One of the longest-standing techniques in humanity’s search for life beyond Earth may be causing scientists to miss alien ...

Astronomers have discovered a unique planet in the Milky Way's Volans constellation, featuring a molten surface and sulfur-rich atmosphere. This hellish world, over 60% larger than Earth but less ...

The molten planet, with an atmosphere rich in sulfur-bearing gases, is unlike anything astronomers have ever smelled.

SETI researchers may have missed alien signals due to a cosmic phenomenon that distorts narrowband radio waves, new research says.

For four decades, many SETI experiments have focused on finding sharp spikes in frequency but the new study says signals may not stay narrow as they travel away from their home system.

Many of the most damaging invasions do not simply subtract species; they fundamentally remodel the environment, altering habitats, rewiring interactions, and shifting processes in ways that species ...

Invasive species that are introduced into non-native environments threaten ecosystems, wildlife, and human well-being.

Invasive alien species don’t only drive out other native species, they also dramatically transform soils, water and ecosystems. A new assessment tool aims to pinpoint the negative environmental ...

Many people who don’t believe one conspiracy theory about that station—known as the High-frequency Active Auroral Research ...

Radio silence has long puzzled those searching for extraterrestrial intelligence, but the answer might lie much closer to the source of potential signals than previously thought. Conditions around ...

The alien-like machines, described as ‘legged metamachines’, are built from autonomous modules that can be snapped together in a variety of forms. Researchers say the approach could lead to robots ...

More than 40% of extant large freshwater animals (megafauna), including carp, salmonids, crocodilians, turtles, beavers, and ...
