This is a drawing of what the edge of the solar system might look like, as envisioned by plasma physicist Merav Opher. One of the few women in this field, Opher is also one of the top scientists, of any gender, studying what happens at the edges of space. John Rennie has written a great profile of Opher and her work. You really should read it. I like Rennie's work a lot. He's one of those amazing writers who can make abstract, theoretical physics feel as immediate, intense, and important as it actually is. To wit:
“The edge of the solar system” is more than a turn of phrase. A tenuous, invisible wind of ionized gas billows off the sun at a million miles per hour, carrying with it the sun’s magnetic field. It does not radiate out infinitely: far beyond Pluto’s orbit, this solar wind abruptly slams into the thin interstellar medium and the scattered gaseous remnants of exploded stars. That border defines what astronomers call the heliosphere.
Just a few years ago, Opher played a key role in explaining why the heliosphere is unexpectedly lopsided and off-kilter. Now an assistant professor in Boston University’s astronomy department, Opher is interpeting data that suggests that part of the heliosphere’s edge may be a churning magnetic froth, which could have broad implications for astrophysics.

Remember back to the time when people thought java was just a hip way to talk about coffee? Or you vaguely remembered from geography class that it’s an island in the South Pacific? We’ve come a long way since then and now that we’ve rocket blasted into the tech future, you’re going to need to […]
Plastic is so 2013. You don’t want to buy something only to throw it away or lose it and barely care. You like nice things and want to hang onto them. The Plazmatic lighter here is a high quality, high tech alternative to the typical cheap, plastic lighter you get at the old gas station. […]
Real engineers build things. Super cool engineers build things with their hands and fingers, like our engineering forefathers did. No idea where to even begin to do that? This step by step Arduino course is now 92% off and is going to get you up and running, from zero to hero, in no time. So […]
