The Trail with No End: Satellite Streaks in Stellar Spectra
Can we use spectra if it’s polluted with satellite streaks?
Can we use spectra if it’s polluted with satellite streaks?
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.
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.
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.
How does one measure the gravitational wave signal of a supernova if each event is unique? Is machine learning up to the task? Or is it unknowable?
