An international research team led by ISTA's Ilaria Caiazzo used the Gemini North telescope to capture the most detailed images of Pa 30, the only known supernova remnant of its kind in the Milky Way. The new observations reveal an unexpectedly complex structure featuring chains of gas knots arranged like pearls on a string, with each knot large enough to contain our solar system multiple times. This supernova remnant is associated with a historical supernova event witnessed approximately 850 years ago.
Why it matters
These findings provide unprecedented detail about a rare type of supernova remnant, offering insights into stellar explosions and their aftermath that cannot be studied elsewhere in our galaxy. Understanding the unique structure and evolution of Pa 30 helps astronomers refine models of stellar death and the distribution of elements in space.
Understand the Science
The only known supernova remnant of its kind in the Milky Way has an unexpectedly intricate structure: chains of gas knots resembling pearls on a string, each wide enough to fit the solar system multiple times. Using the Gemini North telescope, an international team co-led by Ilaria Caiazzo, assistant professor at the Institute of Science and Technology Austria (ISTA), captured the most detailed view yet of Pa 30, revealing striking new features of the remnant associated with a historical supernova witnessed nearly 850 years ago. The findings are published in The Astrophysical Journal.
