Several thousands of amateur astronomers flocked to the 2017 Northeast Astronomy Forum, held every year in Suffern, New York, to see some of the hottest new telescopes, mounts, cameras, eyepieces, and other astronomy equipment at one of the world's largest astro trade shows. Former S&T editor Dennis di Cicco interviewed several vendors about their newest…
Following the release of the 2018 budget, the space agency has ordered an “orderly closeout” for the Asteroid Redirect program.
Direct imaging of exoplanets was once only possible for the brightest of planets orbiting the dimmest of stars — but improving technology is turning this into an increasingly powerful technique. In a new study, direct-imaging observations of the Jupiter-like exoplanet 51 Eridani b provide tantalizing clues about its atmosphere.
Are astronomers being misled about a possible ninth planet by the quirky alignment of orbits that they’re finding in the distant Kuiper Belt?
With two months to go until the total solar eclipse on August 21, it's time to get planning — if you haven't already!
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.
A sparse galactic neighborhood could clear up certain problems with our understanding of the universe.
The most comprehensive and detailed exoplanet catalog released yet marks the end of an era for Kepler, the planet-hunting telescope.
China's Hard X-ray Modulation Telescope (HXMT) headed to orbit this past weekend.
At what point does a clump of gas ignite, turning into a star? Astronomers now have an answer to what makes a star — and what makes a brown dwarf.
Saturn, considered by many the most beautiful sight in the sky, comes to opposition this week with its rings in full tilt. You won't want to miss it.
A team of astronomers has taken a close look at a nearby galaxy — and discovered an unusual structure that sheds light on supermassive black holes’ relationships with their host galaxies.
Xenon measured by the European Space Agency's Rosetta spacecraft has shed light on a long-standing mystery about the role comets played in Earth's formation.
A new study of data archived from the Galaxy Evolution Explorer (GALEX) spacecraft is revealing just how hard life might be on planets like those in the TRAPPIST-1 system.
New ideas have emerged to explain Tabby's Star, officially known as KIC 8462852, but the jury's still out on the cause of the star's weird behavior.
On June 3rd, two dozen teams of observers in South America and South Africa tried to learn something about distant 2014 MU69, which New Horizons will visit in early 2019.
Astronomers announce the discovery of bloated gas giant KELT-9b, the hottest "hot Jupiter" exoplanet known orbiting a short-lived massive star.
The possible discovery of a massive ringed planet in Orion needs confirmation — and amateur astronomers can help.
NASA's Parker Solar Probe, set to launch in 2018, will be humanity's first effort to "touch the Sun," revolutionizing our understanding of the Sun's corona, the solar wind, and the greater heliosphere.
Ground- and space-based observations have now shed intriguing new light on a mysterious radio source more than 3 billion light-years away.
Just a mile across, a pair of moonlets found orbiting Jupiter bring the planet's total satellite count to 69.
A Moon-orbiting camera briefly shuddered — then got back to work — when it was hit by a tiny bit of space rock no bigger than a pinhead.
Scientists with the gravitational-wave observatory announce another discovery, this time of a black hole merger twice as far away as previous detections.
June's astronomy podcast takes you on a star- and planet-studded tour of the sky you'll see after sunset.
Astronomers may have watched a star collapse directly into a black hole — minus the supernova. The failed supernova could help understand how stars die.
