The #PaleBlueDot captures the fragility and beauty of our planet. Taken from billions of miles away, it shows #Earth as a tiny speck of light, suspended in the vast expanse of space. It is a humbling reminder of our place in the universe, and a call to cherish and protect our home.

Even in space, telescopes can’t escape photobombers | Nature
Light reflected from satellites pollutes the images taken by telescopes orbiting Earth, as well as those on the ground. Without mitigations, this will only get worse.

Today is December 3. On this date in 1616 mathematician John Wallis was born. He contributed to the invention of calculus. He also invented and introduced the symbol ∞ for infinity.

Cheap calculators often use BCD (binary-coded decimal) rather than IEEE floating point. It’s likely holding 9999998 in the register and calculating the next digit as 9 (resulting in ...89), but the display driver truncates the buffer before the rounding logic triggers.
I don’t know how these simple calculators work. My son has noticed if he repeatedly square roots, say, 0.7734 it converges on 0.9999998 but then just sits there. Why does it think √0.9999998=0.9999998?

Happy 10th launchaversary!
Happy 10th launch anniversary, LISA Pathfinder! 🥳
For the first time ever, this mission tested in space the technology needed to detect gravitational waves, which paved the way to LISA 🤜 🤛
Planned to launch in 2035, LISA will be first gravitational wave detector in space 👉 esa.int/lisa

Let's dive into the dusty central region of the Milky Way!
There, a swarm of stars orbits an invisible, supermassive #BlackHole. As we get closer to it, we see these stars, as observed by the VLT (in 2019) and VLTI (mid-2021).

We knew from prior analyses that a distant asteroid sampled in 2020 carried all but one of the molecules needed to kick-start life, and researchers have just found the missing ingredient: sugar

Our #MarsExpress spots a strange shape on Mars, formed as a space rock collided with the planet's dusty surface.
It's known as a 'butterfly crater' but we see a walnut, an insect, the Eye of Sauron, or perhaps a moth... what do you think?

There’s something about QM and the number 25… 🤔 A faint echo in the math, like a door that only opens every twenty-fifth try. No one agrees what’s behind it...only that the equations flinch, just a little, when you look too closely. 👀
