Yeah it’s probably been doing that a long time, but we didn’t notice. • A person put a grape cut in half in the microwave to discover that it caught fire. Scientists later used that experiment in their physics studies. Okay, to be clear, let’s not go blowing up grapes. 2012 – The year that made us believe that the world would come to an end. Oops, not so fast. • Venus passed directly between the Sun and the Earth. This won’t happen again until 2117. • NASA landed a rover on Mars called Curiosity.

And I’m sweating sitting here thinking about it. • A study in social psychology concluded that fonts which are harder to read are more convincing. This is because readers are forced to slow down, read things word-by-word, and spend longer thinking about the facts. • A full lab-grown burger was finally made. It took 2 years to produce and it cost 325,000 bucks. Cows across America began to have hope. 2014 • Scientists discovered that water vapor was coming out of the dwarf planet “Ceres” – that’s also the largest asteroid in our solar system. • Archaeologists excavated a site that was below two ancient temples in central Rome. There, they found votive offerings, figurines and drinking vessels too. Maybe even a Vespa. • NASA’s MAVEN Spacecraft reached Mars for its mission to study the red planet’s atmosphere. • A probe named Rosetta let its lander loose on the 67P comet. It observed the comet’s closest approach to the sun and studied its surface. • Scientists studied 48 bird species for over 4 years, and they finally announced that according to genetics, birds evolved from dinosaurs. • Researchers studied a pink spot on the head of leatherback sea turtles. As it turned out, it acts as a biological clock which alerts them about changes in sunlight and seasons. • Inside the constellation of the Giraffe (yup, seriously), scientists discovered two massive blue stars merging into one. 2015: It was all about space this year • The spacecraft named Messenger had been sent to study Mercury’s matter, and after 4 years of orbiting the planet, it crashed onto its surface. • 10 years after NASA’s April Fools joke that water existed on Mars, scientists discovered that there’s actually liquid water occasionally flowing on Mars despite its freezing temperature. • A guy named Sven held the world record for the longest birthday ever. His day lasted around 46 hours as he crossed multiple time zones to achieve his goal. • NASA’s New Horizons spacecraft flew by Pluto and gave us a closer look at what it looks like.

Those waves came when two neutron stars collided. 2018: • Experts found that citrus fruits go all the way back to the foothills of the Himalayas. • There were 65,000-year-old cave paintings in Spain made by the Neanderthals.

Another one was born two years ago and got the name Forest. I can’t wait for the little “pea” to arrive. Hey! What name would you give to a green colored puppy? Let me know down in the comments! • Giraffes with dark spots were found to be more dominant than the ones with lighter colored spots. • Another research about bees showed that they can do math. They can add, subtract, and understand the concept of Zero. • Mars Opportunity Rover’s mission ended after 15 years because of a powerful sandstorm that damaged all communications. • A stolen Picasso painting was finally found in March of 2019 – it was recovered after 20 years by an art detective. • We had the first photo of a black hole that made the Internet go crazy. It’s 6.5 billion times the mass of the Sun and 55 million light years away. • Vantablack is a material that used to be the darkest human-made object in the world. But now, MIT engineers developed something 10 times darker. It doesn’t have a name yet, but it absorbs more than 99.99% of light. Can’t wait to see what happens this decade!
