year’s biggest storıes

This issue features our annual “Top 10 space stories of the year” roundup, this time written by Contributing Editor Liz Kruesi. And it has been an exciting year full of surprises. Of course, we came out of the gate early with a discovery that was 40 years in the making. On February 11, 2016, scientists announced the detection of gravitational waves, ripples in space-time caused by the collision of two black holes. This incredible discovery was the first such detection of an event postulated by Einstein a century earlier. And the idea for the detector that could snag such an observation was long in the making, too. In the 1970s, Rainer Weiss, Kip Thorne, and others pushed the National Science Foundation to build a large interferometric observatory, one that could detect tiny…

HOT BYTES >> TRENDING TO THE TOP DARK MATTER LUX-ZEPLIN, an upcoming dark matter detector 100 times more sensitive than current instruments, is on track to begin operations by 2020 SHORT VISIT On September 11, Russian astronomer Gennady Borisov identified Comet C/2016 R3 swooping close to the Sun. The comet now shares his name. HIDEAWAY Spiral galaxy M77 hosts a supermassive black hole that kicks up so much material, it hides itself from optical telescopes. SNAPSHOT Earth-mass vs. Earth-like The Proxima Centauri planet discovery is tremendously exciting, but folks, it ain’t another Earth. This has been quite a year for astronomical discovery, with gravitational waves, Juno’s arrival at Jupiter, and now the discovery of an exoplanet orbiting Proxima Centauri, the closest star to the Sun. At 4.2 light-years away, Proxima, which is an outlying member of the Alpha Centauri multiple star…

talking totality

STRANGEUNIVERSE This year may bring your life’s most astonishing experience. In August, for the first time in nearly four decades, a total solar eclipse will sweep across the mainland United States. Most backyard astronomers have never seen one. No surprise — they’re a rare event, and expensive thanks to equipment and travel concerns. For any spot on Earth, totality happens once every 360 years on average. Some places, like Los Angeles, will wait more than a millennium. Everyone’s seen photos. The image of a black Moon surrounded by the solar corona is familiar. But is it merely a lovely spectacle like a lunar eclipse or a nice comet? Only when viewed in person does the observer realize that this is the most wondrous event in his or her entire life. One reason is…

From the past to a bright future I am a sophomore in high school who has loved astronomy since I first learned about it when I was 7. A few years back, when I was just strolling down the magazine aisle, I spotted Astronomy and bought it. Ever since then, I cannot stop reading it! Your magazines are very well written, jam-packed with tons of intriguing information, contain many beautiful photos and illustrations, and always contain the latest discoveries It is so great to have a resource that always provides up-todate knowledge. I’m always learning so many things. You cannot find these things written in the outdated books we have at school. Often I find myself sharing your articles with my fellow classmates and teachers, and getting reactions of surprise and interest.…

STARSPOT TRICKS. Astronomers caution that starspot activity — a starspot is the stellar equivalent of a sunspot — can mask how exoplanets seem to be aligned with their star’s rotation, leading to inaccurate orbital calculations. BROWN DWARFS FORMING PLANETS Astronomers have found four brown dwarfs surrounded by disks strikingly similar to the doughnutshaped clouds of dust around stars that are actively birthing new planets. Whether in our solar system or in others, planets form out of a disk of dust and gas around a young star. While planetary scientists still debate the details, the general idea is that the dust forms pebbles, then boulders, then planets, while the gas is swept up by planets or eventually cleared out by solar wind. But such disks also can form around brown dwarfs, the smaller, non-hydrogenfusing…

top 10 space stories of 2016

Gravitational wave astronomy began in 2016, when scientists revealed that humans could now look upon the universe with never-before-used senses. Advanced instruments had detected the quiet rumble of black holes merging a billion light-years away, producing gravitational waves that passed through Earth. While that incredible discovery tops the year of space science, our own solar system held its share of news. The Juno spacecraft arrived at Jupiter all set to unlock a treasure-trove of secrets. In study after study, scientists found hints of surprising worlds orbiting beyond Pluto. And rocket technology took a huge leap forward when two private companies showed that reusability works. Of course, the unexpected also made for big news, from weird radio signals that revealed yet another surprise, to the most powerful magnets in the universe showing how…
