Trinity test: the nuclear detonation that changed the world | Digital Trends Spanish

Its code name was Trinity and it was held on July 16, 1945, a day like today 76 years ago. It was the first detonation of a nuclear bomb as a test and the first encounter of humanity with this type of weapons of mass destruction. The Trinity test was carried out in the New Mexico desert at 5:30 in the morning, in a sector so dry that it was known as the Jornada del Muerto. That detonation, which was successful, was marked by tragedy, because it conditioned what would happen less than a month later with Little Boy and Fat Man, the bombs that fell on Hiroshima and Nagasaki, respectively. In fact, the latter used plutonium as fissile material, the same one used in Trinity. Although official figures vary, it is estimated that between the two tragic events between 150,000 and 250,000 people...

China recreates Mars with a camp in the middle of the desert | Digital Trends Spanish

China has taken space exploration seriously. The Asian giant has just sent its Tianwen-1 mission to Mars, in addition to building its own space station. In the case of the red planet, since 2019 the country has a camp that simulates the environmental conditions of Mars. This project is located in the middle of the desert, in Qinghai province, in the northwest of the country. This area was chosen by the authorities due to its desert landscape, the abundant presence of rocks and its temperature that can be similar to that of the neighboring planet of the Earth. This field covers an area of ​​702 hectares and can host 160 people at the same time, according to South China Morning Post. The complex can house tourists and scientists who use the facilities to carry out preparatory work for e...

They record the volcanic impact of a moon of Jupiter | Digital Trends Spanish

Images obtained by the Atacama Large Millimeter / submillimeter Array (ALMA) show for the first time the effect of volcanic activity on the atmosphere of Jupiter's moon Io. With 400 active volcanoes that expel sulfur gases, Io is the most volcanically active moon in our Solar System. Precisely, these gases stain it yellow, white, orange and red when they freeze on its surface. The atmosphere of Io can give us important information about the volcanic activity of this unique satellite, as well as its interior and everything that happens under its crust. In order to distinguish the processes that give rise to Io's atmosphere, a group of astronomers used ALMA to obtain images of the satellite as it passed inside and outside of Jupiter's shadow. "As it passes through Jupiter's shadow an...

Identify millions of trees in the Sahara with AI | Digital Trends Spanish

If you are one of those who believe that the Sahara desert is covered only by sand dunes and stones, perhaps the time has come for you to put that notion aside: an international team has managed to identify more than 1.8 billion trees and shrubs in Africa Western. According to researchers from the University of Copenhagen and NASA, the area of ​​1.3 million km2 covers the westernmost part of the Sahara desert, the Sahel and what is known as sub-humid areas of West Africa. “We were very surprised to see that there are actually quite a few trees growing in the Sahara desert. Most people thought there were practically none. We count hundreds of millions of trees in the desert alone, "said Martin Brandt, a researcher at the University of Copenhagen and responsible for the study. The ...
