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 ...
A stimulus to the development of the theory of nucleosynthesis was the discovery of variations in the abundances of elements found in the universe. The need for a physical description was already inspired by the relative abundances of the chemical elements in the solar system.
In 1992, the first evidence of a planetary system other than our own was discovered, orbiting the pulsar PSR B1257+12. Three years later, 51 Pegasi b, the first extrasolar planet around a Sunlike star, was discovered. NASA announced in March 2022 that the number of discovered exoplanets reached 5,000, of several types and sizes. [45]
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.
On 31 October 2013, calibrated IRIS data and images were released on the project website. [10] An open-access article describing the satellite and initial data was published in the journal Solar Physics. [11] Data collected from the IRIS spacecraft has shown that the interface region of the Sun is significantly more complex than previously ...
Launch of Mariner 1 in 1962. The Mariner program was conducted by the American space agency NASA to explore other planets.Between 1962 and late 1973, NASA's Jet Propulsion Laboratory (JPL) designed and built 10 robotic interplanetary probes named Mariner to explore the inner Solar System – visiting the planets Venus, Mars and Mercury for the first time, and returning to Venus and Mars for ...
It is the fourth-closest star or (sub-) brown dwarf system to the Sun and was discovered by Kevin Luhman in 2013 using data from the Wide-field Infrared Survey Explorer (WISE). It is the coldest brown dwarf found in interstellar space, having a temperature of about 285 K (12 °C; 53 °F). [ 4 ]
