James-Webb would already break the Hubble record for the most distant galaxy ever observed!

We know that James Webb Space Telescope has a mirror greater than that of Hubble which allows him to see further and better than Hubble in L’infrared. But to have access to layer oldest light of cosmos observables, both instruments must use strong gravitational lensing. As part of the Glass Observation campaign (Grism Lens-Amplified Survey … Read more

Our body would be made of star dust

At first glance, astrophysics and medical pathology have little in common. What can the relationship between sunspots and age spots be? How could the Big Bang be associated with cystic fibrosis? In their book with the title Living with the stars: How the human body is connected to the life cycles of the earth, the … Read more

Discovery of an ancient galaxy beginning its rotation

Scientists have just discovered galaxy farthest rotation ever observed. It crossed over 13.26 billion light-years before it reached us, and is called MACS1149-JD1, abbreviated to JD1. But what makes it special is its rotational speed : JD1 rotates much slower than rotating galaxies from a less ancient time. ” That rotational speed of JD1 is … Read more

This is the most distant rotating galaxy ever observed

Scientists have just discovered galaxy farthest rotation ever observed. She crossed more than 13.26 billionlight years before it reaches us, and is called MACS1149-JD1, abbreviated to JD1. But what makes it special is its rotational speed : JD1 rotates much slower than rotating galaxies from less ancient times. ” That rotational speed of JD1 are … Read more

Alma and the Subaru telescope on the trail of the enigmatic killers of Urgalaxes

almost a century ago, Edwin Hubble opened the realm of galaxies to us by showing it mists in the astronomer’s famous catalog Charles Messiersuch as Messier 31 and Messier 87were actually objects outside The Milky Way and that they must therefore be like the Universes, in the sense of Edge in a pamphlet from 1755, … Read more

Mystery: why are these two galaxies devoid of dark matter?

Half a century after Rubin’s work, astronomers have still not been able to directly observe dark matter. It neither emits nor reflects light. It does not interact directly with ordinary matter, although its gravity affects the behavior of observable objects such as stars and galaxies. Scientists also believe that dark matter is needed for galaxies … Read more

Stars in distant galaxies are more massive than those in the Milky Way

In the early 1930s, the ingenious physicist Paul Diracone of the founders of Quantum mechanicswhich allowed him to theoretically discover the existence of antibody, had advised the very young Subrahmanyan Chandrasekhar to continue his education by spending time in Denmark at the Niels-Bohr Institute. It was founded in 1921 for physicist dansk Niels BohrThe Nobel … Read more

Dwarf galaxies around the Milky Way shed light on its complex past

On the sidelines of the Gaïa mission, by studying the dwarf galaxies orbiting the Milky Way, American scientists noted that the majority of these galaxies had only recently arrived in the area. This discovery has implications for our understanding of the interplay between normal galaxies and dwarf galaxies, and raises questions about the “life expectancy” … Read more
