With satellite numbers skyrocketing over the next few years, the time to grasp the implications is now

Proxima Centauri's flaring activity has been well known to astronomers using visible wavelengths, but new observations with the Atacama Large Millimeter/submillimeter Array (ALMA) highlight the star's extreme activity at radio and millimeter wavelengths.

Engineers at NASA's Jet Propulsion Laboratory have conserved energy supplies on the record-setting Voyager 1 & 2 deep space probes nearly 50 years after their missions launched to extend them further.

Nearly all modern power generation still relies on turbines—technology dating back to 1884. In a world of AI and electric vehicles, is this really the best we can do? Join me as I explore the physics behind turbines, their role in the grid, and what the future of energy might hold

The ocean has a major influence on weather and climate. Scientists estimate it has absorbed more than 90% of the heat and 25% of the excess carbon released into the atmosphere by human activities.

In a major step for the international Deep Underground Neutrino Experiment (DUNE), scientists have detected the first neutrinos using a DUNE prototype particle detector at the U.S. Department of Energy's Fermi National Accelerator Laboratory (Fermilab).

Scientists attempting to discover the process by which the moon formed have new clues thanks to graphene discovered in lunar samples returned by China's...

NASA Johnson Space Center: ORDEM represents the state of the art in orbital debris models intended for engineering analysis. It is a data-driven model,

The Landolt Space Mission will orbit an artificial star to aid with telescope calibration. Better data will lead to new insights on a range of cosmic mysteries. The post Artificial star to help probe a range of cosmic mysteries first appeared on EarthSky.

Cold, dense clouds in the interstellar medium of our Milky Way Galaxy are around four-five orders of magnitude denser than their diffuse counterparts.

Scientists have predicted that by 2040, almost 50 percent of the world's electric power will be used in computing. What's more, this projection was made before the sudden explosion of generative AI. The amount of computing resources used to train the largest AI models has been doubling roughly every 6 months for more than the past decade. At this rate, by 2030 training a single artificial-intelligence model would…

Every now and then, tiny particles of antimatter strike Earth from cosmic parts unknown. A new balloon-borne experiment launching this spring may at last find their source

MethaneSAT will orbit the planet 15 times a day to capture unprecedented amounts of data on methane emissions from human and natural sources

Of the approximately 5,500 exoplanets discovered to date, many have been found to orbit very close to their parent stars. These close-in planets provide a unique opportunity to observe in detail the phenomena critical to the development and evolution of our own solar system, including atmospheric mass loss and interactions with the host star. NASA's […]

Every so often, Earth's magnetic poles completely flip. What causes this to happen? And how do these reversals affect life on Earth?

We have been treated to some amazing aurora displays over recent months.

NOAA's Space Weather Prediction Center has released a "revised prediction" for the current solar cycle, which states that the upcoming solar maximum will arrive sooner and be more explosive than they initially forecast — as Live Science previously reported.

A new EU mission has sent some suitably space-age tech into the cosmos. On a Vega rocket that launched from the European spaceport in French Guyana on Monday, the union sent six satellites ...

With so many early galaxies of unexpectedly large brightnesses, JWST surprised us all. Here's how scientists made sense of what we see.
