This Stupendous Crater on Mars Looks Eerily Like a Tree Stump

You might be forgiven for thinking the above picture is the stump of a tree. Shift your perspective a little, however, and the truth becomes clear: What you’re looking at is much bigger than any tree – a concave depression on the surface of Mars, gouged out by a massive impact.   The rings radiating … Read more

Scientists Solve The Century-Old Mystery of Why This Special Insect Can Float in Water

Apart from fish, scientists have found only one other animal that can regulate its buoyancy in the water using swim bladders, and it’s probably not what you were expecting. The phantom midge is a type of lake fly (genus Chaoborus), but before it can take to the air, its larvae must first grow up in the … Read more

Glacier Lakes Make Permanent Ice Disappear Over Twice as Fast, Study Reveals

Glaciers are retreating faster globally due to climate change but they melt more quickly when they flow into a lake than when they end on land, with consequences for water supplies, a new study found on Thursday.   The Swiss-funded study is the first large-scale, detailed analysis of the phenomenon in mountain glaciers and could … Read more

Water on Mars may have flowed for a billion years longer than thought

Observations by a long-running Mars mission suggest that liquid water may have flowed on the Red Planet as little as 2 billion years ago, much later than scientists once thought. Scientists charted the presence of chloride salt deposits left behind by flowing water using years of data from NASA’s Mars Reconnaissance Orbiter (MRO), which has … Read more

‘Killer Lake’ in Africa Looks Like Paradise, But It’s Hiding a Deadly Secret

The engineers aboard the floating power station on Lake Kivu could only watch nervously as the volcano in the distance erupted violently, sending tremors rumbling through the water beneath them.   It was not the lava shooting from Mount Nyiragongo last May that spooked them, but the enormous concentrations of potentially explosive gases within Kivu, … Read more

Tonga Eruption Was Equivalent to ‘100s of Hiroshima Bombs’, Says NASA

The volcanic eruption in the South Pacific Kingdom of Tonga peaked on January 15 with more explosive force than 100 simultaneous Hiroshima bombs, NASA scientists reported on Monday 24 January.   Using a combination of satellite and surface-based surveys, researchers calculated the explosive power of the volcano based on the amount of rock that was removed during the blast from the … Read more

Mysterious Signal of Hidden Lakes on Mars May Not Be What We Thought

The likelihood of lakes of liquid water hidden under Mars‘ southern polar ice cap is receding before our very eyes. Last year, a paper found that temperatures were likely far too cold for water to remain unfrozen in the region. Now, a new study has found that the radar signal interpreted as liquid water was … Read more

Mars water: Spots at south pole thought to be lakes could be volcanic rock

Radar images of Mars’s southern ice cap indicated that there could be a lake there – but a new set of simulations hints that it could be volcanic rock instead Space 24 January 2022 By Leah Crane The icy cap over Mars’s south pole, photographed by Mars Express ESA/DLR/FU Berlin / Bill Dunford There may … Read more

Climate Change Could Open Up ‘Rivers in The Sky’ Over East Asia

We know that the climate crisis is already having a profound effect on global weather systems, altering temperatures, rainfall, wind patterns, and more – and a new study predicts likely deluges over the mountainous parts of East Asia in the future.   The pouring rain will be brought on by atmospheric rivers, scientists predict. These … Read more

Antarctic ‘Megaberg’ Released 152 Billion Tons of Freshwater Just Before Melting

Scientists have been keeping a close eye on the ‘megaberg’ designated as A68a since it split off from Antarctica back in July 2017 – and new research highlights just how much freshwater it’s released into the ocean during its late melting process.   Satellite monitoring systems indicate that for three months at the end of its … Read more
