Doing world building is one of the hardest things I have ever done in my entire life. You think of everything there is on Earth, and now you have to do the same thing but try and make it as original as possible. I have to ask myself questions like β€œwhat REALLY is a plant?”

Proud to have my paper published in the MNRAS journal earlier this year. We studied how the mass of the circumgalactic medium changes its physical properties in cosmological simulations. Thoroughly proud to have this work published! πŸ”­

On July 02, 2025, astronomers confirmed the discovery of Comet 3I/ATLAS, marking only the third time in recorded history that an interstellar object (ISO) has been identified passing through our Solar System. This follows the landmark discoveries of 1I/β€˜Oumuamua in 2017 and 2I/Borisov in 2019. πŸ§ͺ πŸ”­ πŸ‘©β€πŸ”¬

Tomorrow morning, instead of clouds covering the Sun, a partial solar eclipse will cover 30-50% of the Sun instead in the UK!

If anyone is in the Cardiff area and interested in seeing the eclipse, there will be an event held by Astronomy on Tap at Jacob's Antique Centre from 10am until 12pm!πŸ”­

For any astronomy lovers in the Cardiff area, there is an event at Porters pub I co-organise called Astronomy on Tap! This month's event is on the 20th from 6pm with free entry so if you've got an appetite for all things space, it might just be up your street! πŸ”­ (Photo credit: Porters Pub)

Planetary parade: Mercury falls into line for rare seven-planet alignment The seven will appear to form a straight line in the night sky in display that won’t be seen again until 2040

If you’re about this evening, it is the peak of the alignment of the planets! Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune are all visible tonight spanning the length of the sky. More info here: www.theguardian.com/science/2025... πŸ”­

I don’t think any bands songs have made me more motivated to work than Creed’s.

Well it finally happened.

As of last week, my PhD thesis has been finally accepted πŸ™ I'm so happy to see this work be published after so long. Onto the next thing now! πŸ”­

I'm starting fleshing out a board game idea I've had for a few years now. It's got many different mechanics in it so I'm looking for advice. #boardgame enthusiasts what are your favourite mechanics in board games and why? Also, what are your favourite board games?

Abundant ammonia and nitrogen-rich soluble organic matter in samples from asteroid (101955) Bennu - Nature Astronomy Rocks and dust from the asteroid Bennu contain some of the molecular building blocks of life on Earth, such as amino acids and nucleobases. They also carry ammonia that formed billions of years ago in...

The origins of life on Earth are somewhat of a mystery but the asteroid Bennu has recently been shown to contain many of the molecules present for life to form! This includes 14 amino acids, amines, carboxylic acids and more! πŸ”­

Quadrantid meteor shower to light up skies tonight - here's the best way to watch The Quadrantid meteor shower returns each year in January - but the position of the moon this year should increase visibility in the UK, the Royal Astronomical Society says.

Pretty good start to the year for astro related stuffs. If you’re in the UK, the Quantrantid meteor shower starts tonight with its peak on January the 12th! news.sky.com/story/quadra... πŸ”­

Cont. This image is special because of its high resolution. The white circle shows the outer edge of the CGM and each quadrant corresponds to a key physical property that is important in the evolution of the CGM! The CGM is a vital component in the evolution of galaxies as it fuels star formation.
