Are Neutrinos Their Own Evil Twins? Part 4: Majorana’s Mystery
(This is Part 4 of a series on neutrinos, Majorana fermions, and one of the strangest open questions in physics. Read Part 1, Part 2, and Part 3.) It’s 1937. One year before Ettore Majorana vanishes. He is sitting with Dirac’s framework — the precise, picture-perfect vision of quantum mechanics — and doing what very

Exploring the Moon’s Shadowy Craters With Nuclear-Powered Rovers
NASA and other space agencies are intent on sending astronauts back to the Moon, and this time, to stay! A vital part of these plans for reducing costs and dependency on Earth is the process of In-Situ Resource Utilization (ISRU), using local resources for construction materials and meeting astronauts’ basic needs. This is why the

The Incredible Shrinking Neutrino. – Universe Today
They pass through you at a rate of around a hundred trillion every second, that’s about 12 quadrillion while you read this article, depending on how fast you read of course! You won’t feel a thing though since neutrinos are so reluctant to interact with ordinary matter that the entire Earth, and you too, are

Reading the Moon’s Buried Past.
The lunar south pole looks chaotic from orbit. Craters heaped upon craters, ancient basins, scarps and slopes tumbling in every direction, it is without doubt, one of the most geologically complicated terrains in the inner Solar System. That aside, it’s exactly where we intend to send people since understanding what lies beneath that battered surface

The Universe’s Most Powerful Telescope.
SN 2025mkn is a Type II supernova and it wasn’t supposed to be visible at all. The violent death of a massive star that had exhausted its nuclear fuel and collapsed under its own gravity sits at a redshift of 1.371. That places it roughly nine billion light years away. At that distance, an ordinary

The Zhamanshin Impact Event Was Likely Much More Destructive Than Thought
Earth and the course of life on Earth have been shaped by impacts. Scientists have uncovered links between massive impacts and changes in climate that altered the planet forever. But the further scientists look into the past to try to understand these changes, the more difficult it is to link them together. Impact craters don’t

Are Neutrinos Their Own Evil Twins? Part 3: Dirac’s Direct Solution
(This is Part 3 of a series on neutrinos, Majorana fermions, and one of the strangest open questions in physics. Read Part 1 and Part 2.) Neutrinos have mass. We know this. And massive particles — ALL massive particles, as we established in Part 1 — flicker between left- and right-handed states. That flickering IS

Exoplanet Host Star Shares Elemental Traits with Its Hot Jupiter
An ultra-hot Jupiter exoplanet orbiting a young A-type star gave scientists using the Gemini South telescope a look at how both a star and its hot planet can have similar chemical compositions. The team, led by Arizona State University graduate student Jorge Antonio Sanchez, took spectra of the planet, called WASP-189b, using the Immersion Grating

Saturn’s Magnetic Shield Is Not Where Anyone Expected It To Be.
Even a modest telescope reveals the breathtaking Saturnian ring system that has captivated astronomers for four centuries, a world so alien in its beauty that first time observers often struggle to believe what they are seeing is real. But Saturn’s rings are just the beginning. Beneath that iconic silhouette lies a planet of extraordinary extremes,

The Most Quiet Place We’ve Ever Listened From!
We have been searching for signals from other civilisations for over sixty years. Radio telescopes on Earth have swept the sky, listened patiently, and found nothing but silence. It is a search that demands extraordinary sensitivity and that is the problem, Earth and our very existence itself is getting in the way. Every mobile phone,
