A lucky alignment of galaxies allowed researchers to identify the most powerful and distant "space laser" ever found.
For the first time, astronomers have captured the brilliance of a superluminous supernova via gravitational lensing.
“Well, that’s not supposed to happen.”
Astronomers spotted the ultramassive black hole inside the Cosmic Horseshoe, an equally gargantuan galaxy so powerful that it bends light from distant galaxies.
The structure is nearly 600 million light-years from Earth and is an early display of the nascent dark matter telescope's power.
The cutting-edge observatory is charged with seeing some of the earliest visible light, and the recent image achieves a new milestone in stellar astronomy.
A compound lens forged by two galaxies is helping astronomers get a bead on the Hubble Constant and dark energy.
A gravitational lens tripled the event in the night sky and helped astronomers measure the rate at which the universe is expanding.
Gravitational lenses bend and focus light from the more distant cosmos, offering astronomers a cheat code for chronicling the history of the universe.
