New device can scan your face in 3D from hundreds of metres away

A lidar scanner has a resolution so high it can image ridges and indentations of only 1 millimetre on objects hundreds of metres away – and capture objects as distant as 1 kilometre

Asteroid 2024 YR4 may hit Earth in 2032 – how worried should we be?

Analysis

T64HY9 Guangzhou, China's Guangdong Province. 29th Apr, 2019. Koalas rest on a tree at the Chimelong Safari Park in Guangzhou, south China's Guangdong Province, April 29, 2019. A group of six koalas from Australia were introduced in the Guangzhou Chimelong Safari Park in 2006. After 13 years of introducing and breeding, the number of koalas in the park has reached 60 now.

The Sun viewed on 29 January 2025 in the extreme ultraviolet range by NASA's Solar Dynamics Observatory (SDO) spacecraft. A vast 500,000 mile-wide coronal hole has opened in the sun's atmosphere. The area measures over 62 times the diameter of Earth and is now shooting high-speed solar wind toward Earth. When such solar activity is directed at Earth, the resulting geomagnetic storms can potentially disrupt satellite operations, power grids, navigation systems, and radio communications. There may also be spectacular displays of aurora caused as the Earth's magnetosphere is disturbed by the solar wind. According to spaceweather.com, this wind is estimated to hit Earth by Friday (31 Jan), resulting in G1 geomagnetic storm conditions.
