Announcing more new findings about Mercury

Scientists have just added new discoveries about Mercury, the closest planet to the Sun but also contain the most mysteries for humans.

>>>Discover Mercury from Messenger spacecraft

This discovery was published in the American Journal of Science on September 29, after the probe ship Messenger (NASA) for the first time in astronomical history (NASA). successfully flew into Mercury orbit at the beginning of the year.

The data collected from the Messenger ship once again confirmed the scientific hypothesis from more than three decades ago that volcanoes created flat plains in the north on the surface of the planet, but at the same time. Revealing more interesting discoveries.

Experts say that about 4 billion years ago, lava flows erupted after volcanic activity on Mercury created flat plains that accounted for 6% of the planet's surface area. , equivalent to 60% of the US area.

In particular, the volcano here has a very different shape than the volcano commonly found on Earth, with a narrow crater and stretching like a river containing lava.

Craters, with a length of up to 25km and a depth of up to 2km, erupt lava across the surface of Mercury, creating valleys and mounds in areas with many holes and deep trenches.

According to the US Geological Survey (USGS), on Earth, oral volcanoes like these cuts are known as badan mineral deposits found in the western United States, forming land along the Columbia River. in Washington and Oregon about 12-17 million years ago.

The scientists' findings also suggest that Mercury often suffers from solar winds, a flow of charged particles released from the upper part of the Sun.

In addition, there is no atmosphere on Mercury, so the temperature difference here is very large. The highest temperature is up to 430 degrees Celsius, but it can be lowered to 170 degrees Celsius when the planet revolves around the motion axis. It is also the only planet near the Sun that has a magnetic field around it, but the magnetic field is so weak that it cannot create a shield against the Sun's radiation.

Messenger probe was launched by NASA in August 2004 in a project worth up to 446 million USD. The ship has successfully advanced into Mercury orbit after a six-year journey.

So far, Messenger has been flying more than 7.8 billion kilometers, flying more than 15 rounds of the Sun. During her journey, the ship flew over Earth once, twice flew through Venus and 3 times flew through Mercury.

Mercury is the smallest planet in the Solar System, about one third the size of the Earth. So far only people know very little about this planet.

The first full-scale map of Mercury was only built in 2009 with the probe data of "Mariner - 10" studying the planet in the 1970s.

Mercury is the only planet in the planets that are visually visible without artificial satellites.
