A new analysis of data collected on Venus more than 30 years ago suggests the planet may currently be volcanically active.

A research group from Italy led by David Sulcanese of the Università d’Annunzio in Pescara, Italy, has used data from a radar mapping of Venus’s surface taken in the early 1990s to search for volcanic lava flow, finding it in two regions.

The discovery suggests that volcanic activity may be currently active and more widespread than was previously thought, supporting previous indirect evidence that there is volcanic activity on Venus.

Studying pulsing Cepheid stars offers a cosmic yardstick by which to measure the universe.

A recent study has investigated teleparallel gravity and its potential to resolve tension surrounding the expansion of the universe in a way that general relativity can’t.

Researchers discovered four mini-Neptunes with volatile-rich compositions around red dwarfs, using both space and ground-based telescopes. Researchers discovered mini-Neptunes[1] around four red dwarfs[2], which are named TOI-782, TOI-1448, TOI-2120, and TOI-2406, using observations from a glob.

A team from Nagoya University invented a heat-switch device for lunar rovers to withstand the Moon’s extreme temperatures. The technology optimizes thermal control, alternating between cooling and insulating, facilitating longer missions with less energy.

Astronauts navigating the moon’s terrain in a vehicle contend with not only the perils of zero gravity and potential crater falls, but also drastic temperature swings. The moon’s climate ranges from searing highs of 127°C (260°F) to bone-chilling lows of −173°C (−280°F).

Team from Nagoya University in Japan developed a heat-switch device designed to enhance the durability of lunar rovers. Their collaborative research with the Japan Aerospace Exploration Agency was featured in the journal Applied Thermal Engineering.

Scientists found that water in our solar system is likely billions of years older than the sun by studying the protostar V883 Orion, linking water from the interstellar medium to our solar system.

This research suggests that water in our solar system was formed long before the sun, planets, and comets, indicating that planetary systems.

A bioresorbable, wireless hydrogel (metagel) sensor, encompassing both biodegradable and stimulus-responsive hydrogels for ultrasonic monitoring of intracranial signals, was implanted into intracranial space with a puncture needle and deformed in response to physiological environmental changes.
