'Theory of Everything' Brilliantly Dramatizes Paradox of Modern Science
I met Stephen Hawking in the summer of 1990, when I spent five days in northern Sweden at a conference attended by 30 or so leading cosmologists.
Failure to Launch Is Always An Option
Do not try this at home. A Russian Proton-M launch goes wrong – and it can happen to anyone (wait for the shock wave). A rocket is a controlled bomb.
Evidence Builds for Dark Matter Explosions at the Milky Way’s Core
Unexplained gamma rays streaming from the galactic center may have been produced by dark matter, but more mundane explanations are also possible
Complex Life Owes Its Existence To Parasites?
Is complex life rare in the cosmos? The idea that it could be rests on the observation that the existence of life like us – with large, energy hungry, complicated cells – may be contingent on a number of very specific and unlikely factors in the history of the Earth.
The Black Hole in Interstellar Looks Amazingly Realistic
Wired has a fun piece about physicist and black-hole guru Kip Thorne's work on the film Interstellar, which comes out November 7. We've known the premise of the film for a long time: Earth is a disaster, the human race is on the verge of extinction, and mankind must find a new home.
Ancient Halo Stars Cast the Milky Way’s First Light
Hubble spots a star in our galaxy’s halo that likely predates its oldest star clusters
Recent Lunar Discoveries Reveal a "New Moon"
Think you know about the Moon? I did, but then I started reading ‘The New Moon: Water, Exploration, and Future Habitation‘ (Cambridge University Press, 2014) and realized that my knowledge amounted to a teensy scrap of lunar dust.
Surfer-Physicist Offers Alternative to String Theory, Academia
In 2007 Garrett Lisi was a 39-year-old physicist, unaffiliated with any institution, toiling in obscurity on what he called "An Exceptionally Simple Theory of Everything,” which could account for all of nature’s forces.

X-ray data hinting at axion particles draw interest and cautionary warnings
Track Cosmic Rays with Smartphone App
Take part in a citizen-science project by helping researchers track high-energy cosmic rays via a network of smartphone users. Clara Moskowitz reports
