    The Power of APOD

    When one of my old visualizations was featured on Astronomy Picture of the Day, I was pleased and bemused to revisit it through the eyes of those seeing it anew. It also showed how viral APOD's reach can be, in the vast number of YouTube hits in one day.

    Will Hubble Observe the Recent Gamma-Ray Burst?

    Quickly after its discovery, gamma-ray burst GRB 130427A has been observed by a multitude of telescopes. The Hubble Space Telescope is sometimes employed to follow-up astronomical discoveries, but only when Hubble provides a clear science advantage over other telescopes.

    Episode 16: Deep Universe

    In order to observe the most distant objects in the universe, one needs two things: very fine resolution and very long exposures. Hubble has done a few deep images looking across the universe — unveiling some dramatic findings. To call these observations mind-bending is an understatement.

    Episode 15: Changing Views of Pluto

    While it may seem that the astronomy community's views on Pluto changed radically with its reclassification in 2006, the truth is that our understanding of Pluto has always been shifting. We now comprehend Pluto's place within the solar system, and the exploration of that region has really just begun.

    Episode 14: A Runaway Star

    When a survey of a star-forming region found a star 90 times as massive as the Sun, located hundreds of light-years from its home, and speeding by at a quarter of a million miles per hour — well, that's a surprise that's worth investigating a bit further.

    Episode 13: 20 Years in 20 Images

    In Hubble's first 20 years in orbit, it has taken many thousands of images and observations that have awed astronomers and non-astronomers alike. To commemorate Hubble's 20th anniversary, we select 20 Hubble images that represent the telescope's scientific accomplishments and its impact on the public's imagination.
