Due to advances in technology, scientists have been keeping an eye out for signs of alien megastructures. One scientist hypothesizes that, if such a megastructure exists, it would be around a pulsar instead of a star.
Researchers have announced the third detection of gravitational waves—ripples in the fabric of space and time.
The latest response to the Fermi paradox.
And there are indications that groundwater persisted for far longer.
Brazilian physicists have made a significant observation that expands our understanding of an unusual phenomenon called blackbody force. This new research could help us refine our models of how planets and stars are formed.
Talk about rocking the cradle. Sharp new images have identified a throng of newborn stars as the source of a fast radio burst. The discovery strengthens the idea that these brief pulses of radio waves arise from newly formed neutron stars, super-dense objects just 20 kilometres across.
Some have cast doubt about the existence of black hole event horizons from which nothing, not even light, can escape the gravitational pull.
Three billion years ago, in a third of a second, two black holes crashed into each other and merged into a single entity, converting two solar masses into energy that shook the fabric of spacetime, sending gravitational ripples across the universe that were detected on Earth last January, researchers announced Thursday.
Findings suggest Red Planet had ocean, active hydrologic cycle
This gas giant gives “hot Jupiter” a whole new meaning.
