I shouldn't enjoy this as much as I do.  But I do. And I'm owning it.

Tomato lovers, rejoice, for science has achieved the impossible: the perfect supermarket tomato. The Garden Gem won’t bruise during shipping, it resists many of the major diseases that regularly decimate tomato crops, and it is a flesh-producing powerhouse, turning out up to 22 pounds of tomatoes per plant, which is...

Pluto spotted on Pluto

Pareidolia at its best...

A scientist has found a formation on the dwarf planet Pluto that looks like another Pluto in the universe.

New Horizons photo of minor planet Pluto is remarkably similar to 1979 painting by Don Dixon

A thousand times this.
 
And if you don't know better by now, it's high time you learned.

The latest image of Pluto's surface, a surface covered in mountainous terrain, mountains as high as 3500 meters, has been processed by Roman Tkachenko. Wow. Just look at it, it's stunning. And might I add, looks nothing like Triton up close. A young, and likely geologically active surface with diverse topography. Pluto ❤

This image was taken 77,000 km from Pluto, about 1.5 hours before New Horizons made its closest approach to the dwarf planet. What a beauty!

Why do the planets of the solar system orbit in a flat plane, all in the same direction?
 
Planetary systems form out of giant clouds of gas and dust, and the individual grains of dust, and the individual molecules of gas, are moving around inside those clouds fairly randomly.  Gravity is holding the cloud together, but the individual particles can get away with doing some pretty crazy stuff in there.

Interstellar clouds as a whole, though, usually have some kind of global spin to them.  Think of it like ants on the Earth's surface:  The ants are moving every which way, but the Earth itself rotates in a big west-to-east circle every 24 hours, and those ants are dragged along for the ride.  Only  our space ants aren't constrained to only the outer layers of the space ball.

Now, some of these particles will be be blowing and flowing from north-to-south, others will be blowing south-to-north, and a bunch will be heading east-to-west, but the majority of particles will have some sort of west-to-east motion. 

If these west-to-east moving particles bump into a north-to-south or a south-to-north moving particle, they'll give them a west-to-east kick.

If an east-to-west travelling and a west-to-east travelling particle crash into each other, their  motion will cancel out, and all that will remain is their north/south motion.  This works to eliminate east-to-west moving particles, as they are in a minority.

If a north-to-south and a south-to-north run into each other, their motion will cancel out, and they'll only have their east/west motion left.  This works to flatten out the cloud into a disk rotating in a west-to-east direction over time.
 
Why are planets in our solar system orbiting on approximately similar surface?

Is there any exceptions in other solar systems?

We not only could do this tomorrow, we've already done it! The governments of Canada and Manitoba ran a trial in the 70s, to great results. It reduced the cost of and weight on the medical system, eliminated the social prejudices that come with welfare and EI, simplifies the social safety net, reduces bureaucracy, supports small business, and stabilizes small towns and rural communities.
 
A guaranteed annual income would solve the problem of poverty while actually saving public money, argues Mark Sarner.

From Hogfather :

“Look…how would you make sure everyone in the world was well fed?” she demanded.
“Me? Oh, well, I…” The oh god spluttered for a moment. “I suppose you’d have to think about the prevalent political systems, and the proper division and cultivation of arable land, and—”
“Yes, yes. But he’d just give everyone a good meal,” said Susan.
“Oh, I see. Very impractical. Hah, it’s as silly as saying you could clothe the naked by, well, giving them some clothes.”
