Thank you, Alice.

NASA’s Perseverance Rover Scientists Find Intriguing Mars Rock The six-wheeled geologist found a fascinating rock that has some indications it may have hosted microbial life billions of years ago, but further research is needed.

This story began with a JPL press release in July 2024, soon after the #Mars rock was discovered. www.jpl.nasa.gov/news/nasas-p...

Today is the publication of the peer-reviewed paper describing what's in it. That @nature.com paper is here www.nature.com/articles/s41...

Hameus Mons from Voyager 1

Haemus Mons is a mountain located near Io’s south pole and, in this image, lies near the terminator in this image from Voyager 1 on March 7, 1979. Its base spans about 200 by 100 kilometers.

We analysed every line of X’s algorithm we could get our hands on.

Here’s what we found.

First Time Crystal Made Of "Exotic" Giant Atoms 1,000 times Larger Than Hydrogen A gas of rubidium atoms in the peculiar Rydberg state can turn into a time crystal.

Over the last decade or so, the concept of time crystals has gone from an intriguing hypothesis to an experimental reality.

Holy shit.

This is 3I/ATLAS—the interstellar comet recently discovered passing through the Solar System.

You're looking at something that didn't start out here.

It came from another star.

And, at about 7 billion years old, it was already ancient when our Sun was born.

AGC is very proud to announce the first published article!

Congratulations to the authors who believed in AGC in order to publish their study: doi.org/10.33063/agc...

This is only the beginning.
Many other researchers already submitted their work to AGC and we hope you will be the next ones!

An image of a nearby star and its vicinity. The star itself has been blocked out and its bright light has been removed. A dashed circle with a star symbol at the centre of the image marks the star’s location. A fuzzy blue disc surrounds the star. An orange spot, near to the star and inside this disc, is identified as a planet orbiting the star. A fainter orange spot far from the centre marks a distant star.

The NASA/ESA/CSA James Webb Space Telescope has found evidence of a cold, Saturn-mass planet around the star TWA 7, seemingly sculpting its disc of debris!

If confirmed, this would be Webb’s first direct image discovery of a planet.

See that orange blob?

That's probably a Saturn-mass planet orbiting its parent star, the light from which has been blocked.

A whole other planet in a system only a few million years old, possibly still undergoing formation and developing its own ring and satellite system.

111 lightyears away.

Wilson’s Promontory or Yiruk Wamoon, 3 hours drive from Melbourne, Australia, is National Park with magnificent peaks, beaches, rainforest, and the world’s southernmost mangroves. A hiking and boating paradise, the promontory and surrounding islands are the exposed portions of a Devonian granite batholith.

This image shows the planetary system HR 8799. The image background is black. At the centre of the image, there is a symbol representing a star labeled HR 8799. This star blocks the light from the host star. There are four exoplanets, which look like fuzzy dots, pictured in the image surrounding the star. Furthest from the star is a fuzzy, faint blue dot, labeled b, at the 10 o’clock position. At the one o’clock position, second furthest from the star is a blueish-white fuzzy dot labeled c. Just below that is an orange dot labeled e. At the four o’clock position, still nearby the star, is another fuzzy white dot labeled d.

The NASA/ESA/CSA #Webb Space Telescope has captured direct images of gas giant #exoplanets in a system 130 light-years away, and found evidence that they formed like Jupiter and Saturn 🪐

BREAKING PLANET NEWS 🪐

Rather hilariously, Saturn just got up to 128 new moons (thanks to some careful telescopic observations), bringing its total to…274? That’s just an absurd number of moons.

(Not the MPC bulletin I was expecting today…!)

A Super Speedy Star May Be Streaking Through Our Galaxy - Eos Astronomers suggest the star is towing along an exoplanet. The system could be traveling fast enough to escape the Milky Way.

Warp speed, star style.

The north pole of Saturn with the polar vortex and surrounding cyclones shown in red is surrounded by the faint blue of the gas giant's aurora.

Man Whose Blood Saved 2.4 Million Babies Dies Aged 88 For his impressive feat, he was dubbed "the man with the golden arm".

NASA’s Webb Rings in Holidays With Ringed Planet Uranus - NASA NASA’s James Webb Space Telescope recently trained its sights on unusual and enigmatic Uranus, an ice giant that spins on its side. Webb captured this dynamic

But also captured are 14 of the planet’s 27 moons: Oberon, Titania, Umbriel, Juliet, Perdita, Rosalind, Puck, Belinda, Desdemona, Cressida, Ariel, Miranda, Bianca, and Portia. Except for the few stars with diffraction spikes, everything else is a galaxy!
