Sorry about the scarcity of posts last week. Ferrebeekeeper opted to enjoy an extended Fourth of July by trying not to look at the internet (which paints a less-than-rosy picture of these (dis)United States of America). I was out experiencing summer fun in the real world. But that doesn’t mean we have forgotten about fireworks of the past. We have just moved our perspective farther afield.
Above is the highest resolution image of Eta Carinae taken by the NASA/ESA Hubble Space Telescope. Between 1838 and 1844 Eta Carinae nearly went supernova and briefly became the fourth brightest star in the heavens (well really the explosion/ejection event occurred 7500 years earlier and the photons only reached Earth in the mid-nineteenth century). Astronomers are still arguing about what exactly transpired then in this messed up stellar system: one particularly dramatic theory is that the unstable blue super giant η Car A devoured a now unknown third star in the system!
In the actual universe Eta Carinae is almost certainly gone and a vast tsunami of strange electromagnetic radiation is rushing towards Earth…but nobody knows if this is true or when the supernova afterwash will get here. Astronomers recently pointed Hubble at the Homunculus Nebula, the hourglass shaped cloud of matter which expands approximately one light year from the binary Eta Carinae system and took the color enhanced ultraviolet photo above. It is beautiful but ominous…let’s keep it in the back of our minds as we go about our little lives. This universe is a strange & savage place.
