Similar fossils had been found during the 1930s (in Namibia) and the 1940s (in Australia) but these forms were assumed to be of Cambrian age and were therefore considered unremarkable at the time. Originally interpreted as an alga , Charnia was reinterpreted as a sea pen (a group related to the modern soft corals ) from 1966 onwards.
GRB 090423 was a gamma-ray burst (GRB) detected by the Swift Gamma-Ray Burst Mission on April 23, 2009, at 07:55:19 UTC whose afterglow was detected in the infrared and enabled astronomers to determine that its redshift is z = 8.2, making it one of the most distant objects detected at that time with a spectroscopic redshift (GN-z11, discovered ...
The earliest dyed flax fibers have been found in a prehistoric cave in the Republic of Georgia and date back to 36,000. [21] The 25,000-year-old Venus Figurine "Venus of Lespugue", found in southern France in the Pyrenees, depicts a cloth or twisted fiber skirt. Some other Western Europe figurines were adorned with basket hats or caps, belts ...
The Oldest Living Organism Is Over 2 Billion Years Old Scientists have identified the oldest living species on Earth is a deep sea organism that hasn't evolved in more than two billion years.
Some of the latter may be visible in gravitational lensing in looking at deepest images such as the Hubble Ultra-Deep Field (i.e., their brief existence before their turning into supernovae). As with HD 122563 , CS22892-0052 , and CD−38 245 , HD 140283 has an excess of oxygen and the alpha elements relative to iron. [ 1 ]

In cosmology, galaxy filaments are the largest known structures in the universe, consisting of walls of galactic superclusters.These massive, thread-like formations can commonly reach 50 to 80 megaparsecs (160 to 260 megalight-years)—with the largest found to date being the Hercules-Corona Borealis Great Wall at around 3 gigaparsecs (9.8 Gly) in length—and form the boundaries between voids ...
