Caterpillars appear to have lots of legs but only 6 are true legs. The other legs are false legs (called prolegs) that help the caterpillar to climb and move around plant surfaces. Prolegs may be as many as 10 and are usually located on a caterpillar’s abdomen.

About -
lightning tends to hit tall objects, trees are likely targets. They're especially prone to lightning strikes because electricity seeks the path of least resistance, and the sap and moisture inside a tree make it a better conductor than the surrounding air.

Who knows what part of the earth we are looking at? Can you name some of these cities? 🌍 👀

The green flare that you see are the northern lights. The Northern Lights are actually the result of collisions between gaseous particles in the Earth's atmosphere with charged particles released from the sun's atmosphere. Variations in colour are due to the type of gas particles that are colliding.

Follow us for more - .lscience.. 'Ghost apples'. These really look as if they are made of crystal! And no, you cannot eat them, else you might end up getting a brain freeze 😄.

These fragile, apple-shaped ice shells are a rare phenomenon indeed and they were formed after an ice storm had hit Michigan. Andrew Sistema, a farmer from Kent County in Michigan stumbled upon these particularly shaped orbs while pruning his trees in his orchard, and which he has since dubbed 'ghost apples'.
For these ghost apples to form, very specific weather conditions are required. It must be cold enough for rain to freeze perfectly around the skin of the fruit and stop the ice from melting; but also warm enough to decay the apples into almost an applesauce-like consistency. When the trees are shaken, the rotten apple mush seeps out from the bottom of the frozen shells, resulting in a detailed, crystal-like impression of an apple. This is only possible because apples have a lower freezing point than water, due to their higher sugar and acid content.

Like a gift to the cosmos, the James Webb Space Telescope was launched atop an Arianespace Ariane 5 rocket from Europe’s Spaceport in French Guiana on Dec. 25, 2021, at 7:20 a.m. EST (12:20 UTC). The largest, most complex, and most powerful space telescope ever built, Webb will begin a nearly two-week process of unfolding its instruments, mirrors, and tennis-court-sized sunshield as it cruises through deep space to its destination 1 million miles (1.5 million kilometers) from Earth. For nearly 29 days, it will journey to Lagrange point 2, a gravitational well that lets the telescope stay in line with Earth as it moves around the Sun.

A joint effort with the , the , and , Webb will study infrared light with much greater clarity than ever before and help reveal cosmic history – from within our solar system to the most distant observable galaxies in the early universe, to everything in between. But perhaps what’s most interesting is that we don’t yet know what Webb will discover. Will we have more questions? Time will tell. We'll be ready.

Bioluminescence algae 🌌 Which one is your favorite?(1~7)

Thus phenomenon is called Bioluminescence algae. Bioluminescent algae are a group of tiny marine organisms that can produce an ethereal glow in the dark. While the phenomenon may occur in any region or any sea depth, some of the most stunning instances happen on the surface when the algae come close to shore, sparkling with the movement of the waves or through the jostling of boats.

Choose your planet‼️ 🟠 🪐 ⚪️ 🔵

: This photo puts the giant planet’s tumultuous atmosphere on full display. The planet’s equatorial zone is now a deep orange hue, which researchers are calling unusual. Just above the equator, researchers note the appearance of several new storms, nicknamed “barges.” These elongated, deeply structured red cells can be defined as cyclonic vortices, which vary in appearance. Researchers also note that a feature dubbed “Red Spot Jr.”, below the Great Red Spot where Hubble just discovered winds are speeding up, is still a darker beige colour, and is joined by several additional white, cyclonic storms to the south.

: This shot shows rapid and extreme colour changes in the bands in the planet’s northern hemisphere, where it is now early autumn. The bands have varied throughout Hubble observations in both 2019 and 2020. Hubble’s Saturn image catches the planet following the southern hemisphere’s winter, evident in the lingering blue-ish hue of the south pole.

