Which planet has the most moons? Moons of Saturn, Venus and Jupiter explained
This great big solar system has plenty of secrets to tell. Just recently, NASA's new James Webb Telescope dazzled us mere Earthlings with the first images released to date of galaxies eons in the past......»»
NASA"s mission to an ice-covered moon will contain a message between water worlds
NASA's Europa Clipper spacecraft, headed to Jupiter's ice-covered moon Europa in October 2024, will carry a laser-etched message that celebrates humanity's connection to water. The message pays homage to past NASA missions that carried similar messag.....»»
In a distant stellar system, the JWST sees the end of planet formation
Every time a star forms, it represents an explosion of possibilities. Not for the star itself; its fate is governed by its mass. The possibilities it signifies are in the planets that form around it. Will some be rocky? Will they be in the habitable.....»»
Life might be difficult to find on a single planet but may be obvious across many worlds
If we could detect a clear, unambiguous biosignature on just one of the thousands of exoplanets we know of, it would be a huge, game-changing moment for humanity. But it's extremely difficult. We simply aren't in a place where we can be certain that.....»»
NASA"s Europa clipper survives and thrives in "outer space on Earth"
In less than six months, NASA is set to launch Europa Clipper on a 1.6-billion-mile (2.6-billion-kilometer) voyage to Jupiter's ocean moon Europa. From the wild vibrations of the rocket ride to the intense heat and cold of space to the punishing radi.....»»

Saturn"s moon Enceladus top target for ESA
A fresh, icy crust hides a deep, enigmatic ocean. Plumes of water burst through cracks in the ice, shooting into space. An intrepid lander collects samples and analyzes them for hints of life......»»
Antarctic sea ice near historic lows: Arctic ice continues decline
Sea ice at both the top and bottom of the planet continued its decline in 2024. In the waters around Antarctica, ice coverage shrank to near-historic lows for the third year in a row. The recurring loss hints at a long-term shift in conditions in the.....»»
Planet cannibalism is common, says cosmic "twin study"
How stable are planetary systems? Will Earth and its seven siblings always continue in their steady celestial paths, or might we one day be randomly ejected from our cosmic home?.....»»
Signs of life detectable in single ice grain emitted from extraterrestrial moons, experimental setup shows
The ice-encrusted oceans of some of the moons orbiting Saturn and Jupiter are leading candidates in the search for extraterrestrial life. A new lab-based study led by the University of Washington in Seattle and the Freie Universität Berlin shows tha.....»»
Water persisted in Mars" Gale crater for longer than previously thought, study finds
Billions of years ago, Mars was home to abundant water, and its Gale crater contained a lake. Gradually, the climate changed, drying the red planet and creating the dusty desert world we know today......»»

The Mars science helicopter could be an airborne geologist on Mars
After more than 70 successful flights, a broken rotor ended the remarkable and groundbreaking Ingenuity helicopter mission on Mars. Now, NASA is considering how a larger, more capable helicopter could be an airborne geologist on the Red Planet. For t.....»»
One impact on Mars produced more than 2 billion secondary craters, finds study
There are plenty of craters on Mars, especially when compared to Earth. That is primarily thanks to the lack of weathering forces and strong plate tectonics that disrupt the formations of such impacts on our home planet. However, not all impact crate.....»»

Life"s building blocks are surprisingly stable in Venus-like conditions: Study
If there is life in the solar system beyond Earth, it might be found in the clouds of Venus. In contrast to the planet's blisteringly inhospitable surface, Venus' cloud layer, which extends from 30 to 40 miles above the surface, hosts milder temperat.....»»
Webb finds hints of a third planet at PDS 70
The exoplanet census now stands at 5,599 confirmed discoveries in 4,163 star systems, with another 10,157 candidates awaiting confirmation. So far, the vast majority of these have been detected using indirect methods, including transit photometry (74.....»»
NASA delivers science instrument to JAXA"s Martian Moons mission
On March 14, NASA handed over its gamma-ray and neutron spectrometer instrument to JAXA (Japan Aerospace Exploration Agency) for integration onto JAXA's MMX (Martian Moons eXploration) mission spacecraft and final system-level testing......»»
Planet "on the brink", with new heat records likely in 2024: UN
Global temperatures "smashed" heat records last year, as heat waves stalked oceans and glaciers suffered record ice loss, the United Nations said Tuesday—warning 2024 was likely to be even hotter......»»
Study highlights achievements of the scientific drilling of Songliao Basin
Since the dawn of the Industrial Revolution, the increase in carbon dioxide emissions has consistently warmed the Earth's climate. At the current warming rate, our planet might potentially be on track toward witnessing a greenhouse climate state with.....»»
