Many seem to think that the next total solar eclipse in North America after April 8 is in 2044. There’s actually one coming much sooner, in Alaska.
An international team of scientists led by astronomers from Tartu Observatory of the University of Tartu has discovered many superclusters in the universe, with the most prominent among them named the ‘Einasto Supercluster’ in honor of Prof. Jaan Einasto, a pioneering figure in the field, who celebrated his 95th birthday on 23 February.
Superclusters, akin to vast metropolitan cities in space, represent the largest and most massive collections and clusters of galaxies in the universe. The team’s findings not only expanded our understanding of these vast structures but also paved the path to shed light on the ongoing mystery of their formation.
In their study, the scientists determined that the typical mass of superclusters is an astonishing 6 million times billion that of the sun, with an average size of 200 million light-years. To put this into perspective, these superclusters are approximately 2,000 times larger than our own Milky Way galaxy.
One day humanity may settle countless worlds, but could any nation hope to govern multiple planets or even star systems?

Gauging whether or not we dwell inside someone else’s computer may come down to advanced AI research—or measurements at the frontiers of cosmology.
The only people who absolutely disagree are, well, scientists. They need to get over themselves and join the fun.

In the 1940s, computer pioneer Konrad Zuse began to speculate that the universe might be nothing but a giant computer continually executing formal rules to compute its own evolution. He published the first paper on this radical idea in 1967, and since then it has provoked an ever-increasing response from popular culture (the film The Matrix, for example, owes a great deal to Zuse’s theories) and hard science alike.
Scientists say that long genes — which are more susceptible to DNA damage — might be a main cause of the body’s aging and could play a role in. the development of diseases like Alzheimer’s.
