See if you can tell if these landscapes are on Earth or in another world.
We often take the beauty of the Earth and its otherworldly landscapes for granted.
But can you tell if this or that geological feature belongs to our planet or another object on it? solar system?
MailOnline has put together a selection of images from Earth and beyond to test your knowledge of whether you’re looking at our world or a world like it. Mars, Venus or one of the many distant moons in the solar system.
Of course, it could even be our own moon.
Take the quiz below and find out how you are doing. The answers are below each picture, including details of what you are looking at.
1. Earth or beyond?
Marslike: This landscape may be many people’s idea of what it looks like on the Red Planet.
While it may look like Mars, it is actually Spain.
Bardenas Reales is a semi-desert natural region or badlands of about 42,000 hectares in the southeast of Navarre. It is just over an hour from the city of Zaragoza.
The soils in Bardenas Reales are composed of clay, chalk and sandstone and have been eroded by water and wind.
This is what has created beautiful canyons, plateaus and other amazing forms, including isolated hills called cabesos.
Game of Thrones fans can also recognize the Dothraki Sea as the setting here.
2. Earth or beyond?
Water world? It looks like it could be a scene from one of the distant moons in our solar system.
Answer: It’s Earth again!
It may look like one of Saturn’s icy moons, but it’s actually in Brazil.
The Lencois Maranhensis National Park is made up of huge stretches of white dunes that criss-cross the landscape, punctuated by crystal clear lagoons that fill with rainwater from May to September.
Lençois is Portuguese for “sheets” after the way the white dunes appear.
The stunning scenery stretches 43 miles (70 km) along the coast and more than 30 miles (50 km) inland.
3. Earth or something else?
Sandy view: This series of images shows a mountainous area – but is it on Earth or in another world?
Answer: It’s over the edge!
These breathtaking images were taken on Titan, Saturn’s moon.
They may look like a sandy mountain range on Earth, but they were actually photographed by the European Space Agency’s Huygens probe, which landed on Earth in 2005.
The images show views north, south, east and west at five different heights above Titan’s surface.
Huygens was designed to collect data for several hours in the Moon’s atmosphere, as well as for a short time on the surface. He managed to send data for about 90 minutes after landing before contact was lost.
4. Earth or something else?
Scars: These frozen features could be somewhere on Earth, but are they really somewhere else?
Answer: It’s over the edge again
The enchanting red scars that criss-cross this landscape belong to Europa, the smallest of the four Galilean moons orbiting Jupiter.
They are actually cracks and ridges that represent faint lines in the Moon’s icy crust, which are accentuated and exacerbated by the swelling and falling tides due to Jupiter’s gravitational pull.
This image was taken by the US space agency. The Galileo spacecraft in the late 1990s.
5. Earth or something else?
Sunrise here or somewhere else? This desert landscape is very similar to the Martian.
Another landscape with a Martian view, but again on our planet.
Also known as the Valley of the Moon, Wadi Rum is a desert in Southern Jordan covering about 277 square miles (717 square kilometers).
There are red dunes, charming rock formations and valleys over a mile (1,700 meters) high.
In fact, the view is so similar to Mars that if you were to visit it, you’d be forgiven for thinking you survived what Matt Damon’s character did in The Martian when he was left to die on the Red Planet.
Popular with hikers and rock climbers, Wadi Rum Protected Area has been a UNESCO World Heritage Site since 2011.
6. Earth or beyond?
Clouds, volcanoes, mountains or something else? Is this a picture of Earth or another world in the solar system?
This one is perhaps a little easier. While you might argue that it either looks like evil, sun-drenched clouds or a view of some mountains on Earth, this is actually what it looks like on our planet’s evil twin, Venus.
The image has been dubbed “Crater Farm” by NASA because it shows a mysterious layering of volcanic activity and impact craters on the second planet from the Sun.
The picture was taken in the early 1990s by the Magellan space probe.
