Asteroid Flyby

A jumbo-jet-size asteroid gave Earth a close shave yesterday, whizzing past our planet at a safe distance of 126,000 miles (203,000 kilometers) — or about half the distance between Earth and the moon.The asteroid, which is officially designated 2010 WC9, made its closest approach at 6:05 p.m. EDT (2205 GMT) while traveling at a speed of 28,655 mph (46,116 km/h).

Monster ocean wave sets southern hemisphere record

Scientists have recorded what is believed to be the largest wave ever in the southern hemisphere, a 23.8 metre monster the height of an eight-floor building.

A buoy recorded the wave on Tuesday during a ferocious storm in the notoriously wild Southern Ocean near Campbell Island, some 700 kilometres south of New Zealand, research body MetOcean Solutions said.

Senior oceanographer Tom Durrant said it wiped out the previous southern-hemisphere record of 22.03 metres recorded in 2012.

Durrant added that even bigger waves topping 25 metres were probably whipped up by the storm, which tracked east through the area on Tuesday, but the buoy was not in the best place to record them. He said the buoy, installed in March to measure the extreme conditions in the Southern Ocean, also only recorded for a 20-minute burst every three hours to conserve its batteries.

Eta Aquarid meteor shower

The 2018 Eta Aquarids meteor shower will peak this weekend, with a clear, dark sky forecast for a few major South American cities.

As the Earth passes through the debris trail left behind by Halley’s Comet, the Southern Hemisphere will experience the most active meteor shower activity. Up to 40 meteors are expected to streak across the sky every hour – or one every 90 seconds. Those along the West Coast of the continent will have a good shot at seeing some meteors as well.

NASA scientists flying over the Arctic earlier this month spotted strange shapes out the window, but they aren’t sure what caused them.

Three holes dot the sea ice, seen from the window of a NASA aircraft in the photo above, taken April 14. They’re clustered together, each surrounded by one or two radiating layers of ridged, textured ice, almost as if a batch of archery targets had melted and gone lopsided. All around them are bumpy formations that mean the ice is thin and relatively new.

It’s possible, NASA wrote, that some large mammal took advantage of that thin ice to poke holes through it to breathe.Ring sealsand harp seals are both known to poke holes through the ice that look somewhat similar to this.

Asteroid Close Shave

Earth received a cosmic close shave on Sunday (April 15) when a football field-size boulder passed by at half the moon’s distance from our planet. Named 2018 GE3, the asteroid was detected only a few hours before its flyby, spotted by the automated Catalina Sky Survey.

At its closest approach, at 2:41 a.m. EDT (0641 GMT), 2018 GE whipped by Earth at a distance of only 119,500 miles (192,300 kilometers), according to EarthSky. That’s a close call, given that the asteroid has an estimated diameter of 157 to 361 feet (48 to 110 meters), making it much larger than the cosmic object that exploded over Chelyabinsk, Russia, in 2013.

An image of an incredibly rare, 65-foot-tall (20 meters) lava-dome fountain rising above the lava fields in Hawaii.

Posted by the U.S. Geological Survey (USGS), the image was taken in 1969, during the Mauna Ulu eruption, which lasted (on and off) for an astonishing five years, from May 1969 until July 1974.

Normally, volcanoes erupt lava in powerful jets that look like fountains gone wild. But in this photo the lava spurted out symmetrically, forming an unusual lava-dome fountain.
