Update on Arecibo Observatory Facility After Telescope Damage
Sep 11, 2020 (SPX)
Today marks 30 days since the Arecibo Observatory went offline, because an auxiliary cable broke and damaged the dish and Gregorian Dome. While no cause has yet...
Massive halo finally explains stream of gas swirling around the Milky Way
Sep 10, 2020 (SPX)
As the Magellanic Clouds began circling the Milky Way billions of years ago, an enormous stream of gas known as the Magellanic Stream was ripped from them. The ...
Reporting from the stars

New study questions decades of research on the evolution of spiral galaxies
Aug 27, 2020 (SPX)
This common assumption is challenged in a study, published in Astronomy and Astrophysics and authored by Iris Breda, Polychronis Papaderos and Jean Michel Gomes...
Cosmic rays may soon stymie quantum computing
Aug 27, 2020 (SPX)
But that all depends on a qubit's integrity, or how long it can operate before its superposition and the quantum information are lost - a process called decoher...
Ancient star explosions revealed in the deep sea
Aug 26, 2020 (SPX)
Professor Anton Wallner, a nuclear physicist at ANU, led the study which shows the Earth has been travelling for the last 33,000 years through a cloud of faintl...
