Many of us know that a 3-D model of the Earth, moon, sun and planets used to explain the way these bodies work is called a planetarium. But few are familiar with a tellurian (tellurium), a mechanical ...

For the first time since 2008, two new planets are being added to one of northern Maine's most famous — and scientifically accurate — roadside attractions. Dwarf planets Haumea and Makemake are the ...

If you’ve ever seen an illustration of the solar system, the odds are good that it was wrong. Not that it messed up the order of the planets, but that the scale was completely off. "Every single ...
