ERBB is abbreviated from erythroblastic oncogene B, a gene originally isolated from the avian genome. The human protein is also frequently referred to as HER2 (human epidermal growth factor receptor 2) or CD340 (cluster of differentiation 340). [5] [6] [7] HER2 is a member of the human epidermal growth factor receptor (HER/EGFR/ERBB) family ...
The object itself was detected in ESO images dating back to 1980, but its identification as a quasar occurred only several decades later. [2]An automated analysis of 2022 data from the European Space Agency's Gaia satellite did not confirm J0529-4351 as too bright to be a quasar, and suggested it was a 16th magnitude star with a 99.98% probability.
The International Designator, also known as COSPAR ID, is an international identifier assigned to artificial objects in space. [1] It consists of the launch year, a three-digit incrementing launch number of that year [n 1] and up to a three-letter code representing the sequential identifier of a piece in a launch.
The Red Square Nebula is a celestial object located in the area of the sky occupied by star MWC 922 in the constellation Serpens.The first images of this bipolar nebula, taken using the Palomar Observatory Hale Telescope in California, were released in April 2007.
For example, the vibrational lines of polycyclic aromatic hydrocarbons (PAHs) were identified in 1984, [6] showing the class of molecules is very common in space, [7] but it took until 2021 to identify any specific PAHs through their rotational lines. [8] [9] The carbon star CW Leonis. The visible shells of circumstellar material were ejected ...
Sputnik 1: 4 October 1957 First Earth orbiter [1] [2] Sputnik 2: 3 November 1957 Earth orbiter, first animal in orbit, a dog named Laika [2] [3] [4] Explorer 1: 1 February 1958 Earth orbiter; discovered Van Allen radiation belts [5] Vanguard 1: 17 March 1958 Earth orbiter; oldest spacecraft still in Earth orbit [6] Luna 1: 2 January 1959
c. 750 BCE – During the reign of Nabonassar (747–733 BC), the systematic records of ominous phenomena in Babylonian astronomical diaries that began at this time allowed for the discovery of a repeating 18-year cycle of lunar eclipses. [6] 776 BCE – Chinese make the earliest reliable record of a solar eclipse. [7] [failed verification]
The Materials International Space Station Experiment (MISSE) is a series of experiments mounted externally on the International Space Station (ISS) that investigates the effects of long-term exposure of materials to the harsh space environment. The MISSE project evaluates the performance, stability, and long-term survivability of materials and ...
