On 15 August 1977 at 10:16PM EST, Ohio State University’s Big Ear radio telescope scanned the Sagittarius constellation and detected a signal that was 20 times stronger than average, background emissions. When …
In a new study, scientists have found the remaining two of the five informational units—known as nucleobases (adenine, guanine, cytosine, thymine and uracil)—of DNA and RNA that were still to be detected …
Astronomers are watching two highly eccentric black holes in a “gravitational tango” that might result in them merging—an event that astronomers have predicted but have never witnessed before. The cosmic incident could …
Located about 4,000 light-years from the sun, a “mysterious, flickering object” that emits huge amounts of energy every few hours has been discovered. Astronomers watched as the object—named GLEAM-X J162759.5-523504.3—brightened, dimmed and …
Despite being only 10% into its five-year mission, the Dark Energy Spectroscopic Instrument (known as DESI) has already mapped more than 7.5 million galaxies as it looks up to 10 billion light-years …
Crochet-covered streets, "water world" planets, scent-recognizing devices and more from around the web
The search for exoplanets has traditionally centered on those similar to Earth (of a relatively proportionate size and mass with comparable temperatures and atmospheric compositions) but scientists are now “rethinking the kinds …
Most space enthusiasts are aware that nothing can escape the tremendous gravitational pull of a black hole but, for the first time ever, scientists have detected light coming from behind a black …
With global camaraderie, amateur astronomers and citizen scientists track the cosmos using smart technology
As part of an ambitious new survey of the cosmos, the Dark Energy Spectroscopic Instrument (DESI) will analyze light collected by the ultra-powerful Mayall telescope at Kitt Peak National Observatory. “DESI will record …
