On August 31, foreign media reported that Hubble Space Telescope recently took a gorgeous photo in space. The celestial body in the photo ejected a beam of blue gas, forming with the surrounding dark space. The strong brightness contrast, like the " lightsaber" that often appears in film and television works, makes this photo show a different kind of color beauty.
According to reports, the celestial body jetting gas in the photo is named after astronomers George Herbig and Guillermo Haro and code-named “HH111” Herbig-Haro Object (Herbig-Haro Object), Astronomers believe that this celestial body can help us "see the process experienced by the primordial sun 4.6 billion years ago." The Herbig-Harrow celestial body is 1,360 light-years away from the earth, and its jet velocity is 300 to 600 km/s, and the jet length is about 2.6 light years. It is estimated that the weight of the Herbig-Harrow celestial body's eruption is about 20 times the weight of the earth, and the temperature is as high as 10,000 degrees Celsius.
For this photo, the European Space Agency (ESA) called it a "relatively rare celestial phenomenon" in its statement on Monday. ESA explained: “Newly formed stars are usually very active, and in some cases they will emit very narrow but very fast jets of ionized gas. Such jets of gas are usually very high in temperature, leading to jets of ionized gas. The material molecules or atoms in the stream generally lose their bondage to electrons, so this jet gas usually contains powerful electricity, making it look unusually radiant."
Another media comment said that usually Herbig-Harrow celestial bodies They can only exist for a few thousand years, so they are very rare. Since the first Herbig-Harrow celestial body was observed in the 19th century, astronomers have observed that there are only more than 1,000 similar celestial bodies, and astronomers have estimated that there are only 150,000 similar celestial bodies in the entire Milky Way . The original scarcity of the celestial body determines its rarity. This time, the Hubble Telescope even photographed the celestial body jetting gas jets, raising the rarity to another level.
