Spider silk is an extremely strong material, a strand thick as a pencil, enough to stop a jet plane in flight!
Yet the frailest of houses is that of the the spider (Ankaboot)!
An amazing video by Russian space agency Roscosmos shows the horizon with some celestial bodies like black holes very much closer to earth than they really are – and it’s wonderful and eerie.
The video is not a scientific simulation – a black hole or a supernova exploding star couldn’t exist in such proximity of the Earth, or rather vice versa – but a splendid illustration of what celestial bodies look like, as documented by telescopes like Hubble.
Among the celestial bodies in the video, are, for instance, the Whirlpool Galaxy, which is 30 million light years from Earth, and the Andromeda Galaxy, about 2.5 million light years from Earth.
The footage followed another video, showing how our horizon would look like if other Solar System planets were at the distance of the Moon.
A local photographer captures the formation of the saucer-shaped puffs amid a skyline he described as "unbelievable".
Residents of Cape Town may have thought they were seeing UFOs in the sky - but instead they were being treated to a special cloud formation.
The lenticular clouds appeared over the South African city late on Sunday afternoon and photographer Kyle Mijlof was among those capturing the scene, which he described as "unbelievable".
Mr Mijlof told Sky News the clouds started forming over Table Mountain - about five miles from the city - at around 3pm and his picture was taken three hours later as the formation peaked.
He added: "Honestly, the whole skyline that day was unbelievable and a bit of an eerie stillness in the air.
"I was on my scooter at the time, driving along Signal Hill back home to Camps Bay, I stopped to get this quick shot - I still had my helmet on."
Mr Mijlof said he has seen similar clouds during his travels elsewhere in the world but not in Cape Town.
Sky News meteorologist Chris England said: "They are formed at the top of waves in the atmosphere caused by air going over mountains and are quite common, although more often as long bands of simple arcs."
He said the shapes are formed by either variations in humidity within the air or the originating hills being "fairly isolated peaks".
Picturesque Cape Town is framed by peaks, including Table Mountain, which is around 3,500ft high.
England added: "Lenticular clouds don't really signify anything in particular about the weather, apart from fact that the atmosphere is stable at the time and so not much convection likely - and that can change quite rapidly."
Lenticular clouds, which come from a Latin word meaning "lens-like", can form in many places around the world and have been blamed for a number of previous "UFO sightings".
This cannot be undone and I am sure it will be greatly appreciated.
