NASA's Roman telescope to unlock 100,000 cosmic explosions in major survey

From dying stars to feeding black holes, the Roman Space Telescope's upcoming survey is set to unlock the secrets of dark energy and the universe's most powerful blasts

Dark energy discovery changed understanding of universe: Nobel laureate

Dark matter pulls the universe and dark energy pushes, both mysteries that endure. And the discovery that a majority of the universe is made up of stuff that makes gravity push rather than pull was a gamechanger, says Nobel laureate Brian Schmidt. The US-born Australian astronomer along with Adam Riess and Saul Perlmutter from the US discovered the stuff, later termed dark energy, in 1998. The three won the Nobel Prize for Physics in 2011. Explaining the significance of their discovery that changed the understanding of how the universe functions, Schmidt told PTI, "Dark energy is really saying (that) there is energy tied to space itself. If we didn't have dark energy, the universe would be curved and the universe wouldn't accelerate -- and that changes how cosmic objects, such as galaxies, looks. It really makes a difference," the astronomer, who was visiting Ashoka University for the Lodha Genius Programme, added. The term dark energy is intentionally similar to dark matter. Dark
