...research principles. It follows that what is known about a given scientific discipline has the potential to change with the publication of each new piece of research. The publication of new knowledge is not a given. For new knowledge to be published, it has to pass the assessment of peers working in the field (i.e. other expert scientists). Once agreed, this new knowledge...

Tracing the origin of O2 Oxygen is one of the most abundant elements in our galaxy and solar system, and we take the free molecular oxygen that makes up 20% of our atmosphere for granted with every breath. So why is finding oxygen in a comet such a big deal? Oxygen readily binds with other abundant elements such as hydrogen (H) or carbon ( C ) to form water...

Black holes are what’s left after large stars die and their cores collapse. They are incredibly dense, with gravity so strong that nothing can move fast enough to escape them, including light. Astronomers are keen to study black holes because...
