What cold-water geysers on Earth reveal about the habitability of ocean worlds

In the eastern Utah desert, carbon-dioxide-saturated water bubbles, sprays and foams from the ground. These cold-water geysers, sometimes called soda pop geysers, are a new and reliable Earth-based analog for scientists studying plume eruptions of ocean worlds in the outer solar system, according to new research led by Planetary Science Institute Senior Scientist Morgan Cable and published in Astrobiology.

Silicon quantum processor detects single-qubit errors while preserving entanglement

Quantum computers are alternative computing devices that process information, leveraging quantum mechanical effects, such as entanglement between different particles. Entanglement establishes a link between particles that allows them to share states in such a way that measuring one particle instantly affects the others, irrespective of the distance between them.

Optical switch protocol verifies entangled quantum states in real time without destroying them

The fragility and laws of quantum physics generally make the characterization of quantum systems time‑consuming. Furthermore, when a quantum system is measured, it is destroyed in the process. A breakthrough by researchers at the University of Vienna demonstrates a novel method for quantum state certification that efficiently verifies entangled quantum states in real time without destroying all available states—a decisive step forward in the development of robust quantum computers and quantum networks.

If alien signals have already reached Earth, why haven’t we seen them?

For decades, scientists have searched the skies for signs of extraterrestrial technology. A study from EPFL asks a sharp question: if alien signals have already reached Earth without us noticing, what should we realistically expect to detect today?

Early Mars was warm and wet not icy, suggests latest research

A recent study showed that Mars was warm and wet billions of years ago. The finding contrasts with another theory that this era was mainly cold and icy. The result has implications for the idea that life could have developed on the planet at this time.

A new concept for catching up with 3I/ATLAS

The arrival of 3I/ATLAS in our solar system spawned multiple proposals for a rendezvous mission to study it up close. As the third interstellar object (ISO) ever detected, the wealth of information direct studies could provide would be groundbreaking in many respects. However, the mission architecture for intercepting an interstellar comet poses numerous significant challenges for mission designers and planners. Chief among them is the technological readiness level (TRL) of the proposed propulsion systems, ranging from conventional rockets to directed-energy propulsion (DEP).

Using light to probe fractional charges in a fractional Chern insulator

In some quantum materials, which are materials governed by quantum mechanical effects, interactions between charged particles (i.e., electrons) can prompt the creation of quasiparticles called anyons, which carry only a fraction of an electron’s charge (i.e., fractional charge) and fractional quantum statistics.
