Physicists Just Showed How to Overcome a Huge Obstacle For Fusion Generator Efficiency
Energy generated from nuclear fusion holds plenty of potential as a clean and almost limitless source of power, but many obstacles need to be overcome before it's a practical reality – and scientists may have just clambered over another one.

Hubble Just Took an Astonishingly Detailed Image of Saturn
The Hubble space telescope has spent the past 30 years orbiting 547 km (340 miles) above Earth. The ageing satellite has had a couple of hiccups in the last few years, but it's not done taking incredible photos of our cosmic backyard yet.

Mesmerising Animation Reveals Our Entire Solar System Doesn't Exactly Orbit The Sun
It's common knowledge that the Sun is the centre of the Solar System. Around it, the planets orbit – along with a thick belt of asteroids, some meteor fields, and a handful of far-travelling comets.

AI Analysed Over 11,000 Couples' Relationships. This Is What It Found

For the first time, scientists have observed that 'megaripples' on Mars – huge sand waves seen on the Martian surface – are moving structures, and not ancient relics stuck in place since the Red Planet's distant past.
Sand dunes and ripples are typical features of deserts on Earth and Mars. Megaripples are distinguished from smaller ripples by the coarser sand grains that gather at their crests and their larger size: the ripples range from 30 centimeters (1 foot) to tens of meters across.
This video shows movement of Martian megaripples in several locations on the Red Planet. You can see the slight change in the ripples’ position over the course of seven to ten years.

Modified gravity theories have never been able to describe the universe’s first light. A new formulation does.
A view of the center of the Milky Way galaxy. Theories of modified gravity have had a hard time describing the universe from relatively small scales like this all the way up to the scale of the universe as a whole.
For decades, a band of rebel theorists has waged war with one of cosmology’s core concepts — the idea that an invisible, intangible form of matter forms the universe’s primary structure. This dark matter, which seems to outweigh the stuff we’re made of 5-to-1, accounts for a host of observations: the tight cohesion of galaxies and packs of galaxies, the way light from faraway galaxies will bend on its way to terrestrial telescopes, and the mottled structure of the early universe, to name a few.
