Spintronics is an emerging field of basic and applied research in physics and engineering where the “neglected” magnetic degree of freedom of an electron, its spin, is envisaged to be exploited for classical and quantum information processing. While metallic spintronics has already delivered functional devices (GMR read heads in large capacity hard disk drives), and … Continue reading Understanding Spintronics: Key Challenges and Innovations
New simulations show that magnetic field interactions can decrease the distance between still-forming binary protostars. These results can help explain the characteristics of the binary star systems observed in the Milky Way. The results can also be extrapolated to binary black holes, giving insights into how supermassive black holes evolve. The work is published in … Continue reading New Simulations Reveal Binary Black Hole Formation Secrets
Tightly spaced planets inside an alien solar system known as Kepler-80 boast a rare orbital configuration. Mariah MacDonald, an undergraduate, and Darin Ragozzine, an assistant professor of physics and space sciences, both at Florida Institute of Technology, led the study. The unusual planetary array deepens the ongoing examination of similar systems known as STIPs (Systems … Continue reading Understanding Synchronized Orbits of Exoplanets in Kepler-80
Eirsat-1, the first fully Irish-designed satellite, was built by UCD staff and students as part of an educational programme by the European Space Agency. It is set to fall out of orbit this week and disintegrate in the atmosphere, marking the culmination of a pioneering UCD-led project that has nurtured a generation of home-grown space … Continue reading UCD’s Eirsat-1: Transforming Irish Space Science
The fluid, which defies everyday laws of motion, is a rare achievement and provides a platform to study an otherwise hypothetical form of matter. Scientists have created a fluid that exhibits the bizarre property of “negative mass” in an experiment that appears to defy the everyday laws of motion. Push an object, and Newton’s laws … Continue reading 🧪 Scientists Create a Fluid with Negative Mass: A Discovery That Could Rewrite Physics 🚀
Most large galaxies are thought to harbour supermassive black holes in their central regions. These enormous gravitational powerhouses can weigh anything from a few hundred thousand to several billion times the mass of a normal star. In some galaxies, such as our own Milky Way, these black holes may be dormant. But in active galaxies … Continue reading 🌌 Is the Milky Way’s Supermassive Black Hole Shaping the Universe’s Most Powerful Cosmic Rays? 🕳️⚡
A snappy little post today, the science behind the spectacular display of the Aurora Borealis, a.k.a Northern Lights. This mystical display of colours may be better left to childhood imagination, but in the name of science, we shall explain its true origin. As with many things here on Earth, the existence of the Northern Lights … Continue reading 🌌 The Hidden Mystery Behind the Mesmerising Northern Lights ✨
Since Vera Rubin's pioneering work on galactic rotation, the term Dark Matter has intrigued many people. Something else that often accompanies this term is Dark Energy. Both sound mysterious, and it's easy to imagine them as sinister forces, I did. But then I learned Dark simply implied that it doesn’t interact with light.
