Even in darkness, we glow. In this image of Earth taken by the Artemis II crew, we can see the electric lights of human activity. In the lower right, sunlight illuminates the limb of the planet.

New eyes on the universe 👀 #OTD in 2002, Hubble's Servicing Mission 3B launched. Astronauts installed a new instrument, the Advanced Camera for Surveys, that increased Hubble's scientific abilities 10-fold: go.nasa.gov/4tV0wBL

🚨: Astronomers have discovered the largest reservoir of water in the known universe — holding an astonishing 140 trillion times more water than all of Earth's oceans combined. Located 12 billion light-years away, this mind-bending find reshapes what we know about the role of water in the cosmos.

#Linux Secure by Design 🔒🐧🦥
Mr Ash@ash_twtz

Everyone says “Linux is secure and viruses don’t attack it easily” But why is that actually true? Very few people know the real reasons: 1. Linux user permissions are strict by design In Linux, normal users don’t have admin (root) access by default. Malware can’t install system-level files unless it explicitly gets root permission - which usually requires your password. No silent installs. 2. Software comes from trusted repositories Unlike Windows/macOS where people download random .exe files, Linux users install apps from official, cryptographically signed repositories. This massively reduces the chance of installing infected software. 3. Open-source = constant inspection Linux is open-source. Thousands of developers worldwide continuously inspect, audit, and improve the code. If a vulnerability appears, it’s often found and patched quickly - sometimes within hours. 4. No single point of failure Linux isn’t one OS - it’s hundreds of distributions (Ubuntu, Fedora, Arch, etc.). A virus written for one distro often won’t work on another. Malware authors hate fragmentation. 5. Kernel-level security features Linux uses advanced protections like: • SELinux / AppArmor (mandatory access control) • Address Space Layout Randomization (ASLR) • Secure memory handling Even if malware runs, its damage is heavily restricted. 6. Fewer users = lower incentive Linux dominates servers, not desktops. Hackers usually target platforms with maximum users for maximum profit. Desktop Linux simply isn’t the most lucrative target. 7. Fast updates, no forced delays Linux updates are lightweight, frequent, and optional - but encouraged. Vulnerabilities stay open for less time. 8. Command-line transparency Most system-level actions are visible. Nothing hides behind flashy installers. Suspicious behavior is easier to detect for experienced users. Conclusion: Linux isn’t “virus-proof” - nothing is. But its architecture, permissions model, open-source nature, and security-first design make it far harder to attack than most operating systems.
