A multiwavelength mystery solved

Caption

Composite image of the HD 53143 star system. Shown in orange/red, millimeter-wavelength data from Atacama Large Millimeter/submillimeter Array (ALMA), reveal a previously unobserved eccentric debris disk orbiting HD 53143 in the form of an ellipse. Am unresolved dot shows the star off-center near the southern foci of the disk, while a second unresolved dot to the north indicates the potential presence of a planet. Optical data from the Hubble Space Telescope’s Advanced Camera for Surveys (ACS) is shown in blue and white; a coronagraphic mask blocks out the starlight, allowing researchers to see what’s happening in the region surrounding HD 53143.
