  • Astronomers use Earth’s history as guide to spot vegetation on new worlds

    Sep 25, 2018
    By looking at Earth’s full natural history and evolution, astronomers may have found a template for vegetation fingerprints – borrowing from epochs of changing flora – to determine the age of habitable exoplanets. “Our models show that Earth’s vegetation reflectance signature increases with coverage of

  • Martian moon may have come from impact on home planet, new study suggests

    Sep 24, 2018
    The weird shapes and colors of the tiny Martian moons Phobos and Deimos have inspired a long-standing debate about their origins. The dark faces of the moons resemble the primitive asteroids of the outer solar system, suggesting the moons might be asteroids caught long ago

  • Scientists ID Three Causes of Earth’s Spin Axis Drift

    Sep 24, 2018
    A typical desk globe is designed to be a geometric sphere and to rotate smoothly when you spin it. Our actual planet is far less perfect — in both shape and in rotation. Earth is not a perfect sphere. When it rotates on its spin

  • Ancient Mars had right conditions for underground life, new research suggests

    Sep 24, 2018
    A new study shows evidence that ancient Mars probably had an ample supply of chemical energy for microbes to thrive underground. “We showed, based on basic physics and chemistry calculations, that the ancient Martian subsurface likely had enough dissolved hydrogen to power a global subsurface

  • NASA’s MAVEN Selfie Marks Four Years in Orbit at Mars

    Sep 23, 2018
    NASA’s MAVEN spacecraft celebrates four years in orbit studying the upper atmosphere of the Red Planet and how it interacts with the Sun and the solar wind. To mark the occasion, the team has released a selfie image of the spacecraft at Mars. “MAVEN has been

  • Recent Tectonics on Mars

    Sep 23, 2018
    These prominent trenches were formed by faults that pulled the planet’s surface apart less than 10 million years ago. The images were taken by ESA’s Mars Express on 27 January, and capture part of the Cerberus Fossae system in the Elysium Planitia region near the

  • Fat from 558 million years ago reveals earliest known animal

    Sep 22, 2018
    Scientists from The Australian National University (ANU) and overseas have discovered molecules of fat in an ancient fossil to reveal the earliest confirmed animal in the geological record that lived on Earth 558 million years ago. The strange creature called Dickinsonia, which grew up to

  • Astrophysicists measure precise rotation pattern of sun-like stars for the first time

    Sep 22, 2018
    Sun-like stars rotate up to two and a half times faster at the equator than at higher latitudes, a finding by researchers at NYU Abu Dhabi that challenges current science on how stars rotate. Until now, little was known about the precise rotational patterns of

  • Candy-pink lagoon serves up salt-rich diet for potential life on Mars

    Sep 21, 2018
    The discovery of a microorganism that gives a candy-pink lagoon in central Spain its startling colour is providing new evidence for how life could survive on a high-salt diet on Mars or Europa. The Laguna de Peña Hueca, part of the Lake Tirez system in
