To boldly go where no star has gone before
More than 100 massive stars orbit the supermassive black hole at the center of our galaxy incredibly closely.
The APOGEE Treasure Trove
The three-year APOGEE survey was designed to target red giant stars in the Milky Way using near-infrared light, and today’s paper marks the final data release: half a million spectra of 146,000 stars. This treasure trove of data will be put to good use for years to come.
