The Crab Nebula is a supernova remnant located 6,500 light-years from Earth in the constellation Taurus. (constellation Taurus) In astronomical history, the appearance of a powerful light from the Crab Nebula was recorded in 1054 by 11th-century astronomers, and the nebula continues to attract attention and Further study continues until the present.
recently The research team was led by astronomers from Princeton University. in the united states Using the Near Infrared Imager Camera (NIRCam) and the James Webb Space Telescope’s Mid-Infrared Detector (MIRI), they have found answers to the Crab Nebula’s origins. The spatial resolution of the Webb camera allows the precise composition of the ejected material to be determined. Especially the amount of iron and nickel. This may reveal what type of explosion the Crab Nebula was caused by.
The team found that additional features of the inner workings of the Crab Nebula became more prominent. It can be seen in greater detail in the infrared light captured by the Webb camera. Gases are released from charged particles, such as electrons, moving around magnetic field lines at relativistic speeds. apparent radiation This causes the material to appear cloudy and cloudy over much of the Crab Nebula’s interior. It was also found that the magnetic field structure of pulsars Neutron stars (neutron stars that spin at high speeds and emit radio waves) sculpt and shape the nebula.
