About 5500, and counting… (see https://en.wikipedia.org/wiki/Lists_of_exoplanets) Planet Earth — Mother Gaia — provides everything needed by any form of planetaryContinue reading “499 Earth rotations to slow down”
Those stable icy hats that our planet used to have at her poles are gone. This has consequences.
Pale Blue Dot Revisited (2020) – Image credits NASA/JPL-Caltech I am in this picture. If you are at least 32 years old, you are in this picture as well. That tiny pale blue dot is planet Earth: it’s us. “The Earth is a very small stage in a vast cosmic arena. Think of the riversContinue reading “Pale Blue Dot, 32 years later”
There is one big tear on planet Earth, on the land humans call “Pakistan” these days, on the land with most glaciers after the poles, there is one big tear that space travellers could see.
We (as a planet) just made it to another aphelion. The cosmic advice for today is: take it slowly, enjoy those 500 m/s less than average orbital speed.
Good morning from the Vanguard of Climate Collapse in the rich part of the world: the Iberian Peninsula. This post was written as we were just coming out of a heat wave about ten days long: a heat wave that happened even before the solstice, which, I remember, marks the time of the year whenContinue reading “On heat waves and new emotions”
🇧🇷 🇪🇸 🇮🇹 This is home. As seen from Mars, after sunset. There is a little rover with a camera on Mars — humans sent it, and it took this photograph of all of us, 160 millions kilometers away. We all are the “evening star” in someone else’s sky. We all are just a tiny tinyContinue reading “Cosmic Home”
Mosaic of four different terrestrial point of view of the Milky Way galaxy: a cosmic ring made by photographer Alvin Wu.
🇪🇸 🇧🇷 🇮🇹 “Little” Cosmic Eyes: the difference a century of human advance can make. The barred spiral galaxy NGC 1398 as seen from Earth: today (ESO telescopes, photo on the left) and about 100 years ago (Telescope of the Palomar Observatory, photo on the right). The photons arriving on Earth are the same; weContinue reading “Cosmic eyes”
