On the afternoon of February 10, 2009, the operational communications satellite Iridium 33 collided with the obsolete Cosmos 2251 communications satellite over Siberia at an altitude of roughly 800 kilometers. The collision was at a speed of 11.7 kilometers a second and produced a cloud of more than 2,000 pieces […]
Beyond “Fermi’s Paradox” VII: The Planetarium Hypothesis
Welcome back to our Fermi Paradox series, where we take a look at possible resolutions to Enrico Fermi’s famous question, “Where Is Everybody?” Today, we examine the possibility that we can’t see them because they have us all inside a massive simulation!

Comet NEOWISE Was Spiraling and Spinning as it Passed by Earth
Earlier this week, we shared an image of Comet NEOWISE (C/2020 F3) taken by the Hubble Space Telescope. And now, here are a group of images from the 8.1-metre Gemini North telescope in Hawaii. Like Hubble, Gemini North focused in on the comet’s nucleus and coma, instead of its stunning, […]
New study questions decades of research on the evolution of spiral galaxies
Previous studies on the formation and evolution of spiral galaxies might have been based on an incorrect assumption, suggests a team of researchers of Instituto de Astrofísica e Ciências do Espaço (IA).
