Data from the Hubble Space Telescope shows that astronomers have discovered that the interstellar comet-21/Borisov may be the most primitive galactic object when viewed from outside the solar system. It is speculated that this comet was caused by a red dwarf star. It became the first confirmed interstellar object last year and it passed through the Earth’s solar system. According to Hubble’s Cosmic Origin Spectrometer (COS) observations, it was discovered that the first confirmed comet that entered our solar system was composed of carbon monoxide, and was related to the comet of the Earth’s solar system, the Atacama large millimeter / sub-micrometer of the National Radio Astronomy Observatory of NASA Compared with millimeters, it has different characteristics. Find the array (ALMA).
Known as Oumaumua in Hawaiian, translated as “scout”
Observe the light polarization
In a study published on March 30 in the journals Nature Communications and Natural Astronomy, the scientists said: “2I/Borisov has two new ways different from known comets.” According to the European Southern Observatory According to the analysis of large telescopes, 2I/Borisov’s coma was wrapped in a mass of gas, which scatters light like dust. These light wave emissions fluctuate in space from the gaseous core and cause polarization. In fact, the researchers found that 2I/Borisov’s coma was very polarized. In addition, scientists discovered that the dust in 2I/Borisov’s coma was composed of dense pebbles with a width of about 0.08 inches (2 mm). According to NASA’s release, “2I/Borisov” is approximately 9 football fields in length, which makes it smaller than other comets in the solar system.
