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.
Sky & Telescope features a Q&A between The Kavli Foundation and three astrophysicists who discovered two enormous and unexpected structures radiating from the center of our galaxy. They discuss what these mysterious bubbles can tell us about the history of the Milky Way and how they could help in the search for dark matter.

Three astrophysicists discuss preparations for three recently funded dark matter experiments, and the likelihood that one of them will strike gold.
Locally, spacetime is curved by the presence of massive objects. The total mass and energy density of the universe also has an effect on the overall curvature of space.
There was no “before the Big Bang"—the Big Bang created both time and space as we know it.
Dark matter is a mysterious type of matter that doesn't interact with any form of electromagnetic radiation, i.e., light. Although we’ve never detected dark matter directly, a large amount of evidence points to its existence.
Just how quickly is the universe expanding? Cosmologists attempt to answer this question in terms of the Hubble Constant, but the exact value of this constant is still a topic of debate.
Is the universe infinite, or just really, really big? How can we know? To answer these questions, we examine the possible shapes of the universe.
Barring the Sun, the closest star to Earth is a triple system called Alpha Centauri, which is over four light years away.
Because black holes severely warp the fabric of spacetime, they have a curious effect on the passage of time as seen by an outside observer.
Black holes are singularities: points of infinitely small volume with infinite density. However, the amount of a mass concentrated in a black hole varies, and the mass determines how wide the black hole's sphere of influence is.
