Astronomers, using NASA’s Chandra X-ray Observatory and the Hubble Space Telescope, have unveiled a mesmerizing cosmic phenomenon—a nebula that bears a striking resemblance to a flame-throwing guitar. Dubbed the Guitar Nebula, this extraordinary celestial formation showcases the dynamic energy of a pulsar, delivering a cosmic spectacle akin to a rock concert in space.
The Rocking Formation: A Celestial Guitar
At the heart of the Guitar Nebula lies pulsar PSR B2224+65, a highly magnetized, rotating neutron star. Pulsars emit regular radiation pulses, much like a lighthouse beacon. In this case, the pulsar’s powerful energy has created a stunning shape resembling a guitar, complete with fiery filaments.

According to NASA, “The guitar shape comes from bubbles blown by particles ejected from the pulsar through a steady wind.” As the pulsar moves through regions of varying density, these bubbles create the nebula’s unique structure. The pulsar itself is moving diagonally from the lower right to the upper left of the nebula.
Chandra and Hubble Reveal the Details
The discovery was highlighted through a captivating NASA video, showcasing Chandra’s data. The observatory captured a filament of energetic particles and antimatter stretching about two light-years (12 trillion miles), emerging like a blazing flame from the guitar’s “tip.”
Complementing Chandra’s findings, the Hubble Space Telescope provided long-term observations spanning over two decades. These observations revealed the motion of the pulsar and the intricate patterns forming the nebula.
Cosmic Insights from the Flame-Throwing Guitar
The study, published in The Astrophysical Journal, reveals that density variations within the surrounding hydrogen nebula influence both the guitar shape and the brightness of the X-ray filament. This filament, resembling a cosmic blowtorch, sheds light on how electrons and positrons traverse the interstellar medium and inject energetic particles into space.
The Guitar Nebula’s discovery not only highlights the universe’s artistic wonders but also offers critical insights into the behavior of pulsars and the interaction of particles in deep space.
