Hundreds of new moons are revealing our solar system's violent history
In the far reaches of the solar system, the planetary neighbourhood seems quiet. Beyond Jupiter, the sun is no longer a blazing disc, but a cold, white lamp. The planets are separated by gulfs of darkness.
Meteorite found in Sahara desert may be 1st evidence of lost solar system world
Meteorite found in Sahara desert may be 1st evidence of lost solar system world "It points to a distinct and separate evolutionary path in planetary formation in the early history of our solar system." A rare meteorite recovered from the Sahara Desert contains the first definitive evidence of a long-lost world that may have rivaled the moon in size and existed just a few million years after the solar system formed 4.5 billion years ago, according to a new study. The meteorite, known as...
One of our planets may be missing, and it could explain why the solar system looks the way it does
June 1, 2026 report One of our planets may be missing, and it could explain why the solar system looks the way it does Paul Arnold Author Sadie Harley Scientific Editor Robert Egan Associate Editor Our solar system has two ice giants, Uranus and Neptune, but there may have been a third. According to a new study published in the journal Icarus, this extra world might have triggered a violent planetary shuffling billions of years ago that could have disrupted some of Jupiter's and Uranus's...

Kaleidoscopic meteorite could be a piece of a 'lost world' from the early solar system — Space photo of the week A rare meteorite found in the Sahara Desert may be evidence of a long-lost "protoplanet" that formed in the early solar system before being destroyed in a colossal collision, a new study suggests Quick facts What it is: NWA 12774, a 16-ounce (454 grams) angrite meteorite Where it was found: The Sahara Desert, Northwest Africa When it was shared: June 1, 2026 Throughout its...
Why do Venus and Jupiter meet up in the sky so often? It's a symptom of a solar system that supports life on Earth
Why do Venus and Jupiter meet up in the sky so often? It's a symptom of a solar system that supports life on Earth "Orbital dynamics allows you to start to think about all those fun, different aspects of what makes our planet habitable, and ask how normal it is to have a habitable planet." Shortly after sunset on June 9, Venus and Jupiter will look very close together, in what is known as a planetary conjunction.
Astronomers measure the mass of a dormant black hole, our solar system's lost protoplanet, and more science stories
Astronomers measure the mass of a dormant black hole, our solar system's lost protoplanet, and more science stories This week's science news. It's been an eventful week in science news. Astronauts on the ISS were briefly ordered to shelter in place after the discovery of an air leak in the transfer tunnel, NASA officially declared its MAVEN space probe dead and scientists announced the creation of a "universal vaccine" designed by AI.

One of Neptune's 16 moons is not like the others, James Webb telescope finds — and it could be key to fully understanding the solar system
Nereid (inset) may be the only moon of Neptune (background) that was around when the planet first formed, a new JWST study hints. (This composite image is not to scale).
Show HN: Gravity – interactive solar-system simulator, from Newton to Einstein
Just for fun and self education, I've built this over a weekend to teach myself why orbits exist, not just show planets going around. Something that was never clearly explain to me in school. It opens with a guided tour that builds the idea up step by step: two bodies and the equal/opposite force, inertia (the Sun is removed and Earth just drifts straight), then "an orbit is falling and continuously missing," cosmic velocities with a little rocket, Voyager 1 & 2's real gravity assists (the...
