Un equipo de astrónomos consiguió capturar en imágenes los restos erosionados de más de un centenar de galaxias enanas que se están transformando en galaxias enanas ultra compactas, es decir, en objetos con masas mayores que la de los cúmulos estelares, pero mucho más pequeñas que las galaxias enanas. Los hallazgos fueron realizados utilizando el telescopio de Gemini Norte, la mitad boreal del Observatorio Gemini que opera NOIRLab de NSF y AURA, y confirman que muchas galaxias enanas ultra compactas son probablemente los fósiles de galaxias enanas normales cuyas capas exteriores se desprendieron.

The analysis, conducted by Imperial College London researchers and published today in Nature Climate Change, shows that some states will need new policies to ensure a ‘just’ transition.
Do we really know how the brain works? In the last several decades, scientists have made great strides in understanding this fantastically complex organ. Scientists now know a great deal about the brain’s cellular neurobiology and have learned much about the brain’s neural connections, and the components that make up these connections.

Viruses are the most prevalent biological entities in the world’s oceans and play essential roles in its ecological and biogeochemical balance. Yet, they are the least understood elements of marine life. By unraveling the entire genome of a certain marine protist that may act as a host for many viruses, an international research team led by scientists from Stony Brook University sets the stage for future investigations of marine protist genomes, marine microbial dynamics and the evolutionary interplay between host organisms and their viruses – work that may open doors to a better understanding of the “invisible” world of marine viruses and offers a key to the ecology and health of oceans worldwide. The research is published early online in Current Biology.
