An artist’s concept of a “hot Jupiter” extrasolar planet. Credit: NASA/JPL-Caltech Astronomers discover a new way of determining the relative age of exoplanets and prove…
This is an illustration of a close-up look at a black hole drifting through our Milky Way galaxy. The black hole is the crushed remnant…
An artist’s impression of two black holes about to collide and merge. Gravitational waves are ripples in the curvature of spacetime caused by accelerated masses…
An illustrated view of a black widow pulsar and its stellar companion. The pulsar’s gamma-ray emissions (magenta) strongly heat the facing side of the star…
Artist’s illustration of a black hole. Gravitational microlensing turns up black holeA black hole is a place in space where the pull of gravity is…
Astronomers have finally resolved the conflict between the internal structure of the Sun as determined from solar oscillations and the structure derived from the fundamental…
Astrophysicists Create “Time Machine” Simulations To Observe the Lifecycle of Ancestor Galaxy Cities
Scientists create “time machine” simulations studying the lifecycle of ancestor galaxy cities. Many processes in astrophysics take a very long time, making their evolution tricky…
The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity published in 1905 and general relativity published in 1915. Special relativity…
