From the moment that seven Earth-sized planets were discovered in orbit around TRAPPIST-1 -- an ultracool dwarf star located 39 light years away -- astronomers have been busy trying to learn everything they can about this intriguing star system, particularly its potential to foster life. Recently, an international team of scientists used the Hubble Space Telescope to assess the chances of water existing on these planets -- and the results are promising.

Video: We've all made a tiny ping-pong ball float on a hair dryer, but what YouTube's Veritasium is demonstrating here -- a giant Styrofoam ball floating on the side of a thin stream of water -- seems to contradict every scientific law governing our universe. But there is an explanation as to what's happening.
On Wednesday, Michigan's Attorney General announced it will charge Nick Lyon, the Health and Human Services Director, with involuntary manslaughter for his role in the Flint water crisis. During the crisis, caused in part by substandard water treatment, 100,000 residents were exposed to elevated levels of lead, a dangerous neurotoxin, and were at elevated risk for Legionnaire's disease, a waterborne illness linked to 14 deaths in the city since 2014.
Manufacturing 2,000 litres of drinkable water, extracted from the air (using renewable energy), at a cost of less than two cents per litre.
That's the challenge set to those entering the Water Abundance XPRIZE, where 98 teams from 25 countries will compete for the $1.75 million. Four Australian teams will take on the challenge, and we spoke to Hydro Harvest Operation (H20) about how they plan to win.
Our little red neighbour may be a rocky red wasteland now, but a lot of people think it was once an ocean-covered world just like our own. After scientists found some evidence of flowing water back in 2015, folks started to take these claims even more seriously. Heck, maybe Mars even supported life.
For decades, scientists have wondered if frost persists inside the dark and cold craters of the Moon's poles. The recent discovery of unusually bright areas near the Moon's south pole suggests this very well may be the case. But as a potential source of water for aspiring lunar colonists, the quantity of this surface frost may come as a disappointment.
Nutrition is a battlefield where everyone seems to have an opinion. Some of those opinions are science-based, and others are veiled quackery with little evidence to back them up. It can be frustrating if you're simply trying to stay healthy. Do you spend $4 on the expensive water bottle or just drink it from the tap? Is the science behind a product's claims valid?
It was a story that was too good to pass up. The Svalbard "doomsday" seed vault had flooded because of global warming-induced high temperatures melting the surrounding permafrost. But according to one of the vault's creators, the reports are pretty overblown and everything's fine. Well, the vault's fine. The apocalypse is still ticking along nicely.
Water has some special properties you've surely heard about in high school chemistry. Most notably, it sticks to itself really well. It beads together, looks like this in space, and climbs up plants' vascular systems, all thanks to hydrogen bonds. Now, scientists have figured out exactly how sticky those ubiquitous bonds are.
You might think space is the final frontier, but there's an entire alien world beneath the sea. Exploring the deepest abysses even looks a lot like exploring outer space. So, we set up some time with Fabien Cousteau, aquanaut, Jacques Cousteau's grandson, and arguably the ocean's biggest fan, to chat about what it's like. Cousteau organised a 31-day mission underwater to the Aquarius lab back in 2014.
Today, President Trump signed an executive order aimed at reworking Obama-era protections of clean water. The order asks for a revision of the 2015 Water of the US Act, a move likely to thrill Trump's supporters in the fossil fuel industry and big agriculture, and confuse just about everyone else. The order doesn't outright repeal WOTUS, it simply signals new EPA head Scott Pruitt to begin the process of revising and rewriting the law.
As if the ocean wasn't already full of nightmares, researchers at MIT have developed a soft and flexible robot made of hydrogel, a material composed mostly of water. The new bot is quick, strong and almost completely invisible when submerged, allowing it to snatch up fish before they even realise they're being tracked.
