Study using radio telescope data finds most geostationary satellites emit little unintended radio interference in frequencies used for astronomy ...

Researchers at the University of Hawaii Institute for Astronomy (IfA) are helping reshape how scientists study the Sun.

Satellites reflect sunlight, Earthshine, infrared and radio waves.

For generations, school posters have sorted the Solar System into tidy boxes: four small rocky planets near the Sun, two huge gas planets farther out, and, at the edge, a pair of “ice giants” – Uranus ...

Astronomers have long been concerned about reflections from satellites showing up in images taken by telescopes and other ...

Recent research challenges the prevailing theory that hot Jupiters (gas giants orbiting close to their stars) form through a disruptive process that prevents the existence of smaller planets in the ...

Alfred University is home to the Stull Observatory and its seven independent telescopes, but relatively few students have chosen to take advantage of those resources in the form of a minor in ...

A new study provides evidence that SpaceX Starlink satellites are emitting electromagnetic radiation in orbit — and this has the potential to disrupt astronomical observations. “This study represents ...

As SpaceX, Amazon, and others vie for supremacy in the race to establish constellations of communications satellites, the superhighway used by low-Earth orbit (LEO) satellites is becoming dangerously ...

The COVID-19 pandemic has had both positive and negative impacts on astronomy research, where overall the number of research papers being produced increased, but the number of new or junior ...
