From the first disks of planetary debris discovered in 1983Infrared astronomical satellite (IRAS) around four Formalhat and For protoplanetary discs examined with alma by observations And Astronomy And helped to ensure that the phenomenon of planetary formation with millimeter force occurs very frequently And according to the methods, in broad outline, created in the cosmological models of the solar system.Vega,
However, we still have a lot to learn because planetary scientists do not fully understand the exact chemical processes involved in the formation of planets. They also want to know if there is anything special about the way our own planets formed around us For more information.. Of course, we already have indications with the tools developed by Nuspier, but we are not far from sending a study to a nearby planetary system, but would like to know more.
In this short film, we tell the story of the interstellar comet 2I / Borisov. For us Earthlings, it’s a story that begins when we first see it at the end of August 2019, but it started ten or hundreds of millions of years ago, or more … because we do not know. Yet the age of this material came from somewhere else. © Future
Infrared radiation to read a galaxy’s memory
However, Martin Gardiner announced this in a press release It now offers us an unprecedented opportunity to study the chemical composition of these galaxies and to learn more about their properties: where they came from, how they formed, and what they can tell us about the conditions under which they formed. ⁇The primary analyst of a project Web target for opportunity : ” Sensitivity and power
Clear to thisFrom Goddard Space Aviation Center From NASA in Greenfield, Maryland: ” The ability to read one of them and discover its composition – to look closely at objects from another planetary system – is truly incredible. “, And he and his team are preparing for an infrared study with the Web in the future. Hyperbolic in the solar system, and they only visit once.
2I / Borisov looked like a comet, but not 1I / ‘Oumuamua. This suggests that we are about to make spectacular discoveries about the diversity of planetary systems. Martin Gardiner and his colleagues want to know for sure, for which they will use two James-Web tools, NIRSpec and MIRI.
Will be used to analyze the chemical composition of NIRSpec, according to a NASA press releaseIt can emit these galaxies closer to the sun, which can highlight its spectral signature Specific substances such as water and methanol The The And methane. MIRI (Central Infrared Instrument)For its part, it gives information about the thermal processes associated with the particles Such as dust grains and pebbles.
