ASTRONOMY & SPACE

Some scientists question whether dark matter is even real, and suggest that the mysteries it was conjured to solve could be explained by a better understanding of gravity.

The planet Vulcan? Hey, wasn't that just a made-up planet Gene Roddenberry created for Star Trek? Not at all, gentle reader. For a period of many years in the late nineteenth century, some, if not all, of the world's astronomer's believed in the existence of a planet Vulcan that orbited the Sun inside the orbit of Mercury.

Is it possible to transport to other dimensions using a black hole as a passage? Could we travel back in time?

New information about what is inside Mars shows the Red Planet has a molten liquid-iron core, confirming the interior of the planet has some similarity to Earth and Venus.

Mercury is, next to Pluto, the second smallest planet in our solar system and the one closest to the sun. Due to its proximity to the sun it has the smallest “year” (time required for a full orbit around the sun), equal to 0,24 of an earth year.
