We begin to discover wandering black holes whizzing through the Milky Way

That stars over 8 masses will not end with white dwarf but explodes supernovae SNII. Those with masses greater than 20/30 solar masses should not shed enough fabric in the explosion so thatcollapse gravity most often gives one neutron star, but rather a star-sized hole. The observed masses have between 5 and 15 solar masses. … Read more

great discoveries are on the way, some of which will challenge our knowledge

If all of us interested in space science wait first images from the James-Webb Space Observatory which will be published on 12 July – Community by astronomers is thrilled and amazed today at the release of the Gaia Mission’s third data catalog. Unlike other missions that target specific objects, Gaia is a “simple” reconnaissance mission. … 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

How to photograph the Milky Way?

It can be admired on starry nights where there is very little light pollution. It looks like a Milky Way crossing the sky, hence the name: The Milky Way. But beware, due to its low light, photography requires specific equipment! You will also be interested [EN VIDÉO] The first image of the Milky Way’s central … Read more

The study of galactic bulbs reveals the formation of “waves”

Several observations made thanks to the Great Telescope in the Canary Islands have made it possible to understand the origin of the creation of certain types of galaxies that resemble the Milky Way. Like cities on Earth, their galactic bulges would form in two waves, the first consisting of old stars and the second of … Read more

A supermassive black hole may be hiding in a dwarf galaxy near the Milky Way

Towards the end of the 1960s, there were a few researchers, including Martin Rees, but especially his colleague and countrymanastrophysicist British Donald Lynden-Bell, claimed that the majority of large galaxies must host supermassive black holes in their center. This is a dissertation that has been widely accepted for at least 20 years, although a conclusive … Read more

See what binary systems with black holes in the Milky Way look like

Recently one joint press release from European Southern Observatory (ESO) andEvent Horizon Telescope (EHT) has announced that on May 12, 2022, there will be an online conference at. 15.00 in France, which will report new results and especially about supermassive black hole of The Milky Way. It contains just over DKK 4 million masses solar … 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

Astronomers have just discovered a new secret about the Milky Way

Astronomers have developed a rather advanced knowledge of the galaxies that cover our universe. But ours, the Milky Way, still hides secrets. It has also just unveiled a new one: a ring of metal-rich stars surrounding the galactic bar. You will also be interested [EN VIDÉO] The Milky Way: the simulation of the formation of … Read more
