- A german astronomer named David Fabricius first documented Mira August 3, 1596. He thought it was a nova because it had faded from his view in October. Then he saw it again February 16, 1609.
- In 1638, Johannes Holwarda determined that Mira reappearances were every 11 months. He also named the star "Mira" meaning "wonderful" and "astonishing" in Latin.
- Main Sequence Star; hydrogen to helium
- Red Giant Star ( present ); runs out of helium and expands
- White Dwarf; 90% of its mass is ejected into space ( 10% left )
- Black Dwarf; cools and turns into ashes
NASA’s Galaxy Evolution Explorer Space Telescope revealed that there was a trail of shredded material followed by Mira. This trail was 13 light years in length that was formed over tens of thousands of years. NASA thought it was a hot blow-wave of compressed plasma/gas that caused this trail but it was actually Mira that was moving at an extremely high speed ( 291,000 miles per hour ). Mira had now created stellar wind causing the material to strip from itself.
