While monitoring the distance to Type Ia supernovas, two separate teams found that not only is the universe expanding but that this expansion is also accelerating. Dark energy was introduced as a ...
The research is based on Nobel Prize winner Adam Riess' discovery that the universe's expansion is accelerating due to a mysterious "dark energy" that permeates vast expanses of space between ...
Since the universe is still expanding, with each passing year a galaxy is a bit more distant, and that means its redshift should become slightly larger. In other words, cosmic expansion means that ...
The Vera C. Rubin Observatory is set to revolutionize our understanding of the cosmos by detecting millions of exploding stars — Type Ia supernovae — over the next decade. These brilliant explosions ...
Through the lens of the Hubble and James Webb Space Telescopes, scientists are zeroing in on the Hubble Constant, a vital ...
Scientists challenge the existence of dark energy. They suggest the universe's accelerating expansion is due to uneven gravitational effects on time. This new theory, called the "timescape" model ...
