As satellites crawl across the sky, they reflect light from the sun back down to Earth, especially during the first few hours after sunset and the first few hours before sunrise. As more companies launch networks of satellites into low-Earth orbit, a clear view of the night sky is becoming rarer. Astronomers, in particular, are trying to find ways to adapt.

A charred chunk of space junk found jutting from a paddock by an Australian sheep farmer was confirmed to be part of one of Elon Musk's SpaceX missions by authorities Thursday.
The ethereal-looking debris, believed to have plummeted to Earth on July 9, was found last week in Dalgety - a remote area near Australia's Snowy Mountains, about five hours' drive southwest of Sydney.

When the Hunga Tonga-Hunga Ha'apai volcano erupted on Jan. 15, it sent a tsunami racing around the world and set off a sonic boom that circled the globe twice. The underwater eruption in the South Pacific Ocean also blasted an enormous plume of water vapor into Earth's stratosphere - enough to fill more than 58,000 Olympic-size swimming pools.

Much ado was made about the Higgs boson when this elusive particle was discovered in 2012. Though it was touted as giving ordinary matter mass, interactions with the Higgs field only generate about 1 percent of ordinary mass.

A red ball of spicy fire with luminous patches glowing menacingly against a black background.
This, prominent French scientist Etienne Klein declared, was the latest astonishing picture taken by the James Webb Space Telescope of Proxima Centauri, the closest star to our Sun.
Fellow Twitter users marveled at the details on the picture purportedly taken by the telescope, which has thrilled the world with images of distant galaxies going back to the birth of the universe.
"This level of detail... A new world is revealed every day," he gushed.
But in fact, as Klein later revealed, the picture was not of the intriguing star just over four light-years from the Sun but a far more modest slice of the lip-sizzling Spanish sausage chorizo.
