  • Water on Earth predates the solar system, and even the sun

    Water on Earth predates the solar system, and even the sun
    Some of the water molecules in your drinking glass were created more than 4.5 billion years ago, according to new research. That makes them older than the Earth, older than the solar system — even older than the sun itself. In a study...
  • Fall starts Monday? Sez who?

    Monday is the first day of autumn. This is according to the chart of astronomical seasons and the little calendar here at my desk. Sept. 22, astronomers believe, is the first day of the fall season this year. Astronomers also believe, ridiculously, that...

    Suddenly, the sun is eerily quiet: Where did the sunspots go?
    Our sun has gone quiet. Almost too quiet. A few weeks ago it was teeming with sunspots, as you would expect since we are supposed to be in the middle of solar maximum -- the time in the sun's 11-year cycle when it is the most active. But now, there is...

    'Magic Island' may show Titan's oceans are hardly pacific

    Johns Hopkins University scientists are building a telescope meant to look at space in a way no one has before, hoping to probe the blackness between planets, stars and galaxies, into deep time and the mystery of how it all began. For decades,...
  • 'Cosmos' Writer Ann Druyan on Science and Seth MacFarlane

    Over a vegetarian breakfast at the London in West Hollywood in June, writer Ann Druyan contemplated the "Cosmos." She had been there before as a writer on the first "Cosmos" series in 1980 when her husband, the late astrophysicist and astronomer Carl...
