Space junk could one day be snatched in orbit with a strong bag, if a new contract to test the technology ends up flying in space.

The U.S. Central Intelligence Agency has released a new entry in its World Factbook that catalogues the programs and milestones of space agencies around the world.
Some of the world’s leading astronomical observatories have reported cyberattacks that have resulted in temporary shutdowns.
The National Science Foundation’s National Optical-Infrared Astronomy Research Laboratory, or NOIRLab, reported that a cybersecurity incident that occurred on Aug. 1 has prompted the lab to temporarily halt operations at its Gemini North Telescope in Hawaii and Gemini South Telescope in Chile. Other, smaller telescopes on Cerro Tololo in Chile were also affected.
The James Webb Space Telescope has revealed colorful new portraits of the iconic Ring Nebula that capture unprecedented details a dying star creates glowing structures.
A new hypothesis suggests that the universe may be twice as old as we had believed. Observations from the James Webb Space Telescope provide new information on the rate of the universe’s expansion.
Chandrayaan-3 creates first temperature profile near the moon’s south pole; ISRO offers more updates on the historic lunar mission.

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.
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.
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’.
