“When you fall asleep tonight, just remember that we lay under the same stars.”
Taken on my penultimate night in the PH. Ngayon lang ako nagkalakas ng loob tignan pics ko nun huhu. I miss everyone already. Sana miss nyo rin ako. Choz. Hirap maging clingy
Have you ever seen a jet fly overhead at a supersonic speed? If so, you may have heard a loud “boom" as it passed by. Did it explode? Nope! You can still see it flying. Then what was that sound? It was a sonic boom.
A sonic boom is a loud sound kind of like an explosion, caused by shock waves created by any object that travels through the air faster than the speed of sound. Sonic booms create huge amounts of sound energy that creates what you see in the pictures above!
Whirlpool galaxy also known as M51 is a famous grand design spiral face on galaxy located in constellation 'Canes Venatici' at a distance of 30 million light years from earth. It has an apparent magnitude of 8.4 and can be seen through a medium size telescope from dark sky locations.
The Whirlpool also has a faint companion galaxy NGC 5195 it can be seen interacting with this, the hubble images shows this dwarf galaxy is passing behind the m51...the tidal interaction of the galaxies has considerably enhanced the spiral structure of m51, astronomers believe its giving birth to stellar nurseries.
When galaxies collide their stars do not crash with ones and the others.
Instead the strong tidal forces disrupt the structure of galaxies and many stars are ejected into outer space. The dust we see in galaxy structure consists many star systems expelled which are doomed and lost in the emptiness of space and they are moving further away fron their parent galaxies.
Both galaxies will eventually merge but it will take another few passes for the merger to be complete.
This is the Jewel Box Cluster. It's a photo that is probably not particularly exciting for anyone but me! Although you can clearly see I need to collimate my scope, I have coma and also some star trails, this is the first photo I took after FINALLY learning to set up and align my scope -all on my own-! At last week's Star Party I was so frustrated I honestly thought this day would never come. I think this hobby is slowly teaching me the true meaning behind "if you want to be good at something, you have to be willing to be bad at it first". I'm over the moon (pun intended. Haha!) that I was finally able to understand the setting up process. Still heaps to learn!
How is it that every time I look at the clock while at work it's only been 4 minutes, but every time I look at the clock while making tea it's been an hour.
