More Evidence That the Blueprint For Life Started in Space

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 in meteorite samples, adding evidence to the theory that life began in space. The study, led by associate professor Yasuhiro Oba of Japan’s Hokkaido University, has revealed the elusive cytosine and thymine within …

Merger of Two Black Holes Predicted

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 happen in 100 days or sometime in the next three years. Each of the black holes is estimated to be 70 times the size of our sun, and they are located in a …

A New Type of Star Likely Discovered

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 disappeared before reappearing and brightening again, and assumed it was a supernova (a dying star) or a neutron star (an already-dead star) but found that it’s neither. In fact, it could be a …
