CRA PERSPECTIVE • INTERSTELLAR SCIENCE Travel Time to Proxima Centauri b How Long to Reach the Nearest Exoplanet? 4.24 LIGHT-YEARS • 40 TRILLION KM • ONE DESTINATION An educational exploration of distance, speed, propulsion and the reality of interstellar travel. The Nearest Exoplanet Is Closer Than You Think — And Farther Than You Can Imagine Proxima Centauri b is the closest known exoplanet to Earth. It orbits a small red dwarf star in the Alpha Centauri system, just 4.24 light-years away. That sounds close in cosmic terms. But 4.24 light-years is roughly 40 trillion kilometres — a distance so vast that our fastest spacecraft would take thousands of years to cover it. This framework breaks down the journey by speed, from current technology to theoretical propulsion, and asks the central question: “How long would it actually take to get there?” The Four Pillars of Interstellar Travel ๐ DISTANCE 4.24 light-years ≈ ...
๐ฏ️ National Amnesty International Day – 28th May
Every year on 28th May, the world recognizes National Amnesty International Day (observed primarily in the United States) — a day dedicated to honouring the founding of Amnesty International (AI), one of the world's largest and most influential human rights organizations. The day celebrates AI's mission to protect human rights, free prisoners of conscience, abolish torture, and defend the dignity of all people.
Amnesty International was founded in 1961 by British lawyer Peter Benenson, after he read about two Portuguese students imprisoned for raising a toast to freedom. His article "The Forgotten Prisoners" (May 28, 1961) sparked a global movement. The organization has since grown to over 10 million members and supporters in more than 150 countries.

- ๐ Article 1 — All human beings are born free and equal in dignity and rights.

๐จ Art & Human Rights
Amnesty International has used art to advocate for human rights: poster campaigns (famous designs by artists like Keith Haring), photography exhibits documenting abuses, and concerts (Human Rights Now! tour with Bruce Springsteen, Sting, Peter Gabriel, 1988). Art humanizes statistics and moves people to action.
๐ฏ️ The Amnesty Candle
The symbol of Amnesty International is a barbed wire wrapped around a candle. The candle represents hope, light, and human dignity. The barbed wire represents oppression, prisons, and torture. The symbol appears on AI's logo and is used during vigils.
๐งญ A Message of Justice
On this 28th May, we honour Amnesty International — an organization that began with one man's outrage and grew into a global movement. Every letter written, every vigil lit, every voice raised has helped free prisoners of conscience, expose torture, and advance human dignity. But the work is not done. As long as one person is imprisoned for their beliefs, tortured, or silenced — Amnesty's work continues. This day is a reminder: human rights are not gifts given by governments. They are inherent to every person. Defend them.
๐ฏ️ It is better to light a candle than to curse the darkness. ๐ฏ️
