A research team from ETH Zurich and the Max Planck Institute for Solar System Research in Göttingen counted over 136,000 rockfalls on the moon caused by asteroid impacts. Even billions of years old landscapes are still changing.

In October 2015, a spectacular rockfall occurred in the Swiss Alps: in the late morning hours, a large, snow-covered block with a volume of more than 1500 cubic meters suddenly detached from the summit of Mel de la Niva. It fell apart on its way downslope, but a number of boulders continued their journey into the valley. One of the large boulders came to a halt at the foot of the summit next to a mountain hut, after traveling more than 1.4 kilometers and cutting through woods and meadows.

On the moon, time and again boulders and blocks of rock travel downslope, leaving behind impressive tracks, a phenomenon that has been observed since the first unmanned flights to the moon in the 1960s. During the Apollo missions, astronauts examined a few such tracks on site and returned displaced rock block samples to Earth. However, until a few years ago, it remained difficult to gain an overview of how widespread such rock movements are and where exactly they occur.

The asteroid is estimated to be 1,100 ft. in diameter, while the Empire State Building stands at approximately 1,400 ft. tall.

Imagine Yankee Stadium or Citi Field cruising by Earth in a giant foul-ball flyby. That’s what’s set to happen this weekend when an asteroid the size of the Empire State Building tumbles through space uncomfortably close – but not close enough to hurt.

But it may be taller than the Empire State Building, which is 1,454 feet tall. The asteroid is estimated to be between 820 feet and 1,870 feet in diameter.

The asteroid was first spotted nearly two decades ago and is called 2002 NN4.

With North Korean leader Kim Jong-un pulling back out his nuclear card for the first time since 2018, a very natural and perhaps even urgent question is, what next? There are signs that the North is getting closer to unveiling its strategic weapon promised by Kim at the end of last year. But with the U.S. constrained and South Korea committed to global sanctions, there’s no sign of a dialogue breakthrough. We could be about to witness Pyongyang’s new way.

RUSSIA plans to hold more than 100 military drill this summer as Vladimir Putin ramps up his nation’s war readiness.

73 years ago, the same scientists who had helped to begin the atomic age set a “doomsday clock” for humanity. It first appeared on the cover of the June 1947 issue of the Bulletin of the Atomic Scientists as a dire warning about the nuclear rivalry between the U.S. and the Soviet Union. At that moment, the Bulletin estimated that we stood at about 7 minutes to midnight, which represented nuclear apocalypse.

The Doomsday Clock wasn’t – and still isn’t – a precise countdown to the end of all things. It’s a metaphor for how dangerous the global situation seems to be at a given moment, in the very well-informed but also subjective opinion of the Bulletin’s board of directors. In June 1947, things looked dire. The U.S. had dropped a pair of atomic bombs on Japan less than two years before; when the Bulletin of the Atomic Scientists first published the Doomsday Clock image, researchers were still studying the aftermath of those bombs. Meanwhile, the Soviet Union was hard at work on its own atomic program, and was just a couple of years away from testing its first atomic bomb in 1949.

Through the Cold War and in the decades since, the clock’s minute hand has moved about two dozen times. In September 1953, it stood at two minutes to midnight, following Russia’s August 1953 hydrogen bomb test – which in turn had followed a U.S. hydrogen bomb test in November 1952. Those tests meant the two feuding superpowers each had much more powerful new weapons with which to destroy each other; the tests also heightened the sense of life-or-death competition that made it more likely that someone would decide to use those terrible new bombs.
