  • Vesta – An asteroid full of surprises

    I don’t have time to write about this… but I’m not sure that matters, because my words can’t do justice to the beauty of this video of Vesta from the Dawn team. Their words will do a much better job of describing things, including
  • Why Astrobiology?

    Earlier this month, I was invited to deliver lectures at INFN (Italian Nuclear Agency) in a summer school entitled “Terrestrial atmosphere and cosmic rays” held at the LNGS campus (Gran Sasso Naional Lab) in L’Aquila, Italy.

  • Closing in on Extrasolar “Earths”

    A nice summary of recent exoplanet discoveries. It’s early days yet, but a preliminary estimate is that the percentage of stars that have Earth-like planets (i.e., rocky and in the habitable zones of their stars) is about 34%. As this article points

Dr. Atri is currently a India Department of Atomic Energy (DAE) Visiting Fellow at the Department of High Energy Physics in the Tata Institute of Fundamental Research in Mumbai, India. He studies the interaction of high-energy particles of astrophysical origin with the terrestrial atmosphere and
  • Have we found a potential “forest moon?”

    Based on some conversations I’ve had with others (that are also NOT in the know), I’ll offer up another possibility for what the Kepler team might announce at their press conference later today… the first discovery of an exo-moon. It could even be an Earth-sized moon orbiting a gas giant. Sound familiar? That would certainly
