What are two amazing medical discoveries of 2022?
Earliest surgery
After investigating the skeleton of a person who lived on the Indonesian island of Borneo about 31,000 years ago researchers found out that the first known surgical operation was a leg amputation ⬆️. Healed bone where the lower left leg had been removed suggests the individual survived for several years after the procedure. The discovery pushes surgery’s origin back by some 20,000 years.
Resurrecting dying organs
Yale scientists succeeded in reviving cells in the hearts, liver, kidneys, and brains of pigs that had been lying dead in a lab for an hour. The researchers used a device much like a heart-lung machine to pump a custom-made solution, dubbed OrganEx, into the pigs' bodies ⬆️. The pigs' hearts started beating. The pigs weren't revived, but the technology might be useful for human transplantation and in limiting damage to hearts from heart attacks, and to brains from strokes.

What are some record-breaking biological discoveries of 2022?
Biggest single-celled bacterium
Averaging about a centimeter long and visible to the naked eye, Thiomargarita magnifica, is a newfound bacterium, which lives in the mangrove forests of the Caribbean’s Lesser Antilles, is about 50 times larger than other species of big bacteria and about 5,000 times larger than typical bacteria. Why this species evolved into such a giant is unknown.
Largest fish colony 🐟
Deep off the coast of Antarctica, a breeding colony of some 60 million nests of Jonah’s icefish (Neopagetopsis ionah) is stretching across at least 240 square kilometers of seafloor.
The world's smallest new snail species 🐌
In Southeast Asia, scientists discovered two new snail species, smaller than any seen before. They dubbed the smallest one, measuring only 0.6 millimeters in diameter, Angustopila psammion, as “psammion” derives from the ancient Greek word for “grain of sand.”

What are new details of the dino-killing impact discovered in 2022?
The impact that ended the age of 🦖🦕 some 66 million years ago was the worst single day for the life on Earth.
A 6.5-mile-wide asteroid called Chicxulub slammed into the waters off what is now Mexico, triggering a mass extinction that killed off more than 75 % of Earth’s species!
📌In 2022, researchers were studying a set of fossil fish that died in the blast and concluded the asteroid struck during spring in the Northern Hemisphere.
📌They provided another glimpse of the asteroid’s devastation: Within minutes of the impact, rocks that formed in the extreme temperatures rained down more than a thousand miles from the crater’s center.
📌Scientists also announced that they had found signs of another possible undersea crater off the coast of West Africa that is about the same age as Chicxulub—perhaps evidence that a fragment of the incoming asteroid broke off and smashed into Earth separately.

What are two big space breakthroughs of 2022?
Closest black hole ⚫️
By sifting through data released by the Gaia spacecraft, astrophysicists discovered in 2022 a black hole that’s just over 1,560 light-years from Earth. Dubbed Gaia BH1, it’s about twice as close as the previously nearest known black hole.
But that record may not stand, as about 100 million black holes are predicted to exist in the Milky Way and even closer black holes may turn up in the next years.
The Space Innovation of the Year 🔭
NASA’s James Webb Space Telescope, the giant infrared instrument now parked a million km from Earth, was named the Innovation of the Year.
Its first images were finally presented in July, revealing an unprecedentedly detailed view of the cosmos, “the deepest view of the universe ever” according to specialists.
The telescope is working through a long list of planned observations, exploring everything from the oldest galaxies to the atmospheres of distant exoplanets.

What is astronomy?
✔️ Astronomy is the study of the universe, the celestial objects that make up the universe, and the processes that govern the lifecycle of those objects.
🔭 Astronomy is largely an observational science. Astronomers use the electromagnetic radiation emitted from stars and other celestial objects, which can include visible light, UV, infrared, and X-rays. Because the light from these objects is the primary means to study them, one of the most important tools for an astronomer is the telescope.
♾ Given the size of the universe (which could be infinite), astronomy is an enormous field.
🌠🌌The celestial objects that astronomers study include stars, galaxies, nebulae, and supernova.
🔙 Because of the enormous distances between Earth and other objects, when astronomers look farther away, they are also looking back in time. This is because of the amount of time it takes the light we see to travel from the source to us here on Earth.

