NASA’s James Webb Space Telescope uncovers ‘boiling ocean’ exoplanet – could it harbour life?

[ad_1] In a groundbreaking discovery, NASA's James Webb Space Telescope (JWST) has revealed intriguing details about a distant exoplanet, sparking a debate among scientists about its potential habitability. The exoplanet, known as TOI-270 d, lies approximately 70 light-years away and boasts twice the radius of Earth.Observations from the James Webb Space Telescope exposed the presence of water vapour, methane, and carbon dioxide in the exoplanet's atmosphere, suggesting a composition consistent with a colossal water world. Researchers from the University of Cambridge propose that an entire surface ocean, potentially reaching temperatures exceeding 100 degrees Celsius, envelops TOI-270 d. However, they caution against envisioning this as an inviting seascape, emphasizing the extreme cond...

ET Life? NASA discovers potential extraterrestrial oceans on 17 far-off exoplanets

[ad_1] In a groundbreaking study, NASA has unveiled a revelation that expands the search for extraterrestrial life. Researchers have identified 17 exoplanets positioned beyond our solar system that might boast subsurface oceans beneath their icy exteriors. The intriguing aspect lies in the possibility of periodic eruptions, resembling geysers, breaking through the frozen crusts of these distant worlds. Subsurface OceansThe research, conducted by scientists at NASA's Goddard Space Flight Center, included a meticulous analysis of geyser activity on these exoplanets. Remarkably, two of these celestial bodies are within observational reach of telescopes, presenting an unprecedented opportunity to witness these icy eruptions. This discovery holds paramount significance as the subsurface ocea...

Carl Sagan detected life on Earth 30 years ago – here’s how his experiment is helping us search for alien species today

[ad_1] It's been 30 years since a group of scientists led by Carl Sagan found evidence for life on Earth using data from instruments on board the Nasa Galileo robotic spacecraft. Yes, you read that correctly.Among his many pearls of wisdom, Sagan was famous for saying that science is more than a body of knowledge – it is a way of thinking. In other words, how humans go about the business of discovering new knowledge is at least as important as the knowledge itself. In this vein, the study was an example of a “control experiment” – a critical part of the scientific method. This can involve asking whether a given study or method of analysis is capable of finding evidence for something we already know.

Wow! NASA finds building blocks of LIFE in Bennu Asteroid sample!

[ad_1] NASA has been making efforts to track and study asteroids to remove uncertainties about their close approaches with Earth and know about any potential impacts. Through its various advanced instruments, NASA revealed that a Potentially Hazardous Asteroid (PHA) called Bennu has a 1/2700 chance of impacting Earth between 2175 and 2195. In efforts to study this space rock, NASA launched the Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer (OSIRIS-REx) on September 8, 2016. The mission involved travelling to the asteroid, landing on its surface, collecting dust and rock samples, and returning them to Earth. The mission is now over as the OSIRIS-REx spacecraft recently released the sample container over Earth, after which it underwent a “nitroge...

It’s Done. The Future Is Battery-Powered Electric Cars

[ad_1] The rise of electric cars is staggering.Over the past decade, Teslas have gone from being the car of the uber rich to the car of the Uber driver. All of the major automakers are taking the plunge on EVs, which is driving down prices and expanding available options. Globally, this year will see more than 14 million electric cars sold, according to BloombergNEF, compared with just 700,000 in 2016. And some 23 countries have now passed a crucial EV tipping point — 5% of new-car sales — after which adoption picks up dramatically. In China, the biggest EV market, 38% of new-car sales were electric in August. “We're off to the races on EV adoption in China now,” says Colin McKerracher, head of Advanced Transport at BloombergNEF, on this week's episode of Zero. Despite the tacit consens...

AI chip crunch: startups vie for Nvidia’s vital component

[ad_1] The artificial intelligence revolution is fully underway, but soaring demand for its most crucial component has startups scratching their heads on how they can deliver on AI's promise.Generative AI's lifeblood is a book-sized semiconductor known as the graphics processing unit (GPU) -- built by one company, Nvidia. Nvidia's CEO and founder Jensen Huang made a wild bet years ago that the world would soon clamor for a powerful chip usually used for making video games, but that could build AI as well. No company working with the generative AI models that fuel today's frenzy can get off the ground without Nvidia's singular product: the latest model is the H100 and its accompanying software.That painful reality is one that Amazon, Intel, AMD and others are scrambling to fix with their...

Pragyan Rover sleep countdown: 1 day to go for ISRO to bring Chandrayan-3 mission to life at Shiv Shakti point

[ad_1] In a few hours, the Sun will rise on the Shiv Shakti point on the Moon. It's a big moment for the Indian Space Research Organisation (ISRO). They've been working tirelessly and now the countdown is on to to wake up Pragyan rover sleeping on the Moon for the last 15 days now. Will ISRO be able to disturb Pragyan Rover from its sleep to continue the Chandrayaan mission. If Pragyan Rover was strong enough to withstand the tough lunar night with temperatures of -200 degrees and wakes up, then it would be a miracle indeed. Know what ISRO plans as the reboot countdown is on. Know that just one day is left for Pragyan to be woken up as per ISRO schedule.The 'Reboot' PlanISRO scientists have a plan to give the lunar explorer a fresh start. They are going to try something like a "reboot" ...

Last ‘Super Blue Moon’ until 2037 rises tonight

[ad_1] Astronomy enthusiasts are in for a treat Wednesday night: a rare "super blue Moon" that won't be seen again for more than a decade.Supermoons occur when the Moon passes through its perigee, or the point that takes it closest to Earth during its elliptical orbit. This makes it look about 14 percent bigger compared to when it is at its furthest point, and a touch brighter. Full Moons are defined by the exact moment they are opposite the Sun, which will occur at 9:36 pm Eastern Time on August 30 (0136 GMT Thursday), according to NASA. The Virtual Telescope Project, hosted by Italian astronomer Gianluca Masi, will host a YouTube livestream beginning at 0336 GMT as it sets below the skyline of Rome.Despite the description, it won't actually be blue: the term "blue Moon" simply refers ...

Investors Are Happy to Pay Premium for Tech, But Not for AI

[ad_1] Investors on Wall Street and beyond are betting that the great tech rally of 2023 has staying power, even as they appear skeptical that the artificial-intelligence era will live up to the hype.Some 77% of the 514 respondents to the latest Markets Live Pulse survey are planning to either increase their exposure to technology stocks or keep it steady over the next six months. Meanwhile, less than 10% see a bubble in the sector bursting anytime soon. That bullishness has pushed the Nasdaq 100 to its best first half in history, ramping up market valuations and blindsiding pros on the Street. Yet while survey participants are likely riding the AI-fueled market melt-up thanks to their broad equity exposure, they aren't going all-in on the technology just yet. Half are disinclined to pa...
