What is the farthest flying aircraft that human beings have ever flown?

A spaceship flying farther and farther.

Explanation: What is the farthest spaceship that humans fly? The champion belongs to 1 voyager launched in 9771. It is now 0.75 billion kilometers away from the sun/kloc-0, which is equivalent to 16 light or 1 17 astronomical unit (AU). This picture shows the position of Voyager 1 relative to the outer solar system and other distant spacecraft. The runner-up is Pioneer 10, which is about 154 billion kilometers away, and is located on the other side of the solar system compared with Voyager 1. In addition, there are Voyager 2 and Pioneer 1 1, which are far away from Pluto's orbit, and the distances from the sun are 142 billion kilometers and 124 billion kilometers respectively. The New Horizon spacecraft is currently 3 billion kilometers away from the sun and will reach the Pluto system in July 2065438+2005. All these spacecraft use gravity slingshot mode to accelerate through the outer solar system. Voyager 1 is the fastest and escapes from the solar system at a speed of 17 km per second. Both Voyagers are heading for the outer boundary of the solar system.

Little Beidou

Explanation: As a second-class star, Polaris is definitely not the brightest star in the night sky, but in this starry sky image covering about 23 degrees, Polaris on the left is definitely the brightest star in the picture. This image shows the main bright stars in the constellation Ursa minor where Polaris is located. They also form a bucket shape, commonly known as "Little Beidou". The famous Polaris is a friend of navigators and astrophotographers, but it is not completely located in the north celestial pole, and it is currently deviated by about 0.7 degrees. Sliding the mouse in the above picture will give the names of other stars (see the original picture, which cannot be shown here), including their real names and the numbers of Greek letters.

The Secret of Super Telescope

Explanation: What is the bright orange spot above the large telescope on the right (third from the right)? This wide-screen image was taken last year1February, and even experienced sky lovers will ponder the origin of orange spots. It is very interesting to identify known celestial bodies. The leftmost diagonal band of light is called zodiacal light, which is sunlight reflected by dust inside the solar system. The bright white spot on the left horizon is Venus, which can also be seen by reflecting sunlight. The most prominent diagonal band of light in the center of the image is the Milky Way, which usually unfolds grandly above our heads and seems to arch over the undulating terrain of Chile. Below the arched Milky Way, the Magellanic Cloud, large and small, is on the left, and the Orion Cloud, surrounded by the red halo of Barnard Circle, is on the right. On the ground, four very large telescopes (VLT) are busy observing the distant universe. Now the answer can be announced. The orange spot is the moon! This photo was taken during the total lunar eclipse, and the bright full moon turned into dim orange spots due to the reflection of the earth's atmosphere.

The straw hat galaxy photographed by Hubble

Explanation: What happened at the center of this spiral galaxy? M 104, also known as the straw hat galaxy, has a striking dust channel and a bright galactic halo composed of stars and globular clusters. The straw hat galaxy has such a special appearance because it has a particularly huge central core ball, and the dark dust belt just appears in the disk facing us. Billions of ancient stars have produced the scattered glow of the central core ball. Looking closely at the nuclear sphere in the above picture, many light spots are actually globular clusters. There are many young and bright stars in the spectacular dust belt of M 104, showing many interesting details, many of which have not been fully understood so far. The center of the straw hat galaxy is thought to have a big black hole. The straw hat galaxy is about 50 million light years away from us, and it can be seen in the direction of Virgo with a small telescope.

The "cliff" in the south of the lagoon nebula

Explanation: The above picture shows the nearby star-forming area M8, also known as the lagoon nebula. There are undulating ridges and dust clouds in this close-up photo. This clear pseudo-color image was taken by the 8-meter Southern Gemini Telescope, which consists of narrow-band visible light image and broadband near-infrared image. The whole field of view covers about 20 light years, showing an area called "South Cliff" in the lagoon nebula. Detailed images show the connection between many newborn stars hidden in the cloud tips and Herbie-Harrow celestial bodies (HH). HH celestial bodies are very abundant in the star formation area, which is produced by intense radiation jet heating the surrounding gas and dust clouds during the formation of young stars. This cosmic lagoon is about 5000 light years away from us, located in Sagittarius.

Globular cluster M 15

Explanation: These stars surround the center of the bright globular cluster M 15 like bees. This big ball with hundreds of thousands of stars is a relic of the early Milky Way, which has been running around the center of the Milky Way until now. M 15 is one of the only remaining 150 globular clusters. There are many stars densely distributed in its center, as well as many unusual variable stars and pulsars. The above picture was taken by Hubble Space Telescope, covering a range of 120 light years, and showing a trend that more stars are closer to the center of the cluster. M 15 is located in Pegasus, about 35,000 light years away. Scientists believe that there may be a huge black hole in the center of M 15.

The shadow of Mars Opportunity

Explanation: The huge shadow in the above picture comes from the rover Opportunity, which is currently exploring Mars. Opportunity and Spirit have been exploring this red planet since the beginning of 2004, and found evidence of ancient water, and sent back many amazing images of the inner solar system. Above, Opportunity stares at the crater and its own shadow with its back to the sun. Two wheels can be seen at the lower left and right, and the bottom and wall of the crater can be seen in the background. Although Spirit is in trouble now, Opportunity is still on a long journey to Endeavour Crater.

Navigator 1 The Great Red Spot in the Eyes

Explanation: This huge typhoon system can plug two earths. Since it was first observed with a telescope, this huge typhoon shows no signs of slowing down. This is Jupiter's Great Red Spot and the largest vortex storm system in our solar system. The Great Red Spot, like most astronomical phenomena, cannot be predicted and understood immediately after discovery. To this day, the real reason why the Great Red Spot changed its appearance, size and color is still very mysterious. This picture was taken in 1979, when Voyager 1 was near the largest planet in the solar system (Jupiter), and it was digitally made later. The current traveler 1 is about 1 17 AU from the earth. It is the man-made object that has sailed farthest so far and may leave the whole solar wind sheath at any time.
