Image on the left shows several Jupiter mass binary objects in the Trapezium Cluster of the Orion nebula. Binary objects of such small mass were believed to be quite rare, and yet in this survey they are relatively common.
The chart of the right shows the unexpected U-shape based on this work. Prior to this survey, the percentage of wide binaries decreased as mass decreased. The red on the chart is from this survey and shows that the trend reverses at the lowest masses. This is not generally consistent with current theory of planet and star formation, and suggests potentially a new theory of how such objects could form.
