Crab Nebula (2024)

Colorful nebula in space with a white haze throughout that is more concentrated in the center with a rippling effect. Colorful gas filaments appear to splash outward from the nebula center, colored yellow, magenta, and blue. A faint black border with right angles at the corners of the images show where the telescope’s field of view stopsdotted line with right angles shows the borders of the telescope’s image. Small white stars dot the background.

NASA’s Hubble Space Telescope captured the intricate detail of the Crab Nebula with its Wide Field Camera 3. The colors in the image trace Hubble’s detection of oxygen and sulfur gases in the nebula at varying densities and energies. The blue areas are the hottest and lowest density. While there is not a lot of green in the image, showing dense neutral oxygen, there is quite a lot of yellow, which appears where green and the red of energized sulfur are near to each other and similarly bright.

The white haze in the central region is synchrotron radiation, which is produced by interaction between the magnetic field of the central pulsar and the Crab’s nebulous material. This emission heats the surrounding filaments, causing them to glow. Synchrotron radiation is also powering the nebula’s ongoing expansion, distinguishing the Crab from other well-known young supernova remnants. The Crab Nebula is the closest supernova remnant of this kind to Earth, making it invaluable to astronomers using Hubble to study its evolution in unparalleled detail.

Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

This image was acquired by the WFC3 instrument on the Hubble Space Telescope. The color results from assigning different hues (colors) to a monochromatic (grayscale) image. In this case, the assigned colors are: Blue: F502N, Cyan: F547M, Green: F631N, Red: F673N

Compass and Scale
Compass and ScaleAn astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made.
