Wave HD- Anne Hathaway shines on the red carpet in a high-definition dress. Judging from the close-up of high-definition pictures, what is her status?

High-definition photos, let's enjoy the "hot spot" where Jupiter vortex, the largest planet in the solar system, hits Jupiter's atmosphere.

In this series of images taken by NASA's Cassini spacecraft, a dark rectangular hot spot (top) interacts with a row of vortices approaching from the upper right corner (second column). This interaction will distort the shape of the hot spot (the third column) and make it smaller (the bottom). According to the scale, this black hot spot is about 6200 miles (10000 km) wide, about twice as wide as the United States.

These images arranged from top to bottom were taken by the imaging science subsystem of Cassini on June 5438+065438+1October 26th, June 5438+065438+1October 24th and June 5438+065438+1respectively.

Deep into Jupiter's atmosphere

The black "hot spot" in this pseudo-color image taken by NASA's Cassini spacecraft gives us a glimpse of Jupiter's atmosphere. It is surrounded by layers of high-level clouds, and the color indicates the part of the atmosphere where the clouds are located. The Yun Lan on the right is located in the upper troposphere or higher-the stratosphere. The red vortex at the lower right and the big red plume at the lower left of the "hot spot" are located in the lower troposphere. In addition, a high and thin layer of fog covered part of the picture.

The annotated version of this picture highlights the hot spots in the middle with arrows and boxes around plumes and eddies.

This photo was taken by the imaging science subsystem of Cassini in 65438+February 65438+March 2000.

Jupiter jet observed by Hubble

Along the path of Jupiter's jet stream, a row of V-shaped waves moves from west to east, just above Jupiter's Great Red Spot. On June 65438+February1kloc-0/0 and June 12, 2000, the Cassini spacecraft of NASA photographed the plane development of Jupiter. On the left, the waves met another storm called the South Equatorial Disturbance (SED).

Tiny ripples in Jupiter's rings.

Comet hits Jupiter

This artistic concept map shows that comet Shoemaker-Levy 9 entered Jupiter in July 1994, and its dust cloud formed a corrugated wake in Jupiter's ring.

The comet, photographed by NASA's Hubble Space Telescope, looks like a string of red debris falling into Jupiter from the south. One of Hubble's later photos shows the black spots formed by the collision of comet fragments with planets.

Dark rings in images obtained by NASA's Galileo mission are usually weak, but they are enhanced in this image. These stripes show the trajectory of the comet dust cloud. The impact of these dust particles made the ring deviate from its axis.

Cassini-Huygens mission is a cooperative project of NASA, ESA and ASI. The Jet Propulsion Laboratory (JPL) is a department of California Institute of Technology in Pasadena, which is responsible for managing the tasks of NASA's Scientific Mission Committee. The Cassini orbiter and its two airborne cameras were designed, developed and assembled in JPL (Jet Propulsion Laboratory). The imaging team is located at the Institute of Space Science in Boulder, Colorado.

Illustration: Comet Shoemaker-Levi 9 was photographed by Hubble Space Telescope on May 1994. It can be seen that Jupiter's gravity tore the comet into 2 1 block, with a diameter of about 5 kilometers.

30 of the most beautiful high-definition astronomical images show you the 30th anniversary of the Hubble telescope (Part Two)! By 2020, the Hubble Space Telescope will be in orbit for 30 years. The unique design of Hubble telescope enables astronauts to use advanced technology to maintain and upgrade it, making it one of the longest-lived and most valuable observatories of NASA, and has been sending wonderful astronomical images to the earth for decades.

Hubble fundamentally changed our understanding of the universe. On April 24th, 2020, in order to celebrate the 30th anniversary of Hubble, NASA released 30 wonderful images of Hubble telescope during its operation.

This image is similar to a rough sea wave, but it actually shows a foam ocean filled with hot hydrogen and a small amount of other elements (such as oxygen and sulfur). Hubble Space Telescope captured a small area in M 17, also known as Omega or Swan Nebula. Nebulae are hotbeds for the formation of stars. A large number of ultraviolet rays emitted by young massive stars on the upper left side of the photo carve and illuminate the wavy gas. The glow of these patterns highlights the three-dimensional structure of gas. Ultraviolet rays are carving and heating the surface of cold hydrogen clouds. The warm surface in this photo emits orange and red. Intense heat and pressure cause some substances to flow away from these surfaces, and even cover up the background structure, forming a hotter green gas luminous veil. The pressure on the wave tips may trigger the formation of new stars inside them. This photo was released to commemorate the 3rd anniversary of1Hubble launch on April 24th, 990.

