Summary

Story summary

A study published on December 10, 2025, focuses on predicting satellite trails for space telescopes, including Hubble, SPHEREx, and ARRAKIHS, to understand the impact on observations with fixed exposure times.
The research uses data from the Planet4589 database and simulates satellite constellations and their visibility from different telescope altitudes.
Findings show lower limb angles increase the likelihood of detecting satellite trails.
Trail brightness depends on satellite distance and orientation.
