Looking at the current Navier–Stokes story, Sunil Mukhi’s point feels especially relevant right now.
"But asking the question, what is the question which we would like to understand?
That is the human contribution and I believe that one will last into the future."
The impressive part is not just that AI can now push through an enormous calculation. It’s that humans decided this was a question worth spending decades trying to answer in the first place.
AI may increasingly handle the calculation. But deciding which questions are worth asking may remain the most human part of science.

According to NASA, only ~5% of the universe is normal (baryonic) matter of which less than 1% is luminous.
The remaining ~95% is dark matter and dark energy, detectable only through their gravitational effects.
This picture is beautiful but misleading, since it only shows about 0.5% of the cosmic density. The other 99.5% of the universe is invisible.

The Ulysses solar probe passed over the Sun’s south pole, collecting data on solar wind and magnetic fields from a vantage no Earth-orbit mission can reach. Astronomy
A glimpse from the under-side of our star! Isn’t space science inspiring?

Happy National Space Day 🇮🇳
A day that marks our leap beyond Earth — when Chandrayaan-3 softly touched the Moon, proving that India can not only reach but explore worlds beyond.

🗓️ On this day, August 6, 1963 : Cosmonaut Valentina Tereshkova became the first woman to orbit Earth.
She wasn’t just first, she piloted solo.
A giant leap for representation in space. We never stop looking upward!

On this day, Science on the Moon had got an upgrade! 🧪
Apollo 15 lifted off July 26, 1971 with the first Lunar Rover, expanding how astronauts explored the Moon.
It transformed lunar exploration with surface mobility. Driving on the Moon became real!

🗓️ On this day, July 22, 1980, Vietnam’s Phạm Tuân flew aboard Soyuz 37, becoming the first person from outside the U.S. or USSR to go to space.
Space got a little more international.

ISRO has done phenomenal work in furthering science, from Chandrayaan to NISAR, but its public communication, outreach, and storytelling are seriously lacking.
ISRO doesn’t need hype but we need more transparency, & scientist spotlights.

Happy International Moon Day to everyone!
Ever wondered how the Moon looks from Earth's orbit?
Group Captain Shubhanshu Shukla has shared stunning images captured from the International Space Station.
Follow him on X @gagan_shux for more breathtaking views!
On this day in 1969 for the first time a human set foot on the moon. The moon that is 384,000 km away from us. The statement "It is a small step for a man but a giant leap for mankind" became etched in history as one of the most impactful. The achievement forever remains a powerful indication of the immense human potential.
Today as we are starting our human space flight journey with missions like Gaganyaan our eyes are also set on the same destination. The pictures I have taken are from the @iss except the last one that was taken from ground 2 years ago. We still have pictures of moon from Earth and near Earth orbit. What I would like to see is a picture of Earth from the moon clicked by one of you. Let's make it happen.
Picture 3- This is a snapshot from a video. I should have a better quality picture to post soon.

🚨 Space & science lovers!
Before galaxies formed, the universe went dark.
Then it lit up again.
Learn how scientists decode this era using radio astronomy and AI-powered simulations.
Hear it from Dr. Anshuman Acharya LIVE

Ever wondered how we study the universe before the first stars lit up?
Let’s break down the science behind the Epoch of Reionization and the 21-cm signal, before @Anshuman_1998 joins us on X Space this July 12.

10/ Anshuman's goal is to understand how the first light shaped the cosmos and his research looks at:
- The formation of the first stars and galaxies
- The conditions of intergalactic space
- The physics driving reionization
