The inside of Mars isn’t smooth and uniform like familiar textbook illustrations. Instead, new research reveals it’s chunky - more like a Rocky Road brownie than a neat slice of Millionaire’s Shortbread.
Clues about how worlds like Earth may have formed have been found buried at the heart of a spectacular 'cosmic butterfly'. With the help of the James Webb Space Telescope, researchers say they have made a big leap forward in our understanding of how the raw material of rocky planets comes together. This cosmic dust – tiny particles of minerals and organic material which include ingredients linked to the origins of life – was studied at the core of the Butterfly Nebula, NGC 6302, which is located about 3,400 light-years away in the constellation Scorpius. From the dense, dusty torus that surrounds the star hidden at the centre of the nebula to its outflowing jets, the Webb observations reveal many new discoveries that paint a never-before-seen portrait of a dynamic and structured planetary nebula. They have been published today in Monthly Notices of the Royal Astronomical Society.
Using a cutting-edge adaptive optics system developed at the University of Arizona's Steward Observatory, a growing planet outside our solar system has been discovered to inhabit a gap in a disk of dust and gas. The images provide a glimpse of what our solar system likely looked like during its infancy.
A newly developed highly sensitive detector is making it possible for the first time in decades to expand the search for dark matter, the elusive particles believed to make up roughly 85% of the universe but that have never been directly observed in a lab. The advance could either generate the first direct evidence of dark matter or rule out broad classes of theories that have yet to be tested.
