It’s a movement: Amateur scientists are making huge discoveries

Citizen scientists are advancing scientific knowledge.

When amateur radio operator Scott Tilley picked up a signal from NASA’s long-lost IMAGE weather satellite, he became the latest hero of the citizen science movement. He’s just one more science fan who devotes time and effort to his area of interest motivated strictly by enthusiasm. Though there’s no way to know how many such citizen astronomers and other scientists there are around the world, there’s no doubt that there are lots of them, not least because every now and then, one of them, like Tilley, makes an exciting discovery. Maybe you’re one of them. Or want to be.

Tilley’s in the habit of scanning the night skies of British Columbia every evening for several hours. The night he found IMAGE, he was trying to locate a particular USAF spy satellite. When he excitedly told his wife what he’d found, she just told him to tell NASA. Tilley tells the Washington Post, “By far, it’s the most important thing I’ve discovered. It’s a pretty cool thing in my world.” 

Though amateur astronomers have been watching the heavens for centuries, their pace of discovery has certainly picked up recently:

  • In 2012, a group of amateur astronomers discovered 42 planets.
  • In 2013, Michael Sidonio sighted a new dwarf galaxy, NGC 253-dw2.
  • In 2015, a group of amateur astronomers poring over NASA images spotted yellow “space balls” that NASA says are a rare view of the early stages of massive star formation.
  • In 2016, two amateur astronomers,  John McKeon from Ireland and Gerrit Kernbauer of Mödling, Austria filmed an asteroid impact on Jupiter in 2016.

    All of these examples have to do with astronomy, and it’s certainly true that this area of science was one of the first to involve non-professionals back in 1999, with Berkeley’s SETI@home desktop app. “SETI” is short for “Search for Extraterrestrial Intelligence,” and simply by running the screensaver-like app, any computer user could help crunch the massive amounts of alien-hunting data from Mexico’s Arecibo telescope during idle time. The project is still ongoing.

    Other data-crunching projects soon followed, such as Stanford’s folding@home that uses participants’ CPUs to emulate the way proteins fold themselves in the human body.

    Since those early days, scientists at universities, governmental agencies, and private companies have come to appreciate and rely on the ability of citizen scientists to act as large groups of observers — like the citizen astronomers above — contributors of massive data sets, and providers of computing time.

    It’s safe to say that whatever field of science interests you, at this point there’s likely a project you can help with. There are lots of places where you can find projects in which to get involved:

  • SciStarter currently lists 945 projects.

  • Zooniverse has 69 projects. The amateurs above who found the yellow space balls were participating in the Zooniverse “Milky Way” project for NASA.
  • Scientific American has 12+ pages of projects to choose from.
  • If you’re into space, check out Galaxy Zoo and NASA’s own Citizen Scientists page.
  • National Geographic’s Citizen Science Projects is for nature lovers.
  • Mashable has a page specifically for wildlife citizen science projects.
  • If all that’s not enough, Wikipedia keeps a list of projects.
  • Finally, just go to your favorite search engine and type “citizen science,” followed by your area of interest. Odds are you’ll get some promising hits.
  •  This is such an exciting time to be an amateur scientist. Not only are new discoveries appearing all the time, but between the internet and our powerful computers and electronic devices, we’ve got access to research tools professionals of just a few decades ago could only dream of. There are so many ways to make real a contribution. Without even quitting your day job.

    Behold, the closest-ever photo of a coronal streamer

    It was captured by the Parker Solar Probe, which is currently studying the star.

    Surprising Science
    • NASA's Parker Solar Probe is currently traveling closer to the sun than any other spacecraft before it.
    • The probe is recording data on the star to help scientists learn more about the star and its volatile nature.
    • Also this week, NASA released the first images of its Mars InSight lander taken from space.

    Iceland is officially worshiping Norse Gods again

    For the first time since the Vikings sailed, the Icelandic public will soon be able to worship classical Norse gods like Odin, Thor, and Frigg at a public temple built in their honor.


    For the first time since the Vikings sailed, the Icelandic public are worshiping classical Norse gods like Odin, Thor, and Frigg at a public temple built in their honor. "The worship of Odin, Thor, Freya and the other gods of the old Norse pantheon became an officially recognized religion exactly 973 years after Iceland’s official conversion to Christianity."

    Why victims of childhood adversity have a harder time achieving their goals

    Childhood trauma can affect a child's brain in dramatic ways for the rest of their lives.

    Mind & Brain
    • New findings suggest that childhood adversity may be directly linked to depression.
    • Adverse childhood experiences include a wide range of stressful or traumatic events brought upon by abuse and neglect.
    • Important landmark studies from the '90s suggest that these experiences are common and lead to a number of health, social and behavioral problems throughout life.
