Hubble interstellar mining
I love good boy 2003)
synopsis - Synopsis:
the 12-year-old boy Owen (Liam Aiken) walks his dog for his neighbor all summer long. His work has finally paid off. His parents adopt a dog as a pet for him. Owen and the dog "Hubble" get along well and soon become best friends. One out of the ordinary Erwin as like as two peas in the sky, one day, he discovered that his "Harbert" was different. It was actually an interstellar investigator from "dog star". In the distant and far away Sirius galaxy, there was a planet called "dog star", where civilization was highly prosperous, and the wisdom and wisdom of it were as good as those of dogs on earth. Ah, no, no, it should be said, because they had been planning to invade the earth thousands of years ago to colonize the earth, so they sent a lot of spies to the earth to collect intelligence, so there were dogs on the earth. However, thousands of years later, no spy has ever sent back any information. It seems that they have been "evaporated" for no reason. So dogstar sent their best investigators to earth to investigate what happened. Of course, this investigator is Hubble. After getting along with young Owen, Hubble finally understood why all the dog star spies were gone without any news. They would never want to help their hometown invade the earth again. Now, Owen and Hubble's most urgent task is to train the disorganized dogs next door, because Hubble's boss, Da Dan, is going to visit the earth. If she can't see the well-organized troops from dogstar, all the dogs on the earth will be recalled to dogstar for retraining. In that case, human beings will lose their most loyal friends forever...
Since the Hubble telescope was released into the outer space of the earth's atmosphere by the space shuttle Discovery in 1990, it has made a lot of contributions to mankind, and it has taken tens of millions of pictures. Due to the design error in the early stage, Hubble suffered from myopia, poor focusing and poor image definition. Later (1996) after repair, the function was greatly improved, and the image definition was also improved. The restored "Hubble" took a clear picture of quasars in the deep dome of the universe some time ago, and also took a picture of the invisible life body at the edge of the solar system - the gaseous life body in the shape of human beings, which is a great credit. Because this kind of photos can be used as evidence of the existence of high energy and high intelligence invisible life in the universe in E.T. research
Recently, the Hubble telescope has made new achievements. It has discovered the existence of super black holes and new bright new stars. This brings new good news to astronomy In February 1997, two astronauts on the U.S. space shuttle Discovery went on a spacewalk and added 11 new equipment with a total value of US $300 million, including near-infrared photography, multi-target spectrometer and Space Telescope image spectrograph, to the Hubble Space Telescope. These new devices played a crucial role in the new discovery announced on the 12thfor example, the newly installed near-infrared camera and multi-target spectrometer are superior to other telescopes that observe through visible light e to the observation through infrared light. It can penetrate interstellar st and "see" the famous Orion Nebula. In this nebula, a large number of new stars are being bred. Near infrared photography and multi-target spectrometer images of the Orion Nebula show that countless gorgeous and strange shapes of material ejected from some of the giant stars "new life" in the process of formation
the scientists also observed another Nebula 3000 light-years away from the earth through near-infrared photography and multi-target spectrometer. In that nebula, there is a "dying" star, constantly erupting gas and st. Roger Thompson, the scientist in charge of the installation of near infrared photography and multi-target spectrometer, said: "through the images taken by Hubble, we can understand a series of scenes of stars from birth to death."
Another new device, the Space Telescope image spectrograph, has also made great achievements, finding a large black hole in Virgo that is at least 300 million times the mass of the sun. Because black holes suck in everything around them, including the light itself, we usually can't take pictures of the black hole itself. However, by analyzing the different materials represented by different parts of the spectrum, the Space Telescope image spectrograph shows the Z-type spectral curve of the material rotating around the black hole at a very fast speed, which is an important evidence of the existence of black holes. Since the space shuttle discovery was released into space in 1990, more than half of Hubble's 15 year design life has passed. However, the repaired and updated "Hubble" is opening up the mysterious veil of the universe with more excellent functions! In the future, according to the plan, Hubble will bring more Gospel and surprise to mankind by regularly updating its functions In addition, American scientists are currently developing new space telescopes with higher performance to further reveal the mystery of the universeOh, well, it's not a scam or a trap, but when it comes to operation, it's absolutely fast. Otherwise, the profit will not be very good.
