• The US Geological Survey documented unusual seismic activity patterns beneath Yellowstone National Park over the past 72 hours, including 127 small earthquakes concentrated in a previously stable subsurface region. • Monitoring stations recorded magnitude 2.0-3.8 events with distinct directional propagation, suggesting possible magma chamber adjustments rather than typical tectonic shifts, announced April 21 by USGS geophysicists. • Scientists emphasize current volcanic threat levels remain low based on gas emissions and ground deformation data, though real-time monitoring has been intensified as a precautionary measure.

Covid, light pollution regulations and faltering global economy affect location and intensity of brightnessEarth continues to get brighter every year, researchers have found, but the location and intensity of the progression has become increasingly volatile because of Covid-19, regulations on light pollution, and a faltering global economy.Nasa-funded researchers at the University of Connecticut (UConn) studied more than 1.1m satellite images taken over a nine-year period to establish that the planet’s artificial light increased by a net 16% between 2014 and 2022.

• NASA's Artemis II mission surpassed the Apollo 13 record on April 6, 2026, at 1:57 p.m. EDT, reaching beyond 248,655 miles (400,171 km) from Earth as the Orion capsule 'Integrity' looped around the moon's far side. • The mission will peak at 252,760 miles (406,777 km), breaking the prior record by 4,100 miles (6,600 km) during its six-hour lunar flyby, marking the first crewed deep-space mission since Apollo. • This milestone validates life-support systems, navigation, and thermal protection for humans, paving the way for sustained lunar presence under the US Artemis program.

Capsule’s engine fires up for six minutes, putting crew on track to reach farthest distance travelled by humans in spaceThe four astronauts on the Artemis II mission are approaching 100,000 miles from Earth as they head towards the moon, putting them on track to reach the farthest distance humans have ever travelled into space.The crew have left Earth’s orbit and fired their engines on Thursday for a “translunar injection”, sending the Orion capsule on its trajectory towards the moon.

Nasa mission enters its second day, with crew hoping to become first people to get close to the moon in over 50 yearsFour astronauts are preparing to leave Earth’s orbit and slingshot towards the moon as Nasa’s Artemis II mission enters its second day.The high-stakes 10-day voyage will mark the first time in half a century that humans leave space close to Earth and return to the vicinity of the moon. It is a crucial test of Nasa’s ambition to land humans back on the lunar surface this decade, and stay there permanently. Continue reading...

Human Rights Watch and others say they have documented use of weapon in civilian areas, which some argue is illegalWhen the M825-series 155mm artillery projectile airbursts, expelling its felt wedges containing white phosphorus, it leaves a distinctive knuckle-shaped plume. That is how Human Rights Watch (HRW) researchers said they were able to verify that Israel was again using the notorious weapon over south Lebanon, reigniting accusations that it is breaking the laws of war.The New York-based rights group said it had verified and geolocated eight images showing airburst white phosphorus munitions exploding over residential areas in the southern Lebanese town of Yohmor in the opening days of Israel’s assault during the war on Gaza.

• Scientists from Oregon State University and the Potsdam Institute for Climate Impact Research have identified 16 'tipping elements' across Earth's systems, including the Greenland Ice Sheet, Amazon rainforest, and Atlantic Ocean's overturning current, that could trigger a 'hothouse Earth trajectory' if pushed past critical temperature thresholds. • Atmospheric CO2 has reached 422.5 parts per million, about 50% higher than pre-industrial levels, with researchers warning that triggering one tipping element could push others closer to their own thresholds in a cascading effect. • The study, published in One Earth, distinguishes between a 'hothouse trajectory'—a direction of travel that could theoretically be interrupted—and a 'hothouse state,' where the planet would be locked into extreme, sustained heat and seas many meters higher.

• Human-driven climate change is lengthening Earth's day by 1.33 milliseconds per century, the fastest rate in 3.6 billion years, due to melting ice redistributing mass toward the equator. • ETH Zurich researchers Mostafa Kiani Shahvandi and Benedikt Soja used foraminifera fossils to confirm this anomalous effect outpaces historical changes, including El Niño winds. • Projections show a 2.62 milliseconds-per-century increase by 2080 under high-emissions scenarios, impacting precise timekeeping in spacecraft, computing, and geodesy instruments.

Looking for molecular evidence of life on other worlds is tricky, but a test based on the reactivity of carbon compounds could be a useful indicator

Photographer Jonas Kako travelled to Greenland to explore how mining for the rare earth elements and minerals that are vital for new green technologies is impacting locals

Since 2014, the planet has been warming by about 0.36°C per decade, according to an analysis of five temperature datasets, raising fears that climate tipping points could be crossed earlier than expected

The dinosaurs were wiped out by an asteroid, but does that mean we risk suffering the same fate - and should you be worried about the possibility? Leah Crane sets the matter straight

A study analyzing North China Craton rocks reveals tectonic uplift from early supercontinent Columbia formation erased over a billion years of Earth's history, creating the Great Unconformity observed globally. Researchers found 13 kilometers of erosion and 400 degrees of cooling predating Cryogenian glaciations by analyzing zircon and monazite minerals across five sites. Coauthor Nicholas Christie-Blick noted, 'If glaciation had been the dominant driver, you’d expect a clear pulse of erosion at the time of the Cryogenian ice ages. We don’t see that pattern.' Published in PNAS, this challenges Snowball Earth theory and refines plate tectonics models.
