End of November, footage of a coronal mass ejection highlighted a planet-sized object hanging around Mercury.
Although some think it’s a UFO, other scientists say that it’s Mercury itself. Head NRL group scientist Russ Howard and lead ground systems engineer Nathan Rich say:
To make the relatively faint glow of a coronal mass ejection stand out against the bright glare of space—caused by interplanetary dust and the stellar/galactic background—the NRL scientists must remove as much background light as possible. They explained that they determine what light is background light, and thus can be subtracted out, by calculating the average amount of light that entered each camera pixel on the day of the CME event and on the previous day. Light appearing in the pixels on both days is considered to be background light and is removed from the footage of the CME. The remaining light is then enhanced.
Hmm, makes sense, but nowhere near as fun as giant, alien UFOs.
So, what do you think it is?
