The Drake Equation: Estimating Extraterrestrial Life
American astronomer Frank Drake devised the Drake Equation to statistically estimate the likelihood of intelligent extraterrestrial life. This equation considers factors such as the number of stars formed in our galaxy each year, the probability of those stars having planets, and the number of planets that could support life. It also takes into account the probability of life actually emerging, the likelihood of that life evolving into an intelligent civilization, the chances of such a civilization developing communication technology, and the duration that a communicative civilization can survive without being destroyed.

Discovery of UY Scuti In the 1860s, astronomers discovered an enormous star about 9,500 light-years away. Its name is UY Scuti, and its diameter is a staggering 1,708 times that of the Sun. In comparison, the Sun appears almost invisible next to it. If UY Scuti were placed at the Sun’s position, its size would extend beyond Earth's orbit, reaching all the way to Jupiter.

Firing a Gun on the Moon If you were to fire a gun at Earth from the Moon, there’s no need to worry. Since the Moon has a weak gravitational pull, the bullet would not escape its orbit. Instead, it would travel about 13,000 feet before falling back to the lunar surface. However, the situation changes drastically if a gun is fired toward Earth in open space. Firing a Gun in Open Space In the vac...

The Expanding Universe and Galactic Drift Currently, galaxies are in a delicate balance between gravitational attraction and cosmic expansion. However, as time passes, the universe will continue to expand, causing galaxies to drift further apart while the influence of dark energy grows stronger. The Darkening Universe Stars will eventually reach the end of their lifecycles, making the universe ...

Introduction Olympus Mons: The Largest Volcano in the Solar System Olympus Mons is the largest volcano in the solar system, located on Mars. It stands at an incredible height of approximately 22 km, making it 2.5 times taller than Mount Everest, the highest mountain on Earth. Its width spans around 600 km, comparable to the size of an entire country. Geological Factors Behind Its Size One of th...

The Observable Universe and Its Origins The universe began as a single point of light, and the region we can observe is called the "observable universe." But what lies beyond it? In the 1930s, astronomer Edwin Hubble made a groundbreaking discovery: stars and galaxies were moving away from Earth. More than that, the entire universe was expanding. If we reverse this expansion, we arrive at the c...

Doubling Earth's Size Doubling Earth's size would expand the polar radius and thin the atmosphere. However, the planet would still closely resemble the Earth we know. At Three Times Its Size At three times its size, drastic changes begin. The Moon rapidly approaches, and its fragments surround Earth, causing massive sea level rises that submerge most continents. Over time, the planet stabilizes...

The Journey Begins: Traveling at Light Speed If a spacecraft could travel at the speed of light, Earth would instantly shrink into a tiny blue dot. Increasing the speed to 800 times the speed of light would allow us to escape the solar system quickly, but interstellar travel would still be difficult since the distance between stars spans hundreds to thousands of light-years.

Immediate Effects on the Body If a human is exposed to space without protection, they wouldn't instantly freeze or explode as seen in movies. However, survival would only last a few seconds. With no atmospheric pressure, the body would swell like a balloon, but the skin's elasticity would prevent it from bursting. Meanwhile, the gas inside the intestines would expand, causing severe pain. The a...
