Astronomers discover a new type of supernova | Digital Trends Spanish

A group of astronomers have found evidence that a black hole or a star of neurons spiraled into the nucleus of another and caused it to explode as a supernova, phenomena that had never before been identified. For this discovery, the team in charge used data from the VLASS (Very Large Array Sky Survey) sky observation project, which has as one of its objectives to find transient objects. According to astronomers at Caltech, it is normal for massive stars to explode as a supernova when their nuclear fuel runs out, but in this case, a black hole or neutron star caused the companion star to go supernova before weather. This discovery marks the first time that a supernova caused by a merger has been confirmed. Bill Saxton."Theorists had predicted that this could happen, but this is the first...

They find the largest crater of the last hundred thousand years | Digital Trends Spanish

A group of researchers has discovered in China the largest crater left by a meteorite on Earth in the last hundred thousand years. The formation is located 19 kilometers northwest of Yilan City (Heilongjiang) and measures 1.85 kilometers in diameter and has a depth of 579 meters. Only a portion of the crater is eroded, while the other two sections of the rim are well preserved, with a maximum elevation above the crater floor of 150 meters, according to the scientists. According to the Xinhua news agency, the Yilan crater was formed on a Cretaceous granite bedrock. For now, more studies are required to know the exact date of its formation.

This unpublished image shows an exoplanet in full formation | Digital Trends Spanish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