The Green Comet Lulin is seen (center-right) in the Constellation Leo near the Planet Saturn (center-left) on Monday Night, Feb. 23, 2009 from Tyler, Texas while a high altitude plane flies right to left in this 12 sec. time exposure. The Comet is visible in dark areas to the unaided eye as a faint green patch, while it makes its closest approach to the Earth tonight, about 38 Million miles. It is visible between 11PM and the dawn.
