Eta Carinae Nebula in 3D

Part of the story from the YouTube site:

Between 1838 and 1845, Eta Carinae underwent a period of unusual variability during which it briefly outshone Canopus, normally the second-brightest star. As a part of this event, which astronomers call the Great Eruption, a gaseous shell containing at least 10 and perhaps as much as 40 times the sun’s mass was shot into space. This material forms a twin-lobed dust-filled cloud known as the Homunculus Nebula, which is now about a light-year long and continues to expand at more than 1.3 million mph (2.1 million km/h).

Reminder: Cygnus is ready to launch at 16:52 UTC (12:52 EDT). Check this post to see if you can see the Cygnus and Antares rocket as it goes into orbit.

  1. Now that was fascinating. I did not know that it was a double star system of two massive stars.
