Go behind the scenes with Björn Ottosson, the Swedish engineer who created Oklab color space, and discover how he developed a simple yet effective model with good hue uniformity while also handling lightness and saturation well — and is “okay” to use. Oklab is a new perceptual color space supported in all major browsers created […]

A comet that has not been seen from Earth since Neanderthals were alive and kicking has reappeared in the sky, with astronomers saying it might be visible to the naked eye. Comet C/2023 A3 (Tsuchinshan–Atlas) was discovered by astronomers early last year, and is thought to orbit the sun about every 80,000 years on a […]
Supermassive black holes are, as you might expect, rather large – millions and sometimes billions of times as massive as the sun. They lurk at the centre of all large galaxies, including our Milky Way, shaping the growth of these cosmic structures. And yet we can say precious little for certain about how they form […]

As the autumn proceeds, the constellation will rise earlier and earlier. Pisces […]
On 4 September, an asteroid was spotted curving towards Earth. Astronomers quickly established that it would impact the planet in 10 hours’ time. The Philippines island of Luzon was in the line of fire, and there was nothing they could do about it but watch. Sure enough, at 16.39 UTC (17.39 in the UK), just […]
