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.
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 ...
The planet has a mass less than 0.3 Jupiter masses (90 Earth masses) and a radius nearly equal to that of Jupiter, just 4% smaller, or the same as 10.7 Earth radii. [1] It is still enshrouded in an hydrogen envelope, and will shed its outer layers during its evolution, [2] becoming either a sub-Neptune, super-Earth or a sub-Saturn.
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 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.

Designators are assigned to objects by the United States Space Command along with satellite catalog numbers as they are discovered in space. [1] The United Nations Office for Outer Space Affairs (UNOOSA) and the National Space Science Data Center (NSSDC), part of NASA, maintain two catalogs that provide additional information on the launchers and payloads associated with the designators.
January 26 – The Hale Telescope at Palomar Observatory in California, the largest aperture optical telescope in the world for 28 years, sees first light.; June 14 – Albert II, a rhesus monkey, becomes the first mammal in space, in a U.S.-launched V-2 rocket, reaching an altitude of 83 miles (134 km) but dying on impact after a parachute failure.
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.
