Hera team congratulates NASA asteroid impactors

ESA’s Hera mission team congratulates their counterparts in NASA’s DART mission team for their historic impact with the Dimorphos asteroid. Moving at 6.1 km per second, the car-sized Double Asteroid Redirect Test spacecraft struck the 160-m diameter asteroid at 01:15 CEST (00:15 BST) in the early hours of Tuesday morning, in humankind’s first test of the ‘kinetic […]

DART’s Impact with Asteroid Dimorphos (Official NASA Broadcast)

Countdown to impact as NASA’s Double Asteroid Redirection Test (DART) attempts humanity’s first-ever test of planetary defense! The DART spacecraft will intentionally crash into asteroid Dimorphos at 4:14 p.m. PT on Monday, September 26, 2022 to see if kinetic force can change its orbit. Why? If this test is successful, the same technique could be […]

How global warming affects astronomical observations

September 22, 2022 – Astronomical observations from ground-based telescopes are sensitive to local atmospheric conditions. Anthropogenic climate change will negatively affect some of these conditions at observation sites around the globe, as a team of researchers led by the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS reports. The quality […]

Researchers have discovered a 380-million-year-old heart – the oldest ever found

Researchers have discovered a 380-million-year-old heart – the oldest ever found – alongside a separate fossilised stomach, intestine and liver in an ancient jawed fish, shedding new light on the evolution of our own bodies. The new research, published today in Science, found that the position of the organs in the body of arthrodires – an […]

Pollution exposure in infancy alters gut microorganisms, may boost disease risk

September 6, 2022 – Exposure to air pollution in the first six months of life impacts a child’s inner world of gut bacteria, or microbiome, in ways that could increase risk of allergies, obesity and diabetes, and even influence brain development, suggests new CU Boulder research. The study, published this month in the journal Gut Microbes, is the […]

WMO predicts first “triple-dip” La Niña of the century

Geneva, 31 August 2022 – It is likely that the protracted La Niña event will last until at least the end of the year, becoming this century’s first “triple-dip“ La Niña, spanning three consecutive northern hemisphere winters (southern hemisphere summers), according to a new update from the World Meteorological Organization. The WMO El Niño/La Niña […]

Hidden Microearthquakes Illuminate Large Earthquake-Hosting Faults in Oklahoma and Kansas

Using machine learning to sift through a decade’s worth of seismic data, researchers have identified hundreds of thousands of microearthquakes along some previously unknown fault structures in Oklahoma and Kansas. The newly identified microearthquakes allowed the seismologists to map and measure earthquake clusters in the region, which has experienced unusual levels of seismicity due to […]

Scientists have calculated what can unbalance El Niño

Physicists and mathematicians of the Ural Federal University (UrFU) have calculated how external factors affect the behavior of El Niño – atmospheric and oceanic processes in the Pacific region. In the mathematical model, they accounted for wind, humidity, temperature, ocean currents, and other parameters that can lead to unpredictable El Niño results. This is a […]

New model developed to predict landslides along wildfire burn scars

A wildfire followed by an intense rainstorm is often a recipe for disaster. Without vegetation to cushion rainfall, water runoff can turn into a fast-moving, highly destructive landslide, called a “debris flow,” which often has the power to wipe out cars, homes and highways — sometimes resulting in casualties. Northwestern University researchers supported by the U.S. National […]

How the Earth is Changing

Climate change is a complicated phenomenon with a variety of both abrupt and gradual effects that scientists are working hard to uncover. Emerging findings on how various ecosystems are responding to a changing climate, stemming from long-term research conducted through the National Science Foundation’s 40-year-old Long-Term Ecological Research (LTER) program, have now been published in […]

Mountain events could improve safety with ultra-high resolution weather models

In late May of 2021, 172 runners set out to tackle a 100-kilometer (62-mile) ultramarathon in northwestern China. By midday, as the runners made their way through a rugged, high-elevation part of the course, temperatures plunged, strong winds whipped around the hillslopes and freezing rain and hail pummeled the runners. By the next day, the […]

Risk of death rises as climate change causes nighttime temperatures to climb

Excessively hot nights caused by climate change are predicted to increase the mortality rate around the world by up to 60% by the end of the century, according to a new international study that features research from the UNC Gillings School of Global Public Health. Ambient heat during the night may interrupt the normal physiology […]

Tonga Eruption Blasted Unprecedented Amount of Water Into Stratosphere

The huge amount of water vapor hurled into the atmosphere, as detected by NASA’s Microwave Limb Sounder, could end up temporarily warming Earth’s surface. When the Hunga Tonga-Hunga Ha’apai volcano erupted on Jan. 15, it sent a tsunami racing around the world and set off a sonic boom that circled the globe twice. The underwater eruption in […]
