One such planet is PSR J1719-1438 b, companion to a millisecond pulsar. It has a density at least twice that of lead, and may be composed mainly of ultra-dense diamond. It is believed to be the remnant of a white dwarf after the pulsar stripped away more than 99 percent of its mass.
Called 55 Cancri e, the planet is "possibly covered in diamond, rather than water and granite," scientists explained at the time. The exoplanet is twice the size of Earth but has eight times its mass.
Diamond Planet's Diamond Mass = 17,920,800,000,000,000,000,000,000 kilograms = Three Earth Masses (3 x 5,973,600,000,000,000,000,000,000 Kg) Raw Diamond Value/Kg = $1.5 million = $300/carat x 5 carats/gram x 1,000. Diamond Planet's Diamond Value = $26.9 nonillion = $26,881,200,920,800,000,000,000,000,000,000.
Traditionally we think of diamonds as forming from the intense pressures found in Earth's interior, but a number of the sturdy gems have also been found in meteorites from space -- and they're fundamentally different from their terrestrial counterparts.
Using data from NASA's Hubble and Spitzer Space Telescopes, astronomers found evidence that two exoplanets orbiting a star 218 light-years away are “water worlds,” where water makes up a large fraction of the entire planet.
It's a magenta-colored planet! Named GJ 504b, the planet is made of pink gas. It's similar to Jupiter, a giant gas planet in our own solar system. But GJ 504b is four times more massive.
Among the stunning variety of worlds in our solar system, only Earth is known to host life.
Psyche 16 is nestled between the orbits of Mars and Jupiter and is made of solid metal. As well as gold, the mysterious object is loaded with heaps of platinum, iron and nickel. In total, it's estimated that Psyche's various metals are worth a gargantuan $10,000 quadrillion.
Worldwide reserves are estimated to be some 1.2 billion carats. Russia has the largest reserves, estimated at some 650 million carats.
The Diamond Planet
The international team of astronomers who made the discovery told the journal Science that they believe the planet is slightly more massive than Jupiter but more than 20 times as dense.
Russia and the Botswana hold the world's largest diamond reserves, totaling 600 million carats and 300 million carats, respectively, as of 2022. Based on production volume, Russia and the Democratic Republic of Congo are.
The Golden Jubilee diamond
In 1997, the diamond was presented to the King of Thailand after it took specialists a few years to cut and polish. Today, the largest finished diamond is owned by the Royal Family of Thailand.
The British Royal Crown is the owner of the most costly diamond in the world. The Kohinoor gem is currently on exhibit as the main diamond of the Queen Mother's Crown at the HM Tower of London.
Weather and rains of molten glass
The weather on HD 189733b is deadly. The winds, composed of silicate particles, blow up to 8,700 kilometres per hour (5,400 mph). Observations of this planet have also found evidence that it rains molten glass, horizontally.
Scientists have found evidence of cubic zirconia in Moon rocks, showing that the universe not only holds diamonds, but its own fire-safe knock-offs. Space could be absolutely shimmering with precious stones, though Mao emphasizes that they probably aren't quite like the ones in earthlings' jewelry boxes.
Using data from NASA's Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star – the range of distances where liquid water could occur on a planet's surface. The world is 95% Earth's size and likely rocky.
The average concentration of gold in Earth's crust is 'very, very low,' at 4 parts per billion. In its elemental form, gold is significantly rarer than diamonds.
Diamond reserves have been stable in recent years at 2.3 billion carats, a sufficient level to sustain current annual production for the next 18 years. New pipeline and expansion projects along with currently operating facilities will generate around 172.3 million carats in 2025.
The Cullinan Diamond is the largest gem-quality rough diamond ever found, weighing 3,106 carats (621.20 g), discovered at the Premier No. 2 mine in Cullinan, South Africa, on 26 January 1905. It was named after Thomas Cullinan, the owner of the mine.
A 2009 NASA mission—in which a rocket slammed into the moon and a second spacecraft studied the blast—revealed that the lunar surface contains an array of compounds, including gold, silver, and mercury, according to PBS.
A conservative estimate is that there are 100 billion galaxies in the observable universe. There might be twice as many, but perhaps a lot of them are small or less likely to support life for various other reasons. as my estimate of the value of the observable Universe. That's $6 × 1025, or $60 septillion.
According to Forbes, 16 Psyche, a 140-mile-wide (226-kilometer-wide) asteroid could contain a core of iron, nickel, and gold worth $10,000 quadrillion. The scientists are trying to explore this asteroid for a great comparison of its composition versus Earth's.
Cosmologists aren't sure if the universe is infinitely big or just extremely large. To measure the universe, astronomers instead look at its curvature. The geometric curve on large scales of the universe tells us about its overall shape. If the universe is perfectly geometrically flat, then it can be infinite.
Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin based on its characteristics; also known by its Kepler Object of Interest designation KOI-7016.01) is a super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system ...
Question: Is there another planet like Earth? Answer: While there is no evidence of extraterrestrial life, scientists at NASA have recently discovered an earth-sized planet within the habitable zone of its star. The planet is called TOI 700 e.
