The universe’s earliest epochs appear to be written into the small dwarf galaxies orbiting our own galactic home, the Milky Way.
You’re probably sitting still, right? Wrong, absolutely wrong. Not only are you on a spinning orb, but you’re also travelling around 108,000km/h around a star, in a galaxy that, observations imply, is sailing through space at over two million km/h.
Astronomers from the European Space Agency’s Gaia mission will release the biggest map of our galaxy ever tomorrow, using data collected by the Gaia space telescope. That includes 1.7 billion stars, as well as new information that could potentially solve some cosmic mysteries.
