Mercury is tiny, barely bigger than the Moon. Its metallic core makes up 70% of the planet’s mass, vastly exceeding Earth’s 32% and Mars ’ 25%. It’s unlikely that the core actually formed like this.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

A lot of the science from our accelerators is published long after collisions end, so storing experimental data for future physicists is crucial.

A researcher, Heikki Mäntysaari from the University of Jyväskylä (Finland), has been part of an international research group that has made significant advances in modeling heavy ion collisions. New ...

Astronomers may have recorded the violent birth of one of the weirdest objects our Universe is capable of producing.

In the 17th century, astronomers Christiaan Huygens and Giovanni Cassini trained their telescopes on Saturn and uncovered a startling truth: the planet's luminous bands were not solid appendages, but ...

For decades, Uranus baffled scientists because it seemed to have no internal heat. Now, new computer modeling shows the planet actually emits more energy than it receives from the Sun. This subtle ...

The striking thing about this is that repeating the procedure on the star turned up no evidence of carbon-based chemicals, even though the system is young enough that it should still have a ...

When two massive black holes slammed into each other earlier this year, astronomers were able to observe it in the clearest detail to date. Albert Einstein, the father of the theory of general ...

Black holes are so strange that physicists have long wondered if they are quite what they seem. Now we are set to find out if they are instead gravastars, fuzzballs or something else entirely ...

A fresh black hole merger detection has offered the clearest evidence yet for Einstein’s relativity and Hawking’s predictions. Scientists tracked the complete cosmic collision, confirming that black ...
