1. The week’s best photojournalism

    In some of the week’s most memorable images, the sun sets over a herd of Hungarian cattle, a Palestinian boy practices his parkour skills, and more


  2. This ‘diamond in space’ is the coldest star ever detected

    Astronomers have identified the coldest dwarf star ever detected


  3. As a film critic, I’ve seen nearly 4,000 movies over the last 15 years. Right now, I can’t think of one worse than Movie 43.

  5. When a star dies, it explodes into a supernova.  Then it glows like a puffy, celestial jellyfish.

    Here’s why.

  8. Discovered: A far-off galaxy from the dawn of time 

    Astronomers caught a glimpse of what they think is the most distant galaxy ever seen. While it doesn’t “look like much,” the “fuzzy red orb” is an astonishing 13.2 billion light years away, says Rebecca J. Rosen at The Atlantic. That’s not much older than the universe itself, and this tiny galaxy may have emerged less than 200 million years after the Big Bang. It’s like an archeologist finding an incredibly old artifact that’s still relatively intact.



  9. An artist’s rendition of a ‘vampire star’ sucking gas from another star so that it can become bigger and brighter. 

    Scientists have long known that some of the biggest, brightest stars in our galaxy are part of binary two-star systems. But a new study suggests that far more of these stellar duos exist than once believed, with many exhibiting signs of a violent relationship. Indeed, in many pairs, one star will often suck the life from its partner to become bigger, more powerful, and more luminous.

  10. A star being gobbled by a massive black hole sends out a “mayday call,” and Earth receives it. This happens “only once every 100 million years.”

  11. Dwellers of the fictional “Star Wars” planet Tatooine live under two suns. Earthlings may soon enjoy the same distinction. Betelgeuse, the ninth-brightest star visible to humans, is expected to transform itself from a “super red giant” to a “supernova.” If it does so as soon as the end of 2012, “we could see a second sun light up the sky, if only for a matter of weeks.” Others say the process could take another million years and that the 2012 prediction is just apocalyptic wishful thinking. Here, the details.


  12. Turns out all these years, I’ve been living a lie. But boy did I buy into the whole Sagittarius deal.… All those years I thought I was free spirited? Turns out I was just super irresponsible.
    — John Cave Osborne at Babble reacts to the news that his sun sign, like everyone else’s, might not be what he thought it was.

  13. We are not alone. At least, we may not dwell on the only life-giving planet in the universe. In September, scientists identified a “Super Earth" 2,283 light years away, the first of several Earth-like planets discovered this year. Just a few weeks later, a so-called "Goldilocks planet" — neither too hot nor too cold for liquid water — was spotted a mere 20 light years away.

    The Super Earth made it onto our list of 2010’s Top Mysteries of Space, as did an asteroid big enough to destroy Washington, D.C., our shrinking moon, and a “solar tsunami.”

    Here’s the year in astronomical discoveries
