Two galaxies hidden by stardust have been discovered | Digital Trends Spanish

An international team of astronomers discovered two galaxies that existed in a period of the universe close to the Big Bang. Valentino González, an astronomer from the Faculty of Physical and Mathematical Sciences of the University of Chile, pointed out: "We discovered two galaxies that had an impressive amount of dust, they were literally hidden / covered from a normal optical observation, that is why it was thanks to the ALMA radio observatory, with its sophisticated equipment, that we were able to discover them." Stardust is a set of particles made up of various chemical compounds, which can be found in almost all galaxies. University of Chile.However, their formation takes time and is not expected to be as abundant at the 700 million years of the universe (which is the time in which...

The best images of the astronomical photography contest | Digital Trends Spanish

The space always offers us the most spectacular views. Fortunately, cameras have evolved so much in recent times that they can now capture that spectacularity. The Astronomy Photographer of the Year 2021 contest brings together the best images of the sky and space, and this week has announced the winners. The event organized by the Royal Observatory Greenwich is one of the most attractive events for lovers of astronomical photography and many people submit their images to compete. The competition is divided into eight categories: auroras; galaxies; our Moon; our Sun; people and space; planets, comets and asteroids; heavenly landscapes and stars and nebulae. This year, the main prize went to Suchang Dog and his photograph The Golden Ring, which shows an annular solar eclipse captu...

Sun-like stars devour planets | Digital Trends Spanish

New research by Italian astronomers found that large numbers of Sun-like stars have devoured some of the planets around them. The study was published in Nature Astronomy and led by Lorenzo Spina, an astrophysicist at the Astronomical Observatory of Padua, in Italy. One of the main results indicates that up to a third of stars similar to ours have already swallowed their planets. According to the authors, this discovery could help rule out star systems that no longer contain Earth-like worlds. According to the researchers, when a planet is eaten, its heavy elements, such as iron, silicon and titanium, are scattered through the outermost layers of the star, and can be detected by astronomers looking for their own light absorption signals. of those elements. "If a star is abnormally rich i...

NASA shares an incredible flyby over Venus | Digital Trends Spanish

A few days ago, the Solar Orbiter and BebiColombo probes carried out a historic flyby over Venus. We have now seen an impressive record of this procedure. Of course, the most striking thing about the video is the appearance of Venus, defined by NASA engineers as a huge flashing ball approaching at full speed. It looks this bright because the planet's body is reflective, in part, to its dense atmosphere, which is covered in thick CO2 clouds. These clouds are capable of reflecting more than seventy percent of the solar radiation that arrives from space. To get an idea: the Earth reflects just under 40 percent. "Ideally, we could have resolved some features on the night side of the planet, but there was too much signal from the day side," explains NASA astrophysicist Phillip Hess in a sta...

What are dancing ghosts discovered in space? | Digital Trends Spanish

Astronomers from the University of Western Sydney and the Australian Science Agency (CSIRO) have detected strange clouds of electrons surrounding galaxies in the deep cosmos. These clouds would be about a billion light-years away and had never been seen before. According to scientists, they would resemble two dancing ghosts. These dancing ghosts were discovered as part of the first deep-sky search using CSIRO's ASKAP (Australian Square Kilometer Array Pathfinder) radio telescope. “We are getting used to surprises as we scan the skies as part of Project EMU and probe deeper into the Universe than any telescope before it. When you go boldly where no telescope has gone before, you are likely to make new discoveries, "the researchers explain in a statement. Western Sydney University.“When...

Aliens would use the stars to communicate | Digital Trends Spanish

It is possible that when we see the stars twinkling, aliens are communicating with each other. So at least one physicist at Imperial College London suggests. It is about Terry Rudolph, who a few days ago published an investigation where he proposed that an advanced extraterrestrial civilization could alter the light emitted by the stars to communicate at a great distance, almost as if they were sending smoke signals at an interstellar level. According to the researcher, the idea behind this proposal is to use entangled photons from different stars to transmit messages that look like random flickers to anyone. Getty Images.This idea, according to Rudolph, is possible from a physics point of view, but it becomes pure speculation when it comes to any discussion of alien technology. Also, ...

This planetarium with 10K technology was a war bunker | Digital Trends Spanish

The historical memory center La Coupole Planetarium, a former World War II bunker, announced that its planetarium will offer visitors the possibility of traveling through the universe through a 360-degree environment thanks to Sony's VPL-GTZ380 resolution projectors. Thus, the venue becomes the world's first 3D 10K planetarium. La Coupole is a huge bunker complex near Saint Omer in France that was built by the Nazis to launch V-2 rockets aimed at London during World War II. Now a new digital system has been installed in the museum's planetarium and RSA Cosmos has taken it upon themselves to improve the quality of the 3D immersive experience. From the enclosure they assure that it is the first in the world to offer 10K 3D images in the meridian. Thus, visitors are promised "ultra-realis...

Some exoplanets may be watching us | Digital Trends Spanish

It is possible that our planet is currently being observed from billions of kilometers away. Is it a disturbing idea? A group of astronomers has pointed out that some exoplanets, that is to say planets beyond our Solar System, have a direct line of sight to observe the biological properties of the Earth from very far away. Astronomers from the Carl Sagan Institute of Cornell and Lehigh University have identified 1,004 stars similar to our Sun that could contain Earth-like planets that would be able to detect the chemical traces of life on our planet. The article was already published in the Monthly Bulletin of the Royal Astronomical Society and is titled "What Stars Can See Earth as a Transiting Exoplanet?" "Let's reverse the point of view of other stars and ask from what point of...

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...

Look at NASA’s Amazing Kepler Supernova Explosion | Digital Trends Spanish

In 1604, astronomers saw the explosion of a star that destroyed it, known as Kepler's Supernova, named after the famous German astronomer Johannes Kepler. More than four hundred years later, the debris from that explosion is still visible. NASA, from the Chandra X-ray Observatory, has captured this remnant of the detonated star that is about 20,000 light-years distant from Earth in our galaxy, the Milky Way. The images of the expanding remains of Kepler's supernova were taken for almost 15 years, and with them they have verified that the movement of the debris has not slowed down, it is still moving at about 37 million miles per hour, which is the highest speed recorded during NASA observation. The average speed of the knots is about 16 million kilometers per hour. In the video,...
