It is a very tempting fantasy, but we ought to be energy efficient. The present age is a mixed bag, to say the least. Corrupt, useless, and just plain evil politicians have existed for as long as we had politicians, but it feels that we are experiencing a surplus at
Failures of communications in the recent eclipse and how art came to the rescue… even in a practical way
ple of months, I have seen the image above several times, and I had several friends sending it to me. Completely fair, you do not write an astronomy book called Invisible Rainbows without becoming “the space rainbow person." Unfortunately, we are not seeing a rainbow here. And it'
I do not believe that UFOs are aliens, but I was expecting some weird lightning phenomena or maybe an experimental weapon testing. Not a poor paint job from NASA.
I am so excited to be able to take Invisible Rainbows on a book tour. We have many places on the cards, but waiting for confirmations. More links as they happen! Birmingham - July 22 Events - The Heath BookshopA friendly indie bookshop in Kings Heath, BirminghamThe Heath Bookshop Order the Book:
Issue 2 of the newsletter and its already a rant!
Join us in this unplanned video & audio diary as we go after the April 8 total solar eclipse in Mexico.
A brief timelapse of the conjunction of Venus and Jupiter on March 3, 2023, as they come into view in the London dusk. The two planets are less than one degree part in the sky. 🤩
I was asked on Twitter on behalf of a very curious four-year-old what was the fastest moon in the Solar System. And I need to admit that I was a bit stumped. Which moon moves the fastest around its planet? Well, the answer might surprise you. Or maybe not. My reasoning is that the bigger […]

Invisible Rainbows, by Alfredo CarpinetiToday has been a very frustrating day from the point of view of travel – apparently it’s too hot for trains to function – but at least that gave me time to read the book Invisible…In the DarkJuly 10, 2026 at 11:57 amSeeing Things in
On August 12, 2026, Iceland and Spain will experience a total eclipse of the Sun. I have been asked by a few people for advice and suggestions about glasses and locations for the eclipse, so here are a few things. Chasing The Black Sun If you know me, you'
Better writers and thinkers than me have been discussing the concept of institutional capture. This is a form of political corruption that involves placing ideologically motivated people in particular institutions to no longer act for the benefits of all but the specific interests of powerful people. We have seen it
As I write these words, I have just had confirmation from NASA that Voyager 1 will be 1 light-day from Earth on November 18 (already the International Day of LGBTQIA+ people in STEM—making it a very busy day for me!). I do love Voyager 1 and Voyager 2,
Where we muse about big discoveries about space and magnetism!
It was my book launch this week, and Invisible Rainbows is officially out! One of the audience questions (which I swear I did not plant) was about the famous Arthur C. Clark quote about alien life: "Two possibilities exist: either we are alone in the Universe or we are

During the last fortnight, I had a wonderful interview with Paolo Martino the project manager for the RAMSES mission. RAMSES stands for Rapid Apophis Mission for Space Safety, and when it comes to backronyms it is not too bad. It's a mission from the European Space Agency (ESA)
The Artemis II mission has been the focus of much space coverage in the last two weeks. For good reason, the first human mission to deep space in 54 years was a resounding success. The four astronauts (NASA’s astronauts Reid Wiseman, Victor Glover, and Christina Koch, and Canadian Space

What if the Universe around us is far richer than we can perceive? In Invisible Rainbows, astrophysicist and science journalist Dr Alfredo Carpineti reveals the extraordinary hidden universe beyond the limits of human vision and how we have learnt to harness it. The book comes out on May 21, and
