Measuring the Impacts of Light Pollution
Light pollution is pervasive, and its impact on people is larger than you might think.
LIGO Detects Second Black Hole Collision
The gravitational wave observatory has detected a second event, heralding a new era in astrophysics. The day after Christmas last year, the cosmos quietly gifted scientists with gravitational waves — ripples in the fabric of spacetime – produced in a collision between two stellar-mass black holes. It’s the second event…
The World at Night's Earth & Sky Photo Contest: The Winners
The winners of the 7th annual Earth & Sky Photo Contest highlight the fragile beauty of our heavens.
Missing Dwarf Galaxies Never Were
Astronomers may have solved the case of the Milky Way’s missing satellite galaxies. The solution? The galaxies never existed.
Solstice Brings Late Nights, Bright Sights
Celebrate the June 20th solstice, when the Sun and the full Strawberry Moon combine their powers to illuminate both day and night.
Clouds Rain Down on Black Hole
Astronomers have detected three cold gas clumps falling toward a galaxy's center — at odds with the prevailing idea for how black holes grow.
Comets Break Up and Make Up
Comet 67P/Churyumov-Gerasimenko appears to have split into two segments that briefly orbited each other and then slowly merged into a new configuration.
LISA Pathfinder Surpasses Expectations
First science results from ESA's LISA Pathfinder mission exceed expectations, with five times the sensitivity. This result paves the way for a future full-scale gravitational wave observatory in space.
Dual Supernovae Light Up June Nights
Supernovae are popping up everywhere! Two stars flamed out millions of years ago and at least one is an easy catch right now in amateur telescopes.
VLA Probes Deeply into Jupiter’s Atmosphere
Astronomers have new radio images of Jupiter that allow them to see deep into its atmosphere.
Tour June's Sky: Three Planets at Nightfall
Sky & Telescope's astronomy podcast takes you on a guided tour of the night sky. After the Sun sinks from view, enjoy watching Mars and Saturn near Scorpius in the southeast and Jupiter near Leo well up in the southwest.
Saturn's Splendid Summer Show
It's showtime for the King of the Rings! Time to get your telescope out to see and share Saturn, which comes to opposition this week.
The Gaseous Footprints of Baby Planets
Astronomers re-analyzed two-year-old data from the ALMA observatory in Chile and discovered gas gaps that probably indicate baby planets in the disk around a young star.
The Kavli Foundation Q&A: How Did Nature's Heaviest Elements Form?
The Kavli Foundation hosted a Q&A with three astronomers to probe the recent discovery of hard-to-produce heavy elements in a nearby dwarf galaxy. The discovery sheds light on stellar histories and galactic evolution.
Galaxy Cluster Spotted in Early Universe
Astronomers discover a vast collection of young galaxies from the early universe.
How Dead Galaxies Stay Dead
A galaxy in the midst of a merger isn’t forming stars, even though it could. Astronomers think the galaxy’s central black hole might be the reason why.
Disk Around HR 8799 Hints at Hidden Fifth Planet
A high-resolution ALMA image of the HR 8799 planetary disk suggests undiscovered planet.
