Massive Star Pair's Double Supernova Stuns Scientists
21 Jul
Summary
- Two massive stars in a binary system exploded as supernovas.
- Evidence found using NASA's Fermi Gamma-ray Space Telescope.
- Nebulas from these explosions are located 6,000 light-years away.
Most massive stars are born in binary systems, but a recent discovery has provided the first evidence of a pair where both stars met their end through violent supernova explosions. These catastrophic events, relatively close in cosmic time, have left behind observable remnants. Scientists utilized over 16 years of data from NASA's Fermi Gamma-ray Space Telescope to identify these stellar remnants.
The study revealed two nebulas, including the well-known Jellyfish Nebula (IC 443). Researchers believe these formations are the aftermath of two massive stars, each at least 15 to 25 times the mass of our sun, exploding sequentially. The companion star's explosion occurred an estimated 20,000 to 110,000 years after the first.
These exploding stars, living brilliant but short lives compared to our sun, are thought to have each left behind a neutron star. The two nebulas are located about 6,000 light-years away in the constellation Gemini. This discovery offers a rare chance to study the complete lifecycle of massive binary stars and understand how binary companions affect stellar evolution.
