Humanity is slowly losing access to the night sky, and astronomers have invented a new term to describe the pain associated with this loss: “noctalgia,” meaning “sky grief.”
Along with our propensity for polluting air and water and the massive amounts of carbon we’re dumping into the atmosphere to trigger climate change, we have created another kind of pollution: light pollution.
The universe naturally gravitates towards disorder, and only through the input of energy can we combat this inevitable chaos. This idea is encapsulated in the concept of entropy, evident in everyday phenomena like ice melting, fires burning, and water boiling. However, zentropy theory introduces an additional layer to this understanding.
This theory was developed by a team led by Zi-Kui Liu, the distinguished Dorothy Pate Enright Professor of Materials Science and Engineering at Penn State. The “Z” in zentropy is derived from the German term “Zustandssumm,” which translates to the “sum over states” of entropy.
Alternatively, Liu said, zentropy may be considered as a play on the term “zen” from Buddhism and entropy to gain insight on the nature of a system. The idea, Liu said, is to consider how entropy can occur over multiple scales within a system to help predict potential outcomes of the system when influenced by its surroundings.
A seven-year NASA mission is only just beginning as a capsule lands on Earth this weekend bringing with it some valuable cargo.
The discovery made using NASA’s powerful space telescope brings scientists a step closer to determining if the salty water oceans of Europa could support life.
In the extreme hearts of neutron stars, fundamental particles are twisted into strange ‘pasta’ shapes that could reveal untold secrets about how dead stars evolve.
The actor told The Telegraph what he could offer NASA while promoting his immersive film “The Moonwalkers.”
Data centre energy consumption could be cut with new, ‘breakthrough’ photonic chips that are more efficient than today’s chips.
Data centres can consume up to 50 times more energy per square foot of floor space than a typical office building and account for roughly 2 per cent of all electricity use in the US.
In recent years, the number of data centres has risen rapidly due to soaring demand from the likes of Facebook, Amazon, Microsoft and Google.
This will be good for future deep space spaceships faring high energy ejections on their hulls.
The sun-kissing spacecraft watched as dust particles were displaced across 6 million miles (9.7 million kilometers).
The mosaic reveals unprecedented detail of the lunar South Pole region and highlights a scenic crater called the Shackleton Crater.
Space Warfare concepts from science fiction often involve war between planets, and we will discuss the science of that, and war inside a fully colonized solar system or Dyson Swarm.
