NASA says: This image of comet Lovejoy C/2014 Q2 combines a series of observations made in November 2013, when comet Lovejoy was 1.7 astronomical units from the sun. (An astronomical unit is the distance between Earth and the sun.
The red color is caused by the strong signal in the NEOWISE 4.6-micron wavelength detector, owing to a combination of gas and dust in the comet's coma.
But UFOvni2012 disagrees with NASA's explanation.
UFOvni2012 says: NASA tries to pass off this photo as a comet, but when has a comet every looked red?
No comet could emit a red light as it travels though space, however a static field around a spaceship could create such a color.

This is a UFO seen in 5 different positions. I ask you, have you ever seen a comet glowing red?
