    Where does the solar wind come from? The eclipse may offer answers

    The sun can’t keep its hands to itself. A constant flow of charged particles streams away from the sun at hundreds of kilometers per second, battering vulnerable planets in its path.

    This barrage is called the solar wind, and it has had a direct role in shaping life in the solar system. It’s thought to have stripped away much of Mars’ atmosphere (SN: 4/29/17, p. 20). Earth is protected...

    Potential ingredient for alien life found on Titan

    A molecule that could help build otherworldly life is present on Saturn’s moon Titan, researchers have discovered.

    Vinyl cyanide, a compound predicted to form membranelike structures, is created in Titan’s upper atmosphere, scientists report July 28 in Science Advances. There’s enough vinyl cyanide (C2H3CN) in the moon’s liquid methane seas to make about 10 million cell-like balls per...

  • 50 years ago, an Earth-based telescope spotted Saturn’s fourth ring

    Saturn: Four Rings

    Walter A. Feibelman of the University of Pittsburgh … has found evidence indicating a fourth ring [of Saturn].… Every 14.78 years, the rings of Saturn can be seen edge-on from Earth, and the past winter marked one of these opportunities.… The thin ring “extends to more than twice the known ring diameter” (or a total of 340,000 miles), and is so faint it cannot be...

    Key Einstein principle survives quantum test

    Particles with mind-bending quantum properties still follow a standard gravitational rule, at least as far as scientists can tell.

    The equivalence principle — one of the central tenets of Einstein’s theory of gravity — survived a quantum test, scientists report online April 7 at arXiv.org.

    In Einstein’s gravity theory — the general theory of relativity — gravity and acceleration...

  • 50 years ago, continental drift began to gain acceptance

    Drifting theories shake up geology

    Continental drift, a theory often considered amusing but rarely important, seems about to become the focus of a revolution in geology. At the least, it has already split the geological community into those who find the evidence for it “formidable” and those who think it is not yet formidable enough to constitute a proof. — Science News, April 29, 1967...

    There’s still a lot we don’t know about the proton

    Nuclear physicist Evangeline Downie hadn’t planned to study one of the thorniest puzzles of the proton.

    But when opportunity knocked, Downie couldn’t say no. “It’s the proton,” she exclaims. The mysteries that still swirl around this jewel of the subatomic realm were too tantalizing to resist. The plentiful particles make up much of the visible matter in the universe. “We’re made of them...

    Life on Earth may have begun as dividing droplets

    NEW ORLEANS — In a primordial soup on ancient Earth, droplets of chemicals may have paved the way for the first cells. Shape-shifting droplets split, grow and split again in new computer simulations. The result indicates that simple chemical blobs can exhibit replication, one of the most basic properties of life, physicist Rabea Seyboldt of the Max Planck Institute for the Physics of Complex...

  • Origin of photosynthesis may go further back than estimates from 50 years ago

    Evidence of Precambrian life

    From deep in the gold mines of South Africa’s Orange Free State has come evidence that there was some form of biologic activity on Earth at least 2.15 billion years ago. Polymerized hydrocarbon “chemo-fossils” found in the gold ores … [probably] were originally part of a rich bacterial and algal life in the Witwatersrand basin. Since the rock layers from...

    Newly identified continent Zealandia faces a battle for recognition

    Lurking beneath New Zealand is a long-hidden continent called Zealandia, geologists say. But since nobody is in charge of officially designating a new continent, individual scientists will ultimately have to judge for themselves.

    A team of geologists pitches the scientific case for the new continent in the March/April issue of GSA Today, arguing that Zealandia is a continuous expanse of...

    When a nearby star goes supernova, scientists will be ready

    Almost every night that the constellation Orion is visible, physicist Mark Vagins steps outside to peer at a reddish star at the right shoulder of the mythical figure. “You can see the color of Betelgeuse with the naked eye. It’s very striking, this red, red star,” he says. “It may not be in my lifetime, but one of these days, that star is going to explode.”

    With a radius about 900 times...
