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.

Meteorites likely Source of Nitrogen for Early Earth

Posted by in categories: materials, space

Results of study from Ryugu samples.

Micrometeorites originating from icy celestial bodies in the outer Solar System may be responsible for transporting nitrogen to the near-Earth region in the early days of our solar system. That discovery was published today in Nature Astronomy by an international team of researchers, including University of Hawai’i at Manoa scientists, led by Kyoto University.

Nitrogen compounds, such as ammonium salts, are abundant in material born in regions far from the sun, but evidence of their transport to Earth’s orbital region had been poorly understood.

Is Information Fundamental?

Posted by in categories: energy, space

What if the fundamental “stuff” of the universe isn’t matter or energy, but information?

That’s the idea some theorists are pursuing as they search for ever-more elegant and concise descriptions of the laws that govern our universe. Could our universe, in all its richness and diversity, really be just a bunch of bits?

To understand the buzz over information, we have to start at the beginning: What is information?

Cosmic nuclear fission seen for 1st time in ‘incredibly profound’ discovery

Posted by in categories: nuclear energy, space

“The only plausible way this can arise among different stars is if there is a consistent process operating during the formation of the heavy elements,” Mumpower said. “This is incredibly profound and is the first evidence of fission operating in the cosmos, confirming a theory we proposed several years ago.”

“As we’ve acquired more observations, the cosmos is saying, ‘hey, there’s a signature here, and it can only come from fission.’”

Neutron stars are created when massive stars reach the end of their fuel supplies necessary for intrinsic nuclear fusion processes, which means the energy that has been supporting them against the inward push of their own gravity ceases. As the outer layers of these dying stars are blown away, the stellar cores with masses between one and two times that of the sun collapse into a width of around 12 miles (20 kilometers).
