Recognize that the very molecules that make up your body, the atoms that construct the molecules, are traceable to the crucibles that were once the centers of high mass stars that exploded their chemically rich guts into the galaxy, enriching pristine gas clouds with the chemistry of life. So that we are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically. That’s kinda cool! That makes me smile and I actually feel quite large at the end of that. It’s not that we are better than the universe, we are part of the universe. We are in the universe and the universe is in us.
Dwell on the beauty of life. Watch the stars, and see yourself running with them.

Solar Storms, With a Chance of Proton Showers

This large solar flare, produced by an active region of the sun (AR9077), triggered magnetic storms and knocked out satellites when it created a solar storm on July 14, 2000. Nicknamed the Bastille Day Event, it was the third largest storm of its kind in the past 30 years, and the biggest solar radiation event since 1989. The Slinky-like loops represent magnetic field lines.
The orbiting Transition Region and Coronal Explorer (TRACE) satellite captured this close-up image after the flare erupted. Recorded in extreme ultraviolet light, it covers a 230,000-by-77,000 kilometer area on the sun’s surface and shows a one-million-degree solar plasma cooling down.

NASA’s newest sun-watching satellite, the Interface Region Imaging Spectrograph (IRIS), sent back its first image of the Sun’s lower atmosphere on June 25 - the clearest picture ever of this mysterious region.
A large dark sunspot is visible in the lower right of the image, but its surroundings are filled with previously unseen features that NASA describes as “a multitude of thin, fibril-like structures.”

The Sharpest View of The Sun
Here is one of the sharper views of the Sun ever taken. This stunning image shows remarkable details of a dark sunspot across the image bottom and numerous boiling granules which appear like kernels of corn across the top. Taken in 2002, the picture was made using the Swedish Solar Telescope operating on the Canary Island of La Palma.

The universe is probably littered with the one-planet graves of cultures which made the sensible economic decision that there’s no good reason to go into space—each discovered, studied, and remembered by the ones who made the irrational decision.

» Self-replicating alien probes could already be here

Mathematicians in Scotland calculate that “self-replicating” alien probes could already have explored our solar system and may still be here but undetectable to our current technologies.

The new calculations, reported in the International Journal of Astrobiology this week, expanded on the previous work by using “self-replicating” probes in the computer models to see how the self-replication would affect the timescale.

The robotic probes could explore our galaxy and self-replicate themselves from and gas, after which the parent and child probes would each set off for a different star, where they would look for and then self-replicate themselves again. The probes would therefore disperse themselves radially across space.

In all the scenarios the scientists looked at, exploration timescales were reduced when the probes were self-replicating, and they concluded that a fleet of self-replicating probes could travel at only 10% of the speed of light and still explore the entire Galaxy in the relatively short time of 10 million years. This is a tiny fraction of the age of the Earth and the scientists say the results reinforce the idea of the “Fermi Paradox.”
Dr Forgan said that the fact that we have not detected or seen any evidence of alien probes in the solar system suggests there have been no probe-building civilizations in the Milky Way in the last few million years or that the probes are so hi-tech we are unable to detect them. Another possibility is that probes could be programmed to make contact only with civilizations that pass a set measure of intelligence, which could be the ability to detect the probes.

I consider this possibility quite likely.  Our planet has had a detectable oxygen signature for at least 2 billion years.  Any alien civilization that can build orbital telescopes should know that Earth is a living planet.
