Subject: Celeste - sky surveys

Astrophysicists, statisticians and computer scientists have developed Celeste, a new statistical analysis model designed to enhance one of modern astronomy’s most time-tested tools: sky surveys.

The roots of tradition run deep in astronomy. From Galileo and Copernicus to Hubble and Hawking, scientists and philosophers have been pondering the mysteries of the universe for centuries, scanning the sky with methods and models that, for the most part, haven’t changed much until the last two decades. Now a Berkeley Lab-based research collaboration of astrophysicists, statisticians and computer scientists is looking to shake things up with Celeste, a new statistical analysis model designed to enhance one of modern astronomy’s most time-tested tools: sky surveys.

not quite sure // universe and sky.. I mean it seems shortsighted to call the universe sky. Most of us don’t have a telescope.

the universe isn’t called the sky. the sky is what astronomers look at to see the universe. and you don’t need a telescope because the universe is all around you. just outside your skin.

OK

Well then, how about the sky is our window to energy from other electromagnetic energy sources?

Fucked if I know how to keep our window clean but.

Rain keep the skys clean, here is a recent 2015 study on rain cleaning air, there are many other studies going on and past studies

http://news.mit.edu/2015/rain-drops-attract-aerosols-clean-air-0828

from the article

As a raindrop falls through the atmosphere, it can attract tens to hundreds of tiny aerosol particles to its surface before hitting the ground. The process by which droplets and aerosols attract is coagulation, a natural phenomenon that can act to clear the air of pollutants like soot, sulfates, and organic particles.

Atmospheric chemists at MIT have now determined just how effective rain is in cleaning the atmosphere. Given the altitude of a cloud, the size of its droplets, and the diameter and concentration of aerosols, the team can predict the likelihood that a raindrop will sweep a particle out of the atmosphere.

From article “Most astronomical image analysis methods look at a bunch of pixels and run a simple algorithm that basically does arithmetic on the pixel values” … “Our job is to start from the pixel intensities in the images and work backwards to where the light sources were and what their characteristics were.”

I don’t see the difference between the old and new software, the description of both looks the same to me.
