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...

Hubble detects an impressive Einstein ring | Digital Trends Spanish

A new photograph from the Hubble Space Telescope shows an impressive "Einstein ring" at a distance of billions of light years from Earth. The phenomenon is named after the famous physicist, who predicted that gravity could bend light. The round object that can be seen in the center of the image shared by the European Space Agency (ESA) corresponds to three galaxies that appear as if they were seven. The farthest galaxy, a very bright one with a gigantic hole at its center, is about 15 billion light-years from Earth. Although at that distance this object should be invisible, we can appreciate it, since its light is bent by the two galaxies in front, about 3 billion light years away. THIS.Thus, its image is shown as five different places: four times in the ring and once in its center, alt...

The universe keeps getting hotter | Digital Trends Spanish

Research by the Ohio State University Center for Cosmology and Astroparticle Physics examined the thermal history of the universe and concluded that it is getting hotter and hotter. The work was published in the magazine Astrophysical JournaLy determined that the temperature of gas throughout the universe has increased more than ten times during the last ten billion years, reaching approximately 2.2 million degrees Celsius. “As the universe evolves, gravity pulls dark matter and gas into space to form galaxies and galaxy clusters. The drag is violent, so violent that more and more gas is discharged and heated, ”explains Yi-Kuan Chiang, lead author of the study. The researchers used a new method that allowed them to estimate the temperature of the gas farther from Earth. This mean...

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...

Hubble Telescope: the most impressive images captured in its 30 years | Digital Trends Spanish

Hubble reached the milestone of 30 years in orbit in 2020, leaving us with the most incredible astronomical images ever captured, profoundly changed, incidentally, our understanding of the cosmos. Some of the telescope's most impressive images of space are well worth a look. This list, for now, goes from the photo celebrating 30 years of the space instrument to the one showing the Arp 273 group of galaxies. Cosmic Reef or Cosmic Reef (2020) NASA, ESA, and STScI This is the image that celebrates Hubble's 30 years in space: Cosmic Reef or Cosmic Reef, which refers to an underwater world. "It shows how massive, energetic, young stars light up and sculpt their birthplace with powerful winds and scorching ultraviolet radiation," according to NASA. Pictured are the giant re...
