Scientists discovered Earth’s oldest rock on Moon
[vc_row][vc_column][vc_column_text]Scientists say they have discovered what may be the Earth’s oldest rock in a lunar sample returned from the Moon by the Apollo 14 astronauts.
An international team associated with Center for Lunar Science and Exploration (CLSE) in the US found evidence that the rock was launched from Earth by a large impacting asteroid or comet.
This impact jettisoned material through Earth’s primitive atmosphere, into space, where it collided with the surface of the Moon — which was three times closer to Earth than it is now — about four billion years ago, researchers said.
The rock was subsequently mixed with other lunar surface materials into one sample, according to the study published in the journal Earth and Planetary Science Letters.
The team developed techniques for locating impactor fragments in the lunar regolith, which prompted CLSE Principal Investigator David A Kring to challenge them to locate a piece of Earth on the Moon.
The researchers found a two-gramme fragment of rock composed of quartz, feldspar, and zircon, all commonly found on Earth and highly unusual on the Moon.
Chemical analysis of the rock fragment shows it crystallised in a terrestrial-like oxidised system, at terrestrial temperatures, rather than in the reducing and higher temperature conditions characteristic of the Moon.
“It is an extraordinary find that helps paint a better picture of early Earth and the bombardment that modified our planet during the dawn of life,” said Kring, a Universities Space Research Association (USRA) scientist at the Lunar and Planetary Institute (LPI).
It is possible that the sample is not of terrestrial origin, but instead crystallised on the Moon, however, that would require conditions never before inferred from lunar samples, researchers said.
It would require the sample to have formed at tremendous depths, in the lunar mantle, where very different rock compositions are anticipated, they said.
The simplest interpretation is that the sample came from Earth, according to researchers.
The rock crystallised about 20 kilometres beneath Earth’s surface 4.0 to 4.1 billion years ago.
It was then excavated by one or more large impact events and launched into lunar space.
Previous work by the team showed that impacting asteroids at that time were producing craters thousands of kilometers in diameter on Earth, sufficiently large to bring material from those depths to the surface, researchers said.
Once the sample reached the lunar surface, it was affected by several other impact events, one of which partially melted it 3.9 billion years ago, and which probably buried it beneath the surface.
The sample is, therefore, a relic of an intense period of bombardment that shaped the solar system during the first billion years.
After that period, the Moon was affected by smaller and less frequent impact events.

Apple launches iPhone 15 series, India price, features, availability
The iPhone 15 series will be available in India from September 22 but iPhone lovers can also pre-order, starting from September 15 onwards.
Apple launched its most anticipated iPhone 15 series, including the iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max during the Wonderlust event globally on September 12 night.
The iPhone 15 series will be available in India from September 22 but iPhone lovers can also pre-order, starting from September 15 onwards.
People can buy a new iPhone 15 or upgrade it to the old one. There are five colours available for the people.
According to reports, Apple has been manufacturing the iPhone 15 series in India and China. Apple has moved 7% of its iPhone production to India. Previously, India was not making the newest models. The Centre’s production-linked incentive (PLI) scheme for smartphones played a part in Apple moving its production to India.
The new iPhone 15 has been launched with the same starting price as its prototype, the iPhone 14. The 128GB variant is priced at Rs 79,900, while the 256GB variant costs Rs 89,900. For people who need more storage, the 512GB variant is available for Rs 1,09,900.
This latest iPhone series puffs a 6.1-inch display and comes in five different colours which are pink, yellow, green, blue, and black. While the design remains the same as the previous models, the iPhone 15 features a dynamic island notch instead of the usual notch, which was highly popular among the iPhone 14 Pro phones.
The camera part of the iPhone series has undergone significant upgrades, the new iPhone 15, with an enhanced 48-megapixel primary sensor replaces the 12-megapixel dual camera system which was available in the previous iPhone 14. This significant improvement promises better low-light photography and portrait shots.
The tech giant announced that the iPhone 15 has an all-day battery life, making it more convenient for users to go about their daily activities without worrying about their phone’s battery.
The iPhone 15 Pro models feature a lighter body and thinner bezels. The new AirPods Pro with USB-C charging case will support Lossless Audio with Apple Vision Pro.
Additionally, the iPhone 15 is powered by Apple’s A16 bionic processor, an upgrade from the A15 bionic chipset used in the previous iPhone 14 and iPhone 14 Plus models. The Pro models had the faster and better A16 chip, but now this feature is available in all iPhone 15 models.
The USB-C port on the standard iPhone 15 and iPhone 15 Plus remain limited to lightning speeds up to 480 Mbps. The iPhone 15 Pro and iPhone 15 Pro Max support USB 3 speeds up to 10 Gbps. People will need to buy a separate 1-meter Thunderbolt 4 Pro cable for Rs 5,724 or Rs 10,701 for the 1.8-meter cable to support faster speeds.
The dynamic island notch feature, which can adjust its size according to notifications, was widely discussed before the launch of the iPhone 15. This unique feature can now be available in all models of the phone.
Another important feature of the iPhone 15 is the shift to the USB Type C charging port. Apple has abandoned the lightning port in favour of the more commonly used USB Type C charging port. This means, there is no longer a need for a special iPhone charging cable to be carried around everywhere you go.
