CAPE CANAVERAL, Fla. (AP) — Saturn may have flown solo for billions of years — almost its entire existence — before getting its stunning set of rings, a new study suggests.
An Italian-led team reported Thursday in the journal Science that Saturn's primary rings appear to be just 10 million to 100 million years old. The gas giant Saturn, on the other hand, is 4.5 billion years old, like all the other planets in our solar system.
BEIJING (AP) — China's burgeoning space program achieved a lunar milestone on Thursday: landing a probe on the mysterious and misnamed "dark" side of the moon.
Exploring the cosmos from that far side of the moon, which people can't see from Earth, could eventually help scientists learn more about the early days of the solar system and maybe even the birth of the universe's first stars.
LAUREL, Md. (AP) — NASA's New Horizons spacecraft pulled off the most distant exploration of another world Tuesday, skimming past a tiny, icy object 4 billion miles from Earth that looks to be shaped like a bowling pin.
Flight controllers in Maryland declared success 10 hours after the high-risk, middle-of-the-night encounter at the mysterious body known as Ultima Thule on the frozen fringes of our solar system, an astounding 1 billion miles (1.6 billion kilometers) beyond Pluto.
WASHINGTON (AP) — Uranus is a lopsided oddity, the only planet to spin on its side. Scientists now think they know how it got that way: It was pushed over by a rock at least twice as big as Earth.
CAPE CANAVERAL, Fla. (AP) — Astronomers have spotted the farthest known object in our solar system — and they've nicknamed the pink cosmic body "Farout."
The International Astronomical Union's Minor Planet Center announced the discovery Monday.
WASHINGTON (AP) — NASA's Voyager 2 is now the second human-made object to zip away from the sun into the space between the stars.
Voyager 2 last month exited "this bubble that the sun creates around itself," longtime NASA mission scientist Ed Stone said Monday. The spacecraft is now beyond the outer boundary of the heliosphere, some 11 billion miles (about 18 billion kilometers) from Earth.
CAPE CANAVERAL, Fla. (AP) — In our solar system family, Mars is Earth's next-of-kin, the next-door relative that has captivated humans for millennia. The attraction is sure to grow with Monday's arrival of a NASA lander named InSight.
InSight should provide our best look yet at Mars' deep interior, using a mechanical mole to tunnel 16 feet (5 meters) deep to measure internal heat, and a seismometer to register quakes, meteorite strikes and anything else that might start the red planet shaking.
BERLIN (AP) — Final preparations were underway Friday for the launch of a joint mission by European and Japanese space agencies to send twin probes to Mercury, the closest planet to the sun.
An Ariane 5 rocket is scheduled to lift the uncrewed spacecraft into orbit from French Guiana shortly before midnight, the start of a seven-year journey to the solar system's innermost planet.
TOKYO (AP) — Japan's space agency is delaying a spacecraft touchdown on an asteroid because scientists need more time to find a safe landing site on the extremely rocky surface.
The spacecraft Hayabusa2 left Earth in 2014 and traveled 280 million kilometers (170 million miles) to the area of asteroid Ryugu, which it reached in June.
JACUMBA, Calif. (AP) — U.S. and Mexican authorities have discovered an incomplete, solar-powered tunnel connecting the two countries in a rugged, remote area east of San Diego.
CAPE CANAVERAL, Fla. (AP) — Astronomers may have found the first moon outside our solar system, a gas behemoth the size of Neptune.
Plenty of planets exist beyond our solar system, but a moon around one of those worlds has yet to be confirmed. Two Columbia University researchers presented their tantalizing evidence for a moon Wednesday.
First possible moon found beyond our solar system
TOKYO (AP) — A German-French observation device safely landed on an asteroid on Wednesday after a Japanese spacecraft released it as part of a research effort that could find clues about the origin of the solar system, Japanese space officials said.
The Japan Space Exploration Agency said the Mobile Asteroid Surface Scout, or MASCOT, was released from the unmanned spacecraft Hayabusa2 and successfully landed on the asteroid Ryugu.
CAPE CANAVERAL, Fla. (AP) — A scrawny dwarf planet nicknamed the Goblin has been discovered well beyond Pluto.
A round frozen world just 186 miles (300 kilometers) across, the Goblin was spotted by astronomers in 2015 around Halloween, thus its spooky name. But it wasn't publicly unveiled until Tuesday following further observations with ground telescopes.
TOKYO (AP) — A Japanese spacecraft released two small rovers on an asteroid on Friday in a mission that could provide clues to the origin of the solar system.
