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?

Long-term radio observations probe a relativistic binary pulsar system

Astronomers have analyzed the data from long-term radio observations of a binary pulsar known as PSR J1906+0746. Results of the new study, published February 5 on the arXiv pre-print server, deliver important information regarding the nature of this system.

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.

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 […]

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.

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 […]

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.

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 […]

Study outlines how JWST and Ariel could team up on exoplanet atmospheres

Astronomers want to collect as much data as possible using as many systems as possible. Sometimes that requires coordination between instruments. The teams that run the James Webb Space Telescope (JWST) and the upcoming Atmospheric Remote-sensing Infrared Exoplanet Large-survey (Ariel) missions will have plenty of opportunity for that once both telescopes are online in the […]

Strong correlations and superconductivity observed in a supermoiré lattice

Two or more graphene layers that are stacked with a small twist angle in relation to each other form a so-called moiré lattice. This characteristic pattern influences the movement of electrons inside materials, which can give rise to strongly correlated states, such as superconductivity.

How a certain form of dark matter may lead to the generation of cosmological magnetic fields

Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, however, the physical mechanisms underpinning the generation of these fields remain poorly understood. Recently, researchers at McGill University and ETH Zurich have described a novel mechanism that may lead to the generation of cosmological magnetic fields. This mechanism, […]

The Hubble tension: How magnetic fields could help solve one of the universe’s biggest mysteries

It’s well established that the universe is expanding, but there’s serious disagreement among scientists over how fast it’s happening.
