Scientists found another Earth!What a discovery!!
Scientists have found super-Earth-class planets with Earth-like orbits



Scientists wonder if they discovered a mysterious extraterrestrial planet in a special way.

This planet is very noticeable, not only because it is somewhat similar to Earth in some ways, but it also has some significant differences. In terms of size, scientists think the planet is about four times the mass of the earth. The planet's sun is a dark dwarf star, and may even be a brown dwarf star, or "failed star". The planet year is about 617 earth days, but its orbit is roughly equivalent to the position between the Earth and Venus in our solar system.

However, the team of scientists who discovered this new extraterrestrial world did not directly observe it. It is not even determined by its interaction with the star. The researchers discovered this planet and its stars by bending and magnifying the light, just like a prism-this phenomenon is called a gravitational microlens.

This phenomenon is based on an implementation that mass objects will bend the space near themselves. When telescopes, massive objects and targets are aligned in an appropriate manner, the massive objects in the middle will bend the light emitted by the target and magnify it. According to a statement from the University of Canterbury in New Zealand on this new research discovery, this is a very rare event-it is rare that only 1 in a million stars will observe lensing at any time.

To discover the planet, the scientists combined the microlens observations of the following two institutions: Optical Gravitational Lensing Experiment in Poland, and Korea Microlensing Telescope Network in Chile, South Africa and Australia. (Korea Microgravity Lens Telescope Group).

Scientists can use the precise details observed by microgravity lenses to calculate the celestial body that acts as a lens-usually a single star. However, after analyzing the target brightness under the action of the microgravity lens and without it, the scientists found that this lens is actually a system, not a single star. To complete this great discovery, you need to carefully study the data within five days to isolate five hours of related observations, and then make sure that this unusual discovery is not due to an accidental error of the machine.

The result is a basic description of this long-distance star system: a star that is one-tenth the mass of the sun, and a planet that may be four times the mass of the earth-it can be regarded as super-Earth, or sub-Neptune -The orbital distance of this planet is between Venus and Earth. This combination is exciting because among the thousands of extraterrestrial planets discovered as of today, planetary worlds with such orbits are very rare.
