Once a person gets selected to be an astronaut, he/she has to go through rigorous and extensive training for upto two years to become a fully qualified candidate. These astronauts are made to take survival training, medical procedures, language classes, etc, for them to be considered an efficient astronaut. To that end,  ESA  has a latest training adventure in underground cave where six astronauts from five different space agencies are getting trained for future exploration of uncharted terrains on the Moon and Mars.

As a part of underground exploration, astronauts will have to follow the flow of air and water as telltale signs of new paths ahead. This crew of astronauts will be made to learn how to trace wa

Black holes, the enigmatic space objects that lurk at the center of all large galaxies, have always been surrounded with mystery. Scientists and space enthusiasts are constantly coming up with new research around black holes in the hope of uncovering something new. To that end, a pair of researchers, Kevin Croker, astrophysicist from the University of Hawaii and mathematician Joel Weiner, have come out with a theory that suggests Einstein's general theory of relativity might need some modification. They have identified an error that was made in Einstein’s equations surrounding growth of our universe,  reports  Phys.org.

It is now clear that general relativity can observably connect collapsed stars—regions the size of
