Briefings

An international team led by Ilaria Caiazzo at ISTA used the Gemini North telescope to capture the most detailed view of Pa 30, a unique supernova remnant in the Milky Way. The remnant features intricate chains of gas knots resembling pearls, each wide enough to fit the solar system multiple times. This discovery is associated with a historical supernova witnessed nearly 850 years ago, and the findings are published in The Astrophysical Journal.

Key points

• The Gemini North telescope captured the most detailed view of Pa 30, revealing chains of gas knots resembling pearls.
• Each gas knot in the chains is wide enough to fit the solar system multiple times.

Context and limitations

The study focuses on Pa 30, the only known supernova remnant of its kind in the Milky Way. The Gemini North telescope data provides the most detailed view yet, but specific limitations on the full extent of the chains or the historical supernova's exact location are not detailed in the provided evidence.
