RIP Bashir Badr. 1935-2026. Urdu language lost a sparkle.

A very caring human being. So many Canadian and Pakistan charities lost their champion today. A very sad day.

[Mayor Frank Scarpitti @frankscarpitti]

It is with great sadness that I share the news of the passing of Khalid Usman.

Today our community lost a giant.

Today so many of us lost a great friend.

Khalid was a legend here at home and in Pakistan.

Some of my favorite stanzas by Faiz 🧵

[Saad Ahmed Mirza @mzsaad]

کبھی تو وصل کنارے لگے گی شامِ فراق, امید ہو کہ نہ ہو، انتظار رہتا ہے
چلو کوچۂ دانا میں دل سے مل آئیں, وہیں کہیں یہ غریبُ الدیار رہتا ہے

[Massimo @Rainmaker1973]

The Game of Thrones theme was composed by Ramin Djawadi, who is of Iranian descent.

Hearing this melody played with Persian instruments and the daf drum is absolutely beautiful.

BTW, The Nancy Grace Roman Space Telescope, scheduled for launch in September 2026, will make the Sun–Earth L2 its new home.

There are 5 invisible “sweet spots” in space where gravity perfectly balances.

They are called Lagrange Points.

And some of humanity’s most powerful spacecraft live there. 🧵👇

[Saad Ahmed Mirza @mzsaad]

Lagrange Points aren’t “zero gravity.”

They’re perfect balances of gravity + orbital motion.

Not absence of force.
Alignment of forces.

That’s a powerful idea — in physics and beyond. 🚀

Hidden deep in Venezuela’s jungle, Salto Duruhuaya is a striking waterfall known for curtain-like cascade over granite rock.

It drops over 100 meters down a granite rock face, often accessed via boat and jungle trekking.

Nanga Parbat known as 'King of the Mountains', is the ninth-highest mountain on Earth, its summit at 8,126 m (26,660 ft) above sea level. Lying southeast of the northernmost bend of the Indus River in the Gilgit-Baltistan region of Pakistan.

Cold Desert, Skardu, Pakistan. Have you heard about such a desert before? Pakistan never ceases to emaze me!... 😲

[The Earth @hikingtheglobe0]

The Highest Cold Desert In The World.

This is #Pakistan. What a chance to experience it first hand ! 🙏🙏🇵🇰

Neil deGrasse Tyson breaks down the mind-blowing journey of Earth through space—from spinning at 800 mph to orbiting the Sun, wobbling on its axis, and moving through the galaxy.

In just minutes, he reveals how multiple cosmic motions combine into a stunning, ever-changing path through the universe.

A proud moment seeing my daughter Ayzel’s name fly aboard Orion with NASA Artemis. Thank you @NASA. Praying for a safe journey and return for all astronauts. Godspeed. 🚀

[NASA Artemis @NASAArtemis]

Did you send your name aboard Artemis II???

If you did, then your name is literally in my pocket!! And every time you see me floating around the Orion spacecraft — that’s where your name is! With ME!

Don’t worry — I’ve kept your names safe as I’ve flown around the Moon 🫡 -Rise

If one image could make our beautiful blue world seem tiny and humbling, it would be this one.

[BBC World Service @bbcworldservice]

Why do we know so little about the Indus Valley people - a sophisticated civilisation believed to be bigger than both ancient Egypt and ancient Mesopotamia that existed for thousands of years.

🎧 How long will traces of our civilisation last? https://t.co/DWXtzMiXTs

[Saad Ahmed Mirza @mzsaad]

As Orion spacecraft moves away from Earth, gravity slows it - like a thrown ball upwards - but it never hits zero speed. Instead it stays in orbit. Without the Moon, it would follow an elliptical path, slow at the farthest point, then speed back up. #artemis #space #nasa

[Saad Ahmed Mirza @mzsaad]

We are still using the equations developed by a 23-year-old Isaac Newton in the 1660s - during a plague lockdown, when Cambridge University was closed.
Today, they guide spacecraft with incredible precision to the Moon… and back. #artemis #nasa #newton

[Michael Antonelli @BullandBaird]

Imagine the math required to make this guess and aim 4 people at a point in space

[Saad Ahmed Mirza @mzsaad]

@NASA @NASAArtemis I heard carbon dioxide disposal would be tested in the Orion. Question what did we do during Apollo days?
