A gravitational-wave telescope on the Moon could span the gap between Earth-based and space-based observations.
We find examples of fractals everywhere in nature. Tree branches, snowflakes, river deltas, cloud formations, and more. So it's natural…
Using isotope measurements of a supernova remnant, astronomers have calculated the core density of a white dwarf before it exploded.
Cosmologists have been struggling to understand an apparent tension in their measurements of the present-day expansion rate of the universe,…
Cosmology is now stranger to large scale surveys. The discipline prides itself on data collection, and when the data it…
Can waves of gravity be lensed by gravity? A recent study looks for lensed gravitational waves.
Cosmologists love universe simulations. Even models covering hundreds of millions of light years can be useful for understanding fundamental aspects…
Astronomers are struggling to understand the discrepancies when measuring the expansion rate of the universe with different methods, and are…
In the very earliest moments of the big bang, the universe experienced a period of rapid expansion known as inflation.…
