Scientists fear that microorganisms from Mars might spread to Earth, yet substantial natural material from it falls to our planet, including signs of life. Perseverance rover is exploring rocks formed from an ancient lake at Jezero Crater in Arizona, searching for signs of microorganisms and carbon-containing organic molecules. Unfortunately, Perseverance’s instruments cannot guarantee success 100%…
Scientists have recently discovered an exoplanet which lies closer to Earth than ever before – within just four light-years and within its star’s habitable zone, where liquid water could potentially exist on its surface. Planet 95% the size of our own Earth would likely be composed of rocks and soil; it likely orbits a red…
Last week, scientists announced the discovery of an Earth-like planet orbiting Proxima Centauri — our closest star and source of life — which might support life. This exoplanet represents one of the nearest possible candidate planets for human habitation ever found so far. But how close are we cosmically speaking? To answer that question, we…
Astronomers have discovered a planet the size of Earth which orbits its host star within the habitable zone – meaning its surface could support liquid water life. Astronomers in search of alien life will take heart in this discovery, which indicates that rocky planets are far more widespread than previously assumed. Kepler-1649c Astronomers using data…
NASA’s car-sized Curiosity rover is searching the Jezero Crater on Mars for signs that once supported life. Engineers write commands giving Curiosity an up-close 3D view of hazards such as large rocks and steep slopes. But when a spaceship crash lands on another world, debris from its landing often scatters everywhere – one piece even…
