What’s Up Wednesday #26 - Mars & Our Universe, Spending your time, Art

Happy Wednesday!

Our Universe 👽

🚀 After the landing of Preservance on Mars on the 18th of February the first images taken by the rover are now on the internet. This article shows them. It is really astonishing how the data is passed back to earth. The rover has direct links which are up to 10 bits/s which are good for sending commands and checking its state. For images, the rover makes use of the ESA Mars orbiters. Then the connection is up to 1 gigabit per second! That’s way faster than my internet connection! Now enjoy a image of Mars:

Mars

🌌 This map shows the universe in different zoom levels. It is astonishing how different the local and global vicinity of our universe differs. The first zoom level shows the observable universe. Our universe is 14 billion years old, so the furthest we can see is the distance light covers in 14 billion years. You see a mesh of white. The white areas are superclusters, the black areas are void. A supercluster is a group of several clusters, which itself are a group of galaxies. Zoom in several times and you arrive at our Galaxy, the Milky Way. This zoom level shows the vicinity of our sun and nearby stars. You can see the stars of the Orion Belt (which you can observe from the northern hemisphere very well) are less than 1000 light-years away from us. And there are so many more stars. I really wonder how the night sky would look from other places in the universe.

Spending your time

Most of us are so stuck on the short-cycles of urgency that it’s difficult to even imagine changing our longer-term systems. - Seth’s Blog


I promised to wake up and living my life. Can’t believe I am losing my time by hating myself because I am not spending it right. - Lyrics of Open Blinds

Art are things with a new story

This artwork is a cube of glass with a cool story. „He constructs glass objects that fit exactly into FedEx’s shipping boxes and then ships them to galleries and museums without any protection against damage. And each time the work is shipped — say from one gallery to another — it’s unwittingly altered further by a system created by a massive multinational corporation.“
