SUNSET SKY SHOW: The two brightest planets in the night sky are converging for a spectacular close encounter. On June 30th,
Jupiter and Venus will be just a fraction of a degree apart, forming a
pair so bright that you can see them even before nightfall. Check http://spaceweather.com for observing tips and more.
ENCORE: A computer virus that bombards you with pop-up ads is one thing. A
computer virus that shuts down a city’s electric grid is another.
Welcome to the new generation of cybercrime. Discover what it will take
to protect our power, communication and transportation systems as
scientists try to stay ahead of hackers in an ever-escalating game of
cat and mouse.
The expert who helped decipher the centrifuge-destroying Stuxnet
virus tells us what he thinks is next. Also convenience vs.
vulnerability as we connect to the Internet of Everything. And, the
journalist who wrote that Google was “making us stupid,” says automation
is extracting an even higher toll: we’re losing basic skills. Such as
how to fly airplanes.

GEOMAGNETIC STORM WARNING: A CME is heading directly for Earth, and it
is expected to sweep up one or more lesser CMEs before it reaches our
planet on June 22nd. The combined impact is likely to spark polar
geomagnetic storms and high-latitude auroras. Visit http://spaceweather.com for more information and updates.
ENCORE: It’s hard to imagine the twists and turns of evolution that gave rise to Homo Sapiens.
After all, it required geologic time, and the existence of many
long-gone species that were once close relatives. That may be one
reason why – according to a recent poll – one-third of all Americans
reject the theory of evolution. They prefer to believe that humans and
other living organisms have existed in their current form since the
beginning of time.
But if you’ve ever been sick, you’ve been the victim of evolution on a
very observable time scale. Nasty viruses and bacteria take full
advantage of evolutionary forces to adapt to new hosts. And they can do

may help us prevent the next pandemic. Also, while antibiotic resistance
is threatening to become a major health crisis, better understanding of
how bacteria evolve their defenses against our drugs may help us out.
And the geneticist who sequenced the Neanderthal genome says yes, our hirsute neighbors co-mingled with humans.
It’s Skeptic Check … but don’t take our word for it!
SOLSTICE AURORA WATCH: On June 18th, the sun produced its biggest flare
in nearly two months. The M3-class explosion caused a brief
low-frequency radio blackout over North America and hurled a CME into
space. A glancing blow from the CME is likely on June 21st , possibly sparking a geomagnetic storm and solstice auroras. Check http://spaceweather.com for updates.

NOCTILUCENT CLOUDS REACH THE USA: The northern season for noctilucent
clouds began on May 19th when NASA's AIM spacecraft spotted a patch of
electric blue over the Arctic Circle. Since then the clouds have been
spreading south. This week, for the first time in 2015, they crossed the
border into the lower 48 US states. Seeded by meteoroids and floating
near the edge of space, these eerie-looking clouds are increasingly
visible to mid-latitude observers, possibly as a result of climate
Earth may be the cradle of life, but our bodies are filled with
materials cooked up billions of years ago in the scorching centers of
stars. As Carl Sagan said, “We are all stardust.” We came from space,
and some say it is to space we will return.

Earth is entering a stream of debris from an unknown comet, and this is
causing one of the most intense meteor showers of the year. Ironically,
most sky watchers won't notice because the shower peaks in broad
daylight. We only know it's happening because a radar in Canada is
picking up echoes from meteoroids streaking through the blue sky
overhead. Astronomers call these meteors "Arietids" because they emerge
from the constellation Aries not far from the June sun.

sunrise in the mornings ahead, visit http://spaceweather.com
