For more than five decades, Eugene Cernan has held a title he once hoped another astronaut would take from him.

Cernan was the last human to walk on the Moon, during Apollo 17 in December 1972—NASA’s final crewed lunar landing of the Apollo era.

His journey to the Moon was part of a remarkable three-flight career. He flew on Gemini 9A, Apollo 10, and Apollo 17, becoming the only person to travel to the Moon twice and one of only 12 people to walk on its surface.

On December 14, 1972, Cernan climbed back into the lunar module after completing humanity’s final lunar surface excursion. The footprints he and Harrison Schmitt left behind remain on the Moon, preserved in the lunar soil because there is no wind or rain to erase them.

Cernan died in January 2017 at age 82. He had spent years hoping that humanity would return to the Moon and that another astronaut would eventually take away his distinction as the last person to walk there.

More than 50 years later, those footprints are still waiting for the next generation of explorers.

Do you think humans will walk on the Moon again during your lifetime?

Four Amazing Facts About Our World
From humans reaching the Moon to the evolution of life, Earth’s changing climate, and the science behind our planet’s shape—these are some fascinating facts that show how much we’ve learned about our world. NASA confirms that Apollo 11 achieved the first crewed lunar landing in 1969, while Earth is a roughly spherical planet with a layered interior and a dynamic atmosphere. �

What Lies Beneath Our Feet? The Anatomy of Earth

Earth may look like a solid world from the surface, but deep beneath our feet, it is divided into several distinct layers—each with different temperatures, materials and properties.

🌫️ Atmosphere — 0–100 km
The gaseous layer surrounding Earth, where weather occurs and where we live.

Crust — ~5–70 km
Earth’s thin, solid outer layer. Oceanic crust is generally thinner, while continental crust can be much thicker.

Upper Mantle — beneath the crust to ~410 km
Made mostly of hot, solid rock that can slowly flow over geological timescales.

Transition Zone — 410–660 km
A region where minerals in the mantle undergo changes caused by increasing pressure and temperature.

Lower Mantle — 660–2,890 km
The largest layer of Earth’s interior, composed of extremely hot, high-pressure rock.

Outer Core — 2,890–5,150 km
A layer of liquid iron and nickel. Its movement generates most of Earth’s magnetic field.

Inner Core — 5,150–6,371 km
A solid sphere made mainly of iron and nickel, kept solid by the enormous pressure despite temperatures comparable to the surface of the Sun.

Earth’s center is about 6,371 km beneath the surface.

And here's the amazing part: humans have never drilled anywhere close to Earth's mantle, let alone its core. We learn about these hidden layers mainly through seismic waves produced by earthquakes and other geophysical measurements.

Everything we know about Earth’s deepest interior comes from reading the signals traveling through a planet we can barely scratch.

Humanity has reached beyond the Sun’s protective bubble!
Voyager 1 crossed the heliopause and entered interstellar space in 2012, followed by Voyager 2 in 2018. These remarkable spacecraft continue their journey far beyond the planets, sending valuable scientific data from the distant reaches of space.
A reminder of how far human exploration has traveled—and how much of the universe remains unknown.

Astronomers have discovered a truly young planet!
Elias 2-24 b is thought to be less than a million years old and is still forming around its young star.
Studying such young worlds can help scientists understand how planets are born and how planetary systems develop over time.

Voyager 1 is on an incredibly long journey beyond our Solar System!
Launched in 1977, Voyager 1 continues traveling through interstellar space. The Oort Cloud is thought to extend far beyond the planets, making its full journey truly mind-boggling.
Imagine traveling for hundreds of years just to reach the outermost regions of our cosmic neighborhood! ✨

AI and the Future of Mathematics
AI is making impressive progress in solving complex mathematical problems. In September 2026, OpenAI reported an AI-assisted result involving the famous Navier–Stokes problem, one of the Millennium Prize Problems. However, the mathematical community is still examining and discussing the proof, so the result should be viewed as an ongoing scientific development rather than a completely settled story. �

A Galaxy Shaped Like the Infinity Symbol?
NASA’s James Webb Space Telescope helped astronomers study the unusual “Infinity Galaxy,” formed by two galaxies interacting in a striking ring-like structure. At the center is a region of glowing gas containing evidence of a possible supermassive black hole. Scientists are investigating whether this black hole could have formed through the direct collapse of a dense gas cloud. �

The discovery offers scientists a fascinating look at how galaxies and supermassive black holes may form and evolve.

A New Supply Mission Is On Its Way to the International Space Station!
Russia’s uncrewed Progress 96 cargo spacecraft launched on September 16, 2026, carrying about three tons of food, fuel, and essential supplies for the ISS crew. NASA reports that the spacecraft is scheduled to dock with the station on September 19.

Meet the Telescopefish — one of the strangest creatures found in the deep ocean!
Its unusual eyes, long body, and sharp teeth help it survive in the dark waters where sunlight barely reaches. Deep-sea animals have evolved some truly fascinating adaptations to life under extreme conditions.
Nature never stops surprising us!
