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.....»»
Team discovers three new magnetic and helium-enriched hot subdwarf stars
An international team of astronomers reports the discovery of three new helium-enriched hot subdwarf stars with strong magnetic fields. The finding, made with the Southern African Large Telescope (SALT), is detailed in a research paper published Oct......»»
The transition to a circular bioeconomy requires getting prices right, study says
Conventional food and agricultural production systems employ a linear "take, make, waste" approach: taking natural resources from the Earth to make food and fuel, generating waste that contaminates the soil and water, and emitting harmful pollutants......»»
How accessible is titanium on the moon?
Mining the moon to extract its resources is a critical step on humanity's path into the solar system. One of the most common resources on the moon is considered relatively valuable here on Earth—titanium......»»
Injured comb jellies can fuse into a single organism
Ctenophores merge with neighbors at wound sites, making animals with duplicate parts. Comb jellies, technically known as ctenophores, are one of the weirdest creatures on Earth. T.....»»
Anti-glitches detected in gamma-ray pulsar PSR J1522-5735
By analyzing the data from NASA's Fermi Gamma-ray Space Telescope, Russian astronomers have detected anti-glitches in a gamma-ray pulsar designated PSR J1522-5735. The discovery, published September 28 on the pre-print server arXiv, makes PSR J1522-5.....»»
Control the path and power of hurricanes like Milton? Forget it, scientists say
Hurricanes are humanity's reminder of the uncontrollable, chaotic power of Earth's weather......»»
The other greenhouse gases warming the planet
While carbon dioxide, or CO2, is the best known greenhouse gas, several others, including methane and nitrous oxide, are also driving global warming and altering the Earth's climate......»»
Research suggests Earth"s oldest continental crust is disintegrating
Earth's continental configurations have changed dramatically over its billions of years' history, transforming not only their positions across the planet, but also their topography as expansion and contraction of the crust made a mark on the landscap.....»»
SpaceX’s Hera launch offers sublime view of Earth
A SpaceX rocket that launched a planetary defense mission on Monday captured a breathtaking view of Earth shortly after reaching orbit......»»
New study eases concerns over possible "doomsday" asteroid swarm
Astronomers have good news about potentially hazardous asteroids lurking near our planet: There aren't as many as we thought......»»
Astronomers investigate the nature of a fast-spinning intermediate polar
Using various X-ray space observatories, astronomers from Columbia University in New York and elsewhere have investigated CTCV J2056–3014—an intermediate polar containing one of the fastest-spinning white dwarfs. Results of the study, published S.....»»
Limestone and iron reveal puzzling extreme rain in Western Australia 100,000 years ago
Almost one-sixth of Earth's land surface is covered in otherworldly landscapes with a name that may also be unfamiliar: karst. These landscapes are like natural sculpture parks, with dramatic terrain dotted with caves and towers of bedrock slowly scu.....»»
Large radio bubble detected in galaxy NGC 4217
An international team of astronomers has performed radio observations of a star-forming galaxy known as NGC 4217. The observational campaign detected a large radio bubble in the galaxy's halo. The finding was reported in a paper published September 2.....»»
New Kuiper Belt objects lurk farther away than we ever thought
Earth's Kuiper Belt appears to be substantially larger than we thought. In the outer reaches of the Solar System, beyond the ice giant Neptune, lies a ring of comets and dwarf pla.....»»
Capturing finer-scale topographic differences improves Earth system model capability to reproduce observations
Earth system models (ESMs), used in climate simulations and projections, typically use grids of 50–200 km resolution. These are considered relatively coarse with limited ability to resolve land surface variability......»»
The sun unleashes its strongest flare this cycle
Yesterday the sun released a huge solar flare, and it's heading toward Earth. It's nothing to worry about since it's nowhere near as large as the Carrington Event of 1859, but it is large enough to give us some amazing aurora......»»
So You Can 3D Print a Steak Now—but Why on Earth Would You?
WIRED tried 3D-printed steaks that you can’t buy anywhere yet. But reducing food to a technological problem leaves a bitter taste, and delivers all the joy of licking a catering catalog......»»
Earth Defense Force 6 just removed its controversial requirement
Sci-fi shooter Earth Defense Force 6 just removed an account requirement on Steam that led players to review-bomb it at launch......»»
X-rays advance understanding of Earth"s core-mantle boundary and super-Earth magma oceans
Researchers at the Department of Energy's SLAC National Accelerator Laboratory have revealed new details about Earth's core-mantle boundary and similar regions found in exoplanets......»»
NASA is working on a plan to replace its space station, but time is running out
"Initially, Congress almost treated the program as a joke." The next year is crucial for the future of NASA and its plans to extend human activity in low-Earth orbit. For the firs.....»»
