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...

In this composite image provided by NASA, the planet Mercury passes directly between the sun and Earth on May 9, 2016 in a transit which lasted seven-and-a-half-hours. On Monday, Nov. 11, 2019, Mercury will make another transit, visible from the eastern U.S. and Canada, and all Central and South America. The rest of North America, Europe and Africa will catch part of the action. Asia and Australia will miss out. (NASA's Goddard Space Flight Center/SDO/Genna Duberstein via AP)

CAPE CANAVERAL, Fla. (AP) — Mercury is putting on a rare celestial show next week, parading across the sun in view of most of the world. The solar system's smallest, innermost planet will resemble a tiny black dot Monday as it passes directly between Earth and the sun. It begins at 7:35 a.m. EST...

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.
