55 million kilometers away, the probe sent back data that monitored 500 earthquakes on Mars
The closest distance between Mars and Earth is more than 55 million kilometers, and the farthest is 400 million kilometers, which seems very distant, but currently, there are already many rovers operating on the surface of Mars, in addition to the three new rovers that arrived on Mars this year, there are also the Curiosity rover and the Insight rover to probe on the surface of Mars. Among them, the Insight rover was launched on May 5, 2018, and successfully landed on the surface of Mars on November 26, 2018, this rover is the first rover used by our humans to explore the interior world of Mars, which can probe the size, composition and physical state of the Martian core, geological formations, and also detect the temperature and seismic activity inside Mars. Since landing on Mars, the Insight rover has repeatedly monitored the occurrence of earthquakes on Mars.

Everything in the universe is fixed in an endless cycle, researchers: is there something else about the origin of the universe?
We have always had an unresolved confusion - where did the universe come from? And where did we humans come from? Although we are scientists to come up with "evidence" to tell the universe from the singularity of the big bang, and human evolution from the ape, not all people on earth believe the scientist's "testimony". Those places with ancient cultural heritage would rather believe that the universe and human beings were created by "God" than believe the scientific explanations of scientists.

This kind of goose was once an endangered species, but now people have to give them family planning again.
Originally a migratory bird, the goose migrates back and forth between Canada and the United States every year, thanks to its huge size (wingspan 1.27 to 1.85 meters, weight 2.6 to 6.5 kilograms) and its natural aggressiveness, it has few natural enemies in adulthood, only hyenas, gray wolves, golden eagles, sea eagles, snow owls and so on. As a result, their original habitat is so vast that they can be seen from northern North America to areas close to Central America.

Spooky photos were taken on Venus, and moving objects appeared on the surface, causing a stir in the scientific community
The eight planets in our solar system are unique in appearance and size, and although Earth is not the largest one, it is one of the most special because this planet has land and oceans on its surface, and there are also many green areas on the land, a feature that the other planets do not have. At one time, Venus was seen as a sister planet to Earth because the two are more similar in many ways. For example, Venus has 0.82 times the mass of Earth, 0.95 times the radius of Earth, and 0.9 times the gravity of Earth.
