I thought the explanation I’d given about black holes was family-friendly; but after what she had said, I had to rethink my examples Read more in the a job that changed me series In the first year of my science degree, I was fortunate to land a job as an astronomy guide at the Sydney Observatory. In my role, I would lead tour groups of about 20 people. We’d look at stars and planets through telescopes. If the skies were filled from horizon to horizon with clouds, we’d explore more of the universe through a 3D theatre. And to peer beyond what our telescopes could see, we’d pile inside the cosy planetarium, seeing what the light pollution of Sydney and clouds would often obstruct from our view.

After five days of living underwater, Analog Astronaut Commander Dr. Musilova and her crew return to terra firma, affected by higher pressures and the team's disconnection from home.
In beef cattle production, determining the ideal time to sell makes all the difference in a producer's costs. This is because, once an animal reaches its natural growth limit, it stops gaining weight significantly. From that point on, every additional day in a feedlot means spending money on feed without gaining meat in return.
A tour of the three caves in southern Spain suggests that people in the area cannibalized one another as funerary practice over many generations.
