“Every good thing comes to an end.” This saying is valid both in the universe and on Earth. We realize that stars, like everything else, must die. When the fuel supply for nuclear fusion in their cores is exhausted, stars of all sizes collapse under their own gravity and die to form a dense cosmic… Read More »
Scientists have discovered that the Milky Way’s diffuse outer halo is devoid of any unusually large black holes. The discovery could spell bad news for theories that suggest dark matter, the universe’s most mysterious “stuff,” is composed of primordial black holes that formed in the early moments after the Big Bang. Dark matter is confusing… Read More »

The strange behavior of the massive merging galaxy cluster could be explained by the collision of dark matter, the universe’s most mysterious substance, with itself. However, the currently most favored model of cosmology is the cold dark matter (CDM) model, which posits that dark matter, which is virtually invisible because it does not interact with… Read More »
The search for tiny black holes, missing from the Big Bang, may be about to heat up. Just as the trail of such tiny black holes appears to have cooled, an international team of scientists has found clues in quantum physics that could reopen the case. One reason why the hunt for these so-called primordial… Read More »
On Thursday, May 23, the European Space Agency (ESA) and collaborators released a series of five images created by the revolutionary space telescope Euclid. The Euclid consortium previously published five images from the space telescope on November 7, 2023. Euclid has been labeled Europe’s “dark universe detective” because its wide field of view allows it… Read More »
At first glance, the image doesn’t look like much: a few patches of bright yellow stars among fainter white stars. There is a spot in the middle that looks like a collection of stars. But zooming in reveals a completely different story. This blob is not stars at all, but dozens upon dozens of galaxies.… Read More »
A mind-boggling number of glowing galaxies, a purple and orange chamber of stars and a spiral galaxy that resembles the Milky Way: new images emerged from Europe’s Euclid space telescope on Thursday. HE second set of pictures It has been published by the European Space Agency since Euclid launched its first mission last year to… Read More »
Europe’s Euclid telescope has sent back the largest images of the universe ever taken from space, as part of its quest to unlock the secrets of the universe. Five images released by the European Space Agency (ESA) offer an exciting glimpse into the distant cosmic past, capturing vast new areas of the sky in unprecedented… Read More »
