My new book, Amazing Worlds of Science Fiction and Science Fact, is out now from Reaktion Books! It's all about the exoplanets that astronomers are discovering, seen through the lens of science fiction, featuring interviews with astronomers and sf authors reaktionbooks.co.uk/work/amazing...
I'm absolutely honoured to see Amazing Worlds reviewed in Locus!

"Examining how the cutting-edge science of exoplanets has enriched or superseded science fiction’s most beloved planetary conventions ... his twin passions for the cosmos of what is and of what might be kept me enthralled throughout."

New, by me: complex organic molecules, which are among the most basic building blocks of life, have been found as ice encrusting dust around a protostar in the Large Magellanic Cloud, evidence that the chemistry for life is present at the earliest stages of star-birth: www.space.com/astronomy/ja...

Worried about 3I/ATLAS? Don't be – it is just a comet, and like cats, comets have tails and do as they please. Here's my guide to 3I/ATLAS (written before perihelion) and how to debunk some of the more extravagant claims about this cosmic cat on the loose: supercluster.com/editorial/do...
Don’t Panic! 3I/ATLAS is Just a Comet
Starting in July 2025, scientists have had the opportunity to study just the third documented interstellar object to enter the Solar System.

What will we lose when the ISS is de-orbited in 2030? The way that science was done on the station, through process, cooperation and peer-review, might not be replicated when commercial stations are launched to fill the void left by the ISS. My latest: www.space.com/space-explor...
The International Space Station will fall to Earth in 2030. Can a private space station really fill its gap?

How compact can neutron stars, which are the ultra-dense relics of stars that have gone supernova, get? I look at a new paper that uncovers a mathematical relation governing neutron star compactness, even if we don't understand the physics going on inside neutron stars www.space.com/astronomy/st...
How compact can a neutron star get before collapsing into a black hole?
A spoonful of this star's matter can weigh a billion tons.

By me: Europa Clipper could be about to intercept ions stripped by the solar wind from the ion tail of comet 3I/ATLAS – but will scientists even be able to make the measurements? If they can, it will be the first ever detection of particles from an interstellar comet. www.space.com/astronomy/co...
Comet 3I/ATLAS could soon shower NASA's Jupiter probe in charged particles.
"We study cometary bodies because they act as time capsules, sealing in material from their formation billions of years ago."

The 30th anniversary of the discovery of the first exoplanet to be found around a Sun-like star was earlier this month. I spoke to the astronomer who made that historic first discovery, Didier Queloz, plus Caltech's Aurora Kesseli, in my new article for Supercluster supercluster.com/editorial/30...
30 Years of Exoplanets: An Astonishing Catalogue of Cosmic Wonder
Astronomers working at NASA’s Exoplanet Archive at Caltech recently announced that the number of known planets around stars other than our Sun had passed the 6,000 mark. It’s been a truly staggering r...

Back in the 1970s, Princeton physicist Gerard K O'Neill proposed that by now millions of us would be living in huge cities in space. So what happened? For my latest article I take a look at O'Neill's dreams of a 'High Frontier', with a nod, as always, to Babylon 5. www.space.com/astronomy/ea...
How one scientist's wide-eyed dream of giant space cities was crushed by reality

In this week celebrating the 30th anniversary of the discovery of the first exoplanet around a Sun-like star, I take a look at what the future holds and how we can expect, at the very least, to double the current count of over 6,000 words by the end of this decade www.space.com/astronomy/ex...

Happy exoplanet day! Today is the 30th anniversary of the reveal of the first known exoplanet around a Sun-like star. Discovered in 1995 and published in Nature on 6 October that year, 51 Pegasi b is what we now call a hot jupiter, but back then scientists were bewildered by this new type of planet!

With the 30th anniversary of the discovery of the first known exoplanet around a Sun-like star coming up next week, my book Amazing Worlds of Science Fiction and Science fact is a great primer on all things exoplanets, and how we interpret them through science fiction.
When Star Trek first aired in 1966, it posited a universe bursting with planetary possibilities—a bold move at a time before anyone knew of a single planet beyond our Solar System.

Brilliant to see Amazing Worlds reviewed in the new issue of Locus: "Amazing Worlds' well-earned sense of wonder, tempered by critical insight, elevates it above catalog of planetary trivia ... Cooper breathes fresh life both into the fiction and the facts." subscribers.locusmag.com/content/buy-...

How does the recent discovery of potential biosignatures on Mars by the Perseverance rover compare to other claims of evidence for life, on Mars and beyond? I find out in my latest article, discussing methane plumes, Martian meteorites, and gases on Venus and K2-18b: www.space.com/space-explor...
How excited should we be about the latest Mars potential biosignature discovery? 'It's arguably the best evidence we have so far'
It's not the first time there have been claims of signs of life on Mars, so why are scientists particularly thrilled now?

New article on my Substack: is technological alien life rare? A new calculation, based on the prevalence of planets with plate tectonics and just the right amount of CO2 and oxygen suggests they might be – but there are reasons for optimism. storiesfromthecosmicfrontier.substack.com/p/rare-earth...
Rare Earth strikes back? Why alien life might be rare
If Earth-like habitats really are scarce, then technological life might be too, with the nearest civilisation possibly being 33,000 light years away – but is our pessimism in error?

Another of the press releases that I wrote for Europlanet & EPSC-DPS2025 and possibly my favourite given its subject matter: how plate tectonics and the right amounts of CO2 and oxygen are crucial for technological life to evolve – and such life could be very rare: www.europlanet.org/epsc-dps2025...

Another of my press releases from EPSC-DPS2025 and it's truly remarkable: how interstellar objects similar to 3I/ATLAS could be captured by protoplanetary discs around young stars and become the seeds of giant planets!

It's been 40 years this month since Carl Sagan's epic science fiction novel, Contact, was published. I explore its themes of SETI, politics, religion and, indeed, contact, plus its legacy and how well it stands up today in my new article for Supercluster

The final frontier: in my new article I explore David Kipping's 'TARS' concept for launching an interstellar mission using a spinning slingshot accelerated by solar wind pressure, which could fling a tiny spacecraft towards nearby stars at up to 1,000km/s www.space.com/technology/s...
Spacecraft launcher named for robot in 'Interstellar' could help us reach another star system. Here's how
The slingshot, called TARS, could in theory accelerate a small spacecraft up to 620 miles per second.

I've been privileged to be working with Europlanet to write press releases for the EPSC–DPS 2025 Joint Meeting in Helsinki this week. The first PR puts the spotlight on Saturn's moon Enceladus, questioning the origin of organic molecules in Enceladus' water plumes www.europlanet.org/epsc-dps2025...