This terrible object is like a nightmare beast looking up from the crimson sea. In fact, it is a pillar of non-toxic gas and dust. This huge pillar, called the Cone Nebula, or NGC2264, is located in the turbulent star-forming region. This photo shows 2.5 light years above the nebula, which is equivalent to 23 million times the height from the moon. The entire nebula is seven light years old. For millions of years, radiation from hot young stars (above) has gradually eroded the nebula. Ultraviolet rays heat the edges of dark clouds and release gas into relatively empty areas in the surrounding space. There, extra ultraviolet light makes hydrogen glow, creating a red halo around the column. Compared with the gas around a single star, the scale of similar process is much smaller, thus forming an arcuate arc seen near the upper left of the cone. The radian seen on the Hubble telescope before is 65 times the diameter of our solar system. Blue light and white light from surrounding stars are reflected by dust. You can see the background stars peeping at the tendrils in the evaporated gas, while the bottom of the turbulence is dotted with stars whose dust turns red. As time goes on, only the densest area in the cone will remain. In these areas, stars and planets may form.

The Horsehead Nebula rises from the sea of dust and gas like a huge seahorse, and it is one of the most photographed objects in the sky. Hubble Space Telescope's close observation of the sky reveals the complex structure of clouds. Horsehead nebula, also known as Barnard33, is a dark nebula composed of cold air and dust, which is in sharp contrast with the bright star cloud IC434. The bright area in the upper left corner is a young star, which is still embedded in air and dust. But the radiation from this hot star is eroding the star's nursery. Radiation from a giant star out of Hubble's field of vision is also carving the top of the nebula. By chance, the nebula is roughly similar to a horse's head. Its unusual shape was first discovered on the photographic film in A.D. 1800. The Horsehead Nebula, located in Orion, is the cousin of the column of dust and gas in the famous Eagle Nebula. Both tower nebulae are cocoons of young stars. This popular celestial target was the obvious winner among more than 5,000 Internet voters, who were asked to choose the astronomical target of the Hubble telescope 1 1 anniversary in 2000.

Hubble Space Telescope obtained this excellent image of planetary nebula NGC675 1. The nebula glows like a giant eye in Aquila. This is a gas cloud ejected from a hot star visible in the center a few years ago. When stars are near the end of their lives, they are gas shells thrown by mass stars, similar to the sun. The outer layer of the star is lost into space, exposing the hot star core, and then the intense ultraviolet radiation of the star core makes the ejected gas glow like a planetary nebula. The nebula shows several remarkable features: the blue region marks the hottest luminescent gas, which forms a roughly circular ring around the remnant of the central star; Orange and red indicate the location of the cooler gas. The origin of these Leng Yun in the nebula is still uncertain, but these streamers clearly prove the center of their shape influence; These stars are in a long streamer, in a tattered ring on the outer edge of the nebula. It is estimated that the surface temperature of this star is as high as 140000 degrees Celsius (250000 degrees Fahrenheit).

When the Hubble Space Telescope searched for volcanic plumes on the turbulent satellite Io, it captured this image of Io sweeping across Jupiter's huge surface and casting shadows below it. The smallest detail visible on Iowa and Jupiter is 93 miles (150 kilometers), or the size of Connecticut. The bright spot on Io is the area of sulfur dioxide frost. On Jupiter, white and brown areas distinguish high-altitude haze from clouds. The blue area indicates that the sky at high altitude is relatively clear. This is one of the three amazing images of the planetary duet released to commemorate the ninth anniversary of the Hubble launch on April 24, 1990. These images were taken at two wavelengths: 3400 A (ultraviolet) and 4 100 A (ultraviolet). These colors are not exactly the same as those seen by human eyes, because ultraviolet rays are invisible to human eyes.

Saturn is wrapped in bright colors to celebrate the eighth anniversary of Hubble's orbit. In fact, this false color image taken on June 4th, 1998+65438 shows the infrared light reflected by the planet. Infrared images provide detailed information about clouds and smoke in Saturn's atmosphere.

Blue represents the clear atmosphere under the main clouds. Different shades of blue indicate changes in cloud particles, size or chemical composition. It is considered that cloud particles are ammonia ice crystals. Most of the northern hemisphere visible above the halo is relatively clear. The dark area around the bottom south pole indicates that there is a big hole in the main cloud.

Green and yellow indicate that there is mist above the main clouds. When the color is green, the haze is thin, and when the color is yellow, the haze is thick. Most of the southern hemisphere (the lower part of Saturn) is very fuzzy. Due to Saturn's east-west wind, these layers are aligned with latitude.

Red and orange indicate that clouds extend upward into the atmosphere. Red clouds are even higher than orange clouds. The two areas with the densest storms near Saturn's equator are shown in white. On the earth, the storm with the highest cloud cover was also found in tropical latitudes. The smaller storm on the left is about as big as the earth, and the larger storm was recorded on Saturn in 1990 and 1994.

A ring made up of chunks of ice is as white as an ice image taken under visible light. But in infrared, water absorption will produce various colors. The most obvious is the innermost brown. The halo casts a shadow on Saturn. The bright line seen in the shadow is the interval between two bright rings when sunlight passes through the Cassini branch. It is best to observe on the left above the ring. This view is possible because there are few geometric shapes in the observation process. The accurate study of the ring shadow also shows that sunlight passes through the Enke gap, which is a tiny part very close to the outer edge of the ring system.

You can see Saturn's two moons, Titan on the lower left and Tethys on the upper right. Tethys has just completed crossing Saturn's disk. They are displayed in different colors of yellow and green, indicating that they are in different States on the ice.

