The neutron stars are the tiniest and densest stars to be known in the entire universe. They only have the radius of about 10 kilometres and the mass few times more than that of the sun. They can rotate up to 60 times per second. These stars spin as fast as 600 to 712 times because of their physics. Interesting, isn’t it??

Diamonds are without a doubt the Milky Way galaxy’s best buddy. Neptune, Uranus, Jupiter, and Saturn have all been studied for their ability to create diamonds. The atmospheres of all four planets are under such severe pressure that carbon atoms can crystalize and transform into diamonds. Scientists could generate the circumstances in a laboratory to show that this occurs on Neptune and Uranus. Separately, another group of experts believes it may rain up to 2.2 million pounds of diamonds on Saturn every year.

The United Nations signed the Outer Space Treaty in 1967, two years before astronauts first landed on the moon, to avert a dangerous game of claiming dibs on the moon or any planet. The treaty's highlights include a determination that "the research and use of outer space, including the moon as well as other celestial bodies, shall be carried out for the beneficial and in the interests of all countries," as well as a rule that treaty parties "shall not place in orbit around the earth any objects transporting nuclear weapons or any other types of weapons of mass destruction." That's certainly reassuring!

Billions of years ago, while Earth was still a spry young thing, it came into touch with Theia, a "Mars-sized planet." According to the Natural History Museum, the impact caused "almost all of Earth and Theia to melt and rebuild as one body, with a little fraction of the new mass spinning out to become the Moon as we know it." The mechanism by which the moon formed from the debris of the enormous collision is known as "rotational fission," and it was confirmed by Apollo astronauts when samples of moon rock were found to have isotopes identical to those found on Earth.

Every month of the year has a full moon, and each one has its own distinct name. The lunar phases have been used to keep track of each month for ages, from January's Wolf Moon through September's Harvest Moon and December's Cold Moon. According to National Geographic, "old societies all across the world have given these full moons names depending on the behavior of the flora, animals, or weather during that month." When you see a full moon in November, you may boldly point to the sky and wow your friends by pointing out the Beaver Moon.

China landed its Chang'e-4 spacecraft on the moon in 2019, but the crew didn't just land anywhere. The spaceship landed on the far side of the space-based entity, maybe wondering what all the hoopla was about. It was "the first spacecraft in history to try or complete a landing on this unknown region, which is never visible from Earth," according to history. The Chinese astronauts investigated the huge lunar craters on the frigid surface while there.

While it is hard for the typical individual to perceive, the moon is moving away from us. According to experts, the lunar body is migrating away from the Earth at a rate of 3.8 centimeters each year owing to gravity. "Tides raised in the seas produce drag and so reduce the Earth's spin rate," the site said, saying that the "resultant loss of angular momentum is compensated for by the Moon speeding up, and thus moving further away."

As study on the Earth's moon continues, NASA plans to establish a home away from home during the Artemis III mission, which is slated to arrive on the lunar surface in 2024. The Artemis Base Camp will allow astronauts to dwell on the surface for extended periods of time; nevertheless, selecting the ideal location will be critical to the base's success.

A volunteer for the Search for Extraterrestrial Intelligence received a 72-second transmission from a distant star system 120 light years away in 1977. Because it was loud and came from an area that no one had ever visited, the gentleman who got it scribbled "Wow!" next to the original printout of the signal. It is still known as the "Wow! Signal." The noise, according to researchers, was picked up by a passing comet.

A neutron star is the detritus of a huge star that has depleted its fuel. The dying star explodes as a supernova, while its core collapses in on itself owing to gravity, resulting in the formation of a super-dense neutron star. Astronomers use solar masses to measure the mind-bogglingly huge masses of stars and galaxies, with one sun mass equaling the mass of the Sun (that is, 2 x 1030 kilograms/4.4 x 1030 pounds). A typical neutron star has a mass of up to three solar masses packed into a sphere with a radius of around ten kilometres (6.2 miles), resulting in some of the densest stuff in the known cosmos.

The Sun, unlike the planets, is a massive sphere of hydrogen gas. As a result, different parts of the Sun rotate at different rates. Tracking the movement of sunspots across the surface allows you to see how fast the surface rotates. It takes 25 days for regions near the equator to complete one rotation, while features near the poles can take 36 days. And it appears that the inside of the Sun takes about 27 days.

