HER2 is so named because it has a similar structure to human epidermal growth factor receptor, or HER1. Neu is so named because it was derived from a rodent glioblastoma cell line, a type of neural tumor. ErbB-2 was named for its similarity to ErbB (avian erythroblastosis oncogene B), the oncogene later found to code for EGFR.
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
The following dates are approximations. 700 BC: Pythagoras's theorem is discovered by Baudhayana in the Hindu Shulba Sutras in Upanishadic India. [18] However, Indian mathematics, especially North Indian mathematics, generally did not have a tradition of communicating proofs, and it is not fully certain that Baudhayana or Apastamba knew of a proof.
Clayton calculated the first time-dependent models of the s-process in 1961 [15] and of the r-process in 1965, [16] as well as of the burning of silicon into the abundant alpha-particle nuclei and iron-group elements in 1968, [17] [18] and discovered radiogenic chronologies [19] for determining the age of the elements.

January 26 – The Ranger 3 space probe is launched to study the Moon, but later misses it by 22,000 miles.; February 4–5 – During a new moon and total solar eclipse, an extremely rare grand conjunction of the classical planets occurs, including all five of the naked-eye planets plus the Sun and Moon, all within 16° of each another on the ecliptic.
The following outline is provided as an overview and topical guide to space science: Space science – field that encompasses all of the scientific disciplines that involve space exploration and study natural phenomena and physical bodies occurring in outer space, such as space medicine and astrobiology.

February 27 – James Stanley Hey, a British Army research officer, first detects radio waves emitted by the Sun, helping to pioneer radio astronomy. [1]October 3 – The first V-2 rocket is successfully launched from Test Stand VII at Peenemünde, Germany, flying a distance of 147 km and reaching a height of 84.5 km, becoming the first man-made object to reach space.
