Witnessing a Planetary Wreckage

Astronomers were surprised to see these data from NASA's Spitzer Space Telescope in January 2013, showing a huge eruption of dust around a star called NGC 2547-ID8. In this plot, infrared brightness is represented on the vertical axis, and time on the horizontal axis.

This artist's concept shows the geometry of a space telescope aligned with a starshade Starshade Would Take Formation Flying to Extremes

To hunt for exoplanets, the flowerlike shade would need to stay aligned with a space telescope over vast distances. Recent work demonstrates how that's possible.