Clyde Tombaugh, a 24-year-old research assistant at the Lowell Observatory in Flagstaff, Arizona, was the first to spot photographic evidence of the former eighth planet. The ashes of Tombaugh are on board the New Horizons spacecraft, which flew by Pluto on Tuesday. Pluto's existence was predicted 15 years before Tombaugh's discovery, with astronomer Percival Lowell even calculating its approximate position based on the irregularity of Neptune's orbit.

According to current New Horizons observations, Pluto has a diameter of 1,473 miles, whereas Earth's moon has a diameter of 2,160 miles. Pluto is 18.5 percent of Earth's size.

Disney's Pluto the dog debuted the same year as the former planet, although, contrary to common perception, the dog was named after Pluto the (ex)-planet, not the other way around. Walt Disney may have chosen the moniker to capitalise on the excitement around the new planet, according to Disney animators.

While Pluto's icy neighbours are to blame for the planet's demise, they are also part of what makes the New Horizons mission so interesting. Pluto contains hills and tiny mountains that virtually float across its surface, according to the most recent finding. It's strange and strange, but we're dealing with a very foreign place on the boundaries of the Solar System, after all.

Io's eruptions are caused by the immense gravity that the moon is subjected to due to its location in Jupiter's gravitational well. The insides of the moon tense and relax as it orbits closer and farther away from the planet, generating enough energy for volcanic activity. Scientists are still trying to figure out how heat spreads through Io's interior, making it difficult to predict where the volcanoes are based solely on scientific models.

Uranus appears to be a featureless blue ball at first glance, but upon closer inspection, this gas giant of the outer solar system is quite strange. For starters, the planet rotates on its side for reasons that scientists are still trying to figure out. The most likely explanation is that it was involved in one or more titanic collisions in the distant past. In any case, Uranus' tilt distinguishes it from the other planets in the solar system.

While Mars appears to be quiet now, we know that something caused massive volcanoes to form and erupt in the past. Olympus Mons is the largest volcano ever discovered in the solar system. The volcano is comparable to the size of Arizona, measuring 374 miles (602 km) across. It's 16 miles (25 kilometres) tall, or three times the height of Mount Everest, the world's tallest mountain.

If you thought the Grand Canyon was massive, wait until you see Valles Marineris. This massive system of Martian canyons is 2,500 miles (4,000 km) long, more than ten times the length of the Grand Canyon on Earth. Valles Marineris escaped the notice of early Mars spacecraft (which flew over other parts of the planet) and was only discovered in 1971 by the global mapping mission Mariner 9. And what a sight it was to miss — Valles Marineris is roughly the length of the United States!

Because the moon lacks an atmosphere, there is no wind or water to erode or wash away the Apollo astronauts' imprint. That implies their footprints, roverprints, spacecraft prints, and waste stuff will be maintained for a very long period on the moon. They will not, however, remain there indefinitely. The moon is still a changing environment. It is regularly pummelling with "micrometeorites," which indicates that erosion is still occurring on the moon, although slowly.

Giovanni Cassini, a famous Italian astronomer, discovered a massive blemish south of Jupiter's equator in 1665. This 'Great Red Spot,' as it is still known today, has been a source of debate among astronomers for centuries. Some believe the feature, which is large enough to hold 2-3 planets the size of Earth's diameter, is a massive storm. NASA scientists discovered this after the Voyager 1 mission completed a flyby of the planet in 1979.

Astronomers unearthed a diffuse core, also known as a fuzzy core, in Saturn after studying data from NASA's Cassini spacecraft, which focused on the planet's rings. Caltech's Christopher Mankovich, who co-authored a study about the findings published in Nature Astronomy in 2021, explained, "The fuzzy cores resemble sludge. As you move toward the planet's centre, the hydrogen and helium gas in the atmosphere gradually mixes with more and more ice and rock." "It's a bit like parts of Earth's oceans where the saltiness increases as you go deeper and deeper, creating a stable configuration," he added.

Apple's initial iPod included a small Easter egg. This game could only be accessible if you knew the correct sequence of buttons to press. "Go to the 'Around' menu and hold down the center button for about three seconds to play a Breakout (Pong) game while you listen." Breakout, the hidden game, is significant in Apple's history since it was a product on which both Steve Jobs and Steve Wozniak collaborated at Atari.

Richard and Maurice McDonald both the company's founders established and occupied a hot dog stand near the Santa Anita racecourse in Arcadia, California, the USA in the late 1930s. They launched a drive-in barbecue restaurant in San Bernardino, California, in 1940, which they converted into a burger establishment in 1948. Maurice and Richard McDonald owned the world's ninth-largest economy, with 27 billion dollars in income from McDonald's franchisees.
