The James Webb Space Telescope has been in space for about two years, constantly providing us with stunning images of various objects. And also from very distant corners of the universe. This time we have the opportunity to see something closer to us. this A protostar located in the Milky Way Galaxy Over time, he will turn into an ordinary star.
The facility is called Herbig-Haro 211 (HH 211) and is located inAbout a thousand light-years away in the constellation Perseus. A protostar captured by the James Webb Space Telescope can be seen in all its glory. We can see that it is absorbing dust and gas, which will allow it to grow over time. in the meantime It expels huge amounts of material in the form of two oppositely directed jetswhich sounds really exceptional.
The protostar captured is likely in a binary system, which is abundant and very common in the Milky Way. With time It will turn into a star similar to our sun. It currently accounts for what the solar system’s central body is only a few tens of thousands of years old and constitutes only 8 percent. Its current mass.
Object HH 211 is very special to astronomers. This is due to the fact that it is one of the closest protostars known to contain jets of ejected material. Therefore, it is ideal for making more detailed observations thanks to the James Webb Space Telescope, mainly due to the infrared imaging capabilities of the NIRSpec (near infrared spectrometer) instrument. Thanks to this, it is able to “penetrate” clouds of dust and gas.
James Webb Space Telescope thanks to specialized instruments It made it possible to study the chemical composition of the protostar. Research has shown that jets of young stars are much slower and richer in molecules such as carbon monoxide, silicon oxide and molecular hydrogen than older objects of this type. This is due to processes related to shock waves surrounding protostars. They are not yet strong enough to tear apart the molecules that make up the jets into single atoms.
It is worth noting that the James Webb Space Telescope was designed primarily to observe the distant corners of the universe, but part of its research time was devoted to searching the solar system. Thanks to this, we obtained amazing images of planets such as Jupiter, Saturn and Neptune, which showed us new faces.
Echo Richards embodies a personality that is a delightful contradiction: a humble musicaholic who never brags about her expansive knowledge of both classic and contemporary tunes. Infuriatingly modest, one would never know from a mere conversation how deeply entrenched she is in the world of music. This passion seamlessly translates into her problem-solving skills, with Echo often drawing inspiration from melodies and rhythms. A voracious reader, she dives deep into literature, using stories to influence her own hardcore writing. Her spirited advocacy for alcohol isn’t about mere indulgence, but about celebrating life’s poignant moments.
