It turns out the origins of one of the most essential things in our lives date back over 4.6 billion years. A recent experiment conducted by Ilse Cleeves at the University of Michigan suggests that much of Earth’s (and Solar System’s) water may be older than the Sun, and likely originated as ices that formed in interstellar space. I think the famous picture above (by Melzzeny on DeviantArt) becomes pretty relevant now.
Not to mention, the study indicates that abundant, organic-rich interstellar ices should probably be found in all young planetary systems and that would obviously have implications for the emergence of life elsewhere. Identifying the original source of Earth’s water is key to understanding how life-fostering environments come into being. Read about the team’s work here»

Visualizing The Hidden Cosmos | The Making Of ‘Dark Universe’ (by The Creators Project)
"The team behind Hayden Planetarium’s latest space show, Dark Universe, including Neil deGrasse Tyson, detail the developments in research and technology that have enabled the show’s unprecedented views of our galaxy. Find out how they were able to simulate and visualize the cosmic mysteries of dark matter and dark energy, which make up 95% of the universe invisible to the naked eye. "
The only two reactions to this realization.

There is no thought nobler…
