description N70 Overview

N70, also known as Henize 70, is a large emission structure and superbubble in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. It consists of gas shaped and energized by massive stars, stellar winds, and supernova activity, producing an expanding cavity that spans hundreds of light-years. Its Henize designation comes from Karl Henize's 1956 catalog of emission nebulae.

help N70 FAQ

What is N70, or Henize 70?

N70 is a large emission structure and superbubble in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. It is also known by the catalog name Henize 70.

What creates the cavity inside N70?

Massive stars in the region produce strong stellar winds and eventually supernova explosions. Those forces push and energize surrounding gas, creating the expanding superbubble structure.

Is N70 inside the Milky Way?

No. N70 is in the Large Magellanic Cloud, which orbits the Milky Way as a nearby satellite galaxy. That makes it an extragalactic object even though it is relatively close on cosmic scales.

Why is N70 called an emission structure?

Its gas is energized by hot stars and high-energy stellar activity, causing it to emit light at characteristic wavelengths. Astronomers can study that emission to learn about feedback from massive stars.
