New tool could reduce collision risk for Earth-observation satellites

Researchers at The University of Manchester have developed a new way to design Earth-observation satellite missions that could help protect the space environment while continuing to deliver vital data for tackling global challenges, such as climate change, food production, supply chain vulnerabilities and environmental degradation.

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 […]

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 […]

Southern California sky is lit up by Valentine’s Day SpaceX launch

Southern Californians out on Saturday night for Valentine’s Day took a break from staring longingly into each other’s eyes to gaze at something else: a SpaceX rocket blazing across the early evening Southern California sky.

NASA to let private company Vast visit space station for private mission in 2027

NASA has let Axiom Space make four visits to the International Space Station and in January 2026 awarded it the right for the fifth visit next year, but on Feb. 12, the agency announced a new company would be allowed a private mission as well.

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.

Physicists explain the exceptional energy-harvesting efficiency of perovskites

Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at converting solar energy into electricity. Their efficiency is approaching that of silicon-based solar cells, the industry standard. In a new study published in Nature Communications, physicists at the Institute of Science and Technology Austria (ISTA) present a comprehensive explanation of the […]

Massive Lava Tubes on Mars and the Moon Could Shelter Astronauts

Lava tubes on Mars could provide shelter for astronauts, according to a new study. Earlier studies have suggested the same could apply to the Moon.

An Army Intelligence Officer and Combat Veteran turned Ufologist and Astrophysicist, Antonio Paris, and other researchers have published a study suggesting astronauts could live in relative safety underground on […]

The balloon mission raising the bar for exoplanet science

The atmospheres of exoplanets have been a focal point of the field lately, with the James Webb Space Telescope taking a look at as many as it can manage. But time on the world’s most powerful space telescope is valuable, and getting a complete picture of any such atmosphere is difficult without that significant time […]

German Cave Reveals Clues About the First Domesticated Wolves

Scientists have found new important clues about the first domesticated wolves and dogs.

A small cave in Germany contained numerous ancient canine fossils. They could point to a possible origin of all modern dogs. However, researchers stress this remains open to debate and further evidence.

Dogs are considered the oldest […]