: This view puts the planet’s bright northern polar hood in the spotlight. It’s springtime in the northern hemisphere and the increase in ultraviolet radiation from the Sun seems to be causing the polar region to brighten. Researchers aren’t sure why. It could be a change in the opacity of atmospheric methane haze, or some variation in the aerosol particles. Curiously, even as the atmospheric hood gets brighter, the sharp southernmost boundary remains at the same latitude. This has been constant over the past several years of Hubble observations of the planet. Perhaps some sort of jetstream is setting up a barrier at that latitude of 43º.

: The dark spot, which was recently found to have reversed course from moving towards the equator, is still visible in this image, along with a darkened northern hemisphere. There is also a notable dark, elongated circle encompassing Neptune’s south pole. The blue colour of both Neptune and Uranus is a result of the absorption of red light by the planets’ methane-rich atmospheres.

On this day, 7th of november, we remember 2 of greatest physicist of all time in their birth anniversary. Madame Curie and CV Raman. Madame Curie is reknowned for her works on radioactivity and discovery of element radium. CV Raman is reknowned for his work on scattering effect of light which we call Raman Effect. Both of the physicists were honoured by the prestigious Nobel Prize on Physics. Madame Curie won Nobel prize on Chemistry too.

Becoming double-awarded laureate Marie Skłodowska Curie.

Born as Maria Skłodowska in 1867 in Warsaw, the girl in the left image would grow up to become one of the most loved and respected scientists of our time. Her insatiable curiosity made her an icon in the world of modern science.

She discovered polonium and radium, championed the use of radiation in medicine and fundamentally changed our understanding of radioactivity. Her scientific contributions led to two Nobel Prizes (physics 1903 and chemistry 1911) and she is still today the only person that has been awarded two Nobel Prize in two scientific categories.

A Russian unmanned spacecraft, Venera 4, for the first time ever, entered the atmosphere of Venus on this day, i.e., October 18, in 1967. The space probe was the first to transmit data from the atmosphere of another planet. Venera 4 was launched from a Tyazheliy Sputnik on June 12, 1967, and after a mid-course correction, the probe was released from the bus and entered the nightside Venusian atmosphere on October 18, 1967.

The Murchison meteorite is a meteorite that fell in Australia in 1969 near Murchison, Victoria. It belongs to a group of meteorites rich in organic compounds. Due to its mass (over 100 kg or 220 lb) and the fact that it was an observed fall, the Murchison meteorite is one of the most studied of all meteorites
One of the oldest rocks in existence, the Murchison Meteorite. It's 4,600,000,000 years old, and likely existed before the Earth itself had completely formed. (Basilicofresco)......
In January 2020, cosmochemists reported that the oldest material found on Earth to date are the silicon carbide particles from the Murchison meteorite, which have been determined to be 7 billion years old, about 2.5 billion years older than the 4.54-billion-year age of the Earth and the Solar System. The published study noted that "dust lifetime estimates mainly rely on sophisticated theoretical models. These models, however, focus on the more common small dust grains and are based on assumptions with large uncertainties.

What are the "Waning" & the "Waxing" Moon? 🌙 🌕
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
The moon is called a waning moon when it is in the phase in which its visible surface area is getting smaller. A waning moon occurs between a full moon (when the visible surface is fully round and lit up) and a new moon (when the surface that faces Earth is completely covered in shadow).
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
Waxing Moon means the Moon's illumination is growing, and 'Crescent' means less than half of the Moon is illuminated. This moon phase signifies intention.

Did you know.. The International Flat Earth Research Society, which was set up in 1956 by Samuel Shenton, a sign writer living in Dover, UK, was regarded by many people as merely a symbol of British eccentricity amusing and of little con sequence. But in the early 2000s, with the Internet now a well-established vehicle for off-beat views, the idea began to bubble up again, mostly in the US. Discussions sprouted in online forums, the Flat Earth Society was relaunched in October 2009 and the annual flat-Earth conference began in earnest' physicsworld.com

In 1610, the year after Galileo Galilei turned a telescope to the sky, he became the first person to observe Saturn's rings, though he could not see them well enough to discern their true nature. In 1655, Christiaan Huygens was the first person to describe them as a disk surrounding Saturn.
