The spacecraft landed on the unexplored south pole of the moon on Wednesday evening, days after Russia's Luna-25 failed, making India the first country to achieve this feat.

Under a landmark EU law, digital giants will be forced to more aggressively police content online to protect users, especially against hate speech and disinformation.

The crash comes almost a year and a half into Russia's Ukraine offensive that has seen Moscow isolated, with punishing sanctions that have affected its space industry. 

Though the surface of Mars is now an arid desert, billions of years ago rivers and vast lakes are thought to have stretched across its surface.

The Russian lunar mission, the first since 1976, is racing against India, which launched its Chandrayaan-3 lunar lander last month, and more broadly with the United States and China, both of which have advanced lunar exploration programs targeting the lunar south pole.

Launched in 1977 to explore the outer planets and serve as a beacon of humanity to the wider universe, it is currently more than 12.3 billion miles (19.9 billion kilometers) from our planet, well beyond the solar system.

The star-filled snapshots were taken during the space telescope's commissioning -- a phase during which its powerful instruments are finely calibrated -- and therefore not representative of its full potential.

The project was first reported by The New York Times, which is working with The Washington Post and The Wall Street Journal in testing the new product.

Founded in 2006, Twitter takes its name from a play on the sound of birds chattering, and it has used avian branding since its early days, when the company bought a stock symbol of a light blue bird for $15, according to the design website Creative Bloq. 

Arizona researchers have deployed a robot that can breathe, shiver and sweat to answer the burning questions of what happens to the body when a human gets heatstroke.

Webb, the most powerful observatory in orbit, was launched in December 2021 from French Guiana, on a million mile (1.6 million kilometer) voyage to a region called the second Lagrange point.

While ChatGPT took two months to hit the 100 million user mark and video-sharing app TikTok took nine months, Instagram itself took two and a half years to reach that mark after its 2010 launch.

This strange world, which is more than 260 light years from Earth, reflects 80 percent of the light from its host star, according to new observations from Europe's exoplanet-probing Cheops space telescope. 

That is the conclusion of scientists whose findings are offered as proof that rapid expansion of human appetites and activity so radically altered natural systems as to tip Earth into a new geological epoch called the Anthropocene, or the "era of humans".

Threads is a text-based sidekick of Instagram, the image-heavy social network that Facebook bought more than a decade ago and became the world's most popular app for photo sharing.

"In terms of where Tesla is at this stage, I think we are very close to achieving full self-driving without human supervision," Musk said via video link at the opening ceremony of an artificial intelligence conference in Shanghai.

Threads is the biggest challenger yet to Elon Musk-owned Twitter, which has seen a series of potential competitors emerge but not yet replace one of social media's most iconic companies, despite its epic struggles.

The Online News Act, adopted by parliament last month, requires digital giants like Google and Meta to make commercial deals to compensate Canadian news outlets when users access articles through their products, or face binding arbitration.

Zuckerberg's Meta group, which owns Facebook, has listed a new app in stores as "Threads, an Instagram app", available for pre-order in the United States, with a message saying it is "expected" this Thursday.

Einstein's theory of relativity predicts that because space is expanding, "we should see the distant universe run in slow motion," said Geraint Lewis, an astrophysicist at the University of Sydney and the lead author of a new study.

The social media firm, bought by billionaire Elon Musk last year, has been thrashing around for ways to make a profit, cutting staff and ramping up its paid-for subscriptions.

The mini rotorcraft, which hitched a ride to the Red Planet with the Perseverance rover in early 2021, has already survived well beyond its initial 30-day mission to prove the feasibility of its technology in five test flights.

Verified accounts were initially limited to reading 6,000 posts a day, Musk said, adding that unverified accounts will be limited to 600 posts a day with new unverified accounts limited to 300.

The launch is planned from Cape Canaveral in Florida at 11:12 am local time (1512 GMT) on a Falcon 9 rocket of the US company SpaceX.

The Online News Act became law last week, aiming to support a struggling Canadian news sector that has seen hundreds of publications close in the last decade.

The breakthrough -- made by hundreds of scientists using radio telescopes in North America, Europe, China, India and Australia after years of work -- was hailed as a major milestone that opens a new window into the universe.

But what are these disaster scenarios and how are machines supposed to wipe out humanity?

The remains of the Titanic rest on the seabed in the North Atlantic at a depth of some 3,800 meters.

The finding was based on a review of data collected by NASA's Cassini probe, and was published Wednesday in the prestigious journal Nature.

"It was a demo that John (Lennon) had, and that we worked on, and we just finished it up," said McCartney, who turns 81 next week.
