The Atmosphere’s Health is Astronomy’s Future
Learn how rocket launches and the demand for satellites threaten astronomy and the ozone layer.
Finding Avatar’s Pandora: Exomoons with Astrometry
Though moons are ubiquitous in our Solar System, we have not yet found one elsewhere (an exomoon). Today’s paper investigates whether we could find moons by precisely tracking the positions of a star and planet.
The Impact of Blazar Shape on Polarization Measurements
Today’s authors consider the way AGN jet shape changes our measurements of blazar polarization.
Twinkle, twinkle, little quasar! Can you tell me how far away you are?
When we don’t have spectra, we can estimate the distance to a quasar by calculating its photometric redshift. Today’s authors present a new way to use the ‘flickering’ of quasars to improve these distance estimates.
A Black Hole Egg that Forgot to Hatch
Giant black holes may have hatched from cosmic eggs. What happens when we find one on our doorstep?
Get back in line! A disc that won’t stay aligned with its planet
Planets should form aligned with their host protoplanetary discs. So why does this star have a planet and disc that aren’t at all in line?
