CAPE CANAVERAL, Fla. (AP) — A Mercury-bound spacecraft swooped past Earth on Friday, tweaking its roundabout path to the solar system’s smallest and innermost planet. Launched 1 1/2 years ago, Europe and Japan’s BepiColombo spacecraft passed within 8,000 miles (12,700 kilometers) of Earth. The...

This Jan. 1, 2019 image from NASA shows Arrokoth, the farthest, most primitive object in the Solar System ever to be visited by a spacecraft. Astronomers reported Thursday, Feb. 13, 2020 that this pristine, primordial cosmic body photographed by the New Horizons probe is relatively smooth with far fewer craters than expected. It's also entirely ultrared, or highly reflective, which is commonplace in the faraway Twilight Zone of our solar system known as the the Kuiper Belt.

CAPE CANAVERAL, Fla. (AP) — NASA's space snowman is revealing fresh secrets from its home far beyond Pluto. More than a year after its close encounter with the snowman-shaped object, the New Horizons spacecraft is still sending back data from more than 4 billion miles (6.4 billion kilometers) away...

STOCKHOLM (AP) — An astronomer who shares this year's Nobel physics prize for discovering a planet outside the Earth's solar system is taking issue with people who shrug off climate change on the grounds that humans will eventually leave for distant planets. Didier Queloz was one of several Nobel...

This Oct. 12, 2019 photo made available by NASA shows the comet 2I/Borisov, seen by the Hubble Space Telescope. It’s the second known interstellar visitor to swoop through our backyard. An amateur astronomer from Crimea, Gennady Borisov, discovered the comet in August, two years after the first alien guest, a cigar-shaped rock, popped up. (NASA, ESA, D. Jewitt (UCLA) via AP)

This combination of Oct. 8, 2019, photos shows the Nobel Prize winners in Physics, from left, James Peebles in Princeton, N.J., Didier Queloz in London and Michel Mayor in Madrid. Peebles, an emeritus professor at Princeton University, won for his theoretical discoveries in cosmology. Swiss star-gazers Mayor, and Queloz, both of the University of Geneva, were honored for finding an exoplanet — a planet outside our solar system — that orbits a sun-like star, the Nobel committee said.

CAPE CANAVERAL, Fla. (AP) — The solar system has a new winner in the moon department. Twenty new moons have been found around Saturn, giving the ringed planet a total of 82, scientists said Monday. That beats Jupiter and its 79 moons. "It was fun to find that Saturn is the true moon king," said...

CAPE CANAVERAL, Fla. (AP) — The solar system may have another foreign guest. NASA and the European Space Agency say a newly discovered comet zooming toward the sun is likely from another star. Astronomers said Thursday it's traveling 93,000 mph (150,000 kph), so fast it likely originated outside...

CAPE CANAVERAL, Fla. (AP) — In a tantalizing first, scientists have discovered water at a planet outside our solar system that has temperatures suitable for life. London researchers announced Wednesday they've found water vapor in the atmosphere of a planet 110 light-years away. This so-called...

Astronomers across 11 observatories on Hawaii’s tallest mountain have cancelled more than 2,000 hours of telescope viewing over the past four weeks because a protest blocked a road to the summit. Astronomers said Friday, Aug. 9, 2019, they will attempt to resume observations but in some cases won’t be able to make up the missed research. (AP Photo/Caleb Jones, File)

HONOLULU (AP) — Asteroids, including those that might slam into Earth. Clouds of gas and dust on the verge of forming stars. Planets orbiting stars other than our own. This is some of the research astronomers say they have missed out on at 11 observatories on Hawaii's tallest mountain as a protest...
