_____________________________
The Large Magellanic Cloud (LMC) supernova remnant N 49 as seen in this Hubble image is only a few thousand years old. However, the Earth's distance to the LMC is 160,000 light-years, meaning that it takes 160,000 years for the light from the LMC to reach Earth. Although the remnant is from a massive star that died in a supernova blast thousands of years ago, by our Earth calendars the blast actually occurred over 160,000 years ago.
Most of the elements of our bodies were formed in stars over the course of billions of years and multiple star lifetimes.
Planetary scientist and stardust expert Dr Ashley King explains.
'It is totally 100% true: nearly all the elements in the human body were made in a star and many have come through several supernovas.'

A fiddler crab with mating colors, shuffles along on a bluish muddy backdrop. His little eyes are up above him on stalks, but the deep indentations in the front of his carapace sure look like big grey alien eyes!
(a "Macro Mondays" submission, theme "Zodiac." I chose Cancer, the crab. HMM!)

Star Trails over Mt. Shuksan Range | Press L to view in lightbox (must see large!)
This shot was taken during the same hike we did at Lake Ann, North Cascades. I didn't realize I got a portion of the celestial equator with this shot -- you can see some of the star trails going to the opposite direction. Over to the top left is a faint Perseid meteor.
Exposure: 1870 seconds (single exposure)
Aperture: f/2.8
Focal Length: 24 mm
ISO Speed: 200

The Milky Way glowing brightly in the night sky, revealing countless stars from Blayney, Central West, NSW, Australia.

Note: We have white sand here and it is very warm (well, the color was altered also, it does look like snow now that I look at it...)
My first foray into the art of astro-photography.
Me and my partner Paulina drove to the fantastic Pinnacles Desert north of Perth and I was able to plan and capture my first attempts at this kind of work.
It is by no means perfect but I am still pretty proud of it. This is a blend of three exposures - one for the illuminated foreground, one for the shadow area behind and one for the night sky.
I have other plans for the reminder of this year but I intend to explore this kind of photography a bit more next year.
I'm sure others seeing this will think of a much more poetic caption!!
We are all SO happy to be seeing clear skies again after almost 2 weeks' of heavy gray smoke cover from forest fires that I can't stop looking UP!
This is part of my newest photo series named "Micro Galaxy".
My main goal was to create a space-like feel in macro scale.

Ayer volvÃamos de León de pasar en el pueblo el fin de semana. A la altura de Villanubla (Valladolid), ya anochecÃa, y desde el coche, el cielo nos regaló esta imagen: el reflejo de la luz del sol en una nube.
This is IC 1805, the Heart Nebula in the constellation Cassiopeia. Its nebulosity is extremely faint and not something you'd expect to be able to shoot in full moonlight from a light polluted suburban back yard. But I did thanks to a dual-band filter (L-Enhance) I used for the first time that blocks out all that unwanted light and transmits only the wavelengths specific to certain types of nebulas such as this one.
I used a 90mm f/6 triplet refractor equipped with a field flattener and mounted on an Orion Sirius EQ-G mount. The camera was a modified Canon 6D. Polar alignment, telescope focus, object acquisition, autoguiding, and exposure capture were all done from my iPhone using the ZWO ASIAir Wi-Fi device - an incredible piece of technology.
I combined 45 300s exposures at f/6, ISO 3200, for a total of 3.75 hrs exposure time. Images and calibration frames were stacked in Astro Pixel Processor and finished in Lightroom and Photoshop.
And just in time for Valentine's Day.

I've been planning this photograph for well over a year, but getting a night that has a half moon in the right place plus a cloudless night, plus a wind from the right direction has proved to be an utter pain. The stars aligned tonight.
This took one and a half hours to take, if it wasn't the coldest night of the year then it was certainly close!
