"This newly processed image comes from data originally captured by NASA’s Hubble Space Telescope in 1999 and 2000. The color assignments in this image have been matched to those used in the new 2024 data, providing a better comparison."

Chinese astronomers noticed a star burning brightly in the daytime that persisted for three weeks, back in 1054 A.D.—and they weren’t alone. On the other side of the globe, Mayan stargazers recorded the same brilliant celestial phenomenon.

What they witnessed, according to famed astronomer Edwin Hubble writing almost 900 years later, wasn’t a star at all but rather the explosive death of one. That dazzling supernova would later become the Crab Nebula, and the space telescope that bears Hubble’s name recently snapped an incredible picture of it a quarter century after the first image it took.

THE FATE OF OUR STARS: By comparing the first photo of the Crab Nebula, taken 25 years ago (left) with the latest photo, taken in 2024, astronomers can see how the nebula has changed over time. It appears that the edges have changed more than the center. Images courtesy of (left) NASA, ESA, J. Hester and A.

By comparing the two images, NASA astronomers like William Blair of Johns Hopkins University can track how the nebula has evolved over time. According to Blair, the newly released image shows how the filaments of gas at the outer edges of the nebula have moved more over the past 25 years than those closer to the center. Rather than simply stretching farther outward, they appear to be moving away from the center of the nebula. That’s because at the heart of the gas cloud lies a rapidly spinning neutron star—a pulsar—whose magnetic field whips the gas into a rapidly moving whirlwind of charged particles. The outer filaments of the Crab Nebula are estimated to be moving at 3.4 million miles per hour.

“We tend to think of the sky as being unchanging, immutable,” Blair said in a statement. “However, with the longevity of the Hubble Space Telescope, even an object like the Crab Nebula is revealed to be in motion, still expanding from the explosion nearly a millennium ago.”
Ancient astronomers never could have even imagined getting a view like this. ![]()
