It Seems Hard to Imagine Something Bigger Than Everest or More Extensive Than the State of São Paulo. But This Place Exists — and It Is on Mars. Olympus Mons Is the Largest Volcano Ever Recorded in the Solar System and Impresses with Its Colossal Numbers, Visible Only from Space.

Olympus Mons Is Not Just Big. It Is Colossal. Located on Mars, It Is the Largest Volcano Ever Recorded in the Entire Solar System. To Get an Idea, Its Base Measures About 600 Kilometers in Diameter. That Is More Than the State of São Paulo Itself.

The Height Is Also Impressive. The Summit of Olympus Mons Is 21 Kilometers Above the Martian Surface.

Therefore, It Is More Than Twice the Height of Mount Everest, Which Is the Tallest Mountain on Earth. When Compared Side by Side, Everest Seems Small in the Face of the Martian Grandeur.

ARTICLE CONTINUES BELOW

It Seems Flat, But It Is Not

The Most Important Thing Is That Olympus Mons Challenges Visual Perception. If Someone Were at Its Highest Point, They Would Not Be Able to See the Edges. This Happens Because the Relief Is So Wide That the Curvature of the Mountain Itself Hides the Horizon.

Another Curious Detail: the Top of Olympus Mons Is Not Visible from Anywhere Else on Mars. This Is Because It Is So Large and So Elevated That Its Own Structure Blocks the View.

In Other Words, Even in Open Field, It Would Be Impossible to See Its Summit from Afar.

Therefore, to Observe the Full Extent of This Geological Formation, There Is Only One Way: to See from Space. From Martian Orbit, Images Show the True Size of the Volcano. That Is When Its Absurd Scale Is Understood.

A Non-Welcoming Environment

If Someone Decided to Climb Olympus Mons, They Would Need to Be Very Well Prepared. And With Special Equipment. This Is Because, at the Top, the Atmospheric Pressure Is Extremely Low. There Is No Oxygen and the Temperature Is Extremely Cold.

Moreover, Since Mars Has a Thin Atmosphere, Protection Against Radiation Is Minimal. This Would Make Staying Up There Extremely Dangerous.

Even With All the Beauty of the Place, a Walk on Olympus Mons Would Be Impossible Without Space Suits and Life Support.

And the Sky? At the Top, the Sky Would Appears Dark. This Happens Because the Air Layer Is So Thin That Sunlight Does Not Scatter Like on Earth.

The Landscape Would Be Silent, Without Wind, and with a Flat Horizon As Far As the Eye Can See — or Rather, As Far As the Curvature Allows.

You Would Not Even Notice That You Are at the Top

One of the Most Curious Things About Olympus Mons Is Precisely This: Even at the Highest Point, It Would Be Hard to Notice. The Relief Around Would Seem Continuous.

Without Visible Peaks or Marked Differences in Elevation, the Feeling Would Be Similar to Being on a Plain. A Plain in the Sky.

This Makes the Experience of Being on Olympus Mons Different from Any Mountain on Earth. In Fact, It Would Be More Like Being on an Infinite Elevation.

Everything Would Seem Flat. Nothing Would Indicate That You Are on Top of the Largest Volcano in the Solar System.

For All These Reasons, Olympus Mons Is Considered a True Silent Giant of Mars. It Has Not Erupted for Millions of Years, But Its Presence Continues to Dominate the Red Planet.

And Even with All Current Technology, the Only Way to See It Completely Is from the Outside. Literally.

Mother and daughter build a 70 m² house with more than 8,000 discarded glass bottles and impress with their creativity; known as the Casa de Sal, the property is located on Itamaracá Island, in Pernambuco.

Workers were opening a new road connection near the Marginal Tietê when they found, in the underground of the construction site, remnants of locomotives, wagons, and boilers from the 19th century linked to the forgotten history of Lapa.

Instead of burning or burying old tires, an American city is transforming about 2,000 of them into the street itself, paving its first sections with a quieter and more durable rubber asphalt.

China transforms desert-devastated area into the world’s largest artificial forest, planting trees for 60 years, blocking sand that reached Beijing, and creating a “green lung” of 92,000 hectares in a region once considered lost.

Greek island offers free housing for volunteers, but there’s a condition: you need to take care of rescued cats.

China has deployed snake-shaped robots to slide along power lines, where they have already inspected over 130 kilometers of cables using cameras and sensors to detect damaged wires, worn-out parts, and overheating.

Engineers want to carve through Africa with a giant canal to bring water from the world’s second-largest river to a dying lake on the edge of the Sahara Desert that has already lost 90% of its water.

Declassified Pentagon files reveal that a strange “mothership” released a swarm of mysterious objects near a secret United States base.

Enigmatic code on a silk dress puzzled experts for over 140 years, until it revealed an unexpected connection with telegraph, climate, and Victorian meteorology.

How much does a gas station owner earn? A business that seems like a money-making machine can generate R$ 1.5 million per month and still profit only R$ 40,000, while the real earnings come from convenience, car wash, and extra services.

Chestnuts seem rich in minerals, but a study by Unifesp simulated human digestion and showed that the body only absorbs part of the copper and magnesium.

Desert sand, previously discarded for being too smooth for concrete, becomes an ecological brick in the United Arab Emirates, dispensing with Portland cement, curing at room temperature, and attempting to transform dunes useless for construction into raw material for a new arid engineering.
