Dec 9, 2019 · Saturn’s icy moon Enceladus is of great interest to scientists due to its subsurface ocean, making it a prime target for those searching for life elsewhere. New research led by Carnegie’s Doug Hemingway reveals the physics governing the fissures through which oceanwater erupts from the moon’s icy surface, giving its south pole an unusual ...

Nov 1, 2018 · The stars from this partner, named Gaia-Enceladus, make up most of the Milky Way’s halo and also shaped its thick disk, giving it its inflated form. A description of this mega-merger, discovered by an international team led by University of Groningen astronomer Amina Helmi, is now published in the scientific journal Nature.

Jan 17, 2012 · By analyzing protein folds from organisms representing every domain of life, a team of scientists has assembled a timeline of 'protein history' that could explain why life began to produce oxygen on Earth.

Aug 6, 2014 · A-C are images captured by the W. M. Keck Observatory’s 10-meter Keck II telescope. They show Io at different infrared wavelengths on Aug. 15, 2013 (A-C).

Dec 21, 2017 · Astronomers have taken a fresh look at the nearby Alpha Centauri star system and found new ways to narrow the search for habitable planets there.

Oct 13, 2019 · Its size and surface gravity are much larger than Earth’s, and its radiation environment may be hostile, but a distant planet called K2-18b has captured the interest of scientists all over the world. For the first time, researchers have detected water vapor signatures in the atmosphere of a planet beyond our solar system that resides in the "habitable zone."

Nov 26, 2008 · The activity of bacteria has often been viewed as detrimental to fossils. Now, researchers have found that bacterial biofilms may help preserve fossils of embryos and soft tissues. Such fossils are incredibly valuable in studying the evolution of life.
