Eclipses come in many forms
Eclipses are one of nature’s most awesome spectacles, and scientists have learned a lot by observing them and related celestial alignments — occultations and transits.

Cosmic mystery: Why are many galaxies dark?
Dark galaxies went unnoticed until 2015. Since then, scientists have now found more than 1,000 — and there may be many, many more.

Analyze This: The masses of planets
Scientists discovered a solar system with planets that are similar in size and mass to Earth. Using data, we take a closer look at that similarity.

Cool Jobs: Reaching out to E.T. is a numbers game
From figuring out if we’re alone in the universe, to writing messages to aliens, scientists use math in many ways in their search for extraterrestrial intelligence.

Scientists Say: Dwarf planet
Dwarf planets are distinct from the full-size models. A little too small, they also have a lot of space stuff filling their path around the sun.

Cool Jobs: A world aglow
Three scientists probe how the natural world makes light, in hopes of using this information to design new and better products.

Star caught passing gas before exploding
Stars can become unstable as they near death, a new study suggests. Some may even spew gas for a year or so before they explode.

Scientists Say: Goldilocks zone
Not too hot, not too cold. Just right. This is the region around a star where water could be a liquid, instead of a solid or gas.

New solar system found to have 7 Earth-size planets
A neighboring star system hosts seven Earth-like planets. Especially surprising: Three of those planets appear to reside in a zone that could support life as we know it.

Strange X-rays point to possible ‘dark’ matter
Scientists have been looking for “dark” matter. It’s supposed to make up most of the universe — but it’s also invisible. X-rays may now point to where some of this weird stuff is.

Cool Jobs: Probing Pluto
The New Horizons mission captivated the world as it flew by Pluto. Here are some of the people who made that possible.

Rivers of stars flow between ‘clouds’ orbiting the Milky Way
Two streams of stars flow between dwarf galaxies known as the Magellanic Clouds. This new finding could give clues to the structure of our Milky Way galaxy.
