Prepare for the 2020 solar eclipse with these basic facts and other resources.
Researchers discuss new signs of chemistry favorable to life at Mars, Europa, and Enceladus — plus how to probe for its presence with interplanetary missions.
From serendipitous camping trips to forging international consensus on big-budget observatories, the 2018 Kavli Prize laureate discusses her personal and professional journey into the field of astrochemistry.
The just-launched Transiting Exoplanet Survey Satellite (TESS) could soon provide the breakthrough identification of dozens of potentially habitable exoplanets right in our cosmic backyard
A newfound star in a nearby galaxy appears to have cheated death by blowing up at least twice as a supernova. It could be a throwback to the first stars that ever formed.
A slow, relentless rhythm, known as the saros cycle, is hidden away in the movements of the Moon and Sun. How does it foretell eclipses — and how could Babylonians discover its existence long before modern science and technology?
The moment the Sun reaches its southernmost point in the sky marks the December solstice, the official beginning of winter in the Northern Hemisphere (where it is called the winter solstice) and a time of great celebration in many northern cultures.
The prevailing view of the universe has just passed a rigorous new test, but the mysteries of dark matter and dark energy remain frustratingly unsolved.
From oxygen-thin mountaintops to barren deserts to the South Pole, many of the world’s most powerful telescopes are in distant, inhospitable environments. Three researchers share their adventures pursuing science at the farthest corners of the world.
A few weeks ago we took to Twitter and Facebook to find out what questions you wanted answered about the August 21st Total Solar Eclipse. Now we're back with Part II of the answers!
Much to their surprise, scientists are finding dozens of black holes deep within densely packed collections of stars called globular clusters. Astrophysicists are using a record-breaking computer simulation to learn their secrets, including whether the clusters gave rise to recently observed ripples in space-time.
Thanks to a record haul of new, ultra-distant quasars—powerhouses of light from the farthest reaches of the universe—astrophysicists can now piece together the rise of mighty objects in the early cosmos.
