Yesterday morning on the way to work, NPR was broadcasting an interview with Sheryl Sandberg and her new book Lean In was mentioned and discussed. Then, when I arrived home, she was on the cover page of the weekly Time magazine that I receive in mail. At night, I saw Piers Morgan had a piece on her and 60 Minutes a program on her. How is it that everyone has a program or release about her on the same exact date? Did they all want to be the first and that was the only way to avoid their content being out dated? But how do they learn about the timeline and schedule of other competitive media. Today, TED reshared an old video of her famous talk, "Why we have too few women leaders", on facebook too. It is as if over night, the world decided to concentrate on her. What happened? How does it work?
Was her book released yesterday?

Earth's Third Radiation Belt!
It was over 50 years ago in 1958 that Explorer 1 and Explorer 3 confirmed the existence of two radiation belts around Earth under Dr. James Van Allen's direction [1]. Van Allen Probes, previously called Radiation Belt Storm Probes (RBSP), were launched on August 30, 2012. The objective of this mission, as its name suggests, is to
"study two extreme and dynamic regions of space known as the Van Allen Radiation Belts that surround Earth. Named for their discoverer, James Van Allen, these two concentric, donut-shaped rings are filled with high-energy particles that gyrate, bounce, and drift through the region, sometimes shooting down to Earth's atmosphere, sometimes escaping out into space. The radiation belts swell and shrink over time as part of a much larger space weather system driven by energy and material that erupt off the sun's surface and fill the entire solar system." [2]
While most satellites are designed to turn off during intense radiation bombardments,Van Allen Probes are built to operate, tolerate, and collect data during such harsh conditions.
It is thus so fortunate and fitting that NASA Scientists have discovered a third radiation belt around our very own home planet Earth using Van Allen Probe's data soon after its launch [3]. To learn more about this discovery, please visit here.

This discovery is a humbling reminder that there is a lot yet to be learned about our home, Earth, let alone other planets and corners of this vast universe.
