    GPS, fast trains, cellphones, chemotherapy, internet and other wonders which make our life better and easier, were imagined & invented by people who believe in curiosity, observations and rational thinking, not by those who have a natural instinct for science.

    Improvised sidewalk astronomy in Mission this evening. This mailman loved seeing the Orion Nebula in the eVscope.

    And this "president" and his supporters are condemning an athlete for kneeling for our human right? Where is the outrage ? Will you find another great excuse for his behaviour? I am so tired of this...

    We took advantage of good sky conditions this weekend, and met with the Running Man & Horsehead Nebulae, together with Bode's Galaxy. (Bortle sky rating: 4).

    Thank you for everything you do for us and to restore social justice in this country. "Even if you’re not going to talk about the controversial part, at least talk about what he did on the field—which was electrifying."

    I was surprised by the positive energy in the room and the fact that most people who attended thoughts that L is very large and that intelligence and technology are natural evolution of life. 3/3

    After explaining the 5 unknown parameters, we asked the participants to give us their estimated values. We got <Ne>=.25 (min 01, max .7) <Fl>= .3 (.01, .7) <Fi>=.32 ( .00001, 1) <Fc>= .08 (1E-6, 1) <L> = 28E6 (1,000, inf) with Fp=1 & R=3 then <N> = 161,280 civilizations! 2/3

    Enough of this bullshit. I'm a Warren supporter, but I will gladly vote for Bernie Sanders in November if he wins the Democratic primary. This behavior isn't cute when Bernie supporters do it, and it's not cute when everyone else does it. The stakes are too high.

    How Michael Alexander had been charged and put behind bars for more than 3½ years for the gruesome murder of Leila Shreves even though there were no evidence and the real murderer could have been found by simply checking the police file history.

    The has become a party of irrational & dangerous people. Voting them out in your state is not enough. We must also financially and politically help all Democrats candidates elsewhere. Time to act now.

    Something is telling me that this flag is going to be back in 10 years or that it will be replace even sooner by the Scottish one. Very sad to see the UK turning their back to progress with the EU but it’s not over.

    M44, the Beehive cluster, in the constellation of Cancer. One the closest to Earth (600 lyrs away) and only 600 million years old. First observed with a telescope by Galileo in 1609 but known by the Greek as the Nephelion “little cloud”. Today observed with my eVscope

    Another environment activist killed. We need to fight back. Homero Gómez González, a former logger who became one of central Mexico's most prominent defenders of the region's monarch butterfly population, was found dead Wednesday.

    Hey amateur astronomers with eVscopes! Want to help us with a pilot program to find and better characterize exoplanets? Check out my blog post at for details. We may also be able to observe some targets of interest (TOI).

    Unpopular comment. It amazes me how some people are not afraid of pretending to be well-versed in a large number of topics at conferences. If someone asks me to talk about something unrelated to my research I will refuse and give the name of a colleague that could do it.
