Titan has always stood out as the only moon in the solar system with a substantial atmosphere. In fact, the surface pressure on Titan is 50 percent greater than the pressure on Earth.

The atmosphere of Titan appears similar to that on Earth about 3.5 billions years ago before life appeared.

After a seven-year journey on board the Cassini spacecraft, ESA’s Huygens probe reached Titan’s surface, marking the most distant landing ever achieved by a spacecraft. During the descent its cameras collected data on the dense atmosphere and took the first ever images of the surface.

These revealed an extraordinary world with lakes, islands and signs of erosion similar to those that shape our planet, confirming that liquid methane once flowed there. Methane on Titan is found in liquid form and not as a gas due to the intense pressure and cold temperatures, about –180° C.

"Is that the little Dipper?" No, sorry. It's just the seven sisters. 😝

This is a process of data I've collected over the course of a couple months here and there. Approximately 6 hours of data consisting of 30s, 60s, 180s, and 240s exposures. Not each night was the best seeing and I live in Bortle 6 skies.

I redid this image to help ease of the artificial diffraction spikes I made in the last edit. They can get a little crazy with stretching.

Do you remember how old you were when Apollo 11 made a successful lunar landing on July 20, 1969? 🚀🌑🌑🌑🚀

Astronauts Neil Armstrong, Michael Collins, and Buzz Aldrin were all aboard the spacecraft.🧑‍🚀🧑‍🚀🧑‍🚀

Andromeda is one of our closest neighbors and is visible to the naked eye in darker skies. It's been a long ride to get an image I am pretty happy with in terms of detail and quality. I've spent quite a a bit of time over multiple attempts at processing this one since starting AP a few years ago. Always adding data I acquire to my stacks and attempting to reprocess better than the last. The red is areas of ionized hydrogen alpha gas excited by the energy of nearby stars.

Everyone by now has heard of the impending collision between our galaxy and Andromeda in around 4 billion years, but what isn't talked about much is this isn't the first collision we've had in our Galaxy's lifetime. Nor will it be the next collision in our future. The Large Megellanic Cloud is said to be heading our way and will meet with us in approx. 2 billion years. Our central supermassive black hole will grow by as much as 8 times it's current mass and, with the exchange of stars, we will look less unique as we do now and more like the majority of other galaxies.

Gaia Enceladus was our first major collision and actually shaped us into the galaxy we look like today. This collision took place around 2 billion years ago when the Milky Way was a stubby disk that slowly took on its current shape after the collision flug out stars and created its halo. After some time parts became unstable and collapsed into a bar like shape that eventually created a new thin disk and subsequently the Milky Way transformed into the galaxy we call home today.

Once Andromeda and the Milky Way collide both galaxies will lose their spiral shape and form one spheroidal elliptical galaxy. Most of their star forming gases will be lost during the merger, leaving a galaxy with no new young stars to replace the older stars. The supermassive black holes will eventually merge as well to created an even more massive one. But of course we won't be around for any of this, at least not on planet Earth, anyhow, since the sun will have started it's end of life party and scorched our cozy home.

Recently, i bought 8$ 8x mobile "telescope", and now trying to make some photos with it. That's 90 stacked shots in AutoStackkert3! edited in GIMP and Snapseed.
