A steady wind, discovered by ESA’s Cluster mission, is slowly escaping from Earth’s plasmasphere - the torus of plasma that surrounds our planet’s atmosphere. The outflow amounts to almost 90 tonnes a day. Predicted by theory two decades ago, this is one of the main mechanisms that replenishes Earth’s magnetosphere with fresh plasma.
A new dataset called Bedmap2 gives a clearer picture of Antarctica from the ice surface down to the bedrock below. Bedmap2 is a significant improvement on the previous collection of Antarctic data—known as Bedmap—that was produced more than 10 years ago.
An online map that tracks in near real-time the vegetation area of all the world’s forests simultaneously will launch next month, after a preview was shown at a United Nations summit yesterday.

The amount of publicly-available data available on Twitter, and a new data-visualization tool really hammers that home — developer Santiago Ortiz has mapped out the relationships between every Twitter employee based on their tweets to each other. Ortiz used Twitter’s API to pull all the tweets authored by Twitter employees for a one-week period, and then filtered those tweets by only those made between employees.
The meteorite that struck central Russia last week, which injured around 1,000 people as it broke apart over a section of the Ural Mountains and sent shockwaves across the ground below, was but one of thousands that have impacted our planet over the past four millennia.
Concert mosh pits are a niche phenomenon even among humans, but researchers at Cornell have found that their movement can be modeled using parameters based on the collision of gas particles.
It was in 1901 — 112 long years ago — that the star GK Persei first exploded in a spectacular nova that reached a magnitude of 0.2, making it the brightest until Nova Aquilae 1918.
Cowboys Stadium currently boasts the largest jumbotron in the NFL — a behemoth of an LED measuring 160 feet wide and 72 feet tall — but how does Dallas’ Texas-sized display compare to the rest of the NFL’s set ups?
