Saturday Citations: Moon origins, rat whimsy, microgravity orientation. Plus: Starfish are bodiless heads, it turns out

Good morrow and a cheerful week's end to you. This week, we reported on notable developments in the lack of starfish body development. Physicists used a new method to revisit the planetary collision that likely formed the ...

Plot thickens in the hunt for a ninth planet

A pair of theoretical physicists are reporting that the same observations inspiring the hunt for a ninth planet might instead be evidence within the solar system of a modified law of gravity originally developed to understand ...

Machine learning algorithms can find anomalous needles in cosmic haystacks

The face of astronomy is changing. Though narrow-field point-and-shoot astronomy still matters (JWST anyone?), large wide-field surveys promise to be the powerhouses of discovery in the coming decades, especially with the ...

New Mars gravity analysis improves understanding of possible ancient ocean

The first use of a novel method of analyzing Mars' gravitational force supports the idea that the planet once had an extensive northern ocean.

It's going to take more than early dark energy to resolve the Hubble tension

Our best understanding of the universe is rooted in a cosmological model known as LCDM. The CDM stands for cold dark matter, where most of the matter in the universe isn't stars and planets, but a strange form of matter that ...

A novel method uses gravity data to determine where density anomalies lie inside planetary bodies

Getting to know planets or moons inside out isn't easy. Like Earth and its moon, many celestial bodies are multilayered and can contain anomalous internal features that reflect the complex history of their formation, collisions ...

Earth's core, replete with oceans and cyclones, is being demystified

At the center of Earth is a vast ball of metal, the planet's core. While unreachable without the help of Jules Verne, it can be studied and plays a vital role for the world.

Smoking-gun evidence for modified gravity at low acceleration from Gaia observations of wide binary stars

A new study reports conclusive evidence for the breakdown of standard gravity in the low acceleration limit from a verifiable analysis of the orbital motions of long-period, widely separated, binary stars, usually referred ...

Volunteers invited to play 'spot the difference' to help scientists identify cosmic explosions

Members of the public are invited to take part in a brand new citizen science project to identify cosmic explosions in real-time.

AI is helping astronomers make new discoveries and learn about the universe faster than ever before

The famous first image of a black hole just got two times sharper. A research team used artificial intelligence to dramatically improve upon its first image from 2019, which now shows the black hole at the center of the M87 ...
