responsibility project

you might not think something called the responsibility project would be led by an insurance company, but liberty mutual leads the way this time. i really like this short clip pointed out by contando estrelas.



let me know if you find other good videos demonstrating responsibility, however you think that might be defined!

sideways saturn

i guess it depends on which side you think is saturn's front to determine whether its sideways right now. i think in our minds we all visualize saturn's rings as a dominant feature of the sixth planet from the sun, and how can we not when our little space robots take pictures like this for us to enjoy!!


while spacecrafts can zoom around objects to get different views, we are stuck with the perspective provided to the surface of the earth. from our vantage point, saturn's rings dont always appear at such an angle that we can see their extended beauty. saturn slowly rotates with respect to the earth, so that the rings sit at different inclination angles. richard bosman nicely demonstrates our varying views of saturn in this series of images taken over the period of time from 2005 to new years day 2009.


right now, saturn's rings are horizontal to the earth, with the rings very very thin and narrow... a position i think of as "sideways!" if you have the chance, view our ringed neighbor thru a telescope, via a local astronomy society, your own telescope, or a friends. saturn will not be properly viewable from the earth in this orientation again until 2038!

late this evening, 13 january 2009, provides a lovely chance to view saturn, the big, bright moon, and the star, regulus, lined up along the ecliptic.


enjoy the views!

poster design

this poster advertised the rachmaninov piano concert in 2007 commemmorating the september 11 world trade center events.


the concert is long past now, but i thought the design of the poster was really great! (link)

for anyone who eats

if i'm completely honest, creating a tasty new dish can be more satisfying than finding an unfathomably distant galaxy.

my success rate for cooking yummy food drastically increases with the freshness of the ingredients used. i think its true that the only culinary knowledge one really needs when preparing fresh ingredients is... dont over cook them - they taste good on their own! overcooking tends to make vegetables bland, unappetizingly mushy, and less nutritious!

the last year i lived in austin, i had fresh and delicious fruits and vegetables delivered to my front door once a week (as i've mentioned before). i enjoyed cooking regularly for myself and friends in order to eat all the produce in prime condition. i often froze dishes for surprise meals during busy and/or financially challenging weeks down the road.

when i moved to nottingham, i immediately missed my greenling deliveries, but realized that finding farmers markets and seeking similar home-delivery-of-local-produce services were potentially just a few internet searches away!

searching for recipes online provides an easy way to get ideas for how to store, cook, and combine any surprise items i receive. i still have to go to the store once in a while for yogurt, garlic, ginger, (alcohol,) bananas and/or any special ingredients required for a particular dish, but the convenience, health benefits, and cheap price of home delivery are unbeatable.

these are my personal reasons and methods for gathering food the way i do, but i find that my practices are included within the so-called slow food movement. to learn more about the slow food movement, specifically within the austin, texas community, i recommend this 10 minute video...

essential viewing for austinites, useful for anyone who eats:

hypermuchfuss

everyone loves clever acronyms, right?

glen petitpas keeps up the entertainingly comprehensive DOOFAAS - Dumb Or Overly Forced Astronomical Acronyms Site! you might notice that my name isnt as simple as it seems; amanda actually stands for - Antarctic Muon And Neutrino Detector Array.

but is it possible for the acronym game to go too far?

sarah askew shared with us on twitter this morning, that one group may have... at least i think the win the acronym game! a paper was released today called "The HYPERMUCHFUSS Campaign -- an undiscovered high velocity population." thats right, a survey referred to as HYPERMUCHFUSS which stands for - HYPER velocity or Massive Unseen Companions of Hot Faint Underluminious Stars Survey!

wow.

body puzzle

this is a clever idea:


although i can imagine much naughtier designs and locations on the body for such art...

star wars matryoshka dolls

i present to you some of the coolest russian stacking dolls (matryoshka dolls) ever!



these cute little creatures were hand-painted by the clever matt brown! he did an impressive job painting the light-sabers to look straight on the curved surface of the dolls.

where is Arp 220?

while peculiar galaxies might not seem as symmetrically pleasing as their spiral counterparts, the events creating their odd structures are quite exciting! the galaxy, arp 220 (the 220th object in halton arp's atlas of peculiar galaxies), represents a well-studied, relatively nearby (250 million light-years away) galaxy, that doesnt appear typical at all!


