Neptune Completes Its First Circuit Around The Sun Since Its Discovery
Neptune has just completed its first orbit around the sun since its discovery in 1846. And the Hubble Space Telescope has taken some pictures in celebration.

Gore Announces New Campaign and Worldwide Event to Re-energize Global Warming Hysteria
Al Gore has announced a new campaign “to broadcast the reality of the climate crisis and mobilize citizens to help solve it.”
And I ask: what the hell does a propaganda campaign tell us about the climate? The answer: nothing. Just because you say so, Al, does not make it so.
On another note, satellite data continues to show absolutely no warming for the past decade.

Global warming — or not
In the realm of science, when a computer model is contradicted by empirical observation, the model is deemed to have been refuted. Only in the field of global climate do purported scientists refuse to recognize that basic principle.
Ethane lakes in a red haze: Titan’s uncanny moonscape
Titan’s ethane lakes in a red haze.
So far, there are no recognisable signs of organic life. That’s not surprising: by terrestrial standards, Titan is a deep freeze with surface temperatures at a chilly -180°C. Yet Titan is very much alive in the sense that its atmosphere and surface are changing before our eyes. Clouds drift through the haze and rain falls from them to erode stream-like channels draining into shallow lakes. Vast dune fields that look as if they were lifted from the Sahara sprawl along Titan’s equator, yet the dark grains resemble ground asphalt rather than sand. It is a bizarrely different world that looks eerily like home. Or as planetary scientist Ralph Lorenz puts it: “our prototype weird-world exoplanet”.

More evidence dinosaurs were warm-blooded
A new study has found new evidence that dinosaurs were warm-blooded and active, unlike modern reptiles. Even more surprising,
“The dinosaurs appeared to be even more active than the mammals. We certainly didn’t expect to see that. These results provide additional weight to theories that dinosaurs were warm-blooded and highly active creatures, rather than cold-blooded and sluggish.”
Where to find life in the Milky Way galaxy
A paper published today on the Los Alamos astro-ph preprint website has attempted to model the habitable zones within the Milky Way galaxy. From the abstract:
We predict that ~1.2% of all stars host a planet that may have been capable of supporting complex life at some point in the history of the Galaxy. Of those stars with a habitable planet, ~75% of planets are predicted to be in a tidally locked configuration with their host star. The majority of these planets that may support complex life are found towards the inner Galaxy, distributed within, and significantly above and below, the Galactic midplane.[emphasis mine]
They took into consideration the hazard of supernovae for killing off planetary life, as well as other factors such as the where the necessary heavier elements would be available for producing planets.

Highest Water in a Decade Expected at Lake Powell
The highest water level in a decade is expected at Lake Powell by August.
Lake Powell’s rising water level is a result of the long and wet winter this year. An above-average snowpack, with late snows and unseasonably cold weather has lead to a slower melt than usual. As of May, the snowpack that feeds Lake Powell was 30 percent higher than average, with only 50 percent of the accumulated snowpack melted. [emphasis mine]
I thought Al Gore told us this wasn’t going to happen anymore.
A new image of Vesta from Dawn
Dawn continues to approach the large asteroid Vesta. Below is an image taken July 1st from about 62,000 miles. The image has a resolution of 5.8 miles per pixel.
Despite Vesta’s large size, 330 miles in diameter, it is nonspherical. This fact, combined with data that says it is differentiated with a core and mantle, suggests that it is the remains of a larger object that subsequently broke up.

More stupidity from the Center for Biological Diversity
The Center for Biological Diversity (CBD) today sued the Bureau of Land Management (BLM) in Colorado for allowing caving to take place at the annual convention of the National Speleological Society.
The CBD claims that human activity can spread white nose syndrome, the mysterious ailment that has been killing millions of bats across the eastern United States. To quote:
It is well documented that the fungus believed to cause white-nose syndrome, aptly named Geomyces destructans, can be spread on the clothes and gear of people visiting caves. Scientists strongly suspect that the disease is a recent import from Europe, likely transported by someone who visited a cave there and then came to North America.
To be blunt, this statement is an outright lie.

House proposes cutting NOAA by $103 million
More science budget news: The House today proposed cutting NOAA’s $4.59 billion budget by $103 million.
There already is some squealing about this (see the link above), but note that a $4.49 billion budget for NOAA would still be half a billion dollars more than NOAA’s 2008 budget, which is hardly what I’d call a draconian cut.
Another Iceland volcano appears about to erupt
Another Iceland volcano, Hekla, is showing signs that it is about to erupt.
The volcano, dubbed by Icelanders in the Middle Ages as the “Gateway to Hell,” is one of Iceland’s most active, having erupted some 20 times over the past millennium, most recently on Feb. 26, 2000. It measures 4,891-feet (1,491-meters) and is located about 70 miles (110 kilometers) east of Reykjavik, not far from Eyjafjoell.
House proposes to drop NASA’s budget to 2008 levels, eliminate Webb Telescope
The House today proposed cutting NASA’s budget back to 2008 levels while eliminating all funds for the James Webb Space Telescope.
As much as I’d hate to see the Webb telescope die, it has cost far more than planned, is way behind schedule, and carries a gigantic risk of failure. However, if I had a choice, I’d rather they cut the $1.95 billion for Congress’s homemade heavy-lift rocket, the program-formerly-called-Constellation. There is a much better chance that Webb will get completed, launched, and work, than there is for this improvised and impossibly costly Congressionally conceived rocket.
