Remains of a flying dragon identified in Chile | Digital Trends Spanish

Thanks to the study of the fossil remains found in the Atacama desert (northern Chile), in 2009, a strange “flying dragon” from the Jurassic could be identified, something that had never happened in the southern hemisphere. It is a type of pterosaur belonging to the subfamily Ramphorhynchinae, which was found in the city of Calama and which inhabited Gondwana about 160 million years ago. The study was headed by Jhonatan Alarcón, researcher at the Paleontological Network of the University of Chile, and the remains that corresponded to “a left humerus, a possible dorsal vertebra and two fragments of a phalanx of the wing, all preserved in three dimensions and probably belonging to a single individual ”. University of Chile.According to the scientist, the preserved pieces of the specimen a...

This unpublished image shows an exoplanet in full formation | Digital Trends Spanish

A group of astronomers has discovered what could be a region of exoplanets in formation. Scientists found the dusty disk around a young exoplanet in a solar system called PDS 70 located 370 light years away. The team found the first protoplanet using the Very Large Telescope at the European Southern Observatory in Chile. A year later, they found another young gas giant using the same equipment. Astronomers believe that the star system is only 10 million years old and that both gas giants are several times larger than Jupiter. ALMA (ESO / NAOJ / NRAO) / Benisty et al.To learn more about this system, the researchers focused on it all possible instruments, including the Atacama Large Millimeter / submillimeter Array (ALMA), which is made up of 66 short-wavelength radio antennas. Thus, t...

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...

Baby stars wrapped in salt water vapor recorded | Digital Trends Spanish

The ALMA (Atacama Large Millimeter Array) observatory, located in the Atacama Desert, in northern Chile, has revealed a pair of massive baby stars growing in a salty cosmic soup 9,500 light-years away, according to an article by EurekAlert. According to information from the observatory, each star would be surrounded by a gaseous disk that includes sodium chloride molecules, popularly known as table salt, and hot water vapor. The team in charge analyzed the radio emissions from the salt and water and found that the discs rotate in opposite directions. Image: ALMA. This would be the second detection of salt around massive young stars, confirming that salt is a good marker for exploring the surroundings of giant baby stars. Massive stars are those that when formed have a m...
