A harmonia entre espĂ©cies đ
O nosso planeta Ă© um pontinho solitĂĄrio na grande escuridĂŁo cĂłsmica circundante. Em nossa obscuridade, no meio de toda essa imensidĂŁo, nĂŁo hĂĄ nenhum indĂcio de que, de algum outro mundo, virĂĄ socorro que nos salve de nĂłs mesmos

â Greyâs Anatomy (3x10).
My dad Russell Kightleyâs illustration of an animal cell (which includes humans too) has recently gone viral on the internet. Iâve always been very proud of his work. I used to take in big laminated posters (biocam.com) of his scientific illustrations into class to showcase the intricacies of various cells, including plant and animal, as well as different viruses, organisms etc. He also drew a Coronavirus life cycle in 2003 when SARS broke out; many people donât realise but SARS was also Coronavirus, âCoronaâ is Latin for âcrownâ and refers to the crown like spikes around a particular virus.
From start; Animal cell, plant cell, coronavirus lifecycle, parameciums, amoeba.

A Vortex Aurora over Iceland : No, the car was not in danger of being vacuumed into space by the big sky vortex. For one reason, the vortex was really an aurora, and since auroras are created by particles striking the Earth from space, they do not create a vacuum. This rapidly developing auroral display was caused by a Coronal Mass Ejection from the Sun that passed by the Earth closely enough to cause a ripple in Earthâs magnetosphere. The upper red parts of the aurora occur over 250 kilometers high with its red glow created by atmospheric atomic oxygen directly energized by incoming particles. The lower green parts of the aurora occur over 100 kilometers high with its green glow created by atmospheric atomic oxygen energized indirectly by collisions with first-energized molecular nitrogen. Below 100 kilometers, there is little atomic oxygen, which is why auroras end abruptly. The concentric cylinders depict a dramatic auroral corona as seen from the side. The featured image was created from a single 3-second exposure taken in mid-March over Lake Myvatn in Iceland. via NASA