Who were the first great astronomers?
Astronomical observation begins with the early civilizations of Mesopotamia, where prominent constellations are recognized and named soon after 3000 BC.
Babylonians
The sky-watchers of Mesopotamia identify the five wandering stars, which with the sun and moon form the seven original 'planets' (Greek for 'wanderers').
Within Mesopotamia the Babylonians, flourishing from the 18th century BC, are considered to be the first great astronomers. The minutes and seconds of modern astronomical measurement derive from their number system.
Greeks
From the 6th century BC the Greeks make significant advances in astronomy: their analytical approach to the heavens leads to early insights of great brilliance.
They are first to produce an astronomical theory in which a circular earth revolves on its own axis as well as moving in an orbit. The theory derives in part from the need to locate the great fire which they believe fuels the universe.

What is the zodiac?
The zodiac is the line on the celestial sphere (the full pattern of stars as seen in the night sky) along which the sun seems to move during a full year. The position of the sun on any day can be discovered by observing which stars are just above the horizon at the point where the sun is about to rise or has recently set. They will be the same group of stars at the beginning or end of the same day, even though appearing in the east at dawn and in the west at dusk - for the sun's position in relation to the stars, as seen from earth, hardly changes within a day.
The concept of the zodiac was introduced by the Babylonians who realized that the zodiac can serve as a yardstick of celestial time if divided into recognizable and equal segments. They selected twelve constellations to represent these segments and gave them the names of animals.
The Greeks later provided the term for the zodiac when they describe it as the 'animal circle' (zodiakos kyklos).
In succession these constellations are ⬇️
♈️ Aries (the Ram)
♉️ Taurus (Bull)
♊️ Gemini (Twins)
♋️ Cancer (Crab)
♌️ Leo (Lion)
♍️ Virgo (Virgin)
♎️ Libra (Scales)
♏️ Scorpio (Scorpion)
♐️ Sagittarius (Archer)
♑️ Capricornus (Goat)
♒️ Aquarius (Water Carrier)
♓️ Pisces (Fishes)

What is astrology and is it a science?
Astrology can be defined as the study of the connection between celestial activity phenomena and earthly events.
In some context astrology is also described as the primitive study of celestial bodies, which formed the basis of astronomy and began with the ancient civilizations.
Those who practice astrology are called astrologers.
Astrology maintains that each person is born under a particular sign of the zodiac.
Some divide astrology in 3️⃣ branches:
🟢 Mundane A. (predictions about national and international affairs)
🔵 Interrogatory A. (predictions about subject’s life)
🟣 Natal A. (predictions based on the date of a person’s birth)
Even though astrologers use mathematics and astronomy to make their calculations, there is no evidence that astrological predictions are accurate and thus astrology is a pseudoscience.
ℹ️ A pseudoscience is a field that pretends to use scientific methodology, but does not follow the scientific method.

What is calendar?
A calendar is a system of organizing days for social, religious, commercial, or administrative purposes.
This is done by giving names to periods of time, typically days, weeks, months, and years.
A date is the designation of a single, specific day within such a system.
Periods in a calendar are usually, though not necessarily, synchronized with the cycle of the sun or the moon.
Many civilizations have devised a calendar, usually derived from other calendars on which they model their systems, suited to their particular needs.
🗓 A calendar is also a physical device. This is the most common usage of the word.
📱💻 Other similar types of calendars can include computerized systems, which can be set to remind the user of upcoming events and appointments.
📝 A calendar can also mean a list of planned events, such as a court calendar.
The English word calendar is derived from the Latin word ‘kalendae’, the Latin name of the first day of every month.

What is the world’s oldest calendar?
🏴 In 2013, archeologists announced the discovery at Warren Field in Scotland ⬆️ of what they claim as the world’s oldest calendar – a series of 12 large pits that were designed to mimic the various phases of the moon and aligned perfectly on the midwinter solstice in a way that would have helped the Mesolithic hunter-gathers keep accurate track of the passage of the seasons and the lunar cycle.
At nearly 10,000 years old, these pits are pre-dating by several thousand years the Bronze Age monuments in Mesopotamia.
The geophysical evidence suggests the pits had been periodically reshaped until at last the calendar-monument seemed to fall out of use around 4,000 years ago.
First discovered by aerial photography in 2004, their significance was recognized only 10 years later, using the latest-generation remote-sensing technology and software that worked out the positions of sunrises and sunsets in the landscape 10,000 years ago.
