In November 2026, a historic milestone awaits humanity's Voyager 1. The legendary probe will reach the "one light-day" mark, meaning it will be so distant that communication requires a 48-hour round trip!

"I was completely overwhelmed by the beauty of it all, to the point of forgetting everything around me! A sky of absolute purity, free from artificial light.”
This is how astrophotographer Julien Looten remembers the night he captured this extraordinary view of our VLT at Cerro Paranal, #Chile
Wondering what all those cosmic objects and phenomena in the image are?

You need patience in science. Our paper proposing to image the shadow of a black hole was published 26 years ago. It has now gained over 1000 citations in the scientific literature (according to ADS), which is a lot.
At the time of writing it was rejected by Nature and Science and it didn't get a huge amount of citations initially, but then it continuously increased (shown are the citations per year below).

It's Stephen Hawking's birthday. The occasion to share this fantastic video he produced as part of his Genius documentatry series. Hawking elaborates on our place in the Universe, including our membership to the Laniakea supercluster of galaxies that we discovered back in 2014.

Fun fact, the planet #Earth is not where it was a year ago, when 2025 started.
Yes, the Earth orbits our local star. However, our local star orbits the #MilkyWay and has moved about 6.3 billion kilometres around the Milky Way since 2025 started. As our star moved about 6.3 billion kilometres, so did the Earth.
Oh, and of course, the Milky Way is also moved about 20.2 billion kilometres since 2025 started.
Now someone with real mathematical skills will draw vectors and can precisely tell you how far the Earth moved in the last year, but it is going to be *around* 26-27 billion kilometres since 2025 started.
As you are on the Earth (or, very unlikely, you are orbiting the Earth) you have also travelled about 26-27 billion kilometres since 2025 started.
Remember, as Douglas Adam’s observed: Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is.

Hello Fedifriends!
Can anyone recommend an astronomy app?
There are many and I have many of them but I only want to invest in the "premium" service for once single app and I can't decide...
Stellarium mobile?
Sky tonight?
Star walk2?
A completely different one?
I want help recognizing what I see in the sky, data on specific stars and planets... But the AR description of Star walk 2 advanced features sound amazing too... Are they worth it?
