"As sure as the Sun rises in the east . . ." Except it doesn't! Find out how Earth's tilt changes the location of sunrise (and sunset) throughout the year.
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.
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.
What’s inside a black hole? Wormholes? Alternate universes? If you fell into a black hole, only one thing’s for sure: its tidal forces would kill you.
Learn what a black hole is, what we mean by “singularity” and “ergosphere,” and why we think black holes are real.
Osiris-REX recently began a 2-year journey to the asteroid Bennu. The Kavli Foundation spoke with three experts about what the spacecraft may discover.
All galaxies are fated to "die" and stop making stars. The reason may lie with the supermassive black hole lurking in their cores.
Courtesy of The Kavli Foundation, read the conversation between two 2016 Kavli Prize laureates as they discuss the struggle to detect gravitational waves and how their discovery is changing our understanding of the universe.
The phases of the Moon are determined by the relative positions of the Moon, Earth, and Sun.
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.
Learn how powerful new telescopes and techniques are enabling scientists to probe planets in the earliest stages of development.
To mark the start of a new era of astronomy, three principal LIGO researchers speak with The Kavli Foundation on their epic discovery and how it will transform the way we see the cosmos.
Crowd-sourcing the universe: Thanks to online portals, legions of volunteer astronomers are turning their eyes to the sky and doing extraordinary science. Three scientists discuss the future of citizen astronomy.
A newfound alien world orbiting a small, nearby star could be one of the first exoplanets scientists get to investigate in detail. Three astrophysicists discuss the possibilities.
Watch a Q&A with two astronomers on the promise of Hubble's successor telescope, courtesy of The Kavli Foundation. Scientists have unveiled a bold proposal for a giant new space-based telescope that would be far more powerful than today's observatories. Called the High Definition Space Telescope (HDST), the instrument is essentially a supersized Hubble Space Telescope,…
Three experts joined The Kavli Foundation for a live Q&A to discuss New Horizons' long journey to the distant and fascinating world of Pluto.
We finally know the ingredients that fire up a particular kind of supernova. Four researchers explain why a better understanding of how certain stars die can help reveal the evolution of the cosmos and its galaxies.
A new exoplanet closely matches what astronomers think Jupiter looked like in its infancy. Astrophysicist Bruce Macintosh of the Kavli Institute for Particle Astrophysics and Cosmology at Stanford discusses why this discovery might help us understand how planets arise.
Satellite dwarf galaxies orbiting the Milky Way should help scientists better grasp the universe's evolution while also homing in on dark matter's identity.
Courtesy of The Kavli Foundation, Sky & Telescope is featuring an in-depth Q&A with two astrophysicists and a theoretical physicist on what the Large Synoptic Survey Telescope will teach us about dark matter and dark energy.
Recently, two high-profile experiments released new data and analyses of the universe’s earliest light. Here, three preeminent scientists discuss the latest results, what they mean for the theory of cosmic inflation, and what we can expect to learn about the very early universe in the coming decade.
Scientist George Efstathiou weighs in on the latest results from the Planck satellite and what they say about cosmic inflation, the first stars, and more.
