Scientists Think They’ve Found the Ancient Neutron Star Crash That Showered Our Solar System in Gold

This entry was posted in Science on by .

In a new study published May 1 in the journal Nature, the duo analyzed the remnants of radioactive isotopes, or versions of molecules with different numbers of neutrons, in a very old meteorite. Then, they compared those values with isotope ratios produced by a computer simulation of neutron star mergers ‘ cataclysmic stellar collisions that can cause ripples in the fabric of space-time.

Chinese Astronomers Saw an Exploding Star 2,000 Years Ago. Scientists May Have Just Found the Remains

Scientists think that they’ve stumbled upon the remains of a stellar explosion first observed by Chinese astronomers over 2,000 years ago, according to a new paper.

Novae are explosions that occur on the surface of white dwarf stars sucking up matter from a partner in a binary system. After the blast, they leave behind clouds of gas and dust, forming a nebula. Bright outer space events have been noted by ancient astronomers throughout history, but this nova would be one of the earliest confirmed extrasolar events, the authors write in the paper to be published in the journal Astronomy & Astrophysics.

Scientists in Chile have found a 15,000-year

A team of scientists in Chile say they’ve found a human footprint that dates back more than 15,000 years — the oldest one ever found in the Americas.

The discovery challenges the previous timeline and map of human migration into South America. Most available evidence held that humans did not reach the Patagonia region at the southern tip of South America until 12,000 years ago, Karen Moreno, one of the co-authors of the research, told CNN.

The scientists believe the trace fossil is an impression of the bare right foot of an adult human, Moreno said. The research was published last week in the scientific journal PLOS-ONE.

Scientists in Chile have found a 15,000-year

The footprint was found in 2010 at a paleo-archaeological site in the city of Osorno in the southern part of the country, at the edge of a town home development. But it took years for scientists to confirm the age of the fossil through carbon dating.

Scientists were alerted to the richness of the area after construction workers, digging to build houses, began unearthing treasures hidden below the surface.

A new wave of research has been ongoing there since 1986 and has uncovered the remains of large animals, ranging from mastodons to horses to a paleo-llama, a larger species of llama that is now extinct.
