A landmark discovery by a collaborative team led by the Planetary Science Institute's Alexis Rodriguez has unveiled evidence of sedimentary plains created by aquifer drainage within Martian collapse formations termed chaotic terrains. "Our research focuses on a sedimentary unit within Hydraotes Chaos, which we interpret to be the remnants of a mud lake formed by discharges from gas-charged

An advanced new three-dimensional (3D) computer simulation of the light emitted following a merger of two neutron stars has produced a similar sequence of spectroscopic features to an observed kilonova. "The unprecedented agreement between our simulations and the observation of kilonova AT2017gfo indicates that we understand broadly what has taken place in the explosion and aftermath," say

Astronomers have created a detailed atlas of almost 400,000 galaxies in our cosmic neighborhood. The Siena Galaxy Atlas was compiled using data from NSF's NOIRLab telescopes, and is designed to be the pre-eminent digital galaxy atlas for large galaxies. It's a treasure trove of information for researchers investigating everything from galaxy formation and evolution to dark matter and gravitation

Large swings in past ocean oxygen revealed

As the climate warms, there is major concern that Earth's ocean will lose oxygen. A study published recently by oceanographers at the University of Hawai'i at Manoa revealed that locked in ancient deep-sea sediments is evidence for oxygen loss in the world's ocean during past glacial periods, indicating that widespread oxygen loss with current climate change may not be permanent.

NASA conducted the first hot fire of a new RS-25 test series Oct. 17, beginning the final round of certification testing ahead of production of an updated set of the engines for the SLS (Space Launch System) rocket. The engines will help power future Artemis missions to the Moon and beyond. Operators fired the RS-25 engine for more than nine minutes (550 seconds), longer than the 500 secon

A new paper entitled "Evolutionary Paths of Active Galactic Nuclei and Their Host Galaxies," published on August 17, 2023, in Nature Astronomy, provides critical new insights on the co-evolution of supermassive black holes and their host galaxies. The research, conducted by Dr. Ming-Yang Zhuang, who graduated from Peking University in 2022 and is currently affiliated with the University of

The analysis of ancient, superdeep diamonds dug up from mines in Brazil and Western Africa, has exposed new processes of how continents evolved and moved during the early evolution of complex life on Earth. These diamonds that were formed between 650 and 450 million years ago on the base of the supercontinent Gondwana, were analysed by an international team of experts, and have shown how s

High-speed internet access that delivers video streaming, gaming, and virtual and augmented-reality content via satellites to people living and travelling in remote areas has come a step closer.

The scene was set: a research base on the Red Planet was struck by a cyberattack and eight teams on Earth had just a matter of hours to save it. Far from being a farfetched scenario, cyberattacks are unfortunately a daily problem for all sectors, including space exploration, and can have devastating consequences.

The ‘Pwn The Rover’ hacking contest was held on 17 October at ESA’s mission control centre in Darmstadt, Germany, in collaboration with Fraunhofer SIT and ATHENE-Center. Its goal was to bring together, educate

How NASA's Europa Clipper will survive its trip to Jupiter's hostile moon

If life exists elsewhere in the solar system, it may well reside in the ocean of Jupiter's icy moon Europa.

The mysterious world appears to have the necessary ingredients for life as we know it. Beneath its frozen exterior is a single body of water that's so deep it may hold more liquid than all of the oceans on Earth. Europa is believed to have enough carbon, hydrogen, nitrogen, oxygen and other key elements to form the building blocks of living organisms. And scientists suspect the heat generated as the moon is stretched and squeezed by Jupiter's gravity would provide enough energy to sustain any creatures that might be there.

That's why NASA is building Europa Clipper.

The spacecraft will blast off from the Kennedy Space Center in Florida a year from now and reach its destination in 2030.
