Artificial Afterlives

Posted by in categories: habitats, media & arts, space

The afterlife Jones made.


For as long as we have had history and likely before, people have contemplated a life after this one, but might we one day create artificial afterlives? And if so, will we create heavens or hells?\

China launches secret space plane on 3rd-ever mission

Posted by in category: space

Hours prior to the secretive spacecraft’s launch, SpaceX stood down from the 7th planned liftoff of the U.S. Space Force’s own X-37B reusable space plane, and even removed the Falcon Heavy rocket containing it from the Kennedy Space Center launch pad. The mission, known as USSF-52, was scrubbed on Wednesday (Dec. 13) to “perform additional system checkouts.” Exact reasons for this delay remain unknown, and a new date has yet to be set for launch.

Much like the X-37B, little is known about China’s reusable space plane, subbed Shenlong, or “Divine Dragon.” From what bits of information are available to the public, though, the spacecraft appears to be used for testing new payloads and orbital operations. It launches vertically atop a rocket, conducts its mission and then lands horizontally on a runway similar to NASA’s space shuttle.

Gravitational Waves Unveil Thermal Secrets in Neutron Star Mergers

Posted by in categories: physics, space, supercomputing

Simulations of binary neutron star mergers suggest that future detectors will distinguish between different models of hot nuclear matter.

Researchers used supercomputer simulations to explore how neutron star mergers affect gravitational waves, finding a key relationship with the remnant’s temperature. This study aids future advancements in detecting and understanding hot nuclear matter.

A bend in universe: Researchers may have discovered the cosmic string proof

Posted by in categories: physics, space

A recent analysis of a peculiar pair of galaxies located billions of light-years away suggests the possibility of a cosmic string —a hypothetical feature in the fabric of the Universe. Initially considered distinct, the two galaxies may be duplicated images caused by gravitational lensing, a phenomenon where space-time bends around foreground mass, acting like a lens.

Led by researchers of the Indian Institute of Astrophysics, the study identifies a cosmic string candidate, CSc-1, in the cosmic microwave background, the lingering radiation from the Universe’s birth. Cosmic strings, theoretical one-dimensional wrinkles formed at the dawn of time, are believed to be highly dense and massive, potentially extending across the entire Universe.

Observationally proving cosmic strings is challenging because their effects can resemble other phenomena. However, minute differences in their impact distinguish them. The researchers focused on a galaxy pair, SDSSJ110429, within CSc-1 as a potential cosmic string signature. Gravitational lensing typically involves a foreground mass causing observable distortions, but SDSSJ110429 lacks evident foreground mass or distorted light.

Can Signs of Life be detected from Saturn’s Frigid Moon?

Posted by in categories: energy, physics, space

Enceladus’ ice plumes may hold the building blocks of life. Researchers have shown unambiguous laboratory evidence that amino acids transported in the ice plumes of Saturn’s moon, Eceladus, can survive impact speeds of up to 4.2 km/s, supporting their detection during sampling by spacecraft.

As astrophysics technology and research continue to advance, one question persists: is there life elsewhere in the universe? The Milky Way galaxy alone has hundreds of billions of celestial bodies, but scientists often look for three crucial elements in their ongoing search: water, energy and organic material. Evidence indicates that Saturn’s icy moon Enceladus is an ‘ocean world’ that contains all three, making it a prime target in the search for life.

During its 20-year mission, NASA’s Cassini spacecraft discovered that ice plumes spew from Enceladus’ surface at approximately 800 miles per hour (400 m/s). These plumes provide an excellent opportunity to collect samples and study the composition of Enceladus’ oceans and potential habitability.

The Great Solar Wind Disappearance: Groundbreaking Discovery by NASA’s MAVEN Mission

Posted by in categories: particle physics, space

In December 2022, NASA’s MAVEN mission observed a rare solar event causing the solar wind to “disappear.” This led to significant changes in Mars’ atmosphere and magnetosphere, including their expansion. Scientists, astounded by the data, formed a working group to study this phenomenon. Credit: SciTechDaily.com.

NASA ’s MAVEN detected a unique solar event that drastically affected Mars ’ atmosphere, offering vital insights into the planet’s interaction with solar phenomena.

Artificial Intelligence, Quantum Computing, and Space are 3 Tech areas to Watch in 2024

Posted by in categories: business, quantum physics, robotics/AI, space

By Chuck Brooks


Every new year creates a new opportunity for optimism and predictions. In the past couple of years, emerging technology has permeated almost all areas of our lives. There is much to explore! In this article, I focus on three evolving technology areas that are already impacting our future but are only at the early stages of true potential: artificial intelligence, quantum computing, and space systems.

In addition to my own thoughts and perspectives, I reached out to several well-known subject matter experts on those very topic areas to share their valued insights.

New plasma instability sheds light on the nature of cosmic rays

Posted by in categories: particle physics, space

Scientists from the Leibniz Institute for Astrophysics Potsdam (AIP) have discovered a new plasma instability that promises to revolutionize our understanding of the origin of cosmic rays and their dynamic impact on galaxies.

At the beginning of the last century, Victor Hess discovered a new phenomenon called that later on earned him the Nobel prize. He conducted high-altitude balloon flights to find that the Earth’s atmosphere is not ionized by the radioactivity of the ground. Instead, he confirmed that the origin of ionization was extra-terrestrial. Subsequently, it was determined that cosmic “rays” consist of charged from flying close to the speed of light rather than radiation. However, the name “cosmic rays” outlasted these findings.

In the new study, Dr. Mohamad Shalaby, scientists at AIP and the main author of this study, and his collaborators have performed to follow the trajectories of many cosmic ray particles and study how these interact with the surrounding plasma consisting of electrons and protons. The paper appears on the pre-print server arXiv.
