Synopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Local Bubble is a cavity in the interstellar medium (ISM) of the Orion Arm of the Milky Way. It is at least 300 light years across and has a neutral hydrogen density of about 0.05 atoms per cubic centimetre, or approximately one tenth of the average for the ISM in the Milky Way (0.5 atoms/cc), and half that for the "Local Fluff," or Local Interstellar Cloud (0.1 atoms/cc). The hot diffuse gas in the Local Bubble emits X-rays. The very sparse, hot gas of the Local Bubble is the result of supernovae that exploded within the past two to four million years. The most likely candidate for the remains of this supernova is "Geminga" ("Gemini gamma-ray source"), a pulsar in the constellation Gemini.
