Following Venus! On my way to a full circle, half way through. I followed Venus coming from behind the Sun to in front of the Sun (Evening Star). Now to wake up in the morning and follow Venus from in front of the Sun to behind of the Sun (Morning Star). Enjoy!

Tomorrow 25.03.2017 is the inferior conjunction of Venus with us Earth. It will pass the Sun for 8 days and will pop back the other side to climb the phases back to a "full" Venus behind the Sun.

We will be able to see Venus on the 07.04.2017 very near the Sun just before it rises (Elongation of the Sun of +20 degr.) It will complete a full circle (orbit) on new year day 01.01.2018 when it will be at superior conjunction from Earth.

Until then I will follow the planet Venus in the mornings and compile a picture similar to this one above, but on the right side of the Sun, i.e Venus the morning star.

Carnival of Space #500 here @ Links Through Space



This is a special edition of the Carnival of Space. As we hit the 500 mark, I want to thank everyone that has participated in the Carnival of Space through out the years. This initiative that has started almost 10 years ago is still going strong and is a pillar for Space news on the internet. 
So please join me here @ Links Through Space
for this epic edition of Carnival of Space #500.

We start the tour with Chandra X ray Observatory's blog, which has been a steady contributor of CoS.

 Now to a huge contributor of the Carnival of Space, the soul of the Carnival: Next Big Future.


A Massive commercial space push and a variety of new robotic capabilities could self supporting and rapidly growing space economy. Several companies will collectively be launching about 20,000 satellites over the next few years. SpaceX, OneWeb, Telesat, O3b Networks and Theia Holdings — all told the FCC they have plans to field constellations of V-band satellites in non-geosynchronous orbits to provide communications services in the United States and elsewhere. So far the V-band spectrum of interest, which sits directly above Ka-band from about 37 GHz to the low 50 GHz range, has not been heavily employed for commercial communications services. In orbit satellite servicing is being developed. DARPA and commercial ventures are looking at in orbit satellite repair and servicing. Rob Hoyt indicates that the challenges of effectively spreading off-world and colonizing the cosmos are overcome by making it easier to manufacture and assemble large systems and structures in space. This visionary physicist, engineer, and CEO is leading a team of scientists to overcome those challenges.Rob co-founded Tethers Unlimited Inc. in 1994, and built it into a space and defense research and development firm. He is now building a spin-off, Firmamentum, to commercialize in-space manufacturing. Rob has won more grants from NASA’s Innovative Advanced Concepts program than any other researcher.

Planetaria.ca is nothing of a dull place to get your space news. An regular contributor of the Carnival of Space. It is the place to be.



So here you have it!
All the thrills and excitements of the Astronomy/Space community this week.
The Carnival of Space #500

If you run a space/astronomy related blog and would like to get more awareness, participate in the Carnival of Space. Every week a different webmaster or blogger hosts the Carnival, showcasing articles written on the topic of space. It's a great way to get to know the community and to help your writing reach a wider audience. If you'd like to be a host for the Carnival or be part of the Carnival, please send an email to carnivalofspace@gmail.com.

2017 brings a new Youtube channel: LINKS THROUGH SPACE. Join me!



Links Through Sapce Youtube channel c2017


Hello everyone,
My name is Stefan Lamoureux, I am the president of the Astronomy Club Toutatis. I am based in Kustavi Finland. What I do is travel the world to visit the astronomy scene and write about it in my blog.
What is the astronomy scene? Well, it's visits to world class observatories, visits to local astronomy clubs, Expeditions to archaeoastronomical sites and of course meet on site with amateurs and professionals astronomers. A way to learn astronomy, but all over the globe. Have a look at my travels so far, visit my youtube channel and support me in my travels on Patreon.

Contributions like yours will boost our public outreach in astronomy, upgrade equipment, help cover travel costs and provide us with better educational materials to showcase.   

This time around, I ask your help to contribute to cost of my plane ticket to my next archaeoastronomical site: Egypt: An expedition in Egyptian ancient astronomy along the Nile river.
Play this video and see what it is all about.

En Francais: Comparaison entre les tailles des planètes du système TRAPPIST-1 et celles des corps du Système Solaire PARTIE 3


Sur ce diagramme figurent, à titre comparatif, les tailles des planètes nouvellement découvertes autour de la naine rouge TRAPPIST-1 ainsi que celles des satellites de Jupiter au sein de notre Système Solaire. Toutes les planètes détectées autour de TRAPPIST-1 sont de dimensions semblables à celles de la Terre.

En Francais: Comparaison entre le système TRAPPIST-1 et les lunes de Jupiter dans le Système Solaire PARTIE 2.


Sur ce diagramme figurent, à titre comparatif, les orbites des planètes nouvellement découvertes autour de la naine rouge TRAPPIST-1 ainsi que celles des satellites de Jupiter au sein de notre Système Solaire. Toutes les planètes détectées autour de TRAPPIST-1 se trouvent à plus grande proximité de leur étoile que la planète Mercure du Soleil. Toutefois, leur étoile étant beaucoup moins lumineuse, ces planètes se trouvent exposées à des niveaux de rayonnement semblables en intensité aux rayonnements que recoivent Vénus, la Terre et Mars dans le Système Solaire.
