Orchids are weird - I don't give a flying duck about your Flowers, Mate!

The flying duck orchid is native to Australia.

Side note:

Why did Eisenhower let Sputneck  fly over the US - when US technology was able to do it before them?

To set a presidence allowing sattellites to fly over (USSR) another country.

Yes, that is pretty amazing how we see a black hole now.

First ever black hole image released
The first ever picture of a black hole: It's surrounded by a halo of bright gas pulled in by the hole's gravity

Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy.
It measures 40 billion km across - three million times the size of the Earth - and has been described by scientists as "a monster".
The black hole is 500 million trillion km away and was photographed by a network of eight telescopes across the world.
Details have been published today in Astrophysical Journal Letters.
Prof Heino Falcke, of Radboud University in the Netherlands, who proposed the experiment, told BBC News that the black hole was found in a galaxy called M87.
"What we see is larger than the size of our entire Solar System," he said.
"It has a mass 6.5 billion times that of the Sun. And it is one of the heaviest black holes that we think exists. It is an absolute monster, the heavyweight champion of black holes in the Universe."

What Was It Like When Venus And Mars Became Uninhabitable Planets?

Wait fifty years and you will likely see something similar hapening on earth due to climate change (vs the shut down of the magnetic core that at least Mars likely had).

It's likely better than being hit by a turd in space.

Flushing Toilets

Today, astronauts actually use flushing toilets, that actually flush with air, rather than water. First, the air flow draws the waste away from the body, then flushes it into storage tanks. All of the liquid waste from the spacecraft is stored together in a holding tank, which is periodically dumped overboard, where the liquid evaporates.

Solid waste, on the other hand, goes into a container that’s exposed to the vacuum of space. The vacuum completely dries out the solid waste, which is taken back to earth for disposal.

I always assumed that they brought their poop back with them
