Beyond thrilled to share my latest feature for Scientific American, my little magnum opus on the Habitable Worlds Observatory – NASA's bold new telescope to hunt for alien life.

Are we alone? The journey to find out has just begun.

Enjoy!

My latest feature for New Scientist is on axions – "wonder particles" that could explain dark matter, dark energy, and more.

Bonus, it'll be the cover of the magazine next week, my fourth New Scientist cover of the year. So, give it a read!

The Cow
The Koala
The Finch
The Tasmanian Devil

These are mysterious space explosions we can't explain. Now astronomers have seen one of them doing something bizarre - flashing more than a dozen times. What's going on?

Last year NASA detected a monster quake on Mars, as big as all other known marsquakes combined.

Now scientists have ruled out a meteorite impact as the cause, pointing to unknown tectonic activity beneath the Martian surface.

In April's Starship test flight, the rocket failed to explode properly.

Its termination system didn't have enough oomph.

While no harm was done, the incident raised big concerns. Has SpaceX solved the issue?

Two ice giant planets appear to have smashed into each other in a nearby solar system 1,800 years ago - forming a giant superheated donut seven times larger than our sun.

Just another day in space. Words by me in New Scientist.

NASA is set to launch Psyche tomorrow, a mission to a heavy-metal asteroid of the same name.

Is it the remnant core of a failed planet, with sheets of metal on its surface?

We're about to find out. Story by me in Supercluster.

The FCC just issued its first ever space junk fine to a US firm - wiping $400 million off the company's valuation.

Here's why the fine is such a big deal and what it means for cleaning up Earth's orbit.

NASA has reversed course on scrapping key science being done by the New Horizons Pluto spacecraft.

It will now continue studying the Kuiper Belt and looking for another flyby target through 2028 after an outcry.

JWST just took the best ever image of the Orion Nebula. And it revealed something baffling:

42 free-floating planets seemingly drifting in pairs. Where the hell did they come from?

New feature from me in New Scientist today - and it's also the cover for the magazine this week!

Earlier this year astronomers said they'd found evidence for "dark stars", stars powered by dark matter, first proposed in 2008.

But have they, and what are they?
