The remains of a tortoise and its egg have been unearthed by archaeologists in Pompeii, the Roman city buried in a volcanic eruption in 79 AD. The animal was found hidden under the clay floor of a storehouse and probably died before Vesuvius erupted.

Climate tech firm to launch scaled-up plant-sucking CO2 from air

Construction is due to begin on Wednesday on what could become the world's biggest plant to capture carbon dioxide from the air and deposit it underground, the company behind the nascent green technology said. Swiss start-up Climeworks AG said its second large-scale direct air capture (DAC) plant will be built in Iceland in 18-24 months, and have the capacity to suck 36,000 tonnes of CO2 per year from the air.

Meet the 'zombie star' that survived a supernova blast

Chinese spacecraft acquires images of entire planet of Mars

An uncrewed Chinese spacecraft has acquired imagery data covering all of Mars, including visuals of its south pole, after circling the planet more than 1,300 times since early last year, state media reported on Wednesday. China's Tianwen-1 successfully reached the Red Planet in February 2021 on the country's inaugural mission there. A robotic rover has since been deployed on the surface as an orbiter surveyed the planet from space.
