A Night to Remember

8:02 pm

An evening pause: With the death of film director Roy Ward Baker yesterday, I think it appropriate to watch a clip from one of his classics, A Night to Remember (1958). This understated but frighteningly powerful film captured the reality of the Titanic’s sinking in a style that is unfortunately rare today.

Asteroids of note

3:58 pm

At today’s press conference at the 42nd meeting of the AAS Division for Planetary Sciences, the topic was asteroids, including one which holds the possibility of hitting the Earth.

  • 65 Cybele has been found to have water ice and organic molecules on its surface, the second such asteroid so found. Key quote from the abstract:

    We conclude that 65 Cybele is covered by fine anhydrous silicate grains, with a small amount of water-ice and complex organic solids. This is similar to comets where non-equilibrium phases coexist, e.g. water-ice and anhydrous silicates; thus we conclude that this is a very primitive object.

    According to Humberto Campins of the University of Central Florida, this combination of water and organics could become hospitable to life should some form of energy be added, such as an impact to the asteroid.

  • The origin of the asteroid Phaethon, cause of the Geminids meteor shower, has been traced to the Pallas family of asteroids, a family created by the debris thrown out during a crater impact on the large asteroid Pallas. Campins also noted that this proves Phaethon is an asteroid and not a comet, a question that astronomers had been debating beforehand. Read the abstract here.
  • Asteroid 1999 RQ36, which has a 1 in a 1000 chance hitting the Earth in 2182 and is also the prime target of a proposed NASA sample return mission, has now been determined to be a member of the Polana family of asteroids. This makes 1999 RQ36 a very primitive asteroid from the very beginnings of the solar system. Moreover, this suggests that the Polana family could be the “most important” source of many near Earth asteroids. The abstract can be found here.

A Tea Party in Maryland

9:47 am

Last night I attended the most recent meeting of the Maryland Society of Patriots, a tea party group that was founded back in 2009. Attendance was pretty typical, with about fifty people filling the meeting room of the local library in Burtonsville, Maryland. As usual, Sam Hale, the founder of the group, had garnered a range of candidates to speak to us, including Eric Wargotz, the Republican candidate for the Senator, running against Barbara Mikulski (D-Maryland).

Eric Wargotz speaking at MSOP meeting

For Wargotz, the questions got a bit heated at one point, as one member of the audience wanted to know his commitment to defending the Constitution.

What makes this group significant is that the majority of its members come from very Democratic districts. Yet, not only has attendance been high at almost every meeting, the membership has including a wide range of ordinary people, most of whom have never done politicial activitism in their lives.

The basic ingredients of life might exist in Titan’s atmosphere

3:40 pm

Big news! In a simulation of the upper atmosphere of Titan at about 600 miles altitude, scientists have discovered the basic ingredients of life are quickly synthesized when exposed to the kind of hard radiation found there. Key quote from the press release, issued today at the 42nd meeting of the AAS Division for Planetary Sciences:

The molecules discovered include the five nucleotide bases used by life on Earth (cytosine, adenine, thymine, guanine and uracil) and the two smallest amino acids, glycine and alanine.

For those who don’t remember their high school biology, these nucleotides are the building blocks of DNA.

The abstract of the scientist’s work can be found here.

What the scientists did was recreate the basic ingredients of Titan’s upper atmosphere, comprised of nitrogen, methane and carbon monoxide. Cassini data has shown that within this atmosphere are very large molecules, as yet unidentified.

The scientists then bathed their recreation in the kind of intense radiation expected at that altitude, and amazingly produced the complex organic molecules that are basic to life. Moreover, the experiment was the first to produce these complex molecules without the presence of water, something that scientists have previously thought was required. These results suggest that in addition to forming in the oceans, life could also form in the upper atmospheres of planets.

This result also suggests strongly that it is incredibly easy to produce the basic building blocks of life, almost anywhere in the universe where organic molecules are present.

White House arbitrarily gives healthcare law waivers to some companies

2:47 pm

The law for some but not for others: Threatened with a firestorm of protest just prior to the election because a number of large corporations were going to drop millions from healthcare coverage because of the new Obamacare regulations, the White House today arbitrarily waived for one year those provisions for 30 large companies.

This action raises three obvious points:

  • If the healthcare law was so wonderful, why is the White House suspending its inception?
  • Why should these companies get a break, and not others? In fact, if I was the owner of a company that did not get a waiver, I would sue.
  • This once again proves false the claim by Obama that the law would force no one to lose their healthcare plan. To me, the words “You lie!” come quickly to mind.

Ed Morrissey at hotair.com makes some additional good points about this absurd situation.

Pluto’s ice: 97% nitrogen, 3% methane

4:00 pm

More results from the press conference going on right now at the 42nd meeting of the AAS Division for Planetary Sciences:

Pluto’s surface ice is made up of 97% nitrogen, 3% methane, while the surface of the Kuiper Belt object Eris (which is larger than Pluto) is even more rich in methane, with a make up of 90% nitrogen and 10% methane. Both measurements go down to a depth of about 10 inches. To see the abstract for this result, go here.

The atmosphere of Venus is 60% less dense at its poles

3:01 pm

By diving into the upper atmosphere of Venus above its north pole, Venus Express has found that the atmosphere there is 60% less dense than predicted. This from a press conference going on right now at the 42nd meeting of the AAS Division for Planetary Sciences. They plan an additional dive campaign during the next month. And they plan more dives, going deeper each time, as they judge the consequences to the spacecraft each time.

To read the abstracts of the Venus Express papers, go here.

Updated: The full press release, with images, can be seen here.
