Matter swirling around supermassive black holes creates bursts of light that "echo" in nearby dust clouds. These traveling signals could serve as a new cosmic yardstick.

Two large international collaborations of astronomers joined forces to look for light from some of the most cataclysmic events – the collisions of a neutron star and black hole. They did not find it this time, but the scientific journey has provided important insights on how to better hunt for...

The Nancy Grace Roman Space Telescope’s primary mirror, which will collect and focus light from cosmic objects near and far, has been completed. Using this mirror, Roman will capture stunning space vistas with a field of view 100 times greater than Hubble images.

New simulations show that NASA’s Nancy Grace Roman Space Telescope will be able to reveal myriad rogue planets – freely floating bodies that drift through our galaxy untethered to a star.

On August 16, the Zwicky Transient Facility (ZTF), a robotic survey camera located at Palomar Observatory near San Diego, spotted an asteroid that had, just hours earlier, traveled only 1,830 miles (2,950 kilometers) above Earth's surface. Designated 2020 QG, it is the closest known asteroid to...

For just the second time ever, astrophysicists have spotted a spectacular flash of ultraviolet (UV) light accompanying a white dwarf explosion. An extremely rare type of supernova, the event is poised to offer insights into several long-standing mysteries, including what causes white dwarfs to...

Data from NASA's NEOWISE mission, managed by the agency's Jet Propulsion Laboratory, fuels the search for these not-quite-planets-but-not-quite-stars. With the help of citizen scientists, astronomers have discovered two highly unusual brown dwarfs, balls of gas that are not massive enough to...

A comet visiting from the most distant parts of our solar system is putting on a spectacular nighttime display. Named Comet C/2020 F3 NEOWISE, the comet made its once-in-our-lifetimes close approach to the Sun on July 3, 2020, and will cross outside Earth's orbit on its way back to the outer...

When two black holes spiral around each other and ultimately collide, they send out ripples in space and time called gravitational waves. Because black holes do not give off light, these events are not expected to shine with any light waves, or electromagnetic radiation. But some theorists have...
