Hi all, I’m taking a few weeks off (or may be intermittent, if things go well) from social media to address a left-eye issue. Have a lovely few weeks in the meantime. Cheers, Ashley

🌍 Ever wondered where Earth ends and space begins?

Let's take a quick journey up through the atmosphere:

✈️ Troposphere (0–11 km) — where we live, breathe, and where planes fly. 99% of all weather happens here. ☁️

🚀 Stratosphere (11–50 km) — home to the ozone layer that protects us from UV rays. Commercial jets cruise at its bottom edge.

🔥 Mesosphere (50–90 km) — the "meteor burner." This is where most shooting stars burn up. Also the coldest layer: down to -90°C! ❄️

🛸 Kármán line (100 km) — the official (unofficial) boundary of space. Above this line, aerodynamic lift becomes ineffective. Wings are useless — you need rockets.

Two cool facts:

🧠 1. The Kármán line is named after physicist Theodore von Kármán. But he actually proposed ~84 km. The 100 km mark was chosen as a nice, round number!

🛰️ 2. Even at 400 km (where the ISS orbits), the atmosphere isn't completely gone. The ISS loses about 2 km of altitude every month and needs regular boosts!

So next time you look up at the sky — space is just 100 km above your head. You could drive there in about an hour… if there was a vertical road. 🚗⬆️

Voyager 1 is about to make history 🚀✨⁠
⁠
In November 2026, NASA’s legendary probe is expected to become the first spacecraft ever to be one light-day away from Earth — so far that a signal from us would take a full 24 hours to reach it.⁠
⁠
Launched in 1977, Voyager 1 is still traveling through interstellar space nearly 50 years later. By around November 15, 2026, it should be about 16.1 billion miles (25.9 billion km) from Earth. 🌌⁠
⁠
Humanity really built something in the 1970s… and it’s still going. 🥲⁠
