Two asteroids to fly past Earth
Collision alert! Two small asteroids are going to zip past the Earth this week, both passing closer than the Moon.
More evidence that the solar cycle is changing
A preprint paper published today on the Los Alamos astro-ph website shows further evidence of the decline in the strength of the Sun’s magnetic field over the past ten years. Extrapolated into the future, this data also suggests that the next solar maximum will be the weakest in 200 years, and that the solar maximum after that will have no sunspots at all. You can download the paper here [pdf].
Life on Mars?
New research now suggests that it was premature to conclude that Mars has no life, based on the data from the Viking missions to Mars in the 1970s. This is vindication for Gilbert Levin, one of the chief scientists for those missions, who had said so then and was subsequently pilloried for it.
Scientist fired at UCLA because research politically incorrect
UCLA has fired a scientist after 36 years because according to them, his “research is not aligned with the academic mission” of his department. In other words, his research uncovering flaws in the such politically correct subjects as secondhand smoke and diesel emissions is something the academic community at his campus cannot stomach. Key quote:
[The fired scientist] questions the science behind the new [California diesel] emissions standards, and he has raised concerns about the two key reports on which they were based – exposing the author of one study as having faked his credentials and the panel that issued the other study as having violated its term limits.
IPCC fail
Meltdown of the climate ‘consensus’. Key quote:
What does the best evidence now tell us? That man-made global warming is a mere hypothesis that has been inflated by both exaggeration and downright malfeasance, fueled by the awarding of fat grants and salaries to any scientist who’ll produce the “right” results. The warming “scientific” community, the Climategate emails reveal, is a tight clique of like-minded scientists and bureaucrats who give each other jobs, publish each other’s papers — and conspire to shut out any point of view that threatens to derail their gravy train.
IPCC needs reform
Better late than never. An independent academic panel has concluded that the IPCC needs reform.
Paper extolling the benefits from interstellar spaceflight
This guy is thinking ahead: a paper extolling the scientific benefits of interstellar space travel (published in a 2009 issue of the Journal of the British Interplanetary Society) was made available today on the Los Alamos astro-ph website. Fun quote from the abstract:
Significant benefits are identified in the fields of interstellar medium studies, stellar astrophysics, planetary science and astrobiology. In the latter three areas the benefits would be considerably enhanced if the interstellar vehicle is able to decelerate from its interstellar cruise velocity to rest relative to the target system. Although this will greatly complicate the mission architecture, and extend the overall travel time, the scientific benefits are such that this option should be considered seriously in future studies.
Active volcanoes on Venus?
Evidence continues to build that volcanic activity on Venus has occurred in the very recent past, and might even be going on today.
India announces instruments for its second Moon probe
India announced today the scientific instruments it plans for its second lunar probe, scheduled for launch in 2013. India is building the orbiter and Russia is building the lander/rover.
The influence of the Sun’s solar cycle on the atmosphere
Scientists have confirmed that the just ending low solar minimum had considerable influence in shrinking the Earth’s outer atmosphere. Key quote:
[The scientist] says the research indicates that the Sun could be going through a period of relatively low activity, similar to periods in the early 19th and 20th centuries. This could mean that solar output may remain at a low level for the near future. “If it is indeed similar to certain patterns in the past, then we expect to have low solar cycles for the next 10 to 30 years.”
Kepler discovers possible Earth-sized planet
Kepler had found a solar system with two Saturn-sized planets, plus a possible third planet 1.5 times the diameter of the Earth, with a mass three to four times as big.
New sunspots end short blank period on Sun
After a short four day stretch with no sunspots — the first time in months — two new sunspots appeared today. It is very possible that this will be the last time the Sun will be blank for years as it continues to ramp up to its next solar maximum.
Analysis of Hayabusa material extended
The publication of the results of the material found within the Hayabusa capsule has been delayed until December. The researchers have found that the particles in the capsule are smaller than expected, and they need more time to study them properly.
New exoplanets
Exoplanet news! Scientists today announced the discovery of a host of planets, all orbiting a single star similar to the Sun. Though five are Neptune-sized, a sixth (not yet confirmed) might be the size of Earth. What makes this even more exciting is that the astronomers made the discovery using a ground-based telescope.
But wait, there’s more! Thursday NASA will hold a press conference about a new discovery by Kepler!
More on the new Jupiter impact
More information on the recently discovered fireball that impacted Jupiter on August 20, including images.
Another Jupiter fireball
For the third time in the last year, Jupiter has been hit by a large previously unknown object.
Modern science
Why bother with research when all we need to do is ask our politicians? Scientist Hillary Clinton studies the floods in Pakistan and the forest fires in Russia and declares them both proof that global warming is happening!
Mount St. Helens
Today we hiked almost ten miles around Mt. St. Helens, walking down to the shore of Spirit Lake (see below) as well as tromping about on the debris field just below the crater. I will have a long post on the experience tomorrow.
