SETI faces a practical problem: with billions of stars and limited telescope time, which ones to listen to?
Most SETI programs prioritize proximity, but not all stars are good candidates for hosting complex life.
Sahin Torlakcik, a high school student, created the Torlakcik Catalog using seven stellar parameters to filter out unlikely stars.
The catalog removes stars that are too massive, too young, metal-poor, in binary systems, or have high variability/activity.

Researchers say the Milky Way’s star-forming disc ends roughly 40,000 light-years from the galactic center.
The conclusion comes from age analysis of more than 100,000 giant stars using several survey datasets.
Older stars beyond that boundary are thought to be migrants pushed outward by spiral arms or the central bar.

Researchers used Gaia data and a new algorithm to identify dozens of faint stellar-stream candidates.
The reported method more than quadruples the number of known candidates.
The findings could help explain both Milky Way evolution and dark matter distribution.

Scientists found evidence the Sun may have migrated from the Milky Way's dense inner regions to the calmer outer disk billions of years ago
Radial migration driven by gravitational interactions with spiral arms can move stars large distances over billions of years
The quieter outer disk may have been a necessary condition for Earth's long-term habitability
