Why Hasn't Voyager Frozen Yet After Half a Century?

Voyager is out in the dark, so far from home that its faint radio whisper now takes almost a full day to reach us. The temperature out there sits near minus 454° F minus 270° C, only about 3 degrees above absolute zero, the coldest anything in the universe can ever get. By every instinct we have, nothing should be alive out there. And yet Voyager 1 is still awake, and it answers every time we call. The probe launched in 1977, back when a pocket calculator felt like the future, and has been flying for more than 45 years. In that time Voyager has crossed over 14 billion miles 23 billion km of almost pure emptiness, slipped past the outer edge of everything our sun controls, and is somehow keeping in touch. So how does a spacecraft older than most of the people watching this keep working in the coldest place we have ever reached, without simply freezing to the end? -- DISCUSSIONS & SOCIAL MEDIA Commercial Purposes: [email protected] Tik Tok:   / insanecuriosity   Reddit:   / insanecuriosity   Instagram:   / insanecuriositythereal   Twitter:   / insanecurio   Facebook:   / insanecuriosity   Linkedin:   / insane-curiosity-46b928277   Our Website: https://insanecuriosity.com/ -- Credits: Ron Miller, Mark A.
