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. 🤩

Inside neutron stars, matter ends up in weird shapes known as nuclear pasta. And I've got a real recipe to make the same pasta for a quick homemade lunch!

In this new #ScienceFromHome video we talk about galaxies visible to the naked eye and what the Milky Way looks like from its largest satellite.

My friend Sacha started this great hashtag on twitter #MuseumfromHome and my first contributions was a little video about the cabinet containing some of Sally Ride's personal effects at the Smithsonian National Air & Space Museum in Washington D.C.

In this video, I briefly talk about the role Iceland has played and continues to play in the Space race.

We did a short video about the equatorial monument at Mitad del Mundo. Check it out!

My new video this week is about ice, aliens, and people who have too much time on their hands!

I’ve been asked a few times about powerful supermassive black holes, and one of my old articles has suddenly become popular again, getting a thousand views in June, so I think we are in a new zeitgeist of black hole interests. So, I’ve prepared a little video about an extremely powerful object known as RX J1532.9+3021

It’s #International Astronomy Day and Hubble has turned 27 this month! Let’s celebrate with some of its most breathtaking pictures!

An international team of astronomers has made a great discovery. A nearby exoplanetary system has seven Earth-size planets!

This documentary explores the tumultuous lives of galaxies with a focus on galaxy collision: the key mechanism in galaxy evolution.

A cool thing to do if you have leftover dry ice is to snuff out candles using just carbon dioxide. You put dry ice in a jar and let it sublimate. The carbon dioxide will remain in the jug, as the density of CO2 is around 1.98 kg/m3, making it denser than the average density.
