Between the discovery of the new comet ASASSN1 and two stellar explosions, there's a lot happening in the sky this week. Take your telescope out and see what all the excitement's about.
A new study proposes a possible source for the mysterious Mars Trojan asteroids: the Red Planet itself.
Think the total solar eclipse is "sold out"? Think again — and grab your camping gear. Private campsites and RV parks within the long path of totality are still available for those willing to travel.
The Sun, now halfway through its life, might be slowing its magnetic activity, which could lead to permanent changes in the sunspots and auroras we see.
An object previously identified as a free-floating, large Jupiter analog turns out to be two objects — each with the mass of a few Jupiters. This system is the lowest-mass binary we’ve ever discovered.
The European Space Agency switched off its groundbreaking LISA Pathfinder mission this week.
Russia's first crowd-funded satellite, named Mayak (Russian for "beacon of light"), promises to be the “brightest object in the night sky next to the Moon.”
A new study of a nearby cluster of newly formed stars reveals that brown dwarfs may rival stars in the Milky Way in number, with one brown dwarf for every two bona fide stars.
Astronomers found six runaway stars when they applied a neural network to data from the European Space Agency’s Gaia mission, which is set to map a billion stars across the Milky Way and beyond.
A team of amateurs observers, some armed with just 3-inch telescopes, have found that the main-belt asteroid 113 Amalthea probably has a small companion.
NASA's Juno Spacecraft delivers stunning closeup views of Jupiter's famous swirling Great Red Spot storm.
The celestial event of this young century — the great American total solar eclipse of 2017 — is now just weeks away. The biggest remaining question is, where will you be when the Moon’s shadow arrives?
Thanks to the effects of gravitational lensing, a team of astronomers was able to reconstruct a distant galaxy and study its unexpectedly clumpy star forming regions.
At opposition this week and as bright as it will be for the next 190 years, it's time to find your way to Pluto, a frigid enigma at the edge of night.
The region around Sgr A*, the 4-million-solar-mass black hole at the heart of our galaxy, is a complex and dynamic place. New Atacama Large Millimeter/submillimeter Array (ALMA) observations of the Milky Way’s center now reveal more about this harsh, inhospitable environment.
What is the National Space Council and what will it do? A look back through history provides some possible answers.
Eclipse-related outreach activities will abound this August, but how do we best capitalize on this rare celestial event after it happens? Astronomers Without Borders has developed a Sun-focused curriculum and is looking for volunteers to help teachers implement it.
Astronomers monitoring a tight pair of supermassive black holes have observed their orbital motion.
Researchers are figuring out how to use a nature-inspired "gecko gripper" technology to solve the mounting problem of space debris.
Jupiter and Saturn are easy to spot in the evening sky, as you'll discover in July's fun and informative astronomy podcast.
A recent NASA study outlines possible dedicated missions to the "ice giant" planets Uranus and Neptune that might leave Earth as early as 2030.
Dennis di Cicco interviews several vendors about their newest products — watch and find out full details on new lines of astronomy equipment.
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?
