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)

CAPE CANAVERAL, Fla. (AP) — The Hubble Space Telescope has captured the best pictures yet of our newest interstellar visitor. This comet from outside our solar system is zooming by us at a blistering 110,000 mph (177,000 kph). Hubble caught some glam shots over the weekend from a distance of 260...

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) — 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...

FILE - In this Sunday, July 14, 2019, file photo, the sun sets behind telescopes at the summit of Mauna Kea. Scientists are expected to explore fundamental questions about our universe when they use a giant new telescope planned for the summit of Hawaii’s tallest mountain. That includes whether there’s life outside our solar system and how stars and galaxies formed in the earliest years of the universe. But some Native Hawaiians don’t want the Thirty Meter Telescope to be built at Mauna Kea’s summit, saying it will further harm a place they consider sacred. (AP Photo/Caleb Jones, File)

HONOLULU (AP) — Is there life on planets outside our solar system? How did stars and galaxies form in the earliest years of the universe? How do black holes shape galaxies? Scientists are expected to explore those and other fundamental questions about the universe when they peer deep into the night...

This image released by the Japan Aerospace Exploration Agency (JAXA) shows an explosive dropped from Hayabusa2 spacecraft to make a crater on the asteroid Ryugu Friday, April 5, 2019. Japan's space agency JAXA said its Hayabusa2 spacecraft successfully dropped the "small carry-on impactor" made of copper onto the asteroid and collect its underground samples to find possible clues to the origin of the solar system.
