🪐 Freezing, arid and lifeless, the dusty Jezero crater on Mars is an inhospitable desert.

Yet, 3.7 billion years ago it was full of water and could have harboured life, scientists believe

Thread 🧵

🛰️The first analysis of images from Nasa’s Perseverance rover show the Jezero crater was once a huge 21-mile wide lake, which was fed by a river, and which suffered flash flooding

🦠However, researchers are most excited by the discovery of layers of fine-grained clay and mudstones at the site, because they could preserve traces of ancient life

Prof Sanjeev Gupta said: “We're not expecting to find fossils, but we could find evidence of microbial life."

🗣️“I think finding life is entirely likely. It would seem surprising that life only formed on Earth and these are definitely the right rocks to look for it.”
Zoomed images taken by Perseverance of the cliffs surrounding the crater show sloping rock beds sandwiched between horizontal layers that indicate rocky deposits from an ancient river

🌞The team says it suggests that there was steady water flow, consistent with a warm and humid Martian climate 3.7 billion years ago

🌄“If you look at these images, you’re basically staring at this epic desert landscape" said Benjamin Weiss, professor of planetary sciences in MIT’s Department of Earth, Atmospheric and Planetary Sciences

🌊The lake was thought to be tens of feet deep

Boulders weighing several tons, were found to have come from outside the crater, and were probably part of the original bedrock.

💧The floods required to move the boulders were likely to have raged at 20 miles an hour
🌏As well as providing more details about Mars, sampling the boulders could give important clues about Earth’s early geology which has since been destroyed by tectonic activity

⚫ Millennial mafia members in New York have been accused by veteran mobsters of going soft, @nickallen789 reports.

They’re obsessed with their phones and using text messages rather than fists to intimidate victims

Thread 🧵
telegraph.co.uk/news/2021/10/0…
The new generation of mafia soldiers are said to be less brutal and less versed in traditional in-person tactics.

➡️One alleged gangster sent his victim, a union official, a message saying: "Hey, this is the 2nd text, there isn't going to be a 3rd"
The extent to which social media has now infiltrated the crime world was evident in the recent case of a fugitive mafia suspect.

His son pictured him in a swimming pool in Florida and taunted the FBI by posting it on Twitter, along with a rat emoji 🐀

🇨🇳A sudden surge of Chinese warplanes into Taiwan’s air defence zone has raised alarm about whether the drums of war are beating louder across the Taiwan Strait.

How worried should we be?

Thread 🧵
telegraph.co.uk/world-news/202…
🛫A record-breaking 56 Chinese warplanes flew close to the island’s airspace on Monday, following 93 similar flights over the weekend.

The latest mission included 12 nuclear-capable H-6 bombers in the vicinity of the uninhabited Pratas islands claimed by both Taiwan and China
So, what is China up to?

🇹🇼Taiwan acts like any other nation with its own democratic government and military but China’s ruling Communist party claims the island of 24 million as its own territory even though it has never ruled there

@Telegraph's unannounced visit to the government building now in the hands of the Taliban was a relaxed affair, @benfarmerDT writes...
