Reaching for the Stars
Satellites are proliferating in our low earth orbit. Data from the Steward Observatory characterizes which areas of the sky and which satellite models are the most bright, likely to interfere with astronomical observations.
The Trail with No End: Satellite Streaks in Stellar Spectra
Can we use spectra if it’s polluted with satellite streaks?
Moving Telescopes to Orbit Does Not Outrun Satellite Constellations
A common response to these issues raised by astronomers is to move observational equipment to LEO as well. Today’s paper covers exactly such a case, in which the Hubble Space Telescope still suffers the effects of satellite streaks.
Dust To Dust: The End of Astronomy
The proliferation of space debris is viably the end of space- and ground- based astronomy. Action is required now, before the number of satellites increases hundred-fold.
Hypervelocity Stars, TŻOs, Bumpy Superluminous Supernovae, and Pulsar Planets May All Share An Origin
The collision –or even a near-miss– of a neutron star and a main sequence star can possibly explain long-lived, bumpy supernovae and hypervelocity stars.
