Gigantic galaxies discovered with the MeerKAT telescope

Two giant radio galaxies have been discovered with South Africa's powerful MeerKAT telescope. These galaxies are amongst the largest single objects in the universe and are thought to be quite rare.  

The discovery has been published online in the Monthly Notices of the Royal Astronomical Society.

The detection of two of these monsters by MeerKat, in a relatively small patch of sky suggests that these scarce giant radio galaxies may actually be much more common than previously thought. This gives astronomers vital clues about how galaxies have changed and evolved throughout cosmic history.

Win-win for wind energy and eagles

While the rapid uptake of wind energy across the globe offers hope of a transition toward sustainability, this same energy can also present a real threat to soaring birds of prey. Now a new tool offers hope of a win-win solution, allowing developers to rapidly identify the best locations for their wind turbines and also minimise the risk of collision for one special bird of prey.

Shrimp-like tanaids mimic hermit crabs

University of Cape Town (UCT) marine biologist Dr Jannes Landschoff describes it as “an intriguing little animal” that lives like a hermit crab but isn’t a crab. Unlike its fellows, this tiny, shrimp-like tanaid also chooses to bed down in empty gastropod shells. A new paper by Dr Landschoff and lead author, UCT master’s student Rouane Brokensha, sheds light on how this miniscule animal is adapted to shell life.
