  • Low-mass stars always born with a sibling: Many, like our sun, split up
    on June 14, 2017 at 1:19 pm

    Though astronomers have long known that many if not most stars are binaries, the question has always been, Were they born that way, or did one star capture another? Astronomers teamed up to systematically study very young stars inside their nest eggs, called dense cores, in the Perseus molecular cloud and concluded that all sunlike stars are born as wide binaries. Most subsequently split up, while the rest become tight binaries. […]

  • Cloudy with a chance of radiation: NASA studies simulated radiation
    on June 13, 2017 at 10:51 pm

    NASA's Human Research Program (HRP) is simulating space radiation on Earth following upgrades to the NASA Space Radiation Laboratory (NSRL) at the US Department of Energy's Brookhaven National Laboratory. These upgrades help researchers on Earth learn more about the effects of ionizing space radiation to keep astronauts safe on a journey to Mars. […]

  • Hot rocks, not warm atmosphere, led to relatively recent water-carved valleys on Mars
    on June 13, 2017 at 3:16 pm

    Some scientists have interpreted water-carved valleys on Mars formed within the last few billion years as a sign of either an active groundwater system or of transient warm periods in the atmosphere. But new research shows that snow and ice melted by hot impact ejecta could have produced enough water to carve those valleys with no groundwater or heat wave required. […]

  • Composition of Earth-size planets in TRAPPIST-1 system
    on June 8, 2017 at 6:55 pm

    An astrophysics researcher has identified the possible compositions of the seven planets in the TRAPPIST-1 system. Using thousands of numerical simulations to identify the planets stable for millions of years, Quarles concluded that six of the seven planets are consistent with an Earth-like composition. The exception is TRAPPIST-1f, which has a mass of 25 percent water, suggesting that TRAPPIST-1e may be the best candidate for future habitability studies. […]
