A beautiful pair of images, and sums up the challenges I have with my exoplanet research: "Well at least I can measure the proper motion of my candidate exoplanet using the distant background sta- uh oh...."

Two telescopes, two epochs, the same nebula. You might have to stare for a little bit to fully appreciate all the movement going. Apologies to any faint stars who got deleted. I tried to remove the NICMOS PSFs from the Hubble view (which is lower resolution/blurrier)
