Space photos of the week: True colors shine through



The Cat Paw Nebula, located in our Milky Way, about 4,200 light-years from Earth, is extremely curious among astronomers. It's extremely active: the radiation of hot stars interacts with large molecules and dust particles, triggering this neon-green fluorescence. In addition, stars that form in the mist heat up gas that expands and appears as red "bubbles". Then there's the insane scale of the thing: this entire star factory is estimated at [809 bis 90 Lichtjahre] .

Hubble-icious: A combination of multiple shots that have been separated over the years provides one of the most colorful images of space Hubble has orbited in the last 20 years. Every spot, spot and vortex is an entire galaxy; some sit closer than others and are easy to spot, while others are faintly stained and blurred outside.

NASA's Juno has opened our eyes to a new Jupiter. Look at this picture with its mass of white clouds above left: these are high-altitude clouds that swirl far above the other atmospheric layers. You can even see the shadows that are directed at the underlying areas, making this color-enhanced photo almost three-dimensional.

The Moon Titan is the only one in our solar system that has its own atmosphere and has rivers and lakes to boast of methane and ethane. Titan looks like a piece of delicious candy in this infrared image, but we see surface features, including mountains and regions covered in ice. This global map, the most detailed view of the Saturn moon so far, was created using Cassini data from 1

3 years ago (VIMS instrument for visual and infrared mapping spectrometer).

Wind currents move grains of sand like the winds in the vast deserts of the earth. This region is called Lyot Crater. The NASA's HiRise camera on the Mars Reconnaissance Orbiter is so advanced that it can select very small and fine surface materials – in this case, a mixture of dust and sand. The sand is also a unique composition for this area.

Love Your Neighbor: In 2015, NASA released a stunning panoramic photo of the Andromeda galaxy, which is rich in detail thanks to Hubble. Astronomers estimate that they can locate more than 100 million stars at this resolution. (NASA says the feat resembles a snapshot of a beach and the resolution of single grains of sand.) And, while Andromeda is about 2 million light-years from Earth, our Milky Way and Andromeda are fatefully colliding with each other over time and creating a new connected one galaxy. At the moment you can see Andromeda on a clear night with a home telescope.
