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.
At the later stages of radiation- and matter-domination, these fluctuations re-entered the horizon, and thus set the initial conditions for structure formation. The statistical properties of the primordial fluctuations can be inferred from observations of anisotropies in the cosmic microwave background and from measurements of the distribution ...
The L.A. Times misreported that a DNA mutation from space exposure could yield a poisonous fruit. While incorrect, the report served to raise awareness of the experiment and generate discussion. [17] Space seeds germinated sooner and grew faster than the control seeds. Space seeds were more porous than terrestrial seeds. [18]
“Asteroids provide a time capsule into our home planet’s history, and Bennu’s samples are pivotal in our understanding of what ingredients in our solar system existed before life started on ...
An animated example to show the utility of a spaced seed. First, an attempt to identify a local candidate match without a space seed is made (unsuccessfully), before attempting the same task with a simple spaced seed, where a hit is found successfully. Green indicates a matching base position. See here for more details.

Structure formation began some time after recombination, when the early universe cooled enough from expansion to allow the formation of stable hydrogen and helium atoms. [7]: 6 At this point the cosmic microwave background(CMB) is emitted; many careful measurements of the CMB provide key information about the initial state of the universe before structure formation.
This is a list of the largest cosmic structures so far discovered. The unit of measurement used is the light-year (distance traveled by light in one Julian year ; approximately 9.46 trillion kilometres ).
