Messier 51, The Whirlpool Galaxy, imaged from my backyard in South Phoenix. 04052022.
This is a reprocess with Pixinsight.
The object that seems attached to a spiral arm of M51 is another galaxy, NGC5195. It has interacted with M51 enough to distort that spiral arm.
The universe is full of molecules. But how and when do these transform into life?

I Zwicky 18, is an irregular dwarf galaxy located 59 million light-years far. In this wonderful JWST image we can see two bursts of star formation at its heart, surrounded by gas, winds and radiation from hot & young stars: https://t.co/GCHQGEG1gi
8 months down, 4 to go!
On this week’s #HWHAP, the CHAPEA crew checks in on their eighth month in a Mars simulated habitat and a NASA biostatistician discusses the process of analysis, interpretation, and presentation of scientific data. https://t.co/pkF0zIhL3s
Transforming deep space communication... that's pretty innovative! 📡
JPL was recently named one of the "Most Innovative Companies in Space for 2024" by Fast Company, which highlighted the Deep Space Optical Communications (DSOC) experiment riding aboard #MissionToPsyche.
M81 is a grand design spiral galaxy located nearly 12 million light-years away. It contains over 250 billion stars.
The Spitzer Space Telescope took this stunning infrared image of M81, combining data from various wavelengths and converting it into a composite mosaic.
Mercury isn’t in retrograde, but these photos are retro. ✌️
50 years ago, Mariner 10 conducted a close flyby of Mercury. It was the first spacecraft to study the planet, and in 3 flybys, found the planet had a weak magnetic field and lacked an atmosphere or ionosphere.
.@LunarLoral works on an experiment studying various types of crystals in microgravity. This research aims to improve medications and test the efficacy of the PIL-BOX DMC hardware, an in-space laboratory specifically used for enhancing biological crystals.
At 17,000 light-years away, the furthest exoplanet ever discovered, named K2-2016-BLG-0005Lb, is a planet much like Jupiter. Using a technique called gravitational microlensing, this gorgeous gas giant exoplanet was found to have a similar mass and orbital distance as Jupiter.
Galileo's Europa
Looping through the Jovian system in the late 1990s, the Galileo spacecraft recorded stunning views of Europa and uncovered evidence that the moon's icy surface likely hides a deep, global ocean. Galileo's Europa image data has been remastered here, with improved calibrations to produce a color image approximating what the human eye might see. Europa's long curving fractures hint at the subsurface liquid water. The tidal flexing the large moon experiences in its elliptical orbit around Jupiter supplies the energy to keep the ocean liquid. But more tantalizing is the possibility that even in the absence of sunlight that process could also supply the energy to support life, making Europa one of the best places to look for life beyond Earth. The Juno spacecraft currently in Jovian orbit has also made repeated flybys of the water world, returning images along with data exploring Europa's habitability. This October will see the launch of the NASA's Europa Clipper on a voyage of exploration. The spacecraft will make nearly 50 flybys, approaching to within 25 kilometers of Europa's icy surface.
