The Evolution of a Scientific American Information Graphic: Stellar Life Cycle

The evolution of a Scientific American information graphic: stellar life cycle

As the art director of information graphics at Scientific American, I’m charged with developing explanatory art for some pretty mind-blowing topics. Our team—text editor, expert author, artist, and me—often works toward illustrating a process or concept that has never been rendered before, or may have only been visualized for other specialists in the field in [...]

How ‘UFOs’ Curb Black Hole Growth

Something unusual has been spotted lurking around several galaxies’ central black holes. Astronomers think it may be limiting the growth of the black holes – and stars elsewhere in the galaxies, too. Astronomers studying nearby galaxies have found a new type of outflow called an ultra-fast outflow, or UFO. An international team of astronomers led [...]

They may come from completely different fields of study, but brain scans and supernovae have more in common than you would think. In a new TED talk, Michelle Borkin explains how software developed for use in a hospital was able to help astronomers study the structure of supernovae.

When a star becomes a white dwarf — an old, extremely dense star that would have once been similar to our own Sun — the eventful part of its life is over. It releases what heat and light it has left over billions of years, slowly cooling until it no longer shines. Usually. Some white [...]

How did the Christmas gamma-ray burst explode? No, it’s not a geeky Christmas cracker joke, it’s a real question scientists have been trying to answer since Christmas day last year, when a gamma-ray burst called GRB 101225A first lit up the sky. The Christmas burst, as its come to be known, exhibted some rather unusual [...]

As If 1 Giant Black Hole Weren’t Enough, What’s a Galaxy Doing with 3?

Last Thursday, my colleague John Matson described a truly amazing galaxy known, somewhat unromantically, as BX442. It has a majestic spiral pattern while hundreds of its galactic contemporaries were gawky and misshapen—a peculiar and special anomaly which suggests to many astronomers that cosmic pinwheels are ephemeral art forms, like Tibetan sand mandalas. John’s piece spurs [...]

Habitable and not-so-habitable exoplanets: How the latter can tell us more about our origins than the former

On 29th September this year, astronomers announced the discovery of an exoplanet called Gliese 581 g. This planet, they said, was exactly the right distance from its star for water to exist on its surface, with a good chance that it could hold an atmosphere. These two properties are very important when judging whether a [...]

Lonely Planets of the Cosmos

Hot Jupiters are special beasts in the exoplanetary menagerie.
