Scientists have analyzed the first batch of data from the Dark Energy Spectroscopic Instrument's quest to map the universe and unravel the mysteries of dark energy.
Potential signs of the rainbow-like "glory effect" have been detected on a planet outside our solar system. Glory are colorful concentric rings of light that occur only under peculiar conditions.
With 5,000 tiny robots in a mountaintop telescope, researchers can look 11 billion years into the past. The light from far-flung objects in space is just now reaching the Dark Energy Spectroscopic Instrument (DESI), enabling ...
A team of astronomers has used NASA's James Webb Space Telescope to survey the starburst galaxy Messier 82 (M82). Located 12 million light-years away in the constellation Ursa Major, this galaxy is relatively compact in size ...
Our star, the sun, on occasion joins forces with the moon to offer us Earthlings a spectacular solar eclipse—like the one that will be visible to parts of the United States, Mexico, and Canada on April 8.
This image from the NASA/ESA Hubble Space Telescope shows a globular cluster called NGC 1651. Like another recent globular cluster image, NGC 1651 is about 162,000 light-years away in the largest and brightest of the Milky ...
In the largest and one of the most ambitious Hubble Space Telescope programs ever executed, a team of scientists and engineers collected information on almost 500 stars over a three-year period. This effort offers new insights ...
Planets form in disks of dust and gas called protoplanetary disks that whirl around a central protostar during its final assembly. Although several dozens of such disks have been imaged, just two planets have been caught ...
Accounts of supernovae—exploding stars—go back thousands of years, and while we know today these events create the building blocks of life itself, there are still unanswered questions about the conditions that cause a ...
A new image from the Event Horizon Telescope (EHT) collaboration—which includes scientists from the Center for Astrophysics | Harvard & Smithsonian (CfA)— has uncovered strong and organized magnetic fields spiraling from ...
