This is a celestial body more than 9000 light years away in “Taurus”「IRAS 05506+2414」in. it cannot be captured by the human eyeinfrared wavelength(1.1 to 1.67 μm), so the color of the imageColored by infrared wavelength(four colours: blue, green, orange and red).

According to the European Space Agency (ESA), which released the image, IRAS 05506+2414A dense cloud of gas and dust surrounds a bright young star. In a typical young star, some of the material that flows in from the disc is made of gas and dust around the starEjects in both directions like a thin jetHowever, with IRAS 05506+2414, the situation is different.Material thrown out in a fan at a wide anglebut,Spreads at speeds of up to 350 km/sIt is called.

The explosive phenomenon in IRAS 05506+2414 isCollapse of a young massive binary star systemIt seems that it could have been caused by A similar phenomenon is“The Orion Nebula (M42)”Nebula near center“Orion KL”IRAS 05506+2414 may be the second example. According to ESA, when determining the velocity of ejected material and measuring the distance from Earth to IRAS 05506+2414,“Hubble” Space Telescope.oh“Wide field camera 3 (WFC3)”it is said to have been used.

The top image was created based on an image acquired using the Hubble Space Telescope’s WFC3 (using four types of infrared filters), and was released by ESA as the Hubble Space Telescope image of the week in September 2022. Published on the 19th.
