Using ESO's Very Large Telescope (VLT), two teams of astronomers have observed the aftermath of the collision between NASA's Double Asteroid Redirection Test (DART) spacecraft and the asteroid Dimorphos. The controlled impact was a test of planetary defence, but also gave astronomers a unique opportunity to learn more about the asteroid's composition from the expelled material.

Research in languages other than English is critically important for biodiversity conservation and is shockingly under-utilized internationally, according to an international research team.

Fewer parasites in U.S. waters might be seen by many as a good thing, but a biologist says the trend signals potential danger for fish and other wildlife.

A new study explores a record of birds' diets preserved in their feathers and radio tracking of their movements to find that birds eat far fewer invertebrates in coffee plantations than in forests, suggesting that the disturbance of their ecosystem significantly impacts the birds' dietary options.

Intense fishing and over-exploitation have led to evolutionary changes in fish stocks like cod, reducing both their productivity and value on the market. These changes can be reversed by more sustainable and far-sighted fisheries management. A new study shows that reversal of evolutionary change would only slightly reduce the profit of fishing, but would help regain and conserve natural genetic diversity.

There's been a well-documented shift toward earlier springtime flowering in many plants as the world warms. The trend alarms biologists because it has the potential to disrupt carefully choreographed interactions between plants and the creatures -- butterflies, bees, birds, bats and others -- that pollinate them.

Venus appears to have volcanic activity, according to a new research paper that offers strong evidence to answer the lingering question about whether Earth's sister planet currently has eruptions and lava flows.

Scientists revealed the discovery of a relict glacier near Mars' equator. Located in Eastern Noctis Labyrinthus at coordinates 7° 33' S, 93° 14' W, this finding is significant as it implies the presence of surface water ice on Mars in recent times, even near the equator. This discovery raises the possibility that ice may still exist at shallow depths in the area, which could have significant implications for future human exploration.

A new study brings scientists one step closer to answering the question of where Earth's water came from.

Populations of whooper swans grow 30 times faster inside nature reserves, new research shows.

Dramatic differences between shallow and mesophotic reefs stress the importance of studying--and conserving--these vital ecosystems along their entire depth gradient.

An analysis extending from southern Portugal to northern Norway highlights the importance of temperature in determining where fish species are found.

As almost 200 countries agree a legally-binding treaty to protect the High Seas, a collaboration of experts in ocean plastic pollution and satellite technology has urged world leaders to learn lessons from the management of the High Seas and act now to protect Earth's orbit.

Observations of water in the disk forming around protostar V883 Ori have unlocked clues about the formation of comets and planetesimals in our own solar system.

Research into the ability of a wildfire to improve the health of a forest uncovered a Goldilocks effect -- unless a blaze falls in a narrow severity range, neither too hot nor too cold, it isn't very good at helping forest landscapes return to their historical, more fire-tolerant conditions.

A research team has shed new light on the importance of plant roots for below-ground life, particularly in the tropics. Millions of small creatures toiling in a single hectare of soil including earthworms, springtails, mites, insects, and other arthropods are crucial for decomposition and soil health. For a long time, it was believed that leaf litter is the primary resource for these animals. However, this recent study is the first to provide proof that resources derived from plant roots drive soil animal communities in the tropics.

A terrestrial planet hovering between Mars and Jupiter would be able to push Earth out of the solar system and wipe out life on this planet, according to a recent experiment.

Researchers have developed an algorithm that uses computer vision techniques to accurately measure trees almost five times faster than traditional, manual methods.

When asteroids suffer natural impacts in space, debris flies off from the point of impact. The tail of particles that form can help determine the physical characteristics of the asteroid. NASA's Double Asteroid Redirection Test mission in September 2022 gave a team of scientists a unique opportunity -- to observe the evolution of an asteroid's ejecta as it happened.

Future space missions likely will send robots to scout out underground habitats for astronauts. Engineers have now developed a system that would enable autonomous vehicles to explore caves, lava tubes and even oceans on other worlds on their own.
