Astronomers are on high alert after interstellar comet 3I/ATLAS streaked into the Solar System, unleashing a surge of energy and gas unlike anything seen before. Travelling at over 200,000 km/h, the alien object—the third confirmed visitor from another star system—has stunned scientists with its carbon dioxide-rich emissions, deep-space chemistry, and hyperbolic path that ensures it will never return. Observations from …

This July, astronomers were left reeling by an event unlike anything seen before: a gamma-ray burst (GRB) that repeated four times in a day, instead of lasting a few minutes as is usually the case. The JWST has examined the source of this event and a paper undergoing peer-review claims the total energy released probably exceeded anything previously witnessed, including …

Lauren Taylor Wolfe, the managing partner at Impactive Capital, says that the current wave of excitement around AI is a bubble that will eventually burst. In an interview with CNBC, she compared today’s AI craze to the dot-com boom of the late 1990s. “We are absolutely in an AI bubble now. It is going to burst. I don’t know when. …

Over the past year, a few AI startups have together accumulated nearly $1 trillion in valuations despite remaining unprofitable.

The central bank of the United Kingdom is worried about an AI bubble burst. “On a number of measures, equity market valuations appear stretched, particularly for technology companies focused on Artificial Intelligence (AI),” the bank’s financial policy committee said, according to a record of its latest meeting. “This, when combined with increasing concentration within market indices, leaves equity markets particularly …

The Washington Post notes AI’s “increasingly outsize role” in propping up America’s economic fortunes. “Last week, the United States reported that the economy expanded at a rate of 1.6 percent in the first half of the year, with most of that growth driven by AI spending. Without AI investment, growth would have been at about a third of that rate, …

IN A NUTSHELL 🌌 Scientists detect the heartbeat of a newborn magnetar within a gamma-ray burst, revealing new cosmic insights. 🚀 The discovery challenges the belief that gamma-ray bursts are solely powered by black holes. 🔍 Researchers identified a periodic signal that confirms some gamma-ray bursts are driven by newborn magnetars. 🌠 The findings open new avenues for understanding the …

The similarities are striking. Like the internet companies of two decades ago, AI firms today attract massive investments based on transformative potential rather than current profitability. Global corporate AI investment reached $252.3 billion in 2024, according to research from Stanford University, with the sector growing thirteenfold since 2014. Meanwhile, America’s biggest tech companies—Amazon, Google, Meta, and Microsoft—have pledged to spend …

IN A NUTSHELL 🌌 Astronomers discover a unique gamma-ray burst lasting nearly a full day, challenging existing theories. 🔭 Advanced telescopes like the Hubble Space Telescope confirm the burst originated outside the Milky Way. 🌀 The event may involve an intermediate-mass black hole, a rare cosmic object. 🔍 Researchers are focused on determining the exact location and energy output of …

Facebook Tweet Email Link Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary death of a star, or when it is shredded by a black hole. The observation of repeating bursts has never occurred before, given that …
