The law of unintended consequences strikes again! Nine environmental groups have found that the European Union’s plan to promote the use of biofuels over fossil fuels will actually damage the environment. Key quote:
The extra biofuels that Europe will use over the next decade will generate between 81 and 167 percent more carbon dioxide than fossil fuels, says the report.
China today released the first photos taken by Chang’e 2, its second lunar orbiter launched on October 1. More here, including one image.
What could go wrong? The American Geophysical Union is going to announce tomorrow a public campaign by 700 scientists to attack any skepticism of global warming.
More on the continuing eruption of Mount Merapi in Indonesia. Key quote:
The Volcano Mitigation and Geological Disaster Agency warned of worse in store as magma pushed towards the surface from depths of 6-8km, compared with a maximum 2km deep when the mountain previously erupted in 2006. “This is the scenario I dislike the most, because the deepest magma is pushing up now,” said the agency’s chief, Surono. “The eruptions haven’t stopped, the tremors are getting stronger and one big explosion could be the result. I’ve never seen it act like this. We don’t know what to expect.”
Cassini went into safe mode on Tuesday, November 2nd. At the moment engineers expect it to take at least another week to get the spacecraft back to normal.
Here are the first images of Deep Impact’s flyby of Comet Hartley 2. The first is a montage, the sequence in time going clockwise. The second is a close-up of the second image.
The feature that I find most intriguing is the narrow smooth waist of the comet’s dogbone shape. The whole thing looks almost like a piece of taffy that’s being pulled apart.
In a paper posted tonight on the Los Alamos astro-ph website, an astronomer is proposing an early warning system for asteroid impact. Key quote from the abstract:
This system, dubbed “Asteroid Terrestrial-impact Last Alert System” (ATLAS), comprises two observatories separated by about 100km that simultaneously scan the visible sky twice a night, and can be implemented immediately for relatively low cost. The sensitivity of ATLAS permits detection of 140m asteroids (100 Mton impact energy) three weeks before impact, and 50m asteroids a week before arrival. An ATLAS alarm, augmented by other observations, should result in a determination of impact location and time that is accurate to a few kilometers and a few seconds.
First close-up photos of Comet Hartley 2 reveal a space peanut.
What will the global warming scientists do? The new chairman of the House Science and Technology Committee calls for “strong oversight . . . in key areas including climate change, scientific integrity”.
Watch the Deep Impact flyby of Hartley 2 this instant (11:06 AM eastern)! The images are incredible. Update: The fly-by is over, but the live stream is still available (as of 11:30 am Eastern), showing some of the images taken. The comet itself is a peanut-shaped object about two miles long, with a jet of water coming out one end.
A do-it-yourself photo of the Sun that looks as good as any taken from space. And it’s art too!
NASA has completed a significant upgrade of its Deep Space communication system. These unheralded antennas and the engineers who maintain them make it possible for scientists to communicate with the far flung planetary probes in orbit around Venus, Mars, and Saturn, as well as the spacecraft visiting comets or traveling beyond the edge of the solar system.
Opportunity’s long journey across the desert plains of Mars to reach Endeavour Crater is now more than half completed. Below is the most recent mosiac of its view heading east towards the crater, with the crater’s rim visible on the distant horizon, still five miles away.
A UN conference in Japan today approved the extremely broad language that I had noted earlier this week, banning all “climate-related geoengineering activities that may affect biodiversity . . . until there is an adequate scientific basis on which to justify such activities.” You can read some reactions here. Key quote from the ETC group, a Canadian non-profit organization which supports the language:
The agreement, reached during the ministerial portion of the two-week meeting which included 110 environment ministers, asks governments to ensure that no geoengineering activities take place until risks to the environment and biodiversity and associated social, cultural and economic impacts have been appropriately considered. The CBD secretariat was also instructed to report back on various geoengineering proposals and potential intergovernmental regulatory measures.
If the broad language of this policy is accepted by the United States government, it will effectively shut down almost all new construction and development, as practically anything people do “may affect biodiversity.”
Scientists have discovered in China the first complete skeleton of an early ancestor of the gigantic sauropod dinosaurs.
Evidence of subsurface water has been found by the Mars rover Spirit at the location where the rover remains stuck.
Astronomers have discovered the most massive neutron star ever, twice the mass of the Sun and far heavier than any theory had ever predicted.
Buckyballs, or carbon molecules called fullerenes, have been discovered all throughout the Milky Way as well as in another galaxy.
Deadly monkey virus jumps from monkey to scientist.
