This is a tree that was struck by lightning and revealed its vascular system !! 🌳 Nature is so complicated. The vascular system of a tree transports water and minerals from the roots to the leaves ! As vascular plants, trees are organized into three major organs: the roots, the stems, and the leaves. The leaves are the principal photosynthetic organs of most higher vascular plants. They are attached by a continuous vascular system to the rest of the plant so that free exchange of nutrients, water, and end products of photosynthesis (oxygen and carbohydrates in particular) can be carried to its various parts. The stem is divided into nodes (points where leaves are or were attached) and internodes (the length of the stem between nodes). The leaves and stem together are called the shoot. Shoots can be separated into long shoots and short shoots on the basis of the distance between buds (internode length). The stem provides support, water and food conduction, and storage. Roots provide st...

A large stony asteroid safely pass Earth today January 18, 2022. Its estimated size is around 3,280 feet (about 1 km or .6 of a mile), around 2 1/2 times the height of the Empire State Building. As you can see from this asteroid’s label – (7482) 1994 PC1 – we’ve known about it since 1994. It is classified as a Potentially Hazardous Asteroid due to its size and relatively close flybys of our planet. An asteroid of this size strikes Earth approximately every 600,000 years. But we have nothing to fear from 1994 PC1 at its 2022 close approach. And … a plus … amateur astronomers with backyard telescopes might catch a glimpse of it as it sweeps past. 1994 PC1 orbits the Sun at a distance of 0.9–1.8 AU once every 1 years and 7 months (572 days). Its orbit has an eccentricity of 0.33 and an inclination of 33° with respect to the ecliptic. On 17 January 1933, it passed 811,350 km (504,150 mi) from the Moon and then about a hour later made its closest known approach to Earth of 1,125,400 km (699...
