” said Neil Rowlands, a telescope sensor program scientist at Honeywell Aerospace.
“The most fuzzy spots in this image are exactly the types of distant galaxies that Webb will study in his first year of scientific operations,” said Jane Rigby, Webb operations scientist at NASA’s Goddard Space Flight Center.
Bill Nelson, NASA Administrator, It was announced last week that James Webb is able to survey the universe farther than any other telescope.
“It will explore objects from the solar system and the atmospheres of exoplanets orbiting other stars, and reveal how similar these envelopes are to ours,” Nelson explained.

“It could answer some of the questions we have: Where did we come from? What’s there? Who are we? And of course, it’ll answer some questions we don’t even know what they are.”
Infrared capabilities of James Webb It allows you to see the Big Bang that happened 13 billion years ago.
As the universe expands, the light from the first stars differs from the ultraviolet and visible wavelengths emitted by the infrared, which Webb can detect with unprecedented accuracy.
Currently, the oldest cosmic observations date back to 330 million years after the Big Bang, but with the capabilities of the telescope, astronomers believe it will easily break the record.
