ESA's Gaia spacecraft reveals the largest image of the Milky Way with 1.7 billion stars, aiding astronomers in studying galaxy formation and evolution.
Since the dawn of history, outer space has always caught the imagination of people across the continents and different cultures. However most of what we currently know about space has been discovered since the beginning of the space age over half a century ago.

The following is a huge infographic showing the true scale of the solar system with all its planets, minor bodies and the most famous probes we have sent out into deep space. Scientists measure distances in our solar system in astronomical units (AU).
This spiral galaxy, called NGC 3982, looks similar to our own galaxy but it is much smaller. NGC 3982 spans about 30,000 light-years which makes it roughly one-third of the size of the Milky Way galaxy. It is located about 68 million light-years away in the constellation Ursa Major. This image is composed of pictures taken by the Hubble Space Telescope’s Wide Field Planetary Camera 2 (WFPC2), the Advanced Camera for Surveys (ACS), and the Wide Field Camera 3 (WFC3) between March 2000 and August 2009.

🙂 I hope you all had lots of fun yesterday while celebrating the coming of 2011. Apparently humans weren’t the only ones playing with fireworks… Here is a picture of some cosmic fireworks. This galaxy was nicknamed the “Fireworks Galaxy” for good reason. Over the last century, at least nine supernovae were discovered in that galaxy. By comparison, the average rate for supernovae in the Milky Way is about 1 per century. A supernova can be brighter than whole galaxies for some time after the explosion. That’s some fireworks! This beautiful spiral galaxy, also known as NGC 6946, is located 10 million light-years away in the constellation of Cepheus. It…
