Does the planet Jupiter actually have a terrestrial surface to it, like Earth?
Jupiter, the largest planet in our solar system, is often referred to as a gas giant due to its composition, which is predominantly hydrogen and helium. Unlike Earth,…
Why when summiting Mount Chimborazo (the tallest mountain from the center of the Earth, being the closest to space) not require oxygen to be worn for hikers at the top, but Mount Everest does?
Both can be scaled without oxygen. The atmosphere-to-sea-level ratio determines how dangerous things get. Everest climbs to 29,029 feet (8,848 meters), while Chimborazo’s peak is 20,548 feet (6,263…
When the Sun finally eats us, what will the last days on Earth be like?
My friend, Earth will be a hell hole long before we meet the true end. You see, the Sun ain’t getting any younger. It’s a middle-aged star slowly…
NASA has revealed a stunning first photo of the distant world of Ultima Thule, the most distant object that humanity has ever explored. Was it as they expected?
his is the back side of Jupiter’s moon Callisto: A dark, icy, cratered ball. Pretty much what they expected. And possibly the last thing in the Solar System that looked…
If water is made up of 2 atoms of hydrogen & 1 atom of oxygen, then why can’t we manufacture water?
We can! Here is a giant water-making machine in action, making 1.8 tons of artificial water every second: At this moment, 200 kg hydrogen and 1600 kg oxygen…
Is it true that on Saturn’s moon Titan, you could walk around without a pressure suit, just heavy parka and oxygen tanks?
Yes, it is true but for a very limited amount of time! Without a completely airtight, heated suit and heated air supply? No. True, it would not have…
If you lit a match on Jupiter, would the planet explode?
Jupiter is 90% hydrogen, but the remaining 10% is mostly helium. A match is composed of carbon, which reacts with heat to combine with oxygen to create CO2….
If I was in a room made of mirrors, and I shut off the lights, why wouldn’t the residual light continue to bounce off the mirrors and illuminate the room?
No. Because no mirror is 100% efficient. Every time it reflects light it absorbs a small amount of photons. Also, once you start to look, the room will…
What would Jupiter look like to us from Earth if Venus and Jupiter switched spots?
eplace Venus (67 million miles from the sun) with Jupiter, a planet with 390 times the mass of Venus. And roughly 11 times the diameter. Now, you would…
How deep is the sand of the Sahara? What is below it? Is it a gradual transition, or is it like pure sand dumped directly on some previous flat surface?
The Sahara, Arabic for desert, stretches across North Africa. The Sahara is the world’s largest non-polar desert, over 9,000,000 km² (3,500,000 mi²), which is about the same size as the…
