Orion–Eridanus Superbubble

Orion–Eridanus Superbubble

The Orion–Eridanus Superbubble, or Eridanus Soft X-ray Enhancement is a superbubble in the Orion Nebula. The region is formed from overlapping supernova remnants that may be be associated with the Orion OB1 stellar association; the bubble is approximately 1200 ly across.[1] It is the nearest superbubble to the Local Bubble containing the sun, with the respective shock fronts being about 500 ly apart.[1]

The structure was discovered from 21 cm radio observations by Carl Heiles in the 1970s.[2]
