Scientists have announced the discovery of a sub-surface
ocean on the Saturnian moon Enceladus -- explore the tiny world's icy
surface and water ice geysers in this stunning collection of images from
NASA's Cassini mission.
Gravity measurements indicate the small moon Enceladus has an
ocean sandwiched between its rocky core and icy shell, a finding that
raises the prospects of a niche for life beyond Earth.
It can be stressful being a small asteroid -- not only do
they risk collision with the planets any time, they are also slowly
being eroded by the sun.
Earth’s finishing touch came with a wallop when a Mars-sized
hunk of real estate crashed into the fetal planet some 95 million years
after the birth of the solar system -- later than some astronomers
thought -- sending up debris that eventually formed moon.
NGC 1316 has a lot of skeletons in its closet -- literally.
Last month's BICEP2 discovery of gravitational waves is
compelling evidence for the inflationary period just after the Big Bang.
But what if there's another explanation?
