Astronomer Hubble used the Hook telescope to observe celestial objects

The phenomenon of cosmic background radiation was discovered in 1965 and the age of the Hubble telespace universe in 1998.

The observations of Cepheid variable stars by the Hubble Space Telescope provide a guarantee for the accurate measurement of the Hubble constant. Hubble's fine guide sensor provides a direct parallax measurement of Cepheid variables, which greatly reduces the uncertainty of estimating distances from Cepheids' perimeter-light relationships. Before the Hubble Space Telescope, the observed Hubble constant was 1-2 times different, but with the new Cepheid variable star observations, the uncertainty of the cosmic distance scale has dropped sharply to only about 10%, allowing for a more accurate understanding of the expansion rate and age of the universe.

Star formation. The Hubble Space Telescope is also useful for studying star-forming regions such as the Orion Nebula. Early observations of the Orion Nebula by the Hubble Space Telescope revealed that many young stars were clustered in disks of dense gas and dust.

Although the existence of these disks has been inferred theoretically and from observations of very large antenna arrays, it was not until the high-resolution images taken by Hubble that the structure and physical properties of these disks were directly revealed for the first time.

Stars die. Hubble's observations also established a link between supernova explosions and ray bursts. Through Hubble's observations of the afterglow of ray bursts, the researchers pinned these bursts to massive star-forming regions in extragalactic galaxies.

Thus, the Hubble telescope also convincingly demonstrated a direct link between these violent eruptions and the death of massive stars.

Black hole. One of the earliest core plans of the Hubble Space Telescope was to establish relationships between quasars and galaxies powered by black holes. Later, through their gravitational attraction on the surrounding stars, a kinetic model of the near-range galaxy spectra obtained for Hubble confirmed the existence of the black hole.

These studies have also led to reliable measurements of the mass of black holes in more than a dozen galaxies, revealing an extremely close connection between the mass of the black hole and the mass of the galaxy's nucleus.

Cosmology. Since cosmology is mainly based on astronomical observations, this is the only way to measure the distance and age of the universe based on the evolution and structure of the universe. The Hubble Space Telescope is able to determine the Hubble constant by measuring the distance of Cepheid variables, which is related to the rate at which the universe is expanding today.

In addition, the determination of supernovae can help researchers limit the brightness of supernovae, further limiting the properties of the early expansion of the universe, thus providing a powerful constraint for dark energy models. The mirror has detected galaxies 12 billion light-years away from the Earth.

Sorry, I couldn't find ten!

Yes: the discovery of Halley's Comet; discovery of extragalactic galaxies; establishing a theory of the expansion of the universe; Discovery of astral bodies.

Launched after 1990, he can see galaxies more than 10 billion light-years away. As one of the most successful astronomical telescopes in the world, the Hubble telescope has always been the well-deserved number one, although I don't want to say this, but we have to admit this problem, blindly avoiding this will not solve the problem at all, since the launch of the Hubble telescope, he has helped mankind observe many distances that we humans cannot touch.

As everyone knows, the universe is immeasurable, the earth has tens of billions of light-years away galaxies, for different reasons, so that human beings can truly appreciate the vastness of the universe, which is actually why human beings have always believed that in the universe, there must be a real reason for the existence of civilizations like the earth, even if the current stage is different, it is likely to be a hundred or a thousand times that of the earth, anyway, it should be more advanced than our human beings, and the danger of the universe is also immeasurable by our human beings. <>

At present, we do not have the Hubble Astronomical Telescope in China, our most advanced telescope in China, it is still under construction, it is called the 500-meter spherical radio telescope, it is based on the natural karst crater in Guizhou as the site, the pre-answer bridge town research lasted about 2013, he was carried out by the Chinese Academy of Sciences, sponsored by the Observatory, more than 100 scientific and technological backbones from more than 20 universities and research institutes across the country participated in this work. <>

In any scientific research, human thinking and technology are decisive factors, and the Hubble Space Telescope is no exception, the success of the Hubble Space Telescope is first of all due to the continuous efforts of several generations of astronomers, each of whom contributed different meanings and questions, in 1990, when the Hubble Space Telescope was launched, several scientists themselves witnessed this moment, for these scientists, it may be unforgettable in this life. <>

Today is July 29th, according to the latest news reports, the Hubble telescope detected a free latent black hole in space, which makes many astronomy enthusiasts excited by the silver state, and also makes many scientists have confidence in future research, this is a milestone scientific discovery, which is of high significance for promoting the study of the universe, which represents another step forward in our exploration of the universe, so, what is the practical significance of the achievements of the Hubble telescope in space?

