The reddest galaxies with a larger central bulge have the longest bars, gigantic central columns of stars, and dark matter. This is reflected in a scientific study by researchers from Europe and the US in which the Google Maps service has been used to observe the sky. The results of the most precise measurements - corresponding to 3,150 galaxies - have been published in the Monthly Notices of the Royal Astronomical Society.
A new technique consisting of joining radio telescopes from all over the world that work together, focusing simultaneously on the same source and simulating a single gigantic telescope has made it possible to obtain high-resolution images of distant galaxies.
Thanks to the Gran Telescopio Canarias (GTC), a pioneering study led by the researcher from the Instituto de Astrofísica de Canarias (IAC) Carlos M. Gutiérrez has identified three compact groups of galaxies located about five billion light years from Earth.
A study of 200,000 galaxies over five years, dating back seven billion years in cosmic time, has yielded one of the best confirmations that dark energy is driving our accelerating universe.
An international team of astronomers has determined for the first time the amount of dark matter that was needed in the origins of the Universe for the formation of galaxies like the Milky Way: around three hundred billion times the mass of the Sun.
Researchers at the University of California in Santa Cruz (United States) have detected a galaxy with a redshift of approximately 10, which corresponds to a time when the Universe was about 500 million years old.
NASA's WISE infrared space telescope has captured a new view of two companion galaxies that show stark morphological differences: a quiet spiral beauty and a fiery, smoky beauty in which new stars form.
American astronomers have discovered that the small, faint stars known as "red dwarfs" are much more prolific than previously thought, to the point that the total number of stars in the universe could be three times higher than estimated.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
