NASA’s iconic Hubble telescope hit the 1 billion second mark in space in January 2022.
The Hubble Space Telescope was deployed from the cargo hold of the space shuttle Discovery on April 25, 1990, at a distance of nearly 550km above the Earth’s surface.
On January 1, 2022, Hubble marked its billionth active second. During its lifetime, the telescope has produced many of the most iconic images. In addition to these cosmic images, Hubble has provided ground-breaking scientific discoveries, including determining the age of the universe to 13.8 billion years.
In its first billion seconds, Hubble saw 5 astronauts on missions to replace and repair parts of the telescope and have more than 1.5 million scientific observations.
“We can only imagine what discoveries will be made in the next billion seconds,” NASA wrote on the occasion of the milestone.
The Hubble telescope is expected to continue to operate for several more years, despite a recent incident that disrupted all or part of the observatory.
The future James Webb Space Telescope and Nancy Grace Roman Space Telescope will build on Hubble’s discoveries and work with Hubble to expand our understanding. about the universe”.
Hubble is a joint project of NASA and the European Space Agency (ESA), which was visited regularly by astronauts from 1993 to 2009.
These telescope observations have led to thousands of scientific articles, including new revelations about the origin of the universe. Other cosmic discoveries made possible by Hubble include the rate at which the universe is expanding, the discovery of the Fifth Moon around Pluto, and the discovery that supermassive black holes lie at the centers of most large galaxies.
The Hubble Telescope orbits Earth at about 27,300km/h in low Earth orbit, slightly higher than that of the International Space Station (ISS).
This telescope is named after the famous astronomer Edwin Hubble, who was born in Missouri, USA, in 1889. Recently, Hubble celebrated 31 years of operation in space with a photo of a giant star Giants are on the verge of destruction.
Hubble cost $4.7 billion to build and has a nearly 2.4m long mirror that can observe in the ultraviolet, visible and near-infrared fields.
The Hubble Space Telescope’s first observations of Jupiter were in March 1991, the planet the telescope regularly observes, including tracking Jupiter’s Great Red Spot swirling storm.
Hubble also provided the first convincing evidence for the existence of supermassive black holes at the centers of galaxies after observing the galaxy M87 in 1993.
Hubble’s main mirror has a width of 2.4m and a total length of 13.3m, equivalent to the length of a large bus.
Hubble is considered the most important telescope since it was first used by Galileo to observe Jupiter’s moon and is “a great loss” to astronomy if it stops working.
Affelia Wibisono, from the UCL Mullard Space Science Laboratory, said that Hubble was one of the most successful space missions ever launched.
“The Hubble telescope has revolutionized our understanding of the universe, from the discovery of new moons around Pluto, to capturing the first visual image of a planet orbiting a planet. the star is not the sun” – expert Wibisono said.
The Hubble telescope also helped astronomers create 3D maps of dark matter and discovered that every galaxy has a black hole at its center.
Boris Gaensicke, a professor at the University of Warwick, says that Hubble is one of the most important tools astronomers have ever used.