The Japan Space Exploration Agency said the two Minerva-II-1 rovers were lowered from the unmanned spacecraft Hayabusa2 to the asteroid Ryugu. The spacecraft arrived near the asteroid, about 280 million kilometers (170 million miles) from Earth, in June.
CAPE CANAVERAL, Fla. (AP) — A NASA spacecraft that explored Pluto has spotted its next target on the outskirts of our solar system.
NEW YORK (AP) — Astronomers are still finding moons at Jupiter, 400 years after Galileo used his spyglass to spot the first ones.
The latest discovery of a dozen small moons brings the total to 79, the most of any planet in our solar system.
CAPE CANAVERAL, Fla. (AP) — Last year's visitor from another star system — a cigar-shaped object briefly tumbling through our cosmic neck of the woods — has now been identified as a comet.
A European-led team makes the case in Wednesday's edition of the journal Nature.
Telescopes first spotted the mysterious red-tinged object last October as it zipped through the inner solar system. Since then, astronomers have flip-flopped between comet and asteroid for our first confirmed interstellar guest.
TOKYO (AP) — A Japanese space probe arrived at an asteroid Wednesday after a 3 1/2-year journey to undertake a first-ever experiment: blow a crater in the rocky surface to collect samples and bring them back to Earth.
The unmanned Hayabusa2 spacecraft reached its base of operations about 20 kilometers (12 miles) from the asteroid and some 280 million kilometers (170 million miles) from Earth, the Japan Aerospace Exploration Agency said.
DURHAM, N.H. (AP) — A team from the University of New Hampshire has been selected to be part of a NASA mission that seeks to study interstellar space.
The mission will help researchers better understand the boundary of the heliosphere, which acts as a bubble-like shield for the solar system from galactic cosmic radiation.
CAPE CANAVERAL, Fla. (AP) — Just months after the discovery of our first known interstellar visitor, it turns out there's another asteroid from yet another star system residing in our cosmic club in plain view.
Scientists reported Monday that this interstellar resident is an asteroid sharing Jupiter's orbit but circling in the opposite direction.
FLAGSTAFF, Ariz. (AP) — A five-person team of scientists at Lowell Observatory in Flagstaff helps maintain a giant database of the orbits of all 775,092 known asteroids in the solar system.
BERLIN (AP) — Fragments of a meteorite that fell to Earth about a decade ago provide compelling evidence of a lost planet that once roamed our solar system, according to a study published Tuesday.
Researchers from Switzerland, France and Germany examined diamonds found inside the Almahata Sitta meteorite and concluded they were most likely formed by a proto-planet at least 4.55 billion years ago.
CAPE CANAVERAL, Fla. (AP) — Our first known interstellar visitor likely came from a two-star system.
That's the latest from astronomers who were amazed by the mysterious cigar-shaped object, detected as it passed through our inner solar system last fall.
CAPE CANAVERAL, Fla. (AP) — There's a new nickname for the icy world next up for the spacecraft that explored Pluto: Ultima Thule.
NASA's New Horizons spacecraft is headed toward a New Year's Day encounter with this mysterious object or two, 1 billion miles beyond Pluto on the fringes of our solar system.
WASHINGTON (AP) — In a story Jan. 17 about meteors, The Associated Press reported erroneously the size of asteroids that scientists hope to be able to deflect from Earth's path in the future. They want to have a defensive system for asteroids larger than 165 feet (50 meters), not 30 miles (50 kilometers).
A corrected version of the story is below:

CAPE CANAVERAL, Fla. (AP) — A record-tying eighth planet has been found in a faraway solar system, matching our own in number.
Even more amazing, machines and not humans made the discovery. NASA joined with Google on Thursday to announce the finding.
CAPE CANAVERAL, Fla. (AP) — A newly discovered object from another star system that's passing through ours is shaped like a giant pink fire extinguisher.
That's the word this week from astronomers who have been observing this first-ever confirmed interstellar visitor.
"I'm surprised by the elongated shape — nobody expected that," said astronomer David Jewitt of the University of California, Los Angeles, who led the observation team that reported on the characteristics.
CAPE CANAVERAL, Fla. (AP) — Heads up, armchair travelers.
NASA is seeking a nickname for a tiny, icy world on the edge of the solar system that's the next destination for New Horizons, the spacecraft that surveyed Pluto.
New Horizons whipped past Pluto two years ago. Now it's headed for 2014 MU69 — gobbledygook to even the most die-hard scientists.
