Astronomers have discovered that one galaxy of a nearby double-galaxy system has a giant, star-studded ring.
Astronomers have identified the smallest supermassive black hole ever detected in a galaxy’s center.
Astronomers have found that a massive filament of gas in the early universe actually seems to be a humongous, galaxy-forming disk.
Astronomers have confirmed the existence of an exoplanet found via microlensing — the first time they’ve been able to successfully follow up on this method.
Astronomers have detected what looks like auroral emission on an ultra-cool star.
Submit names for Hayabusa 2's target asteroid, 1999 JU3. Deadline is August 31st!
NASA’s New Horizons spacecraft whizzed by Pluto this morning just before 8 a.m. EDT at nearly 14 km/s (31,000 mph), about 12,500 km (7,750 miles) above the surface.
The spacecraft orbiting Comet 67P/Churyumov-Gerasimenko has found 18 holes in the nucleus's surface.
New ALMA observations reveal low levels of dust in nine early galaxies, suggesting astronomers should revise some of their calculations.
Scientists have detected glass in Martian craters, created by the fierce heat of impacts that melted the Red Planet’s surface.
Visit the dwarf planet Ceres in this video animation created from images taken by NASA’s Dawn spacecraft.
Two new studies confirm that the white dwarfs that explode as Type Ia supernovae can approach death in two different ways.
Astronomers have discovered 195 compact elliptical galaxies, upping the known number of these weird galaxies sixfold.
Astronomers have found massive galaxies 3 billion years after the Big Bang that are dying from the inside out.
Thanks to NASA’s Dawn spacecraft, we’re finally seeing more of the asteroid Ceres than a fuzzy ball.
On April 1st astronomers and other important folk got serious about science jokes in an annual tradition of scientific tomfoolery.
NASA’s MAVEN spacecraft has detected dust high in Mars’s atmosphere and auroras across the planet’s northern hemisphere.
Astronomers have detected what look like four undulations in the Milky Way Galaxy’s disk. If the structures are all part of the disk, our galaxy is more than half again as large as we thought it was.
With the goal of better understanding Earth’s space weather environment, NASA’s Magnetospheric Multiscale (MMS) mission launched just over an hour before midnight on March 12th from Cape Canaveral.
A small galaxy 700 million years after the universe’s birth has a dust reservoir that makes it look like a much older galaxy.
Astronomers have discovered one of the brightest quasars in the early universe. The source, SDSS J010013.02+280225.8 (hereafter J0100+2802), is powered by a supermassive black hole at a redshift of 6.3, meaning that its light left it 12.8 billion years ago.
Scientists studying ice here on Earth think they’ve confirmed why comets have hard crusts covered in hydrocarbon gunk.
This image series, taken by NASA’s New Horizons spacecraft in late January 2015, reveals the dwarf planet Pluto and its largest moon, Charon, orbiting their common center of mass.
The Planck team has finally released its full-mission data, revealing a remarkably detailed view of our universe and our galaxy.
The long-awaited analysis of spiraling polarization patterns called B-modes affirms that these signals, purportedly from the universe’s post-birth inflation, are probably from dust in our galaxy instead.
