Earth"s Wobble Wreaks Havoc on Astronomers--And Astrologers, Too
Our planet’s precession is scarcely noticeable during anyone’s lifetime, but across history, it has had enormous effects.....»»
James Webb observes extremely hot exoplanet with 5,000 mph winds
Astronomers using the James Webb telescope have modeled the weather on a distant exoplanet, revealing winds whipping around at speeds of 5,000 miles per hour......»»
A clock in the rocks: What cosmic rays tell us about Earth"s changing surface and climate
How often do mountains collapse, volcanoes erupt or ice sheets melt?.....»»
The COVID-19 pandemic changed our patterns and behaviors, which in turn affected wildlife
The Earth now supports over eight billion people who collectively have transformed three-quarters of the planet's land surface for food, energy, shelter and other aspects of the human enterprise......»»
Life"s insiders: Decoding endosymbiosis with mathematics
Endosymbiosis, the intimate and long-term relationship where one organism lives inside another, is a cornerstone of life as we know it, and a key to the emergence of complex life on Earth. Many of the mysteries surrounding endosymbiosis are difficult.....»»
Fluidic telescope (FLUTE): Enabling the next generation of large space observatories
The future of space-based UV/optical/IR astronomy requires ever larger telescopes. The highest priority astrophysics targets, including Earth-like exoplanets, first generation stars, and early galaxies, are all extremely faint, which presents an ongo.....»»
The Great Observatory for Long Wavelengths (GO-LoW) proposal
Humankind has never before seen the low frequency radio sky. It is hidden from ground-based telescopes by the Earth's ionosphere and challenging to access from space with traditional missions because the long wavelengths involved (meter- to kilometer.....»»
Two small NASA satellites will measure soil moisture, volcanic gases
Two NASA pathfinding missions were recently deployed into low-Earth orbit, where they are demonstrating novel technologies for observing atmospheric gases, measuring freshwater, and even detecting signs of potential volcanic eruptions......»»
X-ray satellite XMM-Newton sees "space clover" in a new light
Astronomers have discovered enormous circular radio features of unknown origin around some galaxies. Now, new observations of one dubbed the Cloverleaf suggest it was created by clashing groups of galaxies......»»
Weak magnetic field may have supported diversification of life on Earth
An unusual reduction in the strength of Earth's magnetic field between 591 and 565 million years ago coincided with a significant increase in the oxygen levels in the atmosphere and oceans, according to a paper published in Communications Earth & Env.....»»
NASA says Artemis II report by its inspector general is unhelpful and redundant

TOI-837 b is a young Saturn-sized exoplanet with a massive core, observations find
European astronomers have performed photometric and spectroscopic observations of a distant giant exoplanet known as TOI-837 b. As a result, they found that TOI-837 b is a young Saturn-sized planet containing a massive core, which challenges current.....»»
New computer algorithm supercharges climate models and could lead to better predictions of future climate change
Earth System Models—complex computer models that describe Earth processes and how they interact—are critical for predicting future climate change. By simulating the response of our land, oceans and atmosphere to manmade greenhouse gas emissions,.....»»
Start today: Save with Dell and shape a more sustainable future for us all
The Dell sustainability mission for Earth Day 2024 means you can save while also remaining eco-conscious, something we desperately need in today's world......»»
Launch date set for NASA"s PREFIRE mission to study polar energy loss
NASA and Rocket Lab are targeting no earlier than Wednesday, May 22, 2024, for the first of two launches of the agency's PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission to study heat loss to space in Earth's polar regions......»»
An AI model to reduce uncertainty in evapotranspiration prediction
When scientists look at the Earth's available water for ecosystem services, they don't just look at precipitation. They must also account for water moving from the ground to the atmosphere, a process known as evapotranspiration (ET)......»»
Researchers explore an old galactic open cluster
Using data from ESA's Gaia satellite, astronomers from Turkey and India have investigated NGC 188—an old open cluster in the Milky Way. Results of the study, published April 19 on the pre-print server arXiv, deliver important insights into the para.....»»
How the plant world shapes the climate cycle
In order to understand the Earth's resilience, researchers at ETH Zurich are modeling climate changes from times long past. And they show that plants are not simply victims of circumstances, but have helped to shape climate conditions on Earth......»»
Astronomers" simulations support dark matter theory
Computer simulations by astronomers support the idea that dark matter—matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe—exists, according to the resear.....»»
NASA lays out how SpaceX will refuel Starships in low-Earth orbit
