On April 23, 1992, a scientific team led by astrophysicist George Smoot announced that it had found the primordial "seeds" from which the universe has grown. They analyzed data gathered by NASA's Cosmic Background Explorer satellite and discovered the oldest known objects in the universe—so called "wrinkles" in time—thus finding a long-anticipated missing piece in the Big Bang model.
The following is a list of the world's oldest surviving physical documents. Each entry is the most ancient of each language or civilization. For example, the Narmer Palette may be the most ancient from Egypt, but there are many other surviving written documents from Egypt later than the Narmer Palette but still more ancient than the Missal of Silos.
1924 – Celanese Corporation produces the first acetate fiber. 1928 – International Bureau of Standardization of Man Made Fibers founded. [24] 1939 – US passes Wool Products Labeling Act, requiring truthful labeling of wool products according to origin. [25] 1940 – Spectrophotometer invented, with impact on commercial textile dye processes.
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 ...

Here's how faint dwarf galaxies, revealed by JWST, sparked the reionization epoch and ended the universe's dark ages with their powerful radiation. Astronomers Found the Ancient Light Source That ...
NASA astronauts who visited the Moon during the Apollo 14 mission hauled back a whole bunch of material from its surface. At the time, they believed they were bringing Moon rocks and dust so that ...
The earliest evidence of humans using fibers is the discovery of wool and dyed flax fibers found in a prehistoric cave in the Republic of Georgia that date back to 36,000 BP. [5] [6] Natural fibers can be used for high-tech applications, such as composite parts for automobiles and medical supplies.
