Very hot link today between the orb of fire and the planet Mercury who go to 13 h 12. Michel Delmas, president of the astronomy club Gigouzac, offers the public to attend this hot date unusual through telescopes in Cahors (alleys Fenelon). Interview under the Sun exactly …
What do you advise Lotois to observe in good conditions the Mercury rendezvous with the Sun on Monday?
This phenomenon can not be observed with conventional binoculars. It is imperative to use a telescope with a solar filter. in Cahors, on driveways Fenelon (see box) we will make this material through which the public can then distinguish a small spot on the surface of the sun: Mercury passage. The observation will better understand the dimensions of the solar system. Mercury is 4878 km in diameter, while the Sun displays a diameter of 1.4 million kilometers.
What are for you the last great mysteries of Mercury? It is very enigmatic, even if Messenger probe has confirmed in recent years the presence of water as ice at the poles that never see the sun. There is speculation about its mass. Mercury’s core, made of iron, 42% of the mass of the planet. One of the Earth is only 17% of the total mass. Why Mercury has such a core will bring answers about the formation of the solar system.
Potentially habitable planets newly discovered outside our solar system.
what do you think?
I say it would be surprising that Earth is the only habitable planet in the universe while there other solar systems like ours with, close, planets that could possibly support life.
NASA and CNES are taking increasingly seriously extraterrestrial question. Do you believe in ET?
For me, this is part of the collective fantasy. Some testimonies unfounded contribute. For 10 years I observe the sky, I’ve never found inexplicable. Believe the visit of aliens remains a dream.
A recent “Made in USA” study yet imagines without affirm that life on Earth could be from an extraterrestrial colonization. Myth or reality?
It is possible, in fact, it is that life has arrived on Earth through certain molecules present in comets. So another source than our own planet. This assumption is actually possible.
Children have stars in their eyes when asked about the area. What is the meaning of your message to them?
First, it is the will to provide them with concrete evidence through observation carried the telescope. They will discover and understand a physical reality when they see through a small surface adjusted the telescope, the spot corresponding to the transit of Mercury across the sun. Seeing is understanding, provided to show some real facts in the instant they unfold. An observation is always magical, but totally true.
The Carrefour Association of Sciences and Arts, in connection with the astronomy club Gigouzac offers today, if conditions weather permitting, long transit of Mercury observing sessions before the sun 13 h 12 to around 18 hours in Cahors, on driveways Fenelon. The schools of the city and all the curious or passionate about astronomy are invited to attend this exceptional event where everyone will be initiated to astronomical observation.
