The Cat’s Paw Nebula, located in our Milky Way some 4,200 light years from Earth, sparks serious curiosity among astronomers. It’s extremely active: Radiation from hot stars interacts with large molecules and bits of dust, setting off that neon green fluorescence. In addition, stars forming inside the nebula heat up gas, which expands and appears as red “bubbles.” Then there’s the mind-bending scale of the thing: This entire star factory is estimated to be 80 to 90 light years across.

Hubble-icious: A composite of several exposures captured years apart yields one of the most colorful deep-space pictures made by Hubble in its 20-some years in orbit. Each speck, smudge, and swirl is an entire galaxy; some sit closer than others and are easily identified, while others further out are faintly tinted and hazy blobs.

NASA’s Juno has opened our eyes to a whole new Jupiter. Consider this image, with its cluster of white clouds at upper left: Those are high-altitude clouds swirling far above the other atmospheric layers. You can even make out the shadows cast on the areas below, making this color-enhanced photo seem almost three-dimensional.

The moon Titan is the only one in our solar system with its own atmosphere, and it’s got rivers and lakes of methane and ethane to boot. Titan looks like a piece of delicious candy in this infrared image, but what we’re seeing are surface features including mountains and regions covered in ice. This global map, the most detailed view yet of the Saturn moon, was made using 13 years worth of Cassini data from its VIMS (Visual and Infrared Mapping Spectrometer) instrument.

“Blue duuuuuune, you saw me standing alone.” Martian wind currents move grains of sand around, just like the winds do in Earth’s vast deserts. This region region is called the Lyot Crater. NASA’s HiRise camera on the Mars Reconnaissance Orbiter is so advanced that it can pick out surface material that’s especially small and fine—in this case, a mix of dust and sand. The sand is also a unique composition for this area.

Love thy neighbor: In 2015, NASA released a stunning panoramic photo of the Andromeda galaxy, rich in detail thanks to Hubble. Astronomers estimate they can pinpoint more than 100 million stars at this level of resolution. (NASA says the feat is akin to taking a snapshot of a beach and being able to resolve individual grains of sand.) And although Andromeda is some 2 million light years away from Earth, our Milky Way and Andromeda are, in time, fated to collide with each other, creating a new merged galaxy. For now, you can see Andromeda on clear a night with a home telescope.
