In 2012, the Voyager 1 probe left our solar system. In 2018, Voyager 2 followed suit, and with it's instruments in better shape than Voyager 1's, scientists were able to track the probe's transition into interstellar space. Now, Voyager 2 has sent back it's first message from interstellar space. This is big.
The winners of the Royal Observatory Greenwich's Insight Investment Astronomy Photographer of the Year 2019 competition have been announced, and these photographs are out of this world (literally). We gathered the winning photos for each section so you didn't have to search for them, and they are A M A Z I N G. From insane details of the sun to long exposure photos of the stars moving in the sky, these photos are the best of the best when it comes to astrophotography. Look in awe and enjoy the beautiful universe and the incredible skill of these photographers. I tip my hat to them (especially the 11 year old photographer!).
This beautiful video is a look at a map of the Milky Way that was just released. The video description explains in detail about how the image was made:
This video takes a close look at a new image of the Milky Way released to mark the completion of the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL). The APEX telescope in Chile has mapped the full area of the Galactic Plane visible from the southern hemisphere for the first time at submillimetre wavelengths — between infrared light and radio waves — and in finer detail than recent space-based surveys.
The APEX data, at a wavelength of 0.87 millimetres, shows up in red and the background blue image was imaged at shorter infrared wavelengths by the NASA Spitzer Space Telescope as part of the GLIMPSE survey. The fainter extended red structures come from complementary observations made by ESA's Planck satellite.

For your frame of reference, there are approximately 200 to 400 billion stars in the Milky Way galaxy.