M2-9 is a remarkable example of butterfly or bipolar planetary nebula. Another more conspicuous name may be "Gemini Cloud". If the nebula is cut on a star, each side of it looks very much like a pair of exhaust gases from a jet engine. Indeed, because of the shape of the nebula and the measured gas velocity (more than 200 miles per second), astronomers think it is appropriate to describe it as supersonic jet exhaust. Ground research shows that the size of the nebula increases with time, which indicates that the explosion of the star that formed the leaves occurred 1200 years ago.

As we all know, the central star in M2-9 is one of two very close stars, which surround each other at a dangerous close distance. It is even possible that one star is swallowed up by another. Astronomers suspect that the gravity of one star will pull out the weakly bound gas from the surface of another star and pounce on it, forming a thin and dense disk that surrounds the two stars and extends into space.

In fact, this CD can be seen in the short exposure image taken by Hubble Space Telescope. Its diameter is about 10 times that of Pluto. The model ("fluid mechanics") used to design the jet engine type shows that such a disk can successfully illustrate the jet-like exhaust appearance of M2-9. The high-speed wind from the star rushes into the surrounding disks, which are used as nozzles. The wind deflects vertically, forming a pair of jets that we see in the nebula picture. This is basically the same as the process in a jet engine: the burning and expanding gas is deflected by the engine wall through the nozzle, thus forming a high-speed, long and parallel hot air jet.

This image of the Hubble Space Telescope was released at 1996 to celebrate the sixth anniversary of the telescope. It shows several blue ring objects, which are actually multiple images of the same galaxy. They are copied by the "gravitational lens" of yellow, oval and spiral galaxy clusters near the center of the photo, and are called "0024+ 1654". Gravitational lens is produced by the huge gravitational field of galaxy cluster, which bends the light, thus magnifying, brightening and distorting the image of distant objects.

Light from distant galaxies will bend when it passes through clusters of galaxies. In this photo, the light from the Milky Way is divided into five independent images. Light also distorts the image of the Milky Way, changing from a normal spiral shape to a more round object. Astronomers determine that blue objects are duplicates of the same galaxy because they are similar in shape.

Although the gravitational bending process is well known, the high resolution of Hubble telescope reveals the structure in blue galaxies that astronomers have never seen before.

One of the most famous images of the Hubble Space Telescope, these gas and dust towers in the Eagle Nebula (M 16) are called "pillars of creation".

Pillars are similar to hills in the desert to some extent. Basalt and other dense rocks protect the area from erosion, and the surrounding landscape has been destroyed for thousands of years. In the case of this celestial body, a large number of hot newborn stars (located at the top edge of the picture) emit ultraviolet rays, especially dense molecular hydrogen and dust clouds, which survive longer than their surrounding environment. This process is called "light evaporation". This ultraviolet ray is also responsible for illuminating the tortuous surface of the cylinder and the ghost airflow boiling from its surface, producing eye-catching visual effects and highlighting the three-dimensional nature of the cloud. The tallest pillar (left) is about 4 light years long from the bottom to the top.

When the column itself is slowly eroded by ultraviolet rays, even denser gas balls will be found buried in the column. Embryonic stars are formed in at least some spheres.

This image of the center of the spiral galaxy Messier 100(M 100) was taken after the first maintenance mission of the Hubble Space Telescope, showing the remarkable improvement of the Hubble Space Telescope's field of vision. Hubble's line of sight was blurred when it was launched because its mirror was slightly defective. The astronauts who carried out the first maintenance mission installed a corrective optical system to make up for the defects, and used a new instrument-wide-angle and planetary camera 2-to correct its built-in defects. This photo was taken with a new instrument. M 100 is one of the brightest members in the Virgo cluster. Spiral galaxies have two prominent bright arms and several weak arms.

Anne Hathaway appeared on the red carpet in a low-cut dress. Judging from the close-up of high-definition pictures, what is her status? Recently, AnneHathaway appeared on the red carpet of an event in a beautiful dress. Everyone knows that the media in Europe and America will not give you pictures, so there are many pictures of Anne Hathaway, but the value of Anne Hathaway is overwhelming. Anne Hathaway looks confident and elegant and has a very mature charm.

First of all, it is said that Anne Hathaway is the most hated female star in the United States. Americans hate Anne Hathaway only because Anne Hathaway is perfect. Her figure and appearance should be a vase. As a result, AnneHathaway's acting skills are excellent. She even won an Oscar. She is even a good singer and dancer. Such conditions are really enviable.

Secondly, Anne Hathaway is now thirty-nine years old, and this age is middle-aged, so we can also see some traces of time from Anne Hathaway's life picture, but Anne Hathaway is well maintained, obviously Anne Hathaway is in very good condition, so even without collagen, she still looks very capable of playing, especially her confident and elegant temperament, which looks really comfortable.

Finally, AnneHathaway's figure is also quite beautiful. The proportion of the whole person's figure is too superior, and her body exudes the charm of intellectual maturity. Among enthusiastic Europeans and Americans, AnneHathaway is very oriental. It is said that time can't beat beauty. I think AnneHathaway is a typical example.
