Gaia Sky is an open-source astronomy visualisation desktop and VR program with versions for Windows, Linux and macOS.It is created and developed by Toni Sagristà Sellés in the framework of ESA's Gaia mission to create a billion-star multi-dimensional map of our Milky Way Galaxy, in the Gaia group of the Astronomisches Rechen-Institut (ZAH, Universität Heidelberg).
The huge map has already helped changed our view of the galaxy in unexpected ways, according to its creators. In all, it catalogues more than 1.5 billion objects, a vast improvement on previous ...
The galactic coordinate system is a celestial coordinate system in spherical coordinates, with the Sun as its center, the primary direction aligned with the approximate center of the Milky Way Galaxy, and the fundamental plane parallel to an approximation of the galactic plane but offset to its north.
There have been detailed maps of the Milky Way before, but none quite so ornate as this. Researchers in the HI4PI sky survey have created a fine-grained map of our home galaxy using its most ...
The result isn't just a gorgeous image, but also an incredibly accurate look at our home galaxy. Along with that sky map, the ESA also released a really fantastic 360-degree video of the night sky ...
Figure 1.The observed structure of the Milky Way's spiral arms [1]. The Orion Arm, also known as the Orion–Cygnus Arm, is a minor spiral arm within the Milky Way Galaxy spanning 3,500 light-years (1,100 parsecs) in width and extending roughly 20,000 light-years (6,100 parsecs) in length. [2]
At first, it looks like a planet: dark, snow-speckled and slashed down the center by a deep red scar. But zoom in a little closer, and you realize you're looking at something much larger than a ...