Hubble also studied the spatial distribution of the spiral nebula. In 1936, he drew the spatial distribution map of the spiral nebula in galactic coordinates in his book Nebula world. The image shows that there are almost no vortex nebulae on the galactic plane, and there are not many on both sides of the galactic plane. With the increase of the Galactic latitude, more vortex nebulae can be seen. This phenomenon is e to the absorption of the dense interstellar matter near the Galactic galactic plane
he also studied the luminescent mechanism of galactic nebulae. In 1922, he pointed out that near the emission nebulae, there are always stars with spectral type earlier than type B1, and near the reflection nebulae, there are always stars with spectral type later than type B1< In 1953, Hubble died of a stroke on his way home. In 1990, NASA launched the world's largest astronomical telescope at that time to search for life in outer space. When it was named for the telescope, they thought of Hubble. To commemorate the great achievements of Hubble, the telescope was named "Hubble Space Telescope". This is the first of four space telescopes in NASA's grand Observatory program. The other three are: Compton gamma ray observatory, Chandra X-ray Observatory and Spitzer infrared space telescope. The Hubble Space Telescope is mainly used for optical and near-infrared observation. These four space telescopes cover the whole wave band of electromagnetic waves and make epoch-making contributions to human understanding of the vast universe
Hubble's works include Nebula world and exploring cosmological problems by means of observation, both of which are famous works of modern astronomy. He was awarded the Pacific Astronomical Society medal and the Royal Astronomical Society gold medal
The disappearance of a known exoplanet from view has led astronomers to speculate that it was not a planet from the beginning, but the remains of a ladder collision
“ This planet & quot; Erratic, elusive
“ A giant st cloud will be in such an orbit after it is exposed to the radiation force of the main star Norodom; Gá spá R explained & lt; Our model can explain all the observable factors in the system: its expansion and contraction rate, its graal darkening and its orbit& rdquo;
the debris field is now thinly scattered, extending to an astronomical length, that is, the average distance between the earth and the sun. In the future, astronomers plan to observe the system immediately after the launch of the James Webb Space Telescope. In addition to searching for real planets orbiting the star, scientists plan to analyze the salient features of the star system& mdash; Chemical composition of the wreck disc
400 years ago, 1609 years ago, the farthest universe we could see with the naked eye was the triangularis Galaxy about 3 million light-years away. A little closer are Andromeda, 2.5 million light-years away, and little Magellanic, 200000 light-years away. The farthest stars you can see are no more than 1000 light-years away
however, there are as many as 2 trillion galaxies outside of these visible galaxies. In 2013, the Planck Space Telescope observed the cosmic microwave background radiation, and the age of the universe was 13.798 billion years (about 13.8 billion years). Because the universe is expanding all the time, the universe that we can observe, if centered on the earth, extends outward within 46.5 billion light-years. The speed of light is about 300000 km / s, 46.5 billion light years, which means that light has traveled 46.5 billion years
for us, the distant space has always been mysterious, and revealing the secrets of the universe has become our eternal desire and motivation. How can a mere 3 million light-years satisfy our desire to explore the universe? We want to see a more distant universe
In 1608, Hans liebersch, an eyeglass merchant in Holland, accidentally discovered that two lenses together could see more distant objects, so he invented the telescope. This discovery, for those with keen perception, realized that it had a huge effect. One of these people was Galileo, who first invented the astronomical telescope by using lenses in 1609. At this time, we have been able to observe many scenes of the universe that can not be seen by the naked eye. For example, Galileo observed the moon of Jupiter through the astronomical telescope at that time. Later, Ole Romer also calculated the speed of light at 225000 km / s through some rules of the operation of the moon of Jupiter Since then, the sensitivity and resolution of the telescope have been continuously improved. In 1611, German astronomer Kepler improved the telescope and increased its magnification. Shaina's telescope, based on Kepler's design principles, also saw sunspots in the sun. In 1917, Huck invented the telescope, with which Hubble discovered the amazing fact that the universe is expanding...
because gravitational wave is a disturbance of space-time itself, unlike electromagnetic wave, it does not lose any energy in the process of propagation. No matter what the object is, it can't stop the gravitational wave. So gravitational waves have more advantages in exploring the universe. Scientists can use gravitational waves to understand black holes, dark matter, dark energy and even the mechanism of the birth of the universe
in the process of exploring the universe, from the naked eye to telescopes, to space telescopes, radio telescopes, to neutrinos, gravitational waves... Are the crystallization of human wisdom. To explore nature, we are not limited to our own conditions Kevin Kelly, author of what technology wants, said: technology is a power to make the world more and more orderly. The development of technology will be accompanied by the process of human civilization. The progress of technology will let us know more about the secrets of nature, so as to benefit human society. After gravitational waves, what else can we use to explore the universe
