Twenty-Two Bow Shocks: Astronomers Catch the Helix Nebula Recycling a Dying Star's Debris in Real Time
A partially built telescope in Chile has resolved 22 distinct bow shocks in the Helix Nebula's outskirts, giving astronomers a rare direct measurement of how a dying star's ejecta gets shredded and mixed back into the galaxy over roughly 10,000 years.
