My Tiny Little Tea Leaves

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.

Japanese artist Takanori Aiba makes tiny, enchanting worlds, such as this fanciful castle wrapped around an imitation bonsai tree. His whole site is a browsing delight. The only pity is that his creations aren’t real places that we can visit.

One of the newest chameleon species discovered in the wild is so small it’s no wonder they’ve slipped through the cracks for so many years. Found in Madagascar, the Brookesia micra is a miniscule 3cm in length, and is so cute that the Geico gecko has started looking for a new job!

Documents seized in the raid on Osama bin Laden’s compound have yielded a bonanza of new intelligence, from names and locations of terrorist suspects to chilling details of al-Qaeda plots to attack targets in the United States and beyond, U.S. officials said Thursday.

Among the files recovered from captured computers and flash drives were documents detailing a previously unknown plan to attack the U.S. commuter rail network, intelligence officials confirmed. The plan, which described a sabotage attack to occur on this year’s 10th anniversary of the Sept. 11, 2001, attacks, was being actively considered as recently as February 2010, Obama administration officials said.
