Planetary Family Portrait: HR 8799
Credit: Project 1640
This image shows the HR 8799 planets with starlight optically suppressed and data processing conducted to remove residual starlight. The star is at the center of the blackened circle in the image. The four spots indicated with the letters b through e are the planets. A team of researchers belonging to a group called Project 1640, which is partly funded by NASA's Jet Propulsion Laboratory, Pasadena, Calif., used the Palomar Observatory near San Diego to obtain detailed spectra of the four planets.
