The riddle posed by super-Earths (1 — 4 Earth radii, 2 — 20 Earth masses) is that they are not Jupiters: their core masses are large enough to trigger runaway gas accretion, yet somehow super-Earths accreted atmospheres that weigh only a few percent of their total mass.

Building on past observations of the white dwarf called SDSSJ1043 +0855 (the dead core of a star that originally was a few times the mass of the Sun), which has been known to be gobbling up rocky material in its orbit for almost a decade, the team used Keck Observatory's HIRES instrument fitted to the 10 - meter Keck I telescope as well as data from the Hubble Space Telescope to measure and characterize the material being accreted by the star.

In addition to extending a relatively new method of determining the chemical composition of planets to examine their internal structure, the team found that the rocky material being accreted by the star could be comprised of minerals that are typically associated with marine life processes here on Earth.

SDSS studies have probed the dark matter environments of quasars through clustering measurements, revealed populations of quasars whose central engines are hidden by obscuring dust, captured changes in quasar spectra that show clouds moving in the gravitational grip of the central black hole, and allowed a comprehensive census of the much fainter accreting black holes (active galactic nuclei, or AGN) in present - day galaxies.
