@JaviAlonSaso @esa @NASA Motion! That was just one frame of about a dozen in which we could track it

[Javier Alonso @JaviAlonSaso]

@SungrazerComets @esa @NASA How are you able to spot such a small comet relative to the picture?

[Andrew Rader @marsrader]

@JaviAlonSaso Phosphorescent microorganisms cause the glow (algae that absorb light and later give it off).

@marsrader what is that glowing thingy?

Will hate that @Astro_Alex & @astro_reid will no longer be in space. Their images are breathtaking & one of the best parts of Twitter.
