Sirius, a double-star system and the brightest object in the night sky, will briefly blink out of existence for parts of Earth on Monday evening. In an event called an occultation – when one object in space blocks the light of another behind it – a small asteroid known as (4388) Jürgenstock will slip in front of the
There’s no two-ways about it, the Universe is an extremely big place! And thanks to the limitations placed upon us by Special Relativity, traveling to even the closest star systems could take millennia. As we addressed in a previous article, the estimated travel time to the nearest star system (Alpha Centauri) could take anywhere
Astronomers have been treated to a truly special look at some of the organic building blocks of the Universe, thanks to a newborn star that’s been spotted around 1,300 light-years away from Earth. That star is V883 Ori – as it grows, the bursting heat is pushing back the star’s ‘snow line’ – that’s the area around
Some of the most spectacular pictures of deep space are of nebulae – gorgeously coloured clouds of dust and gas glowing from within. They look peaceful and serene, but in actuality, they’re scenes of violence. Usually, nebulae are either the lingering ghosts of exploded stars, or stellar nurseries – regions where stars are being
3D printers work by laboriously printing objects layer by layer. For larger objects, that process can take hours or even days. But now scientists at the University of California, Berkeley have found a shortcut: a printer that can fabricate objects in one shot using light – and which could, potentially, revolutionize rapid manufacturing technology.
