Astronaut’s Breathtaking View: Moonglint, Volcanic Aleutians, and Aurora Borealis

The aurora borealis and moonglint shine bright in this astronaut photo of the Alaskan island chain.

An astronaut aboard the International Space Station.

The International Space Station (ISS) is a large spacecraft in orbit around the Earth that serves as a research laboratory and spaceport for international collaboration in space exploration. It was launched in 1998 and has been continuously occupied by rotating crews of astronauts and cosmonauts from around the world since 2000. The ISS is a joint project of five space agencies: NASA (USA), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). It orbits the Earth at an altitude of approximately 400 kilometers (250 miles), and provides a unique platform for scientific research, technological development, and human space exploration.

Quantum Entanglement Waves Detected For The First Time

For the first time, researchers have been able to track the behavior of triplons, a quasi-particle created between entangled electrons. They are very tricky to study and they do not form in conventional magnetic material. Now, researchers have been able to detect them for the first time using real-space measurements.

Quasi particles are not real particles. They form in specific interactions, but for as long as that interaction lasts they behave like a particle. The interaction in this case is the entanglement of two electrons. This pair can be entangled in a singlet state or a triplet state, and the triplon comes from the latter interaction.

To get the triplon in the first place, the team used small organic molecules called cobalt-phthalocyanine. What makes the molecule interesting is that it possesses a frontier electron. Now, don’t go picture some gunslinger particle – a frontier electron is simply an electron on the highest-energy occupied orbital.

What is the next wave after artificial intelligence｜The Singularity Is Near｜#audiobooks

This book, ‘The Singularity Is Near’, predicts the future. However, unlike most best-selling futurology books, its author, Kurzweil, is a renowned technology expert. His insights into the future are not technocratic wild fantasies but are rooted in his profound contemplation of technological principles.

This audio informs us that, due to Moore’s Law, the pace of human technological advancement in the future will far exceed our expectations. By 2045, we will reach the technological ‘Singularity’, which will profoundly alter our human condition, and technology may even enable humans to conquer the universe within a millennium.

The author, Ray Kurzweil, is a true tech maestro. He has been inducted into the National Inventors Hall of Fame in the U.S., is a recipient of the National Medal of Technology, holds 13 honorary doctorates, has been lauded by three U.S. presidents, and is dubbed by the media as the ‘rightful heir to Thomas Edison’.

In the audio, you will hear:

Moore’s Law has been around for 40 years; can it continue?
Why is it said that by 2045, humans will reach a technological Singularity?
Why are future humans described as a set of algorithms?
Is artistic creation the last bastion between humans and artificial intelligence?

India’s moon mission is a low-cost success story, here’s why

In fact, India’s epic Chandrayaan-3 lunar landing was cheaper than a string of Hollywood sci-fi epics.

India successfully performed a soft touchdown near the lunar south pole on Wednesday, August 23, for its Chandrayaan-3 mission.

By doing so, it made history by becoming the first nation to land on that region of the lunar surface as well as the fourth country to ever land on the Moon.

Why the empty atom picture misunderstands quantum theory

The association between this mass concentration and the idea that atoms are empty stems from a flawed view that mass is the property of matter that fills a space. However, this concept does not hold up to close inspection, not even in our human-scale world. When we pile objects on top of each other, what keeps them separated is not their masses but the electric repulsion between the outmost electrons at their touching molecules. (The electrons cannot collapse under pressure due to the Heisenberg uncertainty and Pauli exclusion principles.) Therefore, the electron’s electric charge ultimately fills the space.

Anyone taking Chemistry 101 is likely to be faced with diagrams of electrons orbiting in shells.

In atoms and molecules, electrons are everywhere! Look how the yellow cloud permeates the entire molecular volume in Figure 1. Thus, when we see that atoms and molecules are packed with electrons, the only reasonable conclusion is that they are filled with matter, not the opposite.

Moving around moon, India’s moon rover leaving its imprint on lunar soil

India’s moon rover is now also on the moon, moving around and leaving its imprint on the soil, said a senior official of the Indian space agency.

“The rover rolled down onto the moon surface from the lander sometime around 12.30 a.m. Thursday. It is moving around. It is leaving its imprint on the moon’s surface,” Dr. S. Unnikrishnan Nair, Director, Vikram Sarabhai Space Centre (VSSC) told IANS.

The logo of Indian Space Research Organisation (ISRO) and the national emblem have been engraved on the wheels of the rover to leave the imprint when it moves around.
