'Mini-Neptune' exoplanets may have smoggy atmospheres similar to diesel exhaust Lisa Lock Scientific Editor Robert Egan Associate Editor The astronauts circling Earth on the Artemis mission sent back beautiful clear photos of the continents, clouds, and oceans. But we might be the exception.
2 giant 'super Earths' once orbited near Uranus and Neptune, messed up a bunch of moons, then vanished, new study hints
2 giant 'super Earths' once orbited near Uranus and Neptune, messed up a bunch of moons, then vanished, new study hints Our solar system may have hosted up to six giant planets in its first hundred million years, a new study suggests. The findings paint a more crowded picture of the early outer solar system than previously thought. Something doesn’t quite add up about the orbits of our solar system’s eight planets and their hundreds of moons, a new study hints.
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).
Most exoplanets might be 'soot factories,' scientists say: 'Like you have a natural diesel engine'
Most exoplanets might be 'soot factories,' scientists say: 'Like you have a natural diesel engine' A chemical engineer noticed that the spectra of the hazy atmosphere of mini-Neptune planets looked like the soot produced by combustion engines. Vast clouds of soot that form in the pressure cooker of mysterious mini-Neptune exoplanets may hold the truth about these worlds' origins. "It's like you have a natural diesel engine in the deep atmosphere of a planet," lead author of a study about...

The Moons of Uranus May Hold the Key to Finding Missing Planets
We have an idea of what the solar system's past was like: It was violent and chaotic. However, we are still studying how violent it was. Current models suggest that at some point after their formation, the giant planets went through a phase of such extreme instability that one or even two bodies the size of Uranus or Neptune were ejected into interstellar space.
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...
New study has shone a new light on searching for habitable worlds
New study has shone a new light on searching for habitable worlds Sadie Harley Scientific Editor Andrew Zinin Lead Editor When astronomers discovered the first planet outside our solar system, it was orbiting a pulsar, one of the most extreme, radiation-blasted environments imaginable. Not exactly the kind of place you'd expect to find a planet, let alone a representative one. The first confirmed exoplanet was an oddity, a product of the fact that pulsar timing is extraordinarily sensitive,...
Can solar sails really send humans out into interstellar space?
Can solar sails really send humans out into interstellar space? "I think these are not far-out type of ideas; they are not really futuristic ideas that we are talking about." If humankind ever travels to distant stars, we might sail there — and it might be sooner than you think.
This new private island retreat in France is taking wellness to the next level
This sea-facing escape harmonises holistic wellbeing with Mediterranean dining, which includes personalised consultations, tailored treatments across five wellness programmes and three choices of residence – all in one retreat.