Before the Hubble telescope detection, some scientists through precise calculations and reasoning, came to the conjecture that there is a free latent black hole in the universe, but because of the constraints of the current scientific and technological level of our earth, this conjecture can not be further verified, but this time the Hubble telescope detected the free latent black holeIt just proves that the free-latent black hole is real, and also confirms the conjecture of scientists from the side, which has a great role in promoting the exploration of the world's cosmological theoryIt has also given many scientists confidence in the future of cosmic research.

In recent years, the world's scientific and technological level has been widely improved, which is reflected in people's daily life, and this time the Hubble telescope can detect black holes, which is admired by many astronomy enthusiasts, which is an exciting good newsThe development of science and technology around the world has been reflected in the exploration of the unknown universe, which is a milestone scientific discovery, and in the future, science and technology will once again be stable and long-term developmentThe exploration of the universe is also a long-term path.

That's all for me, I hope it can help you.

The Hubble telescope is the most important telescope in astronomy, and the optical telescope launched above it in 1990, named after astronomer Edwin Hubble, is an optical telescope with a certain reputation. In 2019, scientists released the most complete and comprehensive atlas of the universe to date, which is spliced together from more than 7,000 starry skies** taken by Hubble over the years. After the launch of the Hubble telescope, the age of the universe measured was much more accurate than before the liftoff, and it also brought a lot of observation data, which provided a basis for the research results, and there were many bright spots in the course of 30 years.

1. Important results of the Hubble TelescopeThe goal of the initial launch of the Hubble Telescope was to measure the size and age of the universe, and there were some small results, and the data obtained was much more than that obtained by mankind before Hubble's liftoff. In the process of observation, the Hubble constant is a very important value, and after the observation and distance measurement of Cepheid variables, the measurement of the Hubble constant is worth a good improvement, and the error becomes smaller, and the effect is better. The launch of the Hubble telescope also confirmed the black hole conjecture, with a large amount of data proving that black holes, the centers of galaxies, are universal.

2. The Hubble telescope created conditions for human exploration of spaceThe Hubble telescope experienced a small episode when it first lifted off to achieve the expected effect, and the main reason was the spherical aberration of the main mirror, which solved this problem by installing an optical correction system for the Hubble telescope. Since then, the Hubble telescope has created a series of great achievements in the past 30 years, the Hubble telescope is a window for scientists to discover the mysteries of the universe, which is of great significance, it is no exaggeration to say that the Hubble telescope is the most important scientific instrument in modern astronomy, and the first article published according to its observation data is as many as tens of thousands. The Hubble Telescope has made a big laugh by providing humanity with a series of deep-sky galaxy maps from the deepest skies, as well as evidence of their existence and a beautiful starry sky map.

Now, after years of lift-off, the Hubble telescope is aging and is waiting for its successor to continue to make important contributions to space research.

The greatest significance of this achievement is that it can deepen the study of black holes and learn more about the universe.

Confirmed the predictions of previous scientists. It is also a big step forward for us human beings to explore the universe, and I believe that we will soon solve the mystery completely.

I think this achievement is of great significance, through the Hubble telescope, we can see free floating black holes, which means that black holes can float, and these black holes have no specific purpose, this type of number also brings more reference value to our future research history and research on black holes.

I think this has a very positive significance for us to understand the struggle, this ** can allow us to see the situation inside the black hole more intuitively, and also let us have different ideas about the internal power of the black hole and the organization and development of the black hole, and it will also help me to understand the black hole and the universe better.

<>It's this, the official doesn't admit that ** was taken by the Hubble Luhuai Space Telescope. Zhenla.

The state-of-the-art telescope made by Herschel was done with the assistance of ten assistants. It was a giant telescope, and it took Herschel four years to complete the 40-foot-long, 48-inch Birosail telescope. Take advantage of advanced astronomical telescopes.

He found the calendar to be like Saturn.

of two satellites. But this large telescope is distorted because it is too heavy. Herschel at the Cape of Good Hope, South Africa.

An observatory was established. His son, John Herschel, also became a famous astronomer, and the father and son co-founded the Royal Astronomical Society, of which he became its first president. On August 25, 1822, Herschel died.

This self-taught astronomer was the greatest astronomer of the 18th century.

He discovered the existence of extragalaxies in the Milky Way and the expansion of the universe.

From 1923 to 1924 at the Wilson Observatory, Hubble discovered 12 Cepheid variable stars of the Andromeda Nebula, and deduced that they were located outside the Milky Way and were the same star system as the Milky Way according to the circumferential light relationship, which made Hubble the founder of galactic astronomy.

In 1926, Hubble proposed a morphological classification of extragalactic galaxies, called the "Hubble classification", which is still used today.

In 1929, based on Shreifer's discovery of the phenomenon of redshift in spectral lines, Hubble combined his own observations and proposed that the farther away galaxies are, the greater the redshift, that is, the farther galaxies are speeding away, which is called "Hubble's law".
