Chapter 1,236: The Vast Universe

"This is Jupiter, Mrs. Ye." The person who answered him was Mark who was at work.

He Xiyan took a deep breath.

At this time, she admitted that she was shocked. She had never studied geography and had seen photos of the eight planets in the solar system posted online, but this was the first time she had seen a celestial body under the lens of a telescope.

She could even see Jupiter rotating slowly, the atmosphere on its surface moving, and the huge cyclonic storm.

"Oh my God! Jupiter looks like this. It looks nothing like the photos posted online."

He Xiyan sighed, it was so spectacular and incredible.

Ye Hao was standing next to He Xiyan. As he expected, she would be excited and excited when she saw such a scene, just like when he saw it for the first time. However, he didn't see it when he came last time. Jupiter, because the telescope lens was not pointed in the direction of Jupiter at that time.

"How big is Jupiter?" He Xiyan forgot the geography knowledge she had learned. She only knew that Jupiter was the largest planet in the solar system.

"The mass of Jupiter is 2.5 times the combined mass of the other planets in the solar system, 318 times the mass of the Earth, and its volume is 1,321 times that of the Earth. The radius of Jupiter is one-tenth of the radius of the sun, and the mass is one thousandth of the mass of the sun. One." It was Ye Hao who replied, with a faint smile on his lips.

As long as she is happy, he will take her wherever she wants to go.

He Xiyan turned to look at Ye Hao, "You memorize it quite well."

He Xiyan really didn't realize that Ye Hao had been interested in astronomical observation before.

The observatory has the most advanced telescopes, including radio telescopes and space telescopes, which can see celestial objects more than 10 billion light-years away.

He Xiyan discovered that the screen next to him displayed beautiful clouds, colorful, lake blue, pink and pink, extremely dreamy. There were white, yellow, and blue point-like stars in the clouds. These should be stars.

He Xiyan stared at this beautiful picture for a long time with her eyes wide open.

"Where is this?" He Xiyan asked Dr. Mark beside him.

It's incredible that the vast universe is also so beautiful.

"This is the Trilobite Nebula, located deep in the Milky Way near the center of the Sagittarius constellation. It is about five thousand light years away from our earth."

"Five thousand light years?"

He Xiyan froze there as if she was stupid, staring straight at the dreamy picture on the screen.

Five thousand light years, she couldn't imagine how far away it was. She knew that it took 8 minutes for the sun's light to reach the earth. What was the concept of five thousand light years...

"Yes, this nebula is mainly due to the fact that there is an open star cluster inside it (a celestial body composed of hundreds or thousands of stars with weak gravitational connections) that uses radiation to strongly attack the hydrogen atoms in the nebula, causing them to After losing its own electron, when the electron combines with the proton, it will emit a stunningly beautiful light, so we can see the beauty of this object that can only be seen in the sky.

Mark explained. He spoke Chinese because he had lived in China for a long time. It's just that He Xiyan couldn't understand his professional explanation.

He Xiyan only knew that there were beautiful nebulae on the screen, and those light spots were stars, many, many stars.

"Are stars born in nebulae?"

He Xiyan asked Mark beside her like a primary school student. When she was little, she loved watching stars and thinking about strange questions.
