James Webb Spots Planets Forming Into Solar System in Real Time, Like an Organism's First Cells

futurism.com Unknown 2025-07-23 20:30:53

Astronomers have spotted a planetary system being conceived from the swirl of gas and dust surrounding a star — giving us an unprecedented, real-time look at how our solar system would've formed some 4.6 billion years ago. The findings, published as a study in the journal Nature, are the first time we're seeing such an early stage of planets being formed anywhere in the cosmos. "We've captured a direct glimpse of the hot region where rocky planets like Earth are born around young protostars,"

Key Home Energy Tax Credits End This Year. Act Quickly if You're Considering Solar Panels, Experts Say

A big federal tax credit for homeowners who get solar panels will end this year, meaning a window for significant savings on going solar is closing fast. The 30% credit has long been the biggest single incentive for residential solar panel adoption, and its expiration is a significant blow for what has been a fast-growing industry. For homeowners, its elimination significantly changes the calculus of whether solar panels make financial sense compared with paying utility electrical rates. "It's

Colossal Eruption Carves ‘Canyon of Fire’ Onto the Sun’s Surface

gizmodo.com Gayoung Lee 2025-07-29 04:10:22

On July 15, a solar filament erupted from the Sun’s upper left side, ejecting a powerful blast of plasma and magnetic fields into space. The resulting explosion was so massive that it seared a deep, fiery scar of hot plasma and debris onto the star’s visible surface. While filament eruptions aren’t uncommon, astronomers had already been watching an unusually large filament—cold, dense ribbons of gas suspended above the Sun’s surface—that they spotted days before the explosion.

Astronomers in Japan have spotted a distant object orbiting the Sun far beyond Neptune, pointing to an extraordinary event that took place during the earliest years of the solar system. Astronomers used the Subaru Telescope, perched atop a dormant volcano in Hawaii, to make the discovery. They observed a small object orbiting at a farthest distance of 252 AU from the Sun, in which one astronomical unit equals the average distance between the Sun and Earth.

Why recycling solar panels is harder than you might think

news.ycombinator.com Anurag Srivastava 2025-08-04 08:38:18

It’s hard work soaking up sunlight to generate clean electricity. After about 25 to 30 years, solar panels wear out. Over the years, heating and cooling cycles stress the materials. Small cracks develop, precipitation corrodes the frame and layers of materials can start to peel apart. In 2023, about 90% of old or faulty solar panels in the U.S. ended up in landfills. Millions of panels have been installed worldwide over the past few decades – and by about 2030, so many will be ready to retire t

China’s energy dominance in three charts

So while we all try to get our heads around what’s next for climate tech in the US and beyond, let’s look at just how dominant China is when it comes to clean energy, as documented in three charts. China is on an absolute tear installing wind and solar power. The country reached nearly 900 gigawatts of installed capacity for solar at the end of 2024, and the rapid pace of building has continued into this year.
