And Universal material in a form Question mark He stole the limelight in a recent film NASA’s James Webb Space TelescopePosted on July 26.
The original film featured two young stars Herbig-Harrow 46/47 calls Well known and often observed by astronomers. They were discovered in the Vela galaxy, 1,470 light-years away. milky way. These stars are relatively young and still forming. I mean, technically “not yet born”The moment they begin to glow from their own nuclear fusion.
James Webb Telescope
Both stars have been observed and studied by space and ground-based telescopes 1950sBut thanks to the highly sensitive James Webb telescope, we were able to get a much more detailed image with much higher resolution.
The Webb telescope offers insight into the origins of our universe, but the appearance of this mysterious object in the background of the photo leaves more questions than answers. This is The cosmic question mark For this reason, not closely observed or studied, Scientists are not sure about its origin or its composition.
The amazing sensitivity of the telescope was able to capture it Red question mark Below the image. “This could be a merger of two galaxies, probably billions of light-years apart, much farther away than Herbig-Harrow 46/47,” he said. Christopher BrittEducation and Outreach Scientist in the Office of Public Affairs at the Space Telescope Science Institute, which manages the science operations of the Webb Telescope.
“That’s something Often seen, as galaxies grow and evolve over cosmic time, they sometimes collide with their nearest neighbors. When that happens, they can be distorted in all sorts of different ways, a Question markBrit commented.
Weird event?
It is probably the This item is being viewed for the first time, according to astronomers, the question mark-shaped merger of galaxies has happened before. Two merging galaxies were captured Hubble Space Telescope In 2008, it also looks like a question mark, but in an inverted version – rotated 90 degrees.
Britt cautions that calculating distance based solely on image colors can be tricky. He The question mark is red That means It is far away (Light waves are stretched as they travel through an expanding universe, moving towards redder wavelengths) or whichever is closer and obscured by dust near the object.
