Scientists can find the first extraterrestrial satellite: "very suitable for living" – Scientific discovery – cnBeta.COM



On the 28th of November in Beijing, the extraterrestrial satellite refers to a satellite that is called a "exoplanet" that surrounds a certain planet outside the solar system. Since 2009, the National Aeronautics and Space Administration (NASA) Kepler and Transit Excavator Satellite (TESS) mission has discovered about 4000 foreign planets, but astronomers have only one off-plane satellite. I was explained and not sure whether there is still satellite.

The Ekoplane Kepler-1625b and probable satellites are estimated to be similar to Neptune size. Researchers have said that this potential satellite and other extraneous satellites could even have their own satellites.

In October 2018, David Kipping and graduate student Alex Teachey, an astronomer at Columbia University, first reported this to Science Advances. It's a potential satellite.

Two researchers using NASA's Hubble Space Telescope analyzed observations when a Kepler-1625b (Kepler-1625b) star equals an equator. This is a planet similar to the size of Jupiter; this prevents some of the light from passing through the star. By analyzing the star light curve, the properties of the planet can be determined.

This method of observation is called the transition (occlusion) method. Astronomers used this method to explore thousands of ecstopeth. However, researchers found two surprises when observing the Kepler-1625b process flying over the star. First, the outer planet showed that the star had flown 1.25 hours before expected, and that something created gravity traction. Secondly, after the planet has completely passed out of the star, a very shallow gap appears in the light curve indicating that there may be a satellite behind the Kepler-1625b.

David Kiping said: "We have excluded other possibilities, such as detector errors, activities of other planets in the system, or other star activities, but we cannot find another hypothesis that could explain our hands. All data."

This potential extraterrestrial satellite is about the same size as Neptune with about a third of the Kepler-1625b. The size of a typical satellite is usually much smaller than the orbiting planet, so this is quite surprising. In the case of the present planetary satellite system formation model, such a satellite should be seen very rarely.

The quality of the Kepler-1625b is assumed to be several times the value of Jupiter and the quality of the potential satellite is assumed to be only 1.5%. This mass ratio is similar to Earth and Moon. In the Earth and Moon system, it is thought that the moon is formed by the debris of rocky planetary collisions. Astronomers, however, believe that Kepler 1625b and its probable satellites belong to a gaseous planet and not consist of rocks, so this extraterrestrial satellite may have been formed by different processes.

”Now we can't rush to open champagne celebrations, Alex Alex Titcher said, ed But everything looks exciting, attractive and convincing.“

Looking for life on a satellite outside the camera?

Some scientists claim that extraterrestrial satellites can be a ğ very livable Bazı world, meaning they are good places to live. The reason is that these satellites are not limited to the use of light energy from the main stars in the system, but on the contrary, they can obtain energy from other places:

Reflected light. Light or thermal radiation reflected from nearby planets can provide long-term stable temperatures and promote the evolution and proliferation of life.

Radioactive element. Radioactive elements such as uranium and thorium can exist deeply in rock formations of extraneous satellites of similar Earth, and over time these elements gradually slow down and release heat to the satellite surface.

Tidal power. The gravitational attraction of a large outer-spatial attraction, such as the size of Jupiter or Saturn, can include extraterrestrial satellites, which can create tidal forces similar to tidal changes produced by the gravitational pull of the Earth. When the surfaces of extraterrestrial satellites are drawn by the gravitational pull of external planets, the resulting heat may reach the satellite surface.

There are about 175 satellites in our solar system. Most of these satellites have these features, and both are strong candidates for finding extraterrestrial life: Jupiter in satellite Europa's water (Meowe) and Saturn's satellite Enclades (Luke).

Both satellites have a frozen surface covered with striped strips formed at temperatures not exceeding 128 degrees by the gravitational forces of the planet. However, only a few kilometers below the surface, there is a large liquid ocean-containing liquid water that exceeds the total amount of water on the earth. When liquid water is present, it can be life.

Where are the other satellites out of band?

Some astronomers predict that there may be many frozen satellites with a subterranean ocean in the Milky Way, which may be 100 to 1000 times larger than terrestrial planets, but which are very difficult to find.

The main star of Kepler-1625b is a distance of about 8,000 light-years away from the Earth, making it a very small point on Earth, but with advanced detection techniques, scientists can notice their weakness as they pass by the planet. . For Kepler-1625b, it is relatively easy to detect due to the large size of the satellite. However, for non-plane satellites of similar size to Europa, which is equivalent to a quarter of the Earth's volume, it is not so easy to detect the hac gap ine signal they leave as they pass by the star. Under the present technical circumstances, these deficits are too small to be clearly identified. Therefore, it takes a little more patience to find extraterrestrial satellites.
