The Hubble Space Telescope has spotted clouds and storms on the solar system's ice giants.
Naming features on other worlds is a trickier issue than you might think.
Senegal has made great strides in astronomy and planetary sciences in recent years.
Astronomers are excited about sub-surface oceans in the solar system, as they may support life. Now Pluto joins the club.
Trapped gas could be tainting the north pole of Pluto's moon Charon dark red.
After last summer's Pluto flyby, the New Horizons spacecraft started sending data back to Earth – at 2 kilobits per second. Here's some of what scientists have learned so far from that rich, slow cache.
From a flyby of Pluto to the search for extrasolar planets and gravitational waves, 2015 was a monumental year for space news.
Prepare to be amazed ...
2015 was a year where we expanded our view of the universe, embraced new technologies and got a hint of the profound changes to come.
From a mysterious haze to strange nitrogen snowfall, the latest pictures of Pluto pose many new questions.
New Year's resolutions are one thing. But what does it take to devote your life to a work goal with such a long time horizon you might never reach it in your lifetime?
Space scientists have a busy decade ahead with plans to visit Jupiter, Mars, Mercury and other interplanetary bodies all on the cards.
In the long lead-up to our ultimate flyby of Pluto, space science has reconfigured our notions of what it means to be a solar system, a planet, a world.
The existence of a "Planet X" in the outer solar system was the subject of great speculation, and was finally settled with the discovery of Pluto in 1930.
From Twinkle Twinkle to Space Odyssey and beyond, humans have always turned to music to help deal with the profoundly confronting enormity of the cosmos. Is that a match made in the heavens?
Photos from the spacecraft's close approach are dazzling. They and other data from the mission will fill in some of the blanks about Pluto and provide a snapshot of the infant solar system.
What can the data from New Horizons tell us about the dwarf planet's five moons?
Lack of impact craters intrigues space experts who say it suggests the dwarf planet may be geologically active.
New Horizons mission members have worked on the project for even longer than it's taken the spacecraft to get to Pluto. They've planned, built and researched – and now their efforts are paying off.
