What Nanomaterials Are Used in Space?
Future space missions aim to reach Mars and beyond, but many challenges must be overcome before this can be achieved – and nanomaterials will play a critical role. From bio-nano robot-laced spacesuits, to radiation shielding, to new means of travelling into space, research employing nanomaterials is underway. https://www.azonano.com/article.aspx?ArticleID=4983

Content of the Universe Pie Chart (Chart)
Planck data reveals that the universe’s contents include 4.9% ordinary matter, or atoms, the building blocks of stars and planets. Dark matter comprises 26.8% of the universe. This matter, different from atoms, does not emit or absorb light. It has only been detected indirectly by its gravity. 68.3% of the universe, is composed of “dark…

Underwater neutrino detector will be second-largest structure ever built (article)
The hunt for elusive neutrinos will soon get its largest and most powerful tool yet: the enormous KM3NeT telescope, currently under development by a consortium of 40 institutions from ten European countries. Once completed KM3NeT will be the second-largest structure ever made by humans, after the Great Wall of China, and taller than the Burj…

Quantum SHAPE-SHIFTING: Neutrino Oscillations (video)
This video is about the phenomenon of neutrino oscillations, which is where neutrinos can change flavors (ie, change between electron, muon, or tau neutrinos) because those interaction states are in non-trivial superpositions of the free traveling/mass eigenstates (𝜈1, 𝜈2 and 𝜈3).

On the Origins of “We Are Stardust”(article)
Most of us are familiar with the saying, made popular by astronomer Carl Sagan, folk singer Joni Mitchell, and countless inspirational posters and billboards—We are stardust. Yet, how do we know that we’re stardust? Put another way, what’s the observational evidence that we’re made of elements forged in dying stars? Part of it is here…

How to Build a Space Colony | Visualizing The Future (video)
Imagine a sprawling megastructure floating endlessly through space. One day, humans may occupy an orbital settlement several hundred kilometers from Earth. Perhaps, humans will settle closer to the moon, or in the main asteroid belt beyond Mars. If humans ever migrate into space, what would our settlement look like, and how would we navigate life…
