Competing ideas abound for how Earth got its moon

Science News, April 2017

The moon’s origin story does not add up. Most scientists think that the moon formed in the earliest days of the solar system, around 4.5 billion years ago, when a Mars-sized protoplanet called Theia whacked into the young Earth. The collision sent debris from both worlds hurling into orbit, where the rubble eventually mingled and combined to form the moon.

New desalination tech could help quench global thirst

Science News, August 2016

The world is on the verge of a water crisis. Rainfall shifts caused by climate change plus the escalating water demands of a growing world population threaten society’s ability to meet its mounting needs. By 2025, the United Nations predicts, 2.4 billion people will live in regions of intense water scarcity, which may force as many as 700 million people from their homes in search of water by 2030. Those water woes have people thirstily eyeing the more than one sextillion liters of water in Earth’s oceans and some underground aquifers with high salt content.

Changing climate: 10 years after An Inconvenient Truth

Science News, April 2016

More than 25 years before the star-studded Los Angeles premiere of An Inconvenient Truth, glaciologist Lonnie Thompson was about as far away from the red carpet as possible. It was 1978, and high in the rugged Andes, Thompson and fellow scientists were witnessing the first glimpses of a pending worldwide disaster. Rising temperatures were melting ancient titans of ice and snow. Mammoth glaciers were disappearing at unprecedented rates and withering to the smallest sizes in millennia. The delicate balance of Earth’s climate was upset.

New fascination with Earth’s ‘Boring Billion’

Science News, October 2015

Earth’s long history starts with an epic preamble: A collision with a Mars-sized space rock rips into the young planet and jettisons debris that forms the moon. Over the next few billion years, plot twists abound. The oceans form. Life appears. Solar-powered microbes breathe oxygen into the air. Colossal environmental shifts reshape the planet’s surface and drive the evolution of early life.

A feature article on Earth's so-called boring billion, a seemingly uneventful time in the planet's history that's now the setting of a fierce debate between scientists over what delayed the rise of animals: evolution or the environment.

Ice particles shaped like lollipops fall from clouds

Science News, May 2017

Right now, somewhere in the world, it could be raining lollies. A 2009 research flight through clouds above the British Isles gathered ice particles with an unusually sweet look. Each millimeter-sized particle consisted of a stick-shaped piece of ice with a single water droplet frozen on the end, giving it the appearance of a lollipop. Atmospheric scientist Stavros Keppas of the University of Manchester in England and colleagues report the discovery of the atmospheric confections in a paper to be published in Geophysical Research Letters.

Crack in Antarctica’s Larsen C ice shelf forks

Science News, May 2017

The 180-kilometer-long crack threatening one of Antarctica’s largest ice shelves has branched out, new satellite observations reveal. The main rift in the Larsen C ice shelf hasn’t grown longer since February. But radar mapping shows that a second crack has split off from the main rupture like a snake’s forked tongue, members of the Antarctic research group Project MIDAS reported May 1. That second branch, which stretches around 15 kilometers, didn’t exist on radar maps taken six days earlier, the scientists say.

Here’s how an asteroid impact would kill you

Science News, May 2017

It won’t be a tsunami. Nor an earthquake. Not even the crushing impact of the space rock. No, if an asteroid kills you, gusting winds and shock waves from falling and exploding space rocks will most likely be to blame. That’s one of the conclusions of a recent computer simulation effort that investigated the fatality risks of more than a million possible asteroid impacts.

‘Fossil’ groundwater is not immune to modern-day pollution

Science News, April 2017

Groundwater that has lingered in Earth’s depths for more than 12,000 years is surprisingly vulnerable to modern pollution from human activities. Once in place, that pollution could stick around for thousands of years, researchers report online April 25 in Nature Geoscience. Scientists previously assumed such deep waters were largely immune to contamination from the surface.

‘River piracy’ on a high glacier lets one waterway rob another

Science News, April 2017

Ahoy! There be liquid booty on the move in the high mountains. Since May 2016, a channel carved through one of northwestern Canada’s largest glaciers has allowed one river to pillage water from another, new observations reveal. This phenomenon, almost certainly the result of climate change, is the first modern record of river piracy caused by a melting glacier, researchers report online April 17 in Nature Geoscience. Such piracy was rampant as the colossal ice sheets of the Last Glacial Maximum began shrinking around 18,000 years ago.

Pair of Supermassive Black Holes Discovered on a Collision Course

Simons Foundation, July 2019

Astronomers have spotted a distant pair of titanic black holes headed for a collision. Each black hole’s mass is more than 800 million times that of our sun. As the two gradually draw closer together in a death spiral, they will begin sending gravitational waves rippling through space-time. Those cosmic ripples will join the as-yet-undetected background noise of gravitational waves from other supermassive black holes.
