Us astronauts successfully retrofitted the Hubble space telescope

The Hubble Space Telescope (HST), named after Edwin Hubble, was successfully launched on April 24, 1990. It is an optical Telescope located above the earth’s atmosphere.In May 2019, Hubble Space Telescope scientists released the Hubble Heritage Field (HLF), the most complete and comprehensive map of the universe to date. The HLF is a Mosaic of 7,500 images of the sky taken by Hubble over 16 years. It contains about 265,000 galaxies, some of which are at least 13.3 billion years old.Studying it could help scientists gain insight into the history of the universe even further back.The Hubble Space Telescope, which has been observing the universe for more than 30 years, has been down for the past few days because one of its payload computers stopped working on June 13, NASA said On June 19, 2021, AFP reported.Hubble Telescope In the early morning of February 11, 1998, seven American astronauts aboard the discovery space shuttle blasted off to transform the Hubble space telescope after seven years in space.Since its launch in 1990, Hubble has traveled nearly 1.6 billion kilometers in space and made 110,000 astronomical observations for more than 2,000 scientists from more than 20 countries.Hubble has done a great job, but it is riddled with holes and needs to be repaired.In the early hours of February 13, US astronauts plucked the Hubble telescope from space and placed it on a platform in the space shuttle’s cargo bay.Astronauts carried out five spacewalks between late Friday night and early Sunday morning to repair 11 new pieces of equipment, including a near-infrared camera, a multi-object spectrometer and a space telescope image spectrograph, and repair some of the telescope’s peeling insulation.The Hubble telescope will be released into space in the early hours of February 19, with an improved “space eye” that will help us understand more about the universe.An American astronaut returned to earth in the early hours of February 21 after a successful overhaul of the Hubble space Telescope.The main achievements of the Hubble Space Telescope during its first seven years of service 1.it has improved our understanding of the size and age of the universe.2. Proving the existence of supermassive black holes at the centers of some galaxies and the possibility of black holes at the centers of most galaxies.3. The most in-depth study of the universe in the visible spectrum has observed thousands of galaxies and detected “primordial galaxies” in the early days of the universe’s birth, making it possible for astronomers to track the history of the universe’s development.4. It clearly shows the environment in which quasars, the brightest objects in the Galaxy, exist.5. The different processes of star formation are explained more clearly.6. The composition of heavy elements necessary for planets and life was studied during the formation of stars in the early days of the universe.7. Shows the complex composition of gas shells around dead stars.8. The detection of many dust disks around young stars in the Orion Nebula suggests that other planetary systems may have formed in our galaxy.9. Detailed observations of once-in-a-lifetime comet collisions.10. The climate and civil affairs of planets in the solar system such as Mars have been studied.11. The presence of oxygen in the atmospheres of Jupiter’s moons Europa and Ganymede.The Hubble Space Telescope has spotted a scalding “football” shaped exoplanet.The planet is so close to its star that it has been torn apart and heated, its atmosphere is speeding away and the whole planet is on the verge of being devoured.The planet is too close to its star to be torn apart by tidal forces.The “embrace of death” has twisted it into the shape of a football, with temperatures in the upper atmosphere exceeding 2,500 degrees Celsius.In January 2020, an international team of astronomers using the Hubble Space Telescope discovered the most distant and oldest group of galaxies known to date.The triple cluster is called EGS77.What’s more, the observations suggest that the triple cluster participated in a remodeling process called “reionization” in the early universe.EGS77 was born about 680 million years after the Big Bang, when the universe was less than 5 percent of its current age of 13.8 billion years.Attention – Jinyuan Education – learn not to get lost
