    Hopkins scientists pursue origins of the universe
    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,...
  • Solar flares expected to 'shockwave' Earth today

    Solar flares expected to 'shockwave' Earth today
    Feelin’ the heat? Three massive solar flares could “shockwave” Earth today. That’s the upshot from NASA and NOAA, after powerful plasma ejections erupted from the sun earlier this week. The flares pose no danger to humans,...

    Hubble peers deep into the universe, reveals teenage galaxies
    Astronomers using the Hubble Space Telescope have released one of the most comprehensive images of the universe ever taken, and it is awesome. The image you see below is not wide, but it is so deep that it stretches back to just a few hundred million...
  • Two ancient worlds found just 13 light-years from Earth

    Two ancient worlds found just 13 light-years from Earth
    Scientists have discovered two ancient planets orbiting a strange old star right in our stellar backyard. One of the newly found planets is perhaps five times the mass of Earth, and astronomers believe it is the right distance from the host star to...

    "Cosmos" wrapped its 13-episode run this week by emphasizing the importance of knowledge and critical thinking by way of the scientific method in "Unafraid of the Dark." Despite a few missteps here and there, host Neil de Grasse has taken us on a...
  • Two X-class solar flares in less than 2 hours, and more may come soon

    Two X-class solar flares in less than 2 hours, and more may come soon
    The sun unleashed two X-class solar flares in the span of one hour and 10 minutes Tuesday morning, and there is a good chance that more may be coming soon. Solar flares are big bursts of radiation that come from dark areas of the sun called sunspots. An...

  • Meteor shower a bust; 'models were clearly wrong'

    Meteor shower a bust; 'models were clearly wrong'
    A predicted "storm" of meteors overnight turned out to be mostly a bust, though some in the Midwest U.S. got a better glimpse of the shower than in the mid-Atlantic. The Earth was expected to pass through a debris trail left behind a comet that was...
