NASA’s Chandra X-ray Observatory and Hubble Space Telescope captured the “Guitar Nebula”
Summary:
NASA’s Chandra X-ray Observatory and Hubble Space Telescope captured the “Guitar Nebula,” a pulsar-powered structure resembling a glowing guitar. The pulsar PSR B2224+65 emits a two-light-year-long filament of high-energy particles and antimatter as it moves through space. This unique phenomenon results from the pulsar’s rapid rotation and strong magnetic fields, reversing Einstein’s

equation to convert energy into matter. The filament’s behavior reveals how particles travel and interact in the interstellar medium, offering valuable insights into space physics.
Astronomers using NASA’s Chandra X-ray Observatory and Hubble Space Telescope have observed a unique cosmic phenomenon: the “flame-throwing” Guitar Nebula, named for its distinct guitar-like shape in glowing hydrogen light. The nebula is driven by the pulsar PSR B2224+65, a swiftly spinning neutron star formed from the remnants of a collapsed massive star.
As the pulsar hurtles through space, it ejects high-energy particles in a steady wind, forming bubble-like structures that create the guitar shape. At the tip of the “guitar,” the pulsar emits a two-light-year-long filament of energetic matter and antimatter particles, visible in Chandra’s X-ray data.
This bizarre structure is the result of the pulsar’s extreme rotation and intense magnetic fields, which accelerate particles and generate high-energy radiation. In a reversal of Einstein’s famous equation \(E = mc^2\), energy is converted into mass, producing pairs of matter and antimatter particles.
The filament arises when the pulsar and its energetic particles collide with denser regions of gas, allowing the highest-energy particles to escape. These particles spiral along magnetic field lines, creating the X-ray “flame” seen in the nebula.
Time-lapse movies from Chandra (2000–2021) and Hubble (1994–2021) reveal the pulsar’s motion and variations in the nebula’s structure over decades. Researchers concluded that changes in the nebula’s density influence both the formation of the guitar’s bubbles and the intensity of the escaping X-ray filament.
This cosmic “blow torch” provides insights into how electrons and positrons travel through interstellar space and how these particles are injected into the interstellar medium, enhancing our understanding of space’s dynamic processes.
