Airport Runway Names Shift with Magnetic Field
For example, the Fairbanks International Airport in Alaska renamed runway 1L-19R to 2L-20R in 2009 when magnetic north shifted enough to mandate a change. And the airport operators know—from NCEI’s World Magnetic Model (WMM) and other sources—that they’ll likely need to update the name again in 2033…
Lunar Eclipses – 2021-2030
Eclipses recur over the Saros cycle, a period of approximately 18 years 11 days.
The saros is a period of exactly 223 synodic months, approximately 6585.3211 days, or 18 years, 10, 11, or 12 days (depending on the number of leap years), and 8 hours, that can be used to predict eclipses of the Sun and Moon.

Plastic Bag Found at the Bottom of World’s Deepest Ocean Trench
A recent study revealed that a plastic bag, like the kind given away at grocery stores, is now the deepest known piece of plastic trash, found at a depth of 36,000 feet inside the Mariana Trench. Scientists found it by looking through the Deep-Sea Debris Database, a collection of photos and videos taken from 5,010 dives over the past 30 years that was recently made public.
The strange story of Australia’s wild camel
I looked online that evening to make sure I hadn’t been hallucinating. Camels, you understand, are about as Australian as polar bears. Or rather, that used to be true. It turned out I’d just been ill-informed – and to a colossal degree. The outback was, and is, home to an extraordinary number of wild camels.

Quake
The April 2015 Nepal earthquake (Nepali: विसं २०७२ को महाभूकम्प) (also known as the Gorkha earthquake) killed over 8,000 people and injured more than 21,000. It occurred at 11:56 Nepal Standard Time on 25 April, with a magnitude of 7.8Mw or 8.1Ms and a maximum Mercalli Intensity of IX (Violent). Its epicenter was east of Gorkha District at Barpak, Gorkha, and its hypocenter was at a depth of approximately 8.2 km (5.1 mi). It was the worst natural disaster to strike Nepal since the 1934 Nepal–Bihar earthquake.
The earthquake triggered an avalanche on Mount Everest, killing 21, making April 25, 2015 the deadliest day on the mountain in history. The earthquake triggered another huge avalanche in the Langtang valley, where 250 people were reported missing.
