Summary

Story summary

The Hubble Space Telescope revisited the Crab Nebula, about 6,500 light-years away, releasing images that reveal its filamentary structure and a 25-year expansion at 3.4 million miles per hour, published in The Astrophysical Journal.
Lead astronomer William Blair notes that edges moved outward without stretching, driven by the pulsar's synchrotron radiation.
The findings will advance understanding of the Crab Nebula's evolution and its ties to historical records.
