Astronomers have identified a group of small galaxies situated approximately 3 million light-years distant that encompasses the least massive and dimmest galaxy detected so far. This galaxy, labeled as Andromeda XXXV, along with its companions circling around our neighboring galaxy, Andromeda, might alter our perspective cosmic evolution. This is because dwarf galaxies of such a tiny size ought to have been obliterated under the warmer and more crowded circumstances prevalent during those periods. early universe And yet, for some reason, this small galaxy managed to survive without being destroyed. Despite their full functionality, these galaxies are approximately one-millionth the size of our Milky Way galaxy," stated team member and University of Michigan professor Eric Bell. He compared this phenomenon to imagining a completely normal person shrunk down to the size of a single grain of rice. Meet Andromeda XXXV Dwarf galaxies are not unfamiliar to scienti...

The universe could be home to far more supermassive black holes than we realised, according to new research. The researchers propose that numerous such structures remain concealed from our sight—indicating that we may have significantly underestimated the number of these rotating voids in our universe. cosmos . Astronomers from the University of Southampton say that 35% of these galactic giants - some which are billions of times heavier than the sun - have gone undiscovered because they are obscured by thick clouds of gas and dust. This number had previously been estimated to be about 15%. Professor Poshak Gandhi, co-author of the study published in the Astrophysical Journal, said: “Black holes are the most mysterious objects in the universe and are present everywhere - yet we still don’t fully know how they evolve. “We’ve found that many more are lurking in plain sight - hiding behind dust and gas rendering them invisible to normal telescopes. This marks the in...

In outer space, the strong gravity of large bodies exerts an unyielding force over smaller entities. Satellites maintain their paths circling planets. Various celestial bodies like worlds, minor planets, and icy wanderers move around larger suns, with these luminous cores gathering alongside enormous singularities to create vast star systems known as galaxies. Large galaxies, like the Milky Way , draw in smaller galaxies. The celestial vicinity of our solar system extends across 100,000 light-years and includes approximately 100 billion to 400 billion stars . The Milky Way is so big that, over billions of years, its mass has captured numerous dwarf galaxies, which contain no more than a few billion stars, as satellites. However, how many satellite galaxies does the Milky Way possess? The count keeps evolving due to the discovery of fainter galaxies through advanced telescopes and sky surveys. However, let’s begin with those we can readily observe. The two most notable ...
