Explore the depths of the universe

NASA's three most advanced space telescopes prepare to join forces to explore the deepest parts of the universe, opening new frontiers before humanity.

According to Space.com, Hubble space telescopes, Spitzer and Chandra will see six giant galaxies in the next three years, according to a part of a project called "border schools ". Working together, the trio will be able to reach the early galaxies of the universe, ie several hundred million years from the Big Bang event. 'The Border Schools Program is the dream project of NASA astronomical observatories: joining forces to discover the mysteries of the universe' , according to John Grunsfeld, head of the scientific missions of the Agency. American aerospace.

Expert Grunsfeld said each observatory collected images by taking advantage of different wavelengths of light, helping researchers to better understand the physical foundations of celestial bodies in the distant universe. For example, the Hubble telescope observes visible, near-infrared and near-ultraviolet light wavelengths, while Spitzer is tasked with infrared imaging, while Chandra's powers are best exemplified in the light. shining X-rays. The project will take advantage of a phenomenon called 'gravitational lensing' , whereby the gravitational field of a giant object near it is bent and lights up the light coming from an object. farther, like the lens case.

In this case, six giant galaxies, starting with Abell 2744 (also known as Pandora's constellation), act as lenses, and the magnified objects will be faint, distant galaxies. sticky in the deep universe, some have never been observed before. 'The idea of ​​the program is to take advantage of the natural telescopes of the universe, combined with observatory space on the space to remove visual limitations, allowing astronomers to see the most distant and weak galaxies ', says Jennifer Lotz, principal investigator at the Space Telescope Science Institute in Baltimore. According to calculations, 'galaxies' lenses will boost Hubble's capacity to at least three times higher than today. Even in some cases, they can allow observing objects at distances 10 times the Hubble normal range.

Spitzer and Spitzer data will help scientists measure the distances and masses of these galaxies accurately. Meanwhile, Chandra's observations will support the calculation of the mass ratios of galactic constellations, the real power of gravitational lenses, as well as the detection of background galaxies, which contain black holes. at their center.'We want to find out when and how the first stars and galaxies were formed in the universe, and every observatory provided different pieces of the puzzle ', according to Peter Capak, home The main study of the Spitzer project of the California Institute of Technology in Pasadena.

It is known that the first 50-hour continuous observation period has been implemented on October 25. During this period, Hubble will make 70 circles around the orbit for 6 weeks. The goal is the Abell constellation 2744, which combines four small galaxies about 350 million years ago.
