  • A meteorite that fell to Earth in October 2008 contained scores of small diamonds.
  • The diamonds and impurities found inside them suggest the rock came from inside a planet.
  • Scientists think the planet was destroyed 4.5 billion years ago and was the size of Mercury or even Mars.
  • Asteroid TC 3, as it's called, may be the first pristine chunk of a "lost" planet ever recovered on Earth.


After a 4.5-billion-year journey through space, a car-size rock fell to Earth on October 7, 2008. The stony meteorite, called asteroid 2008 TC 3, plunged through the atmosphere, exploded, and rained its pieces over the Nubian Desert in Africa.

Meteorite hunters recovered about 50 fragments, which researchers later named the "Almahata Sitta" collection after a nearby train station in Sudan.

But while many stony meteorites hail from Mars, these were peculiar: They contained a bunch of tiny diamonds.

Scientists now think those gems and the impurities found inside them could only come from the heart of a Mercury-to-Mars-size planet. This means the rock that fell to Earth nearly a decade ago was part of a "lost" planet formed — and completely destroyed— at the dawn of the solar system.

Good stuff.

Brilliant images Doone. I often wonder why the planets form a disk around a star and not a ball

Wonderful collection of images of young solar systems

Yes, it was all over the news, & a baby explosion 9 months later.

Do you remember it?

That was just after we moved here.

The Day The Sun Brought Darkness

About 30 years ago, on March 13, 1989, the whole province of Quebec, Canada, suffered a blackout that by now has reached legendary proportions among astronomers and electrical engineers. Still, what made it reach this status wasn’t its proportions, but the fact that it was caused by the sun, or a solar storm to be more exact.

Three days earlier, astronomers noticed a powerful explosion on the sun, and just a few minutes after that, the Sun’s magnetic forces had already released a cloud of gas worth more than a billion tons. The cloud headed straight for Earth’s direction and at about 1.000.000 miles/hour, it went straight for us. It even jammed some radio frequencies, which most of Europe thought was the work of Russians, but they soon found out the true cause.

Neat photograph of the pilot among the aurora. I haven't had the oppertunity to see the aurora. I read it sometimes comes to lover latitudes. That's probably a good because I understandin middle lattitudes can upset the power grid.
