Aside from the actual science, I am learning that 1) Copenhagen can be quite cold in the summer and 2) that the natives here are quite friendly. More than once people on the street have stopped to help me find my way. And the streets are full of people -- walking, riding bikes, taking buses. It seems to be a fitting place to have sessions on urban planning. From what I can see, Copenhagen has adopted some of the better ideas. After a morning of biology, I went for physics and aerospace in the afternoon. The subject was the Google LunarX prize.  To get the $20 million, the winning team will…
Tell me, O muse, of that ingenious ship which will peer far and wide... The European Space Agency is being very sensible and mapping out its schedule for large and medium science missions for the medium term, under the Cosmic Vision program. In particular, the first of the large missions, L1, has been chosen and is JUICE, Jupiter Icy Moons Explorer - a Jovian orbiter scheduled for launch in 2022, to study the three outer Galilean Moons. Athena The other mission concepts which competed for the L1 mission slot were Athena, a reformulated large X-ray observatory - Athena is revisit of the…
“At the last dim horizon, we search among ghostly errors of observations for landmarks that are scarcely more substantial. The search will continue. The urge is older than history. It is not satisfied and it will not be oppressed.” -Edwin Hubble While new discoveries are made about the Universe, a new explorer finds its way on a foreign world, and the world bids farewell to a legend, my old favorite -- the Hubble Space Telescope -- keeps amazing us all.

"Everyone is a moon, and has a dark side which he never shows to anybody." -Mark Twain Back before the telescope was invented, Saturn was known as the Old Man of the Skies. The slowest-moving of the naked-eye planets, it's the only one that would reliably be in nearly the same location, year after year. You can find it all summer, after sunset, by following the "arc" of the handle of the big dipper all the way until you run into the brightest northern-hemisphere star, Arcturus, and then speeding on to the very bright Spica. Saturn is right next door. Image credit: EarthSky.org. But…
Official word on the IXO x-ray mission now, with rumours from Europe on what the European Space Agency has in mind. LISA must be rebranded, quick! IXO News "This is an update on the discussions with the European Space Agency (ESA) at the recent ESA-NASA bilateral meeting. ... ESA has ended consideration of IXO and the other concepts as partnerships at the scale proposed in the New Worlds New Horizons decadal survey (NWNH) and EJSM/Laplace in Visions and Voyages for Planetary Science. Instead, ESA has begun a rapid definition effort that includes the formation of a new science team (to be…
Idunn Mons on Venus with recent emissivity data from the Venus Express overlaid on the topography, suggesting recent lava flows. NASA released images today that suggest that the surface of Venus has experienced some relatively recent volcanic events (geologically speaking). By examining the surface in infrared, the Venus Express, launched by the European Space Agency (ESA) has found that three spots on the surface exhibit signs of recent volcanism. The long-and-short of the research lead by Dr. Sue Smrekar of JPL is that a number of Venutian lava flows (shown above on Idunn Mons) show less…
The annual Entomological Society of America meeting is next week (Dec 13-16) in Indianapolis.  I'm giving two presentations- one on Pheidole and one on Heterospilus- that the sadistic conference organizers scheduled for the very last day when no one is around.   So if you are attending and happen to miss your flight out, consider heading back to the conference center to catch my talks. The 2009 meeting will be a good one for we social insect people.  I am especially looking forward to the Hoelldobler & Wilson symposium, but the rest of the program is packed with goodies. Also. …

The photographer writes; The Alabama beach mouse ekes out a living on a 14-mile stretch of the state's Fort Morgan Peninsula, where its dune habitat is fragmented by construction and lit up at night. Habitat saved under the Endangered Species Act (ESA) prevented these nocturnal mice from going the way of the dodo. Joel Sartore has shared some of his work on this blog…

Image: Joel Sartore/National Geographic [larger view]. The photographer writes; They survived the Ice Age, but condors barely held out against Homo sapiens. Many of these scavengers were shot or poisoned by fragments of lead left behind by hunters. In 1985 just nine wild birds remained. Captive breeding and reduced use of lead ammunition have brought the species back. Joel Sartore has shared some of his work on this…
