Team maps moon's surface for NASA missions
Team maps moon’s surface for NASA missions
UCL researchers are helping NASA prepare for its Artemis programme moon missions by creating high-resolution 3D models of potential landing sites. The first phase of NASA's Artemis mission, an uncrewed test flight around the moon, was scheduled to launch this Monday (29 August 2022). The third phase, scheduled for 2025, will see humans land on the moon for the first time in more than 50 years.

Planet Mars: Perseverance rover makes surprising geological discoveries in Jezero Crater
Planet Mars: Perseverance rover makes surprising geological discoveries in Jezero Crater
On February 21, 2021, NASA's Perseverance rover landed in the Jezero Crater on Mars. In October 1 , the rover confirmed the importance of its landing site, showing that Jezero Crater really was the site of a lake 3.6 billion years ago. Perseverance's geological discoveries in the crater's floor are described in four papers published on August 25, 2022 in Science and Science Advances .

James-Webb detects carbon dioxide in exoplanet atmosphere
The new space telescope has revealed the presence of carbon dioxide on the gas giant WASP-39b. A first in which the UNIGE and UNIBE participated. Launched at the end of 2021 by NASA, with the collaboration of the European Space Agency (ESA) and the Canadian Space Agency (CSA), the James-Webb Space Telescope has delivered an exceptional first scientific result: for the first time, CO2 has been clearly detected in the atmosphere of WASP-39b, a planet located outside the solar system.

Perseverance rover retrieves key clues to Mars’ geologic and water history
The Perseverance Mars rover took this selfie on Sept. 10, 2021 - sol 198 of the mission – in Jezero Crater after coring into a rock called 'Rochette.' Rock core samples from the floor of the crater will be brought back to Earth and analyzed to characterize the planet's geology and past climate.

An extrasolar world covered in water?
An extrasolar world covered in water?
With the help of instruments designed partly in Canada, a team of Université de Montréal astronomers have discovered an exoplanet that could be completely covered in water. An international team of researchers led by Charles Cadieux, a Ph.D. candidate at the Université de Montréal and member of the Institute for Research on Exoplanets (iREx), has announced the discovery of TOI-1452 b, an exoplanet orbiting one of two small stars in a binary system located in the Draco constellation about 100 light-years from Earth.

Comet impacts formed continents when Solar System entered galactic arms
New Curtin research has found evidence that Earth's early continents resulted from being hit by comets as our Solar System passed into and out of the spiral arms of the Milky Way Galaxy, turning traditional thinking about our planet's formation on its head. The new research, published in Geology , challenges the existing theory that Earth's crust was solely formed by processes inside our planet, casting a new light on the formative history of Earth and our place in the cosmos.

The photon ring: a black hole ready for its close-up
Scientists have discerned a sharp ring of light created by photons whipping around the back of a supermassive black hole in a vivid confirmation of theoretical prediction When scientists unveiled humanity's historic first image of a black hole in 2019 - depicting a dark core encircled by a fiery aura of material falling toward it - they believed even richer imagery and insights were waiting to be teased out of the data.

Brightest stars in the night sky can strip planets to their rocky cores
Artist's concept of a Neptune-sized planet, left, around a blue, A-type star. UC Berkeley astronomers have discovered a hard-to-find gas giant around one of these bright, but short-lived, stars, right at the edge of the hot Neptune desert where the star's strong radiation likely strips any giant planet of its gas.

One more clue to the Moon's origin
One more clue to the Moon’s origin
Researchers from ETH Zurich discover the first definitive proof that the Moon inherited indigenous noble gases from the Earth's mantle. The discovery represents a significant piece of the puzzle towards understanding how the Moon and, potentially, the Earth and other celestial bodies were formed. Humankind has maintained an enduring fascination with the Moon.

Astrophysicist helps map the origins of the universe
No bigger than a microwave oven, a device designed and built by a University of Miami astrophysicist is helping an international team of astronomers obtain a colossal amount of data on how the universe's so-called dark ages came to an end roughly 400 million years after the Big Bang. Josh Gundersen's 125-pound cryostat, which he partially fabricated at the University's Coral Gables Campus, cools the receiver array of a high-tech radio telescope to 15 degrees above absolute zero, ensuring that the dish will be able to pick up light emitted by galaxies billions of years ago.

No trace of dark matter halos
No trace of dark matter halos
Signs of disturbance in the dwarf galaxies of one of Earth's nearest galaxy clusters indicate an alternative gravity theory According to the standard model of cosmology, the vast majority of galaxies are surrounded by a halo of dark matter particles. This halo is invisible, but its mass exerts a strong gravitational pull on galaxies in the vicinity.
