Iron winds detected on ultra-hot exoplanet WASP-76 b
An international group of astronomers, including researchers from the University of Geneva (UNIGE) and the PlanetS National Centre of Competence in Research, has uncovered the presence of iron winds in the atmosphere of the ultra-hot Jupiter, WASP-76 b. This planet, with temperatures soaring beyond 2000 degrees Celsius, has been a focal point for scientists as they explore the extreme atmospheri
How bright is the universe's glow? Study offers best measurement yet
Scientists have traveled to the edges of the solar system, virtually, at least, to capture the most accurate measurements to date of the faint glow that permeates the universe-a phenomenon known as the cosmic optical background. The new study, published Aug. 28 in The Astrophysical Journal, draws on observations from NASA's New Horizons spacecraft, which whizzed past Pluto in 2015 and is n
BepiColombo completes fourth Mercury flyby
The ESA/JAXA BepiColombo mission successfully carried out its fourth of six gravity assist flybys at Mercury, capturing critical data and views of two distinct impact craters. These flybys utilize Mercury's gravity to steer the spacecraft for its final arrival in orbit around the planet in November 2026. The closest approach occurred on 4 September 2024 at 23:48 CEST (21:48 UTC), with Bepi

Debris from DART impact could reach Earth
In 2022 NASA’s DART spacecraft made history, and changed the Solar System forever, by impacting the Dimorphos asteroid and measurably shifting its orbit around the larger Didymos asteroid. In the process a plume of debris was thrown out into space.
The latest modelling, available on the preprint server arXiv and accepted for publication in the September volume of The Planetary Science Journal, shows how small meteoroids from that debris could eventually reach both Mars and Earth – potentially in an observable (although quite safe) manner.
Mars rover trials
Rover trials in a quarry in the UK showing a four-wheeled rover, known as Codi, using its robotic arm and a powerful computer vision system to pick up sample tubes.
The rover drives to the samples with an accuracy of 10cm, constantly mapping the terrain. Codi uses its arm and four cameras to locate the sample tube, retrieve it and safely store it on the rover – all of it without human intervention. At every stop, the rover uses stereo cameras to build up a 180-degree map of the surroundings and plan its next maneouvres. Once parked, the camera
Gigantic asteroid impact shifted the axis of Solar System's biggest moon
Around 4 billion years ago, an asteroid struck Ganymede, Jupiter's largest moon, leading to a significant shift in its axis. A researcher from Kobe University has recently confirmed that this impact was caused by an asteroid approximately 20 times larger than the one responsible for the extinction event that ended the age of the dinosaurs on Earth, making it one of the most significant impacts w
Researchers confirm volcanic activity on the Moon 120 million years ago
Geological evidence has long shown that volcanic activity occurred on the Moon, but the duration of this activity has remained uncertain. A recent discovery by Prof. LI Qiuli's lab at the Institute of Geology and Geophysics, Chinese Academy of Sciences (IGGCAS), has provided new insights into the Moon's volcanic history. The team identified three volcanic glass beads from lunar soil samples coll
Small asteroid creates 'spectacular fireball' while burning up over Philippines
A small asteroid burned up after it entered the Earth's atmosphere Wednesday afternoon over the Philippines. It did not cause any harm to humans or infrastructure. The European Space Agency discovered the small asteroid early Wednesday and said it would enter the atmosphere at 12:46 p.m. EDT over the western Pacific Ocean near the Philippines' island of Luzon.

Hubble and MAVEN collaborate to uncover Mars' water loss
Mars, once a planet with abundant water, now presents a mystery regarding the fate of its water resources. While scientists believe some water may have gone underground over the past 3 billion years, a significant amount has escaped. NASA's Hubble Space Telescope and the Mars Atmosphere and Volatile Evolution (MAVEN) mission are now shedding light on this longstanding mystery. "There are o
