Who Turned Out the Lights?
“E-bomb” may see first combat use in Iraq
Weapons designed to attack electronic systems and not people could see their first combat use in any military attack on Iraq.
[…]
High Power Microwave (HPM) devices are designed to destroy electronic equipment in command, control, communications and computer targets and are available to the US military. They produce an electromagnetic field of such intensity that their effect can be far more devastating than a lighting strike.

Someday I gotta build one of these. It would put my electrical engineering skills to the test. 🙂
Whew!
Asteroid to miss – this time around
stronomers have ruled out an Earth impact from asteroid 2002 NT7 on 1 February 2019 – but they say, as yet, future collisions have not been completely excluded. 2002 NT7, a two-kilometre-wide (1.4 miles) chunk of rock, was discovered on 9 July. Initial estimates of its orbit suggested there was a small chance of it colliding with our planet in 17 years’ time. However, the latest observations accumulated over the last few days have confirmed the asteroid will fly harmlessly by.

Ghostly Asteroids Offer Dark Clues To Missing Matter
"Astronomers have lost thousands of comets. A University of Melbourne physicist thinks they may still be there, just invisible and some of them potentially on a collision course with Earth."
"Dr Robert Foot suggests that many of the missing comets could be made of an exotic material called 'mirror matter', a new type of invisible matter that a small group of physicists believe could be the elusive 'dark matter'. Dark matter is considered the cosmic scaffolding that makes up most of the universe, but nobody can identify it."
