Scientists find water on Mars; see more discoveries that have moved astronomy

A group of scientists detected a large lake of liquid water under the polar ice caps of Mars. According to the authors, published Wednesday, 25, in the journal Science it is the first time that a large reservoir of liquid water has been identified in the red planet. Recently, other discoveries have moved the world of astronomy.

In February 2016, American scientists announced a historic discovery: for the first time, the gravitational waves predicted by Albert Einstein in his theory of general relativity, published a hundred years ago, were detected. The research was attended by over a thousand scientists from 14 countries, including Brazilian groups led by Odylio Aguilar of the National Institute of Space Research (INPE) and Riccardo Sturani of the International Center for Theoretical Physics of the University of the State of São Paulo (Unesp)

An international team of researchers discovered that the dwarf planet Ceres contained organic aliphatic remains – chemical compounds capable of developing life – and determined that this material did not come from the outside of the asteroid but there is formed there. Scientists announced on February 22, 2017 the discovery of a system with seven planets of size comparable to that of the Earth, in the orbit of a "neighboring" star of the Earth.

Solar System According to the study published in the journal Nature, the six planets closest to the star have temperatures between 0 and 100 ° C – a characteristic considered indispensable to the l? possible existence of life.

New Candidates

NASA's Kepler satellite announced last June that 219 new candidate planets have been cataloged, 10 of which are similar in size to the Earth and are in the so-called habitable area – this is the case. that is to say that they are at a distance from their star would theoretically allow the existence of liquid water on its surface – an indispensable feature for the existence of life.

The water on the moon?

A study using satellite data shows that several volcanic deposits distributed on the surface of the Moon contain large amounts of accumulated water compared to adjacent lands. The discovery of water in these ancient deposits supports the idea that the lunar mantle is surprisingly rich in water, according to the authors of the research published in the journal Nature Geoscience last July

19659003] After having spent 13 years exploring Saturn and its various moons, NASA's Cbadini spacecraft did not even plunge last September into the atmosphere of the planet and was devoured by the flames. Cbadini began his mission in 1997 and went into orbit in 2004. "It was the last chapter of an incredible mission, but it's also a new start. Cbadini's discoveries, such as the oceans on Titan and Enceladus, have changed everything by shaking our points considering these new potential places for the pursuit of life, "said NASA's scientific advisor Thomas Zurbuchen.

Star Collision

In October 2017, A large international group of scientists has announced the historical detection of a set of astrophysical phenomena never seen before.The researchers were able to grasp the collision of a pair of neutron stars – one of a kind. the most violent events in the Universe – which produced both the emission of gravitational waves, a powerful torrent of gamma rays and a luminous explosion a billion times brighter than the sun. [19659004] Several moons [19659002] Twelve new moons were discovered in orbit around the planet Jupiter, increasing to 79 the total circulating gaseous giant. It's the largest amount of moons around a planet in our entire solar system. Saturn, ranked second, has 61. The discovery was announced in July of this year by astronomers at the Carnegie Institution for Science
