There's a somewhat curious article on the German IT news portal Heise in which the German GLPX team PTScientists is basically blaming both or alternately SpaceX and the XPrize Foundation for their loss in the race.

They are saying that the delays from the launch pad explosion caused them to miss the 2017 deadline, but what I think is very strange here is that they announced in November 2016 that they had a contract through Spaceflight, the same company that SpaceIL is working with. At that time, it wasn't even clear which launch provider they would be using.

But what I found really infuriating was the last paragraph of the article, in which one of the PTScientists team members says (and this is a literal translation): "Robert Böhme estimates the chances of the other teams as rather small, since their technology has hardly been tested at all or key components are still missing. He does acknowledge that the Indian team has good prospects for a successful lunar mission because it is supported by the Indian Space Agency ISRO, but even this could take a couple of years."

There's also a remark that the Google Lunar XPrize will be "silently shut down anyway" in 2017 because "ten years are more than enough". That's misleading at best, because the competition has now basically run its course as planned!

What a disappointing behaviour. PTScientists literally think they're better than everyone else, claim that the GLPX is a failure and that the other teams are incompetent. I expected better from them.

Next year's state of the union address should prove to be very interesting I think

How's this for nightmare fuel: astronomers have apparently found a rogue object flying away from the center of its host galaxy at a speed of >2,000 km/sec. Is it a rogue planet? Pffft. Maybe a runaway star? Small fry. Try a 1-billion solar mass black hole! Now we're cooking w/physics!

The video describes what may be the best candidate yet observed of a quasar flung away from the two merging galaxies as a result of a significant difference in the masses of the two original galactic cores. The paper referenced was accepted for publication by the journal Astronomy & Astrophysics back in January of this year, & may be found in its entirety at either of the links below:

I've uploaded the video from our Summer Lecture (late decision to do so, the reason for low quality). On the 10th of March 2017, We celebrated the 40th anniversary of the co-discovery of Uranus’s rings. This was a massive achievement for Western Australia, the Perth Observatory and its staff as the results they delivered made WA an important astronomy outpost to the scientific community.

Former Perth Observatory astronomer Peter Birch, who was an observer on the night of the discovery, is the speaker and talks about the lead up to the event and the explain how the Perth Observatory helped discover Uranus’s Rings.
