Scientists found evidence of a distant planet’s moon system forming

On 2 December 1995 the ESA/NASA Solar and Heliospheric Observatory (SOHO) blasted into space – on what was supposed to be a two-year mission. 

From its outpost 1.5 million km away from Earth in the direction of the Sun, SOHO enjoys uninterrupted views of our star. It has provided a nearly continuous record of our Sun’s activity for close to three 11-year-long solar cycles. 

We knew from prior analyses that a distant asteroid sampled in 2020 carried all but one of the molecules needed to kick-start life, and researchers have just found the missing ingredient: sugar

Russia's only launch site capable of sending humans to orbit has suffered serious damage that may take two years to fix. Will NASA keep supporting the ISS without Russian involvement, or is this the end for the space station?

Tumour growth is reduced by exercise due to a shift in the body’s metabolism that means muscle cells outcompete cancer cells in the race to get sugar to grow

The complex molecules required for life on Earth might never have formed if it wasn’t for cosmic dust.

The company behind TikTok is rolling out a smartphone AI assistant that behaves less like an app and more like a secretary

There is a period in the Universe known as the cosmic dark ages. It lies between the recombination of the first atoms and the ignition of the first stars, when the Universe was thought to be cold and dark. Now astronomers have looked at the faint glow of atomic hydrogen to find that while the Universe was dark, it wasn't quite as cold as we thought.

NASA's James Webb Space Telescope took a look at the Sagittarius B2 molecular cloud, the most massive, and active star-forming region in our galaxy, located only a few hundred light years from our central supermassive black hole.

We have long struggled to determine how the first living organisms on Earth came together. Now, surprising evidence hints that poorly understood prions may have been the vital missing ingredient