Although it looks mesmerizing, the scenery is best viewed from afar. That’s because Venus is a hellish world where surface temperatures are hot enough to melt lead and the atmosphere is saturated with carbon dioxide.
7. Earth or beyond?
Ice Cave: Is it on Earth, or perhaps one of the frozen moons orbiting Jupiter, Saturn, or Neptune?
Much has been said about how extraterrestrial life in our solar system could exist deep in the underground ocean on one of the icy moons of Saturn or Jupiter.
And that image above certainly looks like it’s some otherworldly watery tundra.
In fact, it captures the second largest glacier in Europe – the Vatnajokull glacier in Iceland.
This stunning natural wonder is home to many ice caves like the one above and is over 3,000 feet (900 meters) deep in some places.
This is not the only secret he keeps. The glacier actually hides several active volcanoes beneath its surface – and perhaps even more disturbing is that geologists believe an eruption is long overdue!
8. Earth or something else?
Eye of the Storm: Is it Jupiter, Venus or somewhere on Earth? Vibrant colors make it a stunning sight
Answer: It’s Earth again!
Surely you think that this colorful eyeball-like creature would feel better on Venus, Jupiter, or one of the distant moons of the solar system.
But it’s actually the Grand Prismatic Spring in Yellowstone National Park.
Mainly in Wyoming, the park also extends into parts of Montana and Idaho, with this thermal feature being the most photographed part.
The impressive colorful ring measures 200 to 300 feet (60 to 90 meters) in diameter and 121 feet (36 meters) deep.
This is a very popular location for microscopic organisms known as thermophiles, which thrive in hot environments.
The toughest of them live in the hottest water in the middle of the spring and are either colorless or yellow, while orange, brown and green thermophiles live in slightly cooler waters at the edge.
9. Earth or beyond?
Desert view: Another image very similar to that of Mars. But was it done on Mars or here on Earth?
After several previous Martian landscapes on Earth or on another world in our solar system, this one finally belongs to the Red Planet.
The image was taken by NASA’s Spirit rover, which was active from 2004 to 2010.
Since climbing Hill of Man, Spirit has spent more than four years exploring sites within this species, including the Comanche outcrop and the Home Slab area.
Muzh’s Hilltop is a wide plateau of windblown rock and sediment about 100 meters (300 ft) higher than the surrounding plains of Gusev Crater, where Spirit landed in January 2004.
10. Earth or something else?
Volcanic activity: Is it burning lava on Earth or somewhere like Jupiter’s moon Io
You might think that this landscape of burning lava looks more like Jupiter’s moon Io, which is the most volcanically active place in our solar system.
But in fact, this is one of the volcanic hotspots of our planet – Hawaii.
Though nowhere near as active as Io, which is littered with volcanoes capable of spewing plumes 90 vertical miles, one Hawaiian volcano does bear an uncanny resemblance to its sister fissure on Jupiter’s moon.
NASA scientists studied images taken by the Galileo spacecraft and determined that the Prometheus volcano on Io bears a resemblance to Kilauea, located on the Big Island.
Both havelong-lived eruptions and flows passing through lava tubes.
Where in our solar system could aliens exist? Mars, Jupiter’s moon Europa and Saturn’s moons Enceladus and Titan are among the worlds most likely to host extraterrestrial life, experts say.
For millennia, humanity has struggled with the idea that we are not alone in our solar system.
The assumption that aliens may exist goes back to philosophers in ancient times Greecebut it was the middle of the 20th century when people’s imagination really started to run amok – all of a sudden “little green men” were everywhere in popular culture.
Although the use of the phrase is believed to have originated in 1908, it was between the 1920s and 50s that green Martian characters were featured on the covers of science fiction magazines and later on television.
The reality is that if extraterrestrial life does exist in our solar system, it will be of a simpler variety, perhaps hidden in the clouds of Venus, under Marssurface or in the vast underground oceans of one of Saturnice moons.
But where else is the best place to find it? MailOnline is turning to a number of experts to find out.
