The imprints of explorers on the moon still may persist in at around a century's time.
Since the moon doesn't have an atmosphere, neither the Apollo astronauts' or future Artemis moonwalkers' imprints will be eroded or washed away when they eventually reach the moon.
So long as they aren't removed on purpose, their rover prints, footprints, and other imprints will remain on the moon for a very long time. Nevertheless, they won't be there indefinitely. The moon is still a changing landscape. The moon is actually continually being hit by "micrometeorites," indicating that erosion is still taking place there, albeit slowly.
The weight of the whole human race would fit in a teaspoonful of neutron stars.
This one is a little confusing. Nearly all of neutron stars' mass is concentrated into a small radius where it forms neutron stars.
In fact, a teaspoonful of this substance would be heavier than all of humanity combined, weighing almost a trillion pounds.
When two pieces of the same sort of metal come into contact in space, they will bond and become inextricably attached.
The term "cold welding" refers to this astonishing phenomenon. As a result, the lumps of metal combine because their atoms lack a mechanism to recognize one another as separate chunks of metal.
On Earth, there are air and water between the parts, therefore this couldn't happen. The impact on building spaceships and the use of metal in vacuums in the future is significant.
In the known universe, there are an incalculable amount of stars.
In essence, scientists are unsure about the precise number of stars in the cosmos. The number of stars in our galaxy, the Milky Way, is currently estimated by scientists, who then multiply that figure by their best estimates as to the number of galaxies in the universe. A "zillion" is defined as "an indeterminately huge number" by NASA, who can only firmly state that there are zillions of stars after all that tasty mathematics.
It was estimated to be 70 sextillion, or 70,000 million million million, by an Australian National University study. So much. Unquestionably a lot
The galaxy's center is overflowing with alcohol, has a rum-like aroma, and tastes like raspberries.
We aren't kidding. Back in 2009, scientists studying a massive cloud of gas and dust in the Milky Way's center discovered an unexpected discovery: the cloud was crammed with ethyl format, a substance that tastes and smells deliciously like rum and gives raspberries their flavor.
In addition, another nearby cloud region is noteworthy for being rich in ethanol, also known as ethyl alcohol, which is the substance that we common mortals use to make alcoholic beverages.
In fact, it has enough alcohol in it to (cue the drum roll) make 300,000 pints of beer for every person on Earth every day for the next billion years!
The sun makes up 99 percent of the mass of our solar system.
She is large, that's for sure.
The sun, our star, makes up an enormous 99 percent of the mass of our entire solar system due to its incredible density. This enables it to exert a greater gravitational pull than any other planet.
About 600 million tonnes of hydrogen are fused into helium every second by the sun. As a by-product, it also transforms around 4 million tonnes of matter into energy.
The Earth and everything on it will be engulfed by the sun when it turns into a red giant and dies. Thankfully, it won't happen for another 5 billion years.
Compared to a Venus year, a Venus day is longer.
Although it may be challenging to comprehend, this is actually the case. The length of a planet's "day"—the amount of time it takes to complete one full rotation on its axis—and its "year"—the amount of time it takes to complete its orbit—are both units of measurement.
It takes the planet Venus 243 Earth days to complete one full rotation of its axis. However, due to its close proximity to the sun, it has a short year—about 225 Earth days. This implies that a day on Venus is slightly longer than a year there.
Since its discovery, Neptune has only made one journey around the Sun.
Neptune was first found in 1846, and it took it a torturous 165 years to complete one full cycle around the Sun. Its first post-discovery orbit was completed in 2011, which was 11 years ago.
"Extinct planet" To equal this, Pluto still has a long way to go and hasn't come close to finishing a full 248-year orbit since its discovery in 1930.
