Spectacular Ultraviolet Flash May Finally Explain How White Dwarfs Explode

ZTF • News Release • July 23rd, 2020

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...

Two Bizarre Brown Dwarfs Found With Citizen Scientists' Help

Near-Earth Object Wide-field Infrared Survey Explorer • Project News • July 10th, 2020

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...

Comet NEOWISE Sizzles as It Slides by the Sun, Providing a Treat for Observers

Near-Earth Object Wide-field Infrared Survey Explorer • Project News • July 8th, 2020

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...

Black Hole Collision May Have Exploded with Light

ZTF • News Release • June 25th, 2020

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...

Public Data Release 3

ZTF • News Release • June 24th, 2020

The Zwicky Transient Facility (ZTF) and IPAC at the California Institute of Technology announce the third ZTF Public Data Release. ZTF is an optical time-domain survey covering the northern sky visible from Palomar Observatory.

Black Hole Collision May Have Exploded with Light

ZTF • News Release • June 15th, 2020

With the help of Caltech's Zwicky Transient Facility (ZTF), funded by the National Science Foundation (NSF) and located at Palomar Observatory near San Diego, the scientists have spotted what might be a flare of light from a pair of coalescing black holes. The black hole merger was...

Astronomers' Discovery Sheds New Light On Famous Einstein Ring

Keck Observatory Archive • Project News • June 1st, 2020

Determined to find a needle in a cosmic haystack, a pair of astronomers time traveled through archives of old data from W. M. Keck Observatory on Mauankea in Hawaii and old X-ray data from NASA’s Chandra X-ray Observatory to unlock a mystery surrounding a bright, lensed, heavily obscured quasar.

NASA Telescope Named For ‘Mother of Hubble’ Nancy Grace Roman

Nancy Grace Roman Space Telescope • Project News • May 20th, 2020

NASA is naming its next-generation space telescope currently under development, the Wide Field Infrared Survey Telescope (WFIRST), in honor of Nancy Grace Roman, NASA’s first chief astronomer, who paved the way for space telescopes focused on the broader universe.

A Tale of Two Telescopes: WFIRST and Hubble

Nancy Grace Roman Space Telescope • Project News • April 20th, 2020

NASA’s Wide Field Infrared Survey Telescope (WFIRST), planned for launch in the mid-2020s, will create enormous cosmic panoramas. Using them, astronomers will explore everything from our solar system to the edge of the observable universe, including planets throughout our galaxy and the nature of...
