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.

SmarterEveryDay’s Destin Sandlin captured this astonishing video of the International Space Station transiting Monday’s solar eclipse. Fast forward to 3:50 for the magical moment. And in case you missed it, below is NASA’s still photo of the ISS transiting the sun at five miles per second.
The psilocybin in magic mushrooms is a potent psychedelic for animals. But what good is the psilocybin for the shrooms? New genetic research from Ohio State University suggests that the psilocybin might act as an insect repellant, protecting the mushrooms. From New Scientist: The gene cluster (linked to psilocybin production) is found in several distantly […]
In elementary school, I knew a boy who would impress us by pulling the legs off a daddy longlegs and popping the body in his mouth. I think he would appreciate this Deep Look video about how daddy longlegs can drop up to three of its limbs when threatened by a predator and still survive.

Toaster ovens are the perfect appliance for small things like toasted sandwiches and roasted garlic (try it!), but anything more involved usually requires a full-sized conventional oven.However, despite its small size, the Wolfgang Puck Pressure Oven can handle anything from baked pastries to broiled meats. This kitchen appliance has a minimal countertop footprint, and cooks […]
