Voyager hits a 'Wall of Fire': NASA probe finds a furnace at the edge of the solar system
Voyager 1 has detected a shell of superheated plasma far beyond Pluto—offering a direct look at where the Sun's influence ends and interstellar space begins. From nearly 24 billion kilometres away, NASA's ageing Voyager 1 has sent back a signal confirming one of the most extreme discoveries yet: a narrow region near the heliopause where plasma has been heated to an astonishing 30,000 to 50,000 Kelvin. This marks the latest in a string of insights from the 48-year-old spacecraft. The heliopause, which defines the outer edge of the Sun's protective bubble known as the heliosphere, is where solar wind slams into material from interstellar space. It's not a wall in the traditional sense—but data show a sharp, localised zone of extreme discovery began with a spike in temperature data—despite the fact that Voyager 1's original plasma detector had failed years two other instruments still running—one monitoring cosmic ray hits, the other measuring the local magnetic field—spotted the clues.

Kelvin Miranda channels confidence in new magazine cover
Kelvin Miranda is the featured artist on Rank Magazine's second "The Hot Damn!" issue. In his magazine covers, the Sparkle star oozed confidence while looking bold in three different outfits that flaunt his toned body. "Young actor Kelvin Miranda is taking on a role carved out of a well-protected material perched high atop the upper echelon of Philippine pop culture and entertainment," Rank Magazine wrote, referring to his portrayal of Adamus in "Sang'gre." "Off the pages of his next big career-making move, he may have been tasked to behold the gem of the element of water, but seeing him ride the current, a surge, even, of recent and upcoming roles on film, television, and even streaming, it goes without saying that Miranda is a man on fire." In his full cover story, Kelvin will talk about his acting evolution and his journey to self. Kelvin is starring in "Sang'gre" alongside Bianca Umali, Faith Da Silva, and Angel Guardian. It is the spinoff of the hit Kapuso fantasy series "Encantadia." "Sang'gre" airs on GMA Network from Mondays to Fridays at 8 p.m. after "24 Oras." You can also watch it online via the Kapuso Stream on YouTube. —Carby Rose Basina/MGP, GMA Integrated News

Woke-obsessed BBC would rather hand itself in to cops than air Clarkson's Farm – and that's why terrestrial TV is dying
APPROACHING four hours into the new Clarkson's Farm and not one animal had kicked or butted Jeremy in the nuts. A glaring sin of omission as far as most viewers were probably concerned. 5 Clarkson's Farm remains the best thing on TV and one of those incredibly rare shows that can make you smile just through the simple act of pressing 'play' Credit: Prime Video 5 BBC tried to copy Clarkson's Farm with shows like Kelvin's Big Farming Adventure, but has not come close to recreating the magic Credit: ITV Because, in terms of livestock, I think a bull was the only creature who hadn't poleaxed Clarkson during...

Kelvin Miranda spotted enjoying street food in QC
Kelvin Miranda was spotted at a street food cart in Quezon City on Wednesday! In a video, the Sparkle star could be seen buying squid balls and kikiam, and even taking over in serving street food to kids. He also engaged in cute conversations with the kids, asking them random questions. Kelvin is set to star in 'Sang'gre' as Adamus, the new keeper of the Brilyante ng Tubig. He will be joined by Faith Da Silva, Angel Guardian and Bianca Umali as the new keepers of Brilyante ng Apoy, Hangin and Lupa. The cast of "Sang'gre" also includes Glaiza De Castro, Sanya Lopez, Rocco Nacino, Ruru Madrid, Kylie Padilla, who will reprise their roles from "Encantadia." 'Sang'gre' will premiere on June 16 on GMA Prime. —JCB, GMA Integrated News
