All the modern films taken at night usually capture this celestial course from a fixed point of the Earth. Thus you will most likely watch the moon or the milky way make their way across the firmament. In the Northern Hemisphere, it seems to move from left to right, and the opposite in the Southern Hemisphere. Nonetheless have you ever seen a film where the night sky is fixed and the Earth moves instead? Well, now you have!That was the whole point of this short time-lapse film that I dubbed ‘Orbem Terræ’, or orbiting Earth in latin. The goal is to bring a whole new perspective on how we actually move against the background sky! In this manner, some of the clips give a very cool effect where you almost feel like you’re on the International Space Station lokking down at the Earth. This ‘floating’ effect is admittedly unsettling though, as if we will fall into the abyss of the universe. However only now can you appreciate the true movement of rotation of our planet in the solar system. Some of the clips are also tilted, reversed and rotated on purpose to accentuate the effect, so much that sometimes, you have no clue what is up and what is down! It’s especially true for the scenes featuring water reflection!

To achieve this particular effect, it actually not rocket science. There exist simple devices that, if set in the right way, can follow and track a particular point of the sky by compensation for the rotation of the Earth. By mountain your camera on top of those ‘tracker’, you can now have a fixed sky, a rotating Earth effect, and some advantages as the cherry on top: more details in the night sky objects!

This short film is actually a compilation of all the best tracked shots I have acquired during the past 4 years. After all my different movies, I’ve been asked a number of times to put together this compilation, so here you go! They were taken all over the globe from Europe to South America, Africa to North America. It features some of the most detailed astrophotography sequences on the market for this quality output, including some never-seen-before ones! “ – Adrien Mauduit

Hunter’s Moon 2019


In honour of the full Hunter’s Moon this weekend – timelapse from Adrien Mauduit at Night Lights Films – https://www.youtube.com/channel/UCC0CLzCpM6nuLSAi1JNBjkA

Hunter’s is an autumn moon, the first full moon of fall following the Harvest (full moon closest to the fall equinox) moon. https://earthsky.org/tonight/full-hunters-moon-from-dusk-till-dawn?utm_source=EarthSky+News&utm_campaign=45a5e032e7-EMAIL_CAMPAIGN_2018_02_02_COPY_01&utm_medium=email&utm_term=0_c643945d79-45a5e032e7-393970565

Black Hole Visualization


This week NASA’s Goddard Space Flight Center released a black hole visualization. Jeremy Schnittman, astrophysicist specializing in computational modeling of black hole accretion flows enlisted computer software to animate black hole glory. From https://www.nasa.gov/feature/goddard/2019/nasa-visualization-shows-a-black-hole-s-warped-world

Viewed from the side, the disk looks brighter on the left than it does on the right. Glowing gas on the left side of the disk moves toward us so fast that the effects of Einstein’s relativity give it a boost in brightness; the opposite happens on the right side, where gas moving away us becomes slightly dimmer. This asymmetry disappears when we see the disk exactly face on because, from that perspective, none of the material is moving along our line of sight.

Closest to the black hole, the gravitational light-bending becomes so excessive that we can see the underside of the disk as a bright ring of light seemingly outlining the black hole. This so-called “photon ring” is composed of multiple rings, which grow progressively fainter and thinner, from light that has circled the black hole two, three, or even more times before escaping to reach our eyes. Because the black hole modeled in this visualization is spherical, the photon ring looks nearly circular and identical from any viewing angle. Inside the photon ring is the black hole’s shadow, an area roughly twice the size of the event horizon — its point of no return.

“Simulations and movies like these really help us visualize what Einstein meant when he said that gravity warps the fabric of space and time,” Jeremy Schnittman, who created the images at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, said in a statement.

The black hole’s extreme gravity alters the paths of light coming from different parts of the disk, producing the warped image. “What we see depends on our viewing angle,” NASA said.

Timelapse Of The Future


From melodysheep –

We start in 2019 and travel exponentially through time, witnessing the future of Earth, the death of the sun, the end of all stars, proton decay, zombie galaxies, possible future civilizations, exploding black holes, the effects of dark energy, alternate universes, the final fate of the cosmos – to name a few.

This is a picture of the future as painted by modern science – a picture that will surely evolve over time as we dig for more clues to how our story will unfold. Much of the science is very recent – and new puzzle pieces are still waiting to be found.

To me, this overhead view of time gives a profound perspective – that we are living inside the hot flash of the Big Bang, the perfect moment to soak in the sights and sounds of a universe in its glory days, before it all fades away.  Although the end will eventually come, we have a practical infinity of time to play with if we play our cards right. The future may look bleak, but we have enormous potential as a species.

Night Skies And Petroglyphs


From Harun Mehmedinovic and Gavin Heffernan at https://vimeo.com/357143587 – Ancestral Nights. Filmed for Skyglow Project, a crowdfunded endeavor illustrating effects of light pollution on dark skies. Lose yourself in night skies and petroglyphs….

Carvings, structures and petroglyphs captured in this video represent ancient observance of night skies by Native Hawaiians, Paiute people of California and Puebloans of the Southwest.

Concentric white circles filling the sky over large rock with symbols carved into it.

“These petroglyphs and structures reflect the long standing interest in ancient astronomy which grew stronger as many of the tribes went from the hunter-gatherer to the agrarian societal orders. From references to the sun carved in the rock, and interest in using the sun to predict seasons (entire buildings built to serve as sundials and calendars, a critical element in the farming communities) to those of 13 moons (lunar annual calendar), to carvings of stars and constellations, interest in celestial bodies is ever present across the indigenous communities of the United States.” – Harun Mehmedinovic

Northern Hemisphere Aurora Alert


As I write, streams of solar wind advance at 594.5 Km/second. Commanded by CH58+, a impressive coronal hole poised to deliver rare auroral punctuation as far south as Washington State, Idaho, Montana, Michigan and Minnesota.

Auroras happen when electrons energized by acceleration collide with Earth’s upper atmosphere. Acceleration allows energized electrons to follow Earth’s magnetic field downward to the poles. Anywhere from 80 – 500 Km above Earth’s surface, electrons collide with oxygen & nitrogen atoms, spiking the atoms’ energy. Soon after, atoms relax to their former energy state – relaxation creates light known as aurora borealis. Initially light forms an arc from horizon to horizon, within a few hours arcs twist and sway in upper atmosphere wind.

A geomagnetic storm warning issued by NOAA, Space Weather Prediction Center, forecasts G1 (minor) activity August 31, increasing to G2 (moderate) September 1st as solar wind blows Earthward at 650 Km/second.

Its been years since space weather issued public alert of aurora over Greater Vancouver. Auroras are fickle, space weather makes no promises. That said, if you find yourself away from city lights with clear skies, don’t miss an opportunity for Aurora to wrap her arms around you. Once you meet Aurora, night skies become a source of wonder.
