Two local CubeSats part of European QB50 project

  Two South African built CubeSats are due for launch from the international space station in January 2017 as part of the QB50 project. They are ZA-AeroSat from the University of Stellenbosch and nSight from the SCS Aerospace Group. The QB50 project will fill a gap in the study of the region below the ionosphere. […]

Sub-Saharan Africa produces less CO2 than Europe

  Scientists have produced the first global maps of human emissions of carbon dioxide ever made solely from satellite observations of the greenhouse gas. The maps, based on data from NASA’s Orbiting Carbon Observatory-2 (OCO-2) satellite and generated with a new data-processing technique, agree well with inventories of known carbon dioxide emissions. No satellite before […]

Close galactic encounter leaves “nearly naked” supermassive black hole

  Astronomers using the super-sharp radio vision of the US National Science Foundation’s very long baseline array (VLBA) have found the shredded remains of a galaxy that passed through a larger galaxy, leaving only the smaller galaxy’s nearly-naked supermassive black hole to emerge and speed away at more than 3600 km per second.  The galaxies […]

Cosmic re-ionisation to be explored in the Karoo

  A great mystery confronting astronomers is expected to be resolved with the installation of a new telescope array in the Karoo, the hydrogen epoch of re-ionisation array (HERA). Cosmic re-ionisation corresponds to the epoch when the neutral intergalactic medium (IGM) is re-ionised by the first luminous objects (stars, black holes). Probing this last unexplored […]
