In Jukkasjärvi, a village a few miles east of Kiruna, the proprietors of one hotel begin planning for a winter ice festival in March. That’s when they begin collecting some 5,000 tons of ice from the River Torne in order to prepare the Icehotel, the world’s coolest place to stay. Options for overnight stay include snow rooms, ice rooms, art suites, and the Northern Lights room, all of which range from about $300 to $900 per night. But the deluxe suite’s the only way to go. These rooms come with a critical amenity: heated ensuite bathrooms and saunas. Here: A man walks into a room in the Ice hotel in Jukkasjarvi, Sweden, December 16, 2015.

Today is what is known as the equilux and it happens when day and night are equal and occurs a few days before the spring equinox, and a few days after the autumn equinox. What appears to be a floating leaf is actually a stray sticking to a wet car windshield in a park in Scaggsville, Maryland on September 25, 2024. Today sunrise was at 7:02am and sunset took place at 7:02pm. The green and orange colored leaf (about half for each color) seems to represent the transition from Summer to Fall. (Photo by Michael S.
