Criminal charges have been filed against a German rabbi for performing circumcisions.

A doctor from Hesse filed a criminal complaint against Rabbi David Goldberg, who serves in the community of Hof, in Upper Franconia (northern Bavaria), according to the Juedische Allgemeine weekly newspaper. The chief prosecutor of Hof confirmed that charges had been filed against the rabbi. The charges are based on the controversial decision of a Cologne district court, which ruled in June that circumcisions for religious reasons constitute illegal bodily harm to newborn babies.

The article does not tell us anything about the doctor who filed the complaint. I wonder what that doctor’s motives are.

Monday’s successful spacewalk by two Russian astronauts preps ISS for the arrival of a new Russian module.

Monday’s successful spacewalk by two Russian astronauts has prepared ISS for the arrival of a new Russian module.

I should have posted a link about this spacewalk earlier. What is important however is that the Russians continue to move forward, though slowly. And they continue to come up with simple solutions to problems, such as the extra layer of shielding for the living quarters on ISS, installed during this spacewalk.

Astronomers have found what they believe is the first evidence of a planet consumed by its star as the star expanded and aged.

Astronomers have found what they believe is the first evidence of a planet consumed by its star as the star expanded and aged.

Sadly, for those of you out there who like the idea of watching planets getting destroyed, the event happened a long time ago, and all the astronomers have is circumstantial evidence that is most likely explained by such an event.

Astronomers have now confirmed 41 new exoplanets, first pinpointed by the Kepler space telescope

Astronomers have now confirmed 41 new exoplanets, first pinpointed by the Kepler space telescope.

One paper, by Jiwei Xie at the University of Toronto, confirms 24 new planets in 12 systems. Another study, by Steffen and his colleagues, confirms 27 planets in 13 systems. Five of the systems, and 10 of the planets, are the same in both papers. All in all, the new research adds 20 new planetary systems to the 47 that Kepler had previously confirmed, marking a more than 40 percent increase.

Among the Kepler candidates are five Earth-sized planets in the habitable zone, according to the vidoe at the link. However, this announcement does not tell us if any of those candidates were confirmed by these two papers.

NASA has announced its next planetary mission, a lander to Mars that will drill down thirty feet into the planet’s surface

NASA has announced its next planetary mission, a lander to Mars that will drill down thirty feet into the planet’s surface.

Though exciting in its own right, this mission is far less ambitious than the two missions which competed against it, a boat that would have floated on the lakes of Titan and a probe that would have bounced repeatedly off the surface of a comet. I suspect the reason this mission was chosen is the tight budgets at NASA, combined with Curiosity’s success which makes it politically advantageous to approve another Mars mission. As the NASA press release emphasized,

Scaled Composites has posted the results of its latest test firing of the rocket motor for SpaceShipTwo.

The competition heats up: Scaled Composites has posted the results of its latest test firing of the rocket motor for SpaceShipTwo.

Though the test is dated August 9, more than a week ago, I expect the number of engine tests to go up in the coming months as the company works toward the first powered flights of SpaceShipTwo.

On August 13, 2012, Voyager 2 became the longest-operating spacecraft in history, finally topping Pioneer 6, which was launched on Dec. 16, 1965, and sent its last signal back on Dec. 8, 2000.

On August 13, 2012, Voyager 2 became the longest-operating spacecraft in history, finally topping Pioneer 6, which was launched on Dec. 16, 1965, and sent its last signal back to Earth on Dec. 8, 2000.

And Voyager 2, along with its partner Voyager 1, are still working, and engineers hope they will still be working for another eight to twelve years, enough time for them to leave the solar system and enter interstellar space.
