the plane of the galaxy around scorpius. the second brightest object in the image, above the galaxy, is antares. the very brightest, above and left, must be a planet - perhaps mars. the pair of bright stars that just sneak into frame at bottom right are alpha and beta centauri; one of the stars in the alpha centauri star system, proxima centauri, is the closest star to the sun.

18 frames over 22 hours. on january 21st, the spacecraft used a lunar gravity assist to escape the earth-moon system and enter a heliocentric orbit.

NASA’s Revived STEREO-B Could Save Us From A Trillion Dollar Disaster

“So while there may not be a danger to you, there is a huge danger to electronics, ranging from automobiles to transformers to — most frighteningly of all — the entire power grid! That’s the real danger of a solar storm: an event similar to the 1859 Carrington event could cause anywhere between an estimated $1-to-$2 trillion of property damage, mostly due to electrical fires and damage to our infrastructure.”

In 1859, the Sun surprisingly increased in brightness so significantly for just a brief while that it was noticeable from Earth during the day. Less than 24 hours later, aurorae were visible so brightly and so far south that people awoke in the middle of the night, thinking it was dawn. But in addition to the spectacular sights, there were also downsides: telegraph wires spontaneously caught on fire, causing significant amounts of damage. The physics behind it is simple and straightforward, as the charged particles emitted from a solar flare interacted with the Earth’s atmosphere, changing its magnetic field over time and inducing current in any long-length (or coiled) wires. In the 21st century, such a flare would be a trillion dollar disaster, and we have very little to defend against it in place. Thankfully, with STEREO-B back online, our best early warning system is now 100% functional again!

Go get the full story about solar storms, their human impact and how NASA’s revived satellite just might be key to avoiding catastrophe when the inevitable occurs!


comet elenin, photographed by stereo b, august 2011.

based on the trajectory of its brief visit to the inner solar system, comet elenin (c/2010 x1) was once an outer oort cloud object with an orbit of millions of years. perturbed inward (possibly by a passing star) the comet partially disintegrated while passing close to the sun (0.48 au), and is now in a 12,000 year orbit in the scattered disc.

top: 7 frames, composite of 14 images. bottom left & right: both component sequences. all photographed 6-12th august.
