How do you make a star?
It’s not easy to make a star, you need a lot of cold space and a huge amount of hydrogen. But if you manage to do that then you can have your very own Sun sized star to keep you warm in winter.

The night sky is full of stars and some of the very brightest we see have some very interesting characteristics. Next time you’re looking at Sirius or Canopus you’ll be able to appreciate just how big they are compared to our very own star – the Sun.
(And we can do something about it.)
Life needs CHNOPS, the six essential elements Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, and Sulphur. Curiosity found them on ancient Mars, but a new study shows Earth was born without them. Only a lucky impact with Theia made our world habitable. In contrast, Venus never stood a chance. Meet the three planetary siblings and discover why only Earth became a cradle for life.
Mars’s mantle contains ancient fragments up to 4km wide from its formation—preserved like geological fossils from the planet’s violent early history.
Cosmic rays are hitting the atmosphere constantly. One of the products of the collisions is muons, and we can detect muons on the surface of the Earth to learn about the cosmic rays.
