Kepler Telescope Detects Four New Rogue Planets | Digital Trends Spanish

Thanks to the now retired Kepler telescope, a series of rogue planets have been discovered that float through space without rotating around any stars. These planets are located near the center of the Milky Way and were discovered using data obtained by the telescope. There are four planets in total and the information obtained revealed that they have a mass similar to that of Earth. According to what was published in PhysThese planets may have been part of a system around a star until they were expelled from it by the gravity of other larger bodies. Now, one of the biggest curiosities has to do with the way these planets were discovered. NASA Ames / SETI Institute / JPL-CaltechIn this case, the existence of the bodies was detected thanks to what is called gravitational microlensing, a...

Mysterious radio signal traced inside our galaxy | Digital Trends Spanish

An international team of scientists managed to track down mysterious and intense bursts of radio energy that could come from inside the Milky Way. These Fast Radio Bursts (fast radio pulses or FRB), usually last only a fraction of a second, but can be a hundred million times more powerful than the Sun, according to the researchers. They used telescopes and technology from different countries, including Canada, the United States, and China to carry out their observations. They recently reported the detection of an FRB originating 30,000 light-years away in the northern Milky Way. This would be the first FRB detected within our own galaxy. According to astronomers, it would originate from a highly magnetized object, known as a magnetar (stars with a very powerful magnetic field). "W...

NASA creates list of the most disturbing sounds from space | Digital Trends Spanish

The world prepares for a new Halloween celebration. This will be a different version, yes, due to the worrying pandemic that affects the planet. For this reason, the way of celebrating has changed and we may have to spend more time at home during this traditional celebration. The good news is that the panoramas are not going to be missing and they may come from the most unusual places. From space, for example. The National Aeronautics and Space Administration (NASA) has launched in Soundcloud a special list that brings together the scariest sounds obtained from space. As reported in a release, this list "is full of new moans and whistles from our universe that would scare even the most macabre creatures." The compilation includes sounds derived from the tremors on Mars, detected ...

They get an impressive map of the halo that surrounds Andromeda | Digital Trends Spanish

A group of astronomers managed to map for the first time in history the immense envelope of gas, called the halo, that surrounds the Andromeda galaxy, the closest galactic neighbor of the Milky Way. Using data from the Hubble telescope, the scientists discovered that the faint and almost invisible halo of diffuse plasma extends 1.3 million light-years in some areas, up to 2 million light-years elsewhere. This means that the Andromeda halo is colliding with that of the Milky Way. Another finding was that they discovered that the halo has a completely different structure of two layers: an inner, more complex and dynamic, and an outer, softer and warmer. "It is full of clues about the past and future evolution of the galaxy, and we can finally study our closest galactic neighbor in gr...
