A little while back I posted a dramatic satellite image of the Soufrière Hills volcano on Montserrat erupting (thumbnail on the right; click to get the embiggened shot).
Well, as from above, so it is from the side as well. Canadian tourist Mary Jo Penkala was on a plane near Montserrat at the time, and after the pilot made an announcement for passengers to look out the port window, she snapped this:
Wow! I’ve seen a lot of amazing things out my airplane window, but never anything close to this. Ms. Penkala is enjoying a bit of well-deserved notoriety for the picture. It’s amazing in and of itself, but I love how we now can get so many views of volcanic plumes: from below, the side, and even from space. These natural disasters cause a huge amount of damage and grief, of course, but the good news is that with enough study we can learn more about them, how to predict them, and when is the best time to get people out of any potentially dangerous regions.

Throughout his 30 years at NASA, Stofan held numerous managerial and administrative positions. His technical expertise was bolstered by a healthy dose of "charisma and confidence" that gained him the admiration of the rank and file within the agency and contracting organizations.
Stofan began his career as a research engineer at Lewis Research Center in 1958 and later joined the Propellant Systems Section of the original Centaur Project Office, where he began a steady climb through the tiers of management to become Director of Launch Vehicles in 1974. Much of the Titan-Centaur vehicle's success can be attributed to Stofan's leadership of NASA, the Air Force and aerospace industry teams. By 1978, Stofan was called to Headquarters to serve first as the Deputy Associate Administrator for the Office of Space Science, and then as Associate Administrator.
Stofan returned to Cleveland in 1982 as Lewis' fifth Center Director charged with the task of implementing Lewis' first strategic plan. The center had never had major roles in Manned Space Flight projects, but Stofan saw these big programs as an opportunity to make Lewis more visible within NASA. Stofan aimed for five major projects for the Center: the power system for the space station, the Advanced Turboprop Program, renovations of the Altitude Wind Tunnel (AWT) for expanded icing research, the Advanced Communications Technology Satellite Program and the Shuttle/Centaur Program. Amazingly, he secured funding for all but the AWT renovations. Most of the programs in the first strategic plan are still thriving.
In addition to implementing the center's strategic plan, Stofan instituted a new management style. He advocated participative management over the autocratic management style of the 1970s. His outstanding work managing advanced research and technology programs for NASA earned him the 1985 Presidential Rank Award for Distinguished Executives.
Following the Challenger tragedy in January 1986, NASA asked Stofan to return to Headquarters as the Associate Administrator for the Space Station Office where he led the negotiations of the international technical agreements and the U.S. contract to build the space station until his retirement on April 1, 1988. He continued to work in the aerospace industry for the next 10 years.
Stofan and his wife, Barbara have settled into a new lifestyle and home 7200 feet up into the mountains of Steamboat Springs, Colo., where he can daily enjoy one of his favorite past times—downhill skiing. He also enjoys golfing and building furniture. The couple travel extensively, including a recent trip to Maui to celebrate their 75th birthdays; to Ohio three times a year to Hiram College for Board Meetings where he has served as a trustee for the past 25 years; and to Virginia and New York to visit their daughters and five grandchildren. His daughter, Dr. Ellen Stofan, is a planetary geologist known for her work on Venus and Titan. His other daughter, Lynn, is an attorney.

"This is an exploratory project. Nobody has done this before at a wavelength sensitive to the heat from dust circling around so many stars," said John Stauffer, the principal investigator of the research at NASA's Spitzer Science Center, located at the California Institute of Technology in Pasadena. "We are seeing a lot of variation, which may be a result of clumps or warped structures in the planet-forming disks."
The new image was taken after Spitzer ran out of its coolant in May 2009, beginning its extended "warm" mission. The coolant was needed to chill the instruments, but the two shortest-wavelength infrared channels still work normally at the new, warmer temperature of 30 Kelvin (minus 406 Fahrenheit). In this new phase of the mission, Spitzer is able to spend more time on projects that cover a lot of sky and require longer observation times.
One such project is the "Young Stellar Object Variability" program, in which Spitzer looks repeatedly at the same patch of the Orion nebula, monitoring the same set of about 1,500 variable stars over time. It has already taken about 80 pictures of the region over 40 days. A second set of observations will be made in fall 2010. The region's twinkling stars are about one million years old - this might invoke thoughts of wrinkle cream to a movie star, but in the cosmos, it is quite young. Our middle-aged sun is 4.6 billion years old.
Young stars are fickle, with brightness levels that change more than those of adult, sun-like stars. They also spin around faster. One reason for the ups and downs in brightness is the existence of cold spots on their surfaces. Cold spots are the opposite of "age spots" - the younger the star, the more it has. The cold spots come and go as a star whips around, changing the amount of light that reaches our telescopes.
Stellar brightness can also change due to hot spots, which are caused by gas accreting onto a young star from the material out of which it formed.
"In the 1950s and 60s, astronomers knew that younger stars varied, and they postulated this had something to do with the birthing process," said Stauffer. "Later, with improved technology, we could see a lot more and learned a great deal about the stars' spots."
Spitzer is particularly suited to study yet another reason why the stars are changing. The telescope's infrared sight can see the warm, dusty disks orbiting around them. These disks are where planets may eventually clump together and form. When the disks are young, they can have asymmetries, possibly caused by forming planets or gravitational disturbances from formed planets. As the skewed disks circle around a star, they block varying amounts of starlight.
By gathering more and more data on these varying disks, Stauffer and his team hope to learn more about how planets develop -- not exactly tabloid fodder, but an ongoing drama of one large, stellar family.
NASA's Jet Propulsion Laboratory in Pasadena, Calif., manages the Spitzer Space Telescope mission for NASA's Science Mission Directorate, Washington. Science operations are conducted at the Spitzer Science Center at the California Institute of Technology in Pasadena. Caltech manages JPL for NASA.

