Would your mobile phone be powerful enough to get you to the moon?
Many people who are old enough to have experienced the first moon landing will vividly remember what it was like watching Neil Armstrong utter his famous quote: “That’s one small step for a man, one giant leap for mankind.”. Half a century later, the event is still one of the top achievements of humankind. Despite the rapid technological advances since then, astronauts haven’t actually been back to the moon since 1972.
Red, white but rarely blue – the science of fireworks colors, explained
In the earliest days of the United States, John Adams wrote to his wife Abigail about the celebration of independence, “It ought to be solemnized with Pomp and Parade, with Shews, Games, Sports, Guns, Bells, Bonfires and Illuminations from one End of this Continent to the other from this Time forward forever more.” “Bonfires and illuminations” refer directly to what we know as pyrotechnics and firework displays.

The Most Efficient Way to Explore the Entire Milky Way, Star by Star
It seems like the stuff of dreams, the idea that humanity will one day venture beyond the Solar System and become an interstellar species. Who knows? Given enough time and the right technology (and assuming there’s not some serious competition), we might even be able to colonize the entire Milky Way galaxy someday. And while this seems like a far-off prospect at best, it makes sense to contemplate what a process like this would entail.
High-value opportunities exist to restore tropical rainforests around the world – here’s how we mapped them
The green belt of tropical rainforests that covers equatorial regions of the Americas, Africa, Indonesia and Southeast Asia is turning brown. Since 1990, Indonesia has lost 50% of its original forest, the Amazon 30% and Central Africa 14%. Fires, logging, hunting, road building and fragmentation have heavily damaged more than 30% of those that remain.
Four surprising technological innovations that came out of the Apollo moon landings
NASA’s Apollo program was one of the most challenging technological achievements in the 20th century. Beyond the space race and exploration, it contributed to several inventions and innovations that are still having an impact on our lives. But at the same time, there are several myths regarding what technologies actually came out of it.

Who Wants to be a Trillionaire? Mission to Psyche Could Uncover Tons of Precious Metals!
It has been said that within the next quarter century, the world’s first trillionaires will emerge. It is also predicted that much of their wealth will stem from asteroid mining, a burgeoning space industry where minerals and volatile compounds will be harvested from Near-Earth Asteroids. This industry promises to flood the market with ample supplies of precious metals like gold, silver and platinum.
How can you tell if another person, animal or thing is conscious? Try these 3 tests
How can you know that any animal, other human beings, or anything that seems conscious, isn’t just faking it? Does it enjoy an internal subjective experience, complete with sensations and emotions like hunger, joy, or sadness? After all, the only consciousness you can know with certainty is your own. Everything else is inference. The nature of consciousness makes it by necessity a wholly private affair.

How A Historic Jupiter Comet Impact Led to Planetary Defense
Twenty-five years ago, humanity first witnessed a collision between a comet and a planet. From July 16 to 22, 1994, enormous pieces of the comet Shoemaker-Levy 9 (SL9), discovered just a year prior, crashed into Jupiter over several days, creating huge, dark scars in the planet’s atmosphere and lofting superheated plumes into its stratosphere.
Diving into cold water can be deadly – here’s how to survive it
Many will have read the news story about the sad death of Cameron Gosling who died from cold water shock after jumping into the River Wear on a hot summer’s day. Sadly, Cameron’s death is not an isolated case. About 400 people die annually in the UK as a result of being immersed in cold water – more than die from cycling accidents or fire. Most of the casualties are males under 30 years of age, and most are reported to be good swimmers.

Why plants don’t die from cancer
Chernobyl has become a byword for catastrophe. The 1986 nuclear disaster, recently brought back into the public eye by the hugely popular TV show of the same name, caused thousands of cancers, turned a once populous area into a ghost city, and resulted in the setting up of an exclusion zone 2600km² in size.
