    Using general relativity to magnify the cosmos

    One of the most powerful known magnifying lenses isn’t found on Earth. The lens is built from stars, gas and dark matter and lies about 4 billion light-years away. As astronomers peer through it, they are finding the seeds of galaxies that were scattered around the universe more than 13 billion years ago.

    The lens is known as Abell 2744, a cosmic pileup where four groups of galaxies are...

    Discovery of neutrino mass earns 2015 physics Nobel

    The discovery that subatomic particles called neutrinos have mass has won Takaaki Kajita of the University of Tokyo and Arthur McDonald of Queen’s University in Kingston, Canada, the 2015 Nobel Prize in physics. The scientists led two sophisticated experiments that found that the elusive particles can morph from one variety into another — a phenomenon that can occur only if neutrinos have mass...

    Einstein's genius changed science's perception of gravity

    Albert Einstein opened humankind’s eyes to the universe.

    Before Einstein, space seemed featureless and changeless, as Isaac Newton had defined it two centuries earlier. And time, Newton declared, flowed at its own pace, oblivious to the clocks that measured it. But Einstein looked at space and time and saw a single dynamic stage — spacetime — on which matter and energy strutted,...

    Coffee reveals itself as an unlikely elixir

    For a historically mistrusted drink, coffee is proving to be a healthy addiction. Scientific findings in support of coffee’s nutritional attributes have been arriving at a steady drip since the 1980s, when Norwegian researchers reported that coffee seemed to fend off liver disease. Since then, the dark brown beverage...

    Mars’ ionosphere mystery explained

    Probing a planet’s ionosphere can be all about the timing. Confusion about how many layers of charged particles exist in the Martian atmosphere might be due to what time of day measurements were made.

    Several spacecraft have, over the years, detected two ionosphere layers on the Red Planet. But both Viking landers noticed...

    The first spacecraft buzzed a comet today in 1985

    Thirty years ago today, the International Sun-Earth Explorer 3 probe became the first spacecraft to fly by a comet. Launched in 1978, ISEE 3 spent several years loitering near Earth, investigating the solar wind and Earth’s magnetic field. Renamed the International Cometary Explorer, or ICE, the probe took...

    Apes do the darndest things

    View the video

    Wildfires dart through tall grass and tree stands at Fongoli, Senegal, during a roughly seven-month dry season. Chimpanzees living in this West African savanna coolly monitor the approaching fires from perches in trees or from ravines. As flames near, the apes retreat just enough to stay safe, sometimes climbing a tree or scurrying into nearby woods....
