The biggest known galaxy, first described in a 1990 study from the journalScience, is IC 1101, which stretches as wide as 4 million light-years across,according to NASA. Galaxies are often bound to each other gravitationally in groups that are calledgalaxy clusters. (The Milky Way, for examp...

Yet even though the law of gravity is universal, and the same on all scales, the Universe doesn’t form star clusters, galaxies, and galaxy clusters all at once. Instead, structure formation in the Universe is hierarchical: with the smallest-scale structures like stars and star clusters formin...
How life on Earth began remains an unexplained scientific problem. This problem is nuanced in its practical details and the way attempted explanations feedback with questions and developments in other areas of science, including astronomy, biology, and p
