Such discoveries are often a multi-step, multi-person process. Multiple discovery sometimes occurs when multiple research groups discover the same phenomenon at about the same time, and scientific priority is often disputed. The listings below include some of the most significant people and ideas by date of publication or experiment.
This is a timeline of space exploration which includes notable achievements, first accomplishments and milestones in humanity's exploration of outer space. This timeline generally does not distinguish achievements by a specific country or private company, as it considers humanity as a whole.
Thanks to the James Webb Space Telescope, our view of the universe has exploded, to encompass many more galaxies and phenomenal exoplanet discoveries. The Most Important Discovery of 2022 Is Our ...
This discovery was critical to the formulation of the Watson-Crick Model of DNA structure. Neil Bartlett mixes xenon and platinum hexafluoride leading to the first synthesis of a noble gas compound, xenon hexafluoroplatinate (1962). Robert Burns Woodward announces the total synthesis of Vitamin B-12 by a team he led (1973).
Discovery and exploration of the Solar System is observation, visitation, and increase in knowledge and understanding of Earth's "cosmic neighborhood". [1] This includes the Sun , Earth and the Moon , the major planets Mercury , Venus , Mars , Jupiter , Saturn , Uranus , and Neptune , their satellites , as well as smaller bodies including ...
As the century ended, a permanent human presence in space was being founded with the ongoing construction of the International Space Station. In addition to human spaceflight, uncrewed space probes became a practical and relatively inexpensive form of exploration. The first orbiting space probe, Sputnik 1, was launched by the Soviet Union in ...
While searching an unusual cold spot in space first discovered more than a decade ago, scientists have discovered what they say is the largest known structure in the universe -- a supervoid, ITN ...
