Ever wondered what it looks like when two galaxies collide? 🌌

What you're looking at is the Whirlpool Galaxy (Messier 51), a spectacular cosmic collision of two galaxies across the vastness of space. Located around 23 million light-years away, M51’s spiral arms are a spectacle of stars, dust, and gas, all swirling under the gravitational pull of its companion galaxy, NGC 5195. This celestial interaction has been ongoing for millions of years, slowly pulling these galaxies together in an epic galactic merger.

As the galaxies interact under their mutual gravitational pull, we get a glimpse into the fascinating processes that drive galaxy formation and evolution. What's even more mind-blowing? The light you're seeing has been traveling for millions of years, offering a snapshot of the universe long before humanity was even a thought.

To witness this cosmic dance from a small corner in the mountains of San Diego, is a humbling reminder of just how immense and awe-inspiring the universe truly is. 🌌

Comet 2023 A3 (Tsuchinshan-Atlas) rising above the eastern mountains of San Diego, California. After seeing all the hype and clickbait on the "Comet of the Century", I had to see this visitor myself. Yes, it was visible without equipment. Seeing this giant streak of light across the horizon with the warm colors of the sunrise painting the sky was truly neat. But it really wasn't as impressive as C/Neowise in 2020. Maybe those on the Southern equator were able to witness a more impressive show since it is very low on the horizon for us. Comet-gazers in Chile, for example, were able to easily see the comet in the night sky making it appear even more bright.

Stay tuned for mid-October. There will be another opportunity to see this cosmic visitor right after sunset instead of sunrise! Maybe I'll host some type of event...

Spent the night out in the mountains waiting for a comet to rise above the horizon this morning ☄️ although I did get to see it with the naked-eye, I don’t know if it’s as impressive as the comet we saw back in 2020 (Neowise). The window to see C/2023 Tsuchinshan/Atlas A3 is VERY small because as soon as it rises above the horizon, the sun is also rising making the sky brighter.

Right now the comet is going around the sun and will come out the other side in mid-October. This is when it’ll be easily seen after sunset 🌅

Have you ever seen a comet before?

While I waited for the comet to be visible, I was able to capture a few hours of data on the Pleiades star cluster and the Andromeda Galaxy 🌌 results coming soon this week!

Saturn and Jupiter brought to you by your favorite Astronerd 🔭

If you could safely fly near these gas giants and witness their gargantuan features, which one would you prefer to see? 🚀

Heart & Soul Nebula ✨🌌

The nebula pair are located in one of my favorite constellations, Cassiopeia! Several cosmic structures are hidden within so make sure to point your telescope here next time. Photons from these clouds of energized gas travel for almost 7,000 years to reach us. Make their trip worth it and catch them! 🔭👀🚀

Captured this the night of Sept. 1st, 2024.

Saturn during the night of August 11th, 2024🔭

A lot of room for improvement but not bad for my 1st attempt this year.

Imaged at 5000mm focal length using a 2.5x Powermate

Will try again tonight! 🤞🏽🌌🪐

Make sure to not miss these dates in 2024! 🔭
~September 8th is Saturn's Opposition
~December 7th is Jupiter's Opposition
These are the days when each planet appears brighter and larger to us on Earth. This effect is a result of Earth traveling around the sun once a year and passing by other planets also traveling in their orbits.

Here is a composite of 2 images I created from data collected in the summer of 2022. A telescope with a focal length of 2,500mm was used. To better imagine the scale of what we are looking at, the moon would appear to be around 40 times wider than Jupiter if seen in our night sky!

Stay tuned for the next stargazing event if you're trying to see Saturn, the Milky Way galaxy, the craters on the moon, or a far, far, away galaxy 👽🌌

We are seeing photons that traveled for 7,000 years before they were absorbed by my telescope. The Eagle Nebula and the Pillars of Creation can be easily seen here after only 45 minutes of data collection 🌌🔭

San Diego might not have the clear skies that Arizona, Utah, and Texas have but we do have mountains. Although light pollution still gets in the way, driving my equipment to almost 5,000 feet in elevation really makes a difference when imaging the universe from Mount Laguna 🏔️

Did you know…?
Out of the 24 astronauts that flew to the moon during the Apollo program, 12 flew around the moon and 12 men landed/walked on the moon.

Here are 4 of the 6 landings that had boots on the moon 🌙 🚀 Can you see the footsteps left behind? 🤭

"I have loved the stars too fondly to be fearful of the night"

This is a picture captured close to 2am. Although it is way past midnight, the moon was bright enough to illuminate everything! Makes me feel safe when I can see my surroundings. Moonless, dark nights are the ones 💀🌠

Anyways, this is an example of what the Stargazing events will be looking like this spring/summer season!🙏🏼 make sure to share with a friend so you don't miss out on a unique stargazing experience in San Diego county!
