A new study publishing this week in the Astrophysical Journal by Gary Prézeau of NASA’s Jet Propulsion Laboratory, Pasadena, California, proposes the existence of long filaments of dark matter, or “hairs.” http://ift.tt/1NdQIKk

closely related to sharks but with long, flat bodies and wing-like pectoral fins, mobula rays are ideally suited to swooping through the water - here off the gulf of california - yet seem equally at home in the air, so much so that they have earned the name “flying rays”. mobula rays can reach heights of more than two metres, remaining airborne for several seconds. 

mobula rays are quite elusive and difficult to study, so biologists are not quite sure why they jump out of the water. theories vary from a means of communication, to a mating ritual (though both males and females jump), or as a way to shed themselves of parasites. they could also be jumping as a way of better corralling their pray, as seen with them swimming in a circular formation. 

what is known about mobula rays is that they reach sexual maturity late and their investment in their offspring is more akin to mammals than other fishes, usually producing just a single pup after long pregnancies, all of which makes them extremely vulnerable to commercial fishing, especially as a species that likes to come together in large groups.

CGG POP-UP SHOW | May 13th 2015 | art space tetra | Fukuoka Japan

The Contemporary Guerilla Gallery Berlin is a project by a group of Berlin-based artists. The experimental project explores new ways of dealing with the contemporary art market. Part of the concept of CGG Berlin is independent art selling on eBay, another part is making pop-up exhibitions without external curatorial influence.

At art space tetra we show video works of five of the CGG artists. The video works have a documentary character and thematize the process of art production.

At the opening Hannah Reber and Gert-Jan Akerboom will be present and give a brief introduction of the project and answer questions after the screening.

The CGG Berlin pop-up at art space tetra shows works by:
