After nearly half a century in deep space, every ping from Voyager 1 is a bonus

news.ycombinator.com Richard Speed 2025-10-11 18:49:14

It is almost half a century since Voyager 1 was launched from Cape Canaveral in Florida on a mission to study Jupiter, Saturn, and the atmosphere of Titan. It continues to send data back to Earth. Although engineers reckon that the aging spacecraft might survive well into the 2030s before eventually passing out of range of the Deep Space Network, the spacecraft's cosmic ray subsystem was switched off in 2025. More of the probe's instruments are earmarked for termination as engineers eke out Voy

Scientists Say Black Holes Could Form Inside Planets, Leading to Absolute Catastrophe

futurism.com Unknown 2025-10-27 04:22:37

New fear unlocked: spontaneous black hole implosion. Fresh research predicts that planets may be able to accumulate enough dark matter to suddenly form a black hole at their core. As the intruder grows, catastrophe unfolds: it would then devour the world from the inside out, becoming a black hole with the same mass as its unfortunate meal. The findings, published as a study in the journal Physical Review D, are terrifying to contemplate. The intent, however, wasn't to haunt our dreams but to d

Fresh off the excitement of the Perseids meteor shower is a chance to see six planets lined up in the sky at once. These events, colloquially known as planet parades, occur occasionally with the most recent one in February showing off all seven planets in our solar system at once. This one features six of our closest celestial neighbors. The main event started on Tuesday and you should still be able to see them through Thursday or so. There won't be a repeat performance until October of 2028. T

Why We Migrated from Neon to PlanetScale

James Webb Finds Evidence of Free-Floating Planets So Large They Can Gather Their Own Planetary Systems

futurism.com Unknown 2025-12-01 12:30:04

So much for heliocentrism. An international team of astronomers using observations made with the James Webb Space Telescope have found evidence of massive planets out there that're capable of forming their own planetary systems — without a star. These planets would be the center of something like a mini version of our solar system where other, smaller planets revolve around it. But without the light of a star, these systems, if they exist, would go largely overlooked by our telescopes, lost to

This Star System Contains 5 Potentially Habitable Planets

wired.com Jorge Garay 2025-12-29 08:48:16

A team of astronomers from the University of Montreal has discovered a new potentially habitable exoplanet orbiting the red dwarf star L 98-59, 35 light-years from Earth. This discovery means there are now five confirmed planets in this solar system’s “temperate” or “habitable” zone, the region in a solar system where liquid water could exist on planets’ surfaces. The newly discovered planet, called “L 98-59 f,” managed to evade previous observations because it doesn’t pass between Earth and it

Uranus Leaks More Heat Than We Thought

gizmodo.com Gayoung Lee 2026-01-20 17:25:45

When Voyager 2 flew past Uranus in 1986, the spacecraft detected a surprisingly low level of internal heat from the planet. Since then, scientists believed Uranus to be the odd one out in our solar system’s family of giant planets—the others being Jupiter, Saturn, and Neptune—who all tend to emit more heat than they absorb from sunlight. Now, a new study suggests that scientists may have had the wrong idea about Voyager 2’s data: Uranus does have an internal heat source similar to its planetary

A Giant Planet and a Small Star Are Shaking Up Conventional Cosmological Theory

wired.com Ritsuko Kawai 2026-02-02 14:00:00

Many of the stars in the Milky Way galaxy are small, dim red dwarfs—stars much smaller than the sun in both size and mass. TOI-6894, located far away from Earth, is one of them. Astronomers previously thought a star like this could not have large planets circulating it, because its mass is only about 20 percent of the sun, meaning its planetary system—generated from materials surrounding the star—would not have contained enough mass to form a giant body like Saturn or Jupiter.

Webb Telescope Just Did Something It’s Never Done Before—and Astronomers Are Thrilled

Since it began its science operations in July 2022, the James Webb Space Telescope has been probing the atmospheres of alien planets to study their potential for habitability. For the first time, however, Webb has discovered its own exoplanet, finding a young system hidden in a swirling cloud of dust and debris. Webb has captured a previously unseen exoplanet, the lightest planet imaged so far—an accomplishment made possible by the space-based telescope’s advanced capabilities. The recent disco
