Some academic and citizen-science groups came up with neat initiatives for eclipse day. Let’s find out how they did.
Join a citizen-science campaign on August 21st to record 90 minutes of the Sun's changing corona. You'll need your smartphone and the Megamovie Mobile app.
Citizen scientists have discovered a brown dwarf 100 light-years from the Sun, and more finds are sure to come from the Backyard Worlds citizen-science project.
The possible discovery of a massive ringed planet in Orion needs confirmation — and amateur astronomers can help.
Ten years ago, La Palma was declared a "Starlight Reserve" and measures were implemented to protect its skies from light pollution. How did they work?
Hankering to discover new solar systems or understand our own? These citizen science projects and public data troves will help you fill your free time.
Stellar streams are the remains of dwarf galaxies that once orbited the Milky Way. We showcase here stunning images of these galactic ghosts.
Calling all imagers! Three comets will make close flybys of Earth over the next two years. Join a new pro-am effort to make the most of this rare triple play.
Light pollution is pervasive, and its impact on people is larger than you might think.
Planetary scientists are counting on amateur observations to enhance the results from NASA's forthcoming Juno mission.
The Kepler team unexpectedly found the planet-hunting spacecraft in emergency mode on April 7th, but with the spacecraft recovered, hopes are high that its newest search, this time for rogue planets, is still on. Read on to see how amateur observations can help!
With astronomy being celebrated around the globe this month, join the fun by participating in a unique lunar observing challenge: track down 20 features once thought to show evidence of change from weather, geology, and even life.
What began as a student's simple idea a decade ago has grown into a worldwide celebration of the night sky and easy ways to reduce light pollution.
It's high time that we amateur astronomers got serious about protecting the night sky from light pollution.
Solar scientists hope an armada of amateur astrophotographers can record the inner corona’s evolution throughout the 2017 total solar eclipse.
Crowd-sourcing the universe: Thanks to online portals, legions of volunteer astronomers are turning their eyes to the sky and doing extraordinary science. Three scientists discuss the future of citizen astronomy.
Take part in a collaborative project that will unite amateur and Hubble Space Telescope observations to better characterize nearby exoplanets.
Participate in a world-wide campaign to observe and photograph Comet 67P/C-G as it approaches and recedes from the Sun with Rosetta in tow. Your observations matter.
Thanks to the help of the general public, astronomers have discovered a new signature marking a hidden phase of star formation.
Citizen scientists are exploring exoplanets’ birthplaces, classifying more than 1 million infrared sources and finding 37 disk candidates (so far) for follow-up study.
International Observe the Moon Night is an event that encourages people to "look up" and enjoy our nearest neighbor. This year's InOMN is Saturday, September 6th. Here's a quiz: What astronomical object looks amazing no matter what the magnification, never looks exactly the same no matter how often you view it, and can be observed…
Amateur astronomers have teamed up with the pros to produce four stunning multiwavelength images of galaxies M101, M81, M51, and Centaurus A.
Join astronomers in two new citizen science projects, Space Warps and Planet Four, that will have you investigating the warped light from faraway galaxies and the ever-changing Martian landscape.
"Globe at Night" is a fun, easy, and worthwhile activity for you and your family. Please join this worldwide campaign to measure the darkness of night skies everywhere from April 29th to May 8th.
Amateur astronomers perform a crucial role in detecting exoplanets by a technique called microlensing, including the most recent discovery of a multiple-planet system.
