Title:      Hot news from hot Venus
Abstract:
After decades of space exploration, the misterious Earth's twin planet
jealously keeps most of its secrets hidden below its persistent cloud
coverage. Despite both planets were certainly born as nearly identical
bodies, Venus' cruel fate has condemned it to hell conditions for life
in its obscured surface, at the time that its atmosphere is a living
paradox where the planet rotates as slow as fast its atmosphere is. And
the history of its exploration clearly teaches a simple rule: Venus is
never as expected.