Quotes because you might not find it counterintuitive, Self-Esteem Development From Young Adulthood to Old Age: A Cohort-Sequential Longitudinal Study:
The authors examined the development of self-esteem from young adulthood to old age. Data came from the Americans’ Changing Lives study, which includes 4 assessments across a 16-year period of a nationally representative sample of 3,617 individuals aged 25 years to 104 years. Latent growth curve analyses indicated that self-esteem follows a quadratic trajectory across the adult life span, increasing during young and middle adulthood, reaching a peak at about age 60 years, and then declining in old age. No cohort differences in the self-esteem trajectory were found. Women had lower self-esteem than did men in young adulthood, but their trajectories converged in old age. Whites and Blacks had similar trajectories in young and middle adulthood, but the self-esteem of Blacks declined more sharply in old age than did the self-esteem of Whites. More educated individuals had higher self-esteem than did less educated individuals, but their trajectories were similar. Moreover, the results suggested that changes in socioeconomic status and physical health account for the decline in self-esteem that occurs in old age
As a person well under 60 but slowing walking in that direction I’m pretty heartened by this. On the other hand, I’m one o those people who also tend to think that “self-esteem” is a bit overrated, so I’m not that heartened.

At the tip of Mexico’s Baja Peninsula a narrow breach in the sheer rock walls shelter two delightful beaches, Lover’s Beach and Divorce Beach. Lying back-to-back on this narrow isthmus, Lover’s Beach faces the Sea of Cortez and Divorce Beach faces the Pacific Ocean. The only way to visit these two gems is by boat, but fortunately this is no problem, since dozens of glass-bottom boat captains at Darsena Marina are only too happy to whisk you across the harbor for a fee of $5-6 per person.
Lover's Beach, tucked around the corner from the famous rock arch
While it is simple to arrange for passage, it is more difficult to actually set foot on these beaches. The waves here are often high and strong, and there is no dock. Captains bring their launches as close to shore as possible at Lover’s Beach, but passengers must ultimately jump out into the water, so it is advisable to wear swimwear and not bring a lot of gear. When the waves are not rough, it is possible to swim and even snorkel a bit at Lover’s Beach, as long as you do not round the point. Currents on the Pacific side are so strong that it is not advisable to get into the water at all; the rough seas here are perhaps the reason it was named Divorce Beach.
Lover's Beach on the Sea of Cortez side at Land's End
Once on the beach, the scenery is astounding: soft creamy pink sand with aquamarine water, all surrounded by towering rock spires painted black, ochre, and brown. Shake out your beach towel and enjoy a cerveza (beer) from one of the vendors who haul drinks to the beaches in coolers every morning. Or search the rock nooks and crannies for pirate graffiti. In the 1940’s, John Steinbeck wrote about Lover’s Beach, which was then called Playa Doña Chepa:
“The tip of the Cape at San Lucas, with the huge gray Friars standing up on the end, has behind the rocks a little beach which is a small boy’s dream of pirates . . . and this little beach must so have appealed to earlier men, for the names of pirates are still in the rock, and the pirate ships did dart out of here and did come back.“
After a few hours (or at whatever time you have pre-arranged) your captain will return to pick you up. Unless the seas are extremely calm on the day you visit, getting back into the boat can be a challenge, necessitating wading out into the water and timing your jump with the trough of a wave. But despite the challenges, a visit to Lover’s and Divorce Beaches is definitely worth the trouble.
