One of the first disks of planetary debris discovered in 1983 byInfrared astronomical satellite (IRAS) around the four and Fomalhaut and To the protoplanetary discs studied with ALMA through observations And the astronomy and millimeter strongly in confirming that the phenomenon of planet formation was very frequent in and according to the methods which, in general, were those developed in the cosmogony models of the solar system.vega,
However, we still have a lot to learn, not least because planetary scientists don’t fully understand the exact chemical processes involved in planet formation. They also want to know if there is anything special about the way our planets were formed around our planet for more information.. Of course, we already have indications with the instruments developed by noosphere, but we would like to know more, despite the fact that we are not very far from being able to send a probe to a nearby planetary system, such as the
In this short film, we tell you the story of the interstellar comet 2I / Borisov. A story that begins, for us Earthlings, at the end of August 2019 when we first looked at it, but it started tens or hundreds of millions of years ago, or even more… because we don’t yet know the age of this being from somewhere else. © Futura
Infrared to read interstellar memory
However, this is what Martin Cordiner just announced in a press release from It now offers us an unprecedented opportunity to study the chemical composition of these interstellar bodies and learn more about their nature: where they come from, how they were made, and what they can tell us about the conditions in their parent systems. »Principal Investigator of the program Webb’s goal of opportunity : ” sensitivity and strength
Obviously for thisThe Goddard Space Flight Center From NASA in Greenbelt, Maryland: “ Being able to study one of them and discover its composition – to see material from another planetary system up close – is truly incredible. ”, and he and his team are preparing to study in the infrared using Webb in the near future several interstellar objects navigating according to My cut in the solar system, and they’ll only visit it once.
2I/Borisov looks a lot like a comet, but 1I/’Oumuamua wasn’t like that at all. This indicates that we are on the verge of making fascinating discoveries about the diversity of planetary systems. Martin Cordner and his colleagues want to know this for sure and for this they will use two James Webb devices operating in series in the near and mid-infrared range, the NIRSpec and MIRI.
According to a NASA press release, NIRSpec will be used to analyze the chemical composition ofThese can be emitted by interstellar objects close to the Sun, to be able to highlight the spectral signature of specific substances such as water and methanol, The The and methane. Mary (medium infrared instrument)on the other hand, would rather provide information on thermal processes associated with particles such as grains of dust and even gravel.