the hubble space telescope image above shows the optical view of a mashed-up, non-symmetric mess! arp 220 appears as one object, but as you can infer from the wisps of faint starlight curling around the outskirts of the galaxy, something unusual is occurring!

arp 220 is also the brightest object in the local universe, as it shines extremely brightly at both x-ray and infrared wavelengths. here is an image of arp 220 in the infrared, where it radiates 90 percent of its energy, making it a classic example of an ultra-luminous infrared galaxy (ULIRG = "you-lerg"):


so what explains all these crazy characteristics of arp 220? this peculiar galaxy is the result of two separate spiral galaxies colliding together to become one! the wispy tidal tails seen in the optical image are the result of some stars and gas getting flung out of each galaxy during their initial close encounters. other chunks of gas and dust get concentrated into dense clumps during the entire merger process, seen shining brightly in the infrared image. these dense regions of gas, cool enough to form stars - lots of stars! the newly-formed stars shine very brightly, but enough dust surrounds the star-forming gas clouds that the dust absorbs huge amounts of the stellar light and heats up! the dust naturally wants to cool off and does so by releasing light energy in the infrared... thus, we see arp 220 shining very brightly in infrared observations!

at its current rate of star formation, arp 220 will shine brightly in the infrared for about the next 40 million years! this sounds like a long time to our human scales, but its not that long, astronomically speaking. after 40 million years, nearly all the gas in arp 220 will have condensed into shining stars and the resulting galaxy should eventually look like a regular elliptical galaxy.

although arp 220 lives pretty close to our milky way galaxy, it represents potential to study what may have happened to the earliest galaxies that formed in our universe, since early galaxies experienced interactions and mergers with surrounding galaxies quite often!

my fellow graduate students and i used to joke about arp 220 because it seemed to be a favorite galaxy of a particular professor of ours. every time any of us presented results on any aspect of galaxies evolving, this professor would ask "and how would arp 220 fit in with your scenario?" or "where does arp 220 lie in that plot?" he was so predictable with these questions, that we all learned to expect them and prepared ourselves, and each other, for his inevitable comments.

even though we joked about his insistence with this particular galaxy, he taught me a good lesson about the universe - when trying to understand how things occur very far away and long, long ago, its good to take examples of local, well-studied galaxies to see if they can be explained by your new theories. if arp 220, or the milky way, or andromeda, or the magellanic clouds cannot be explained to some degree by your theory, then some aspect of it is not sufficiently comprehensive in its current form.

ironically, i now find that i ask myself quite regularly - "where would arp 220 be in that plot?" and the thought experiment often proves to be useful!

intentions for the new year

slow down

pay attention

question everything

start now


“simplicity is the ultimate sophistication.”

- leonardo da vinci

oh night... diiviiiiine!

just in case anyone thinks i was exaggerating about my annual family christmas extravaganza... here are a few nice photos that my cousin, jeff, took of this year's event!


grandma with the "christmas carol lyrics"


hahahaha! love it. thats my dad, two uncles and an aunt standing up - all siblings, of course :)


miss you all - glad to see your enthusiastic faces (and energetic entertaining, diane!!)!

ganymede plays peek-a-boo with jupiter

this image of jupiter and its largest moon, ganymede, was taken by the wide field planetary camera 2 (WFPC2 = "wif-pic-two") on the hubble space telescope. three images, taken april 9, 2007 in red (673 nm), green (502 nm), and blue (410 nm) filters, were combined to produce this sharp color capture!


hubble took a series of 540 pictures over a two hour period as ganymede appeared to approach the giant gas planet and disappear behind it! you can watch these images together as a great video at the hubble site.

here's an interesting image showing the scale and orientation of the observation. the white line at the bottom represents 25,000 miles (40,000 km)! consider that earth's diameter at the equator is only about 8,000 miles (12,800 km)!

my man, paul simon.

paul simon has been a favorite song writer of mine for a long long time. i used to sing a lot of simon & garfunkel songs with my pops, so the beautifully flowing melodies coupled with the simple harmonies reach right to my depths.

its hard to limit my choices of favorite songs, but i found a few good live recordings on the internets.

homeward bound - 1967



around 1970, paul simon and art garfunkel broke off their duet and paul went thru a series of musical experiements. early on, he stuck to his brilliant song-writing roots. (the stache in this recording is great!)

american tune - 1975



slip slidin' away



in the 1980's, my man paul went to africa to work on the "we are the world" project. while there, he worked with the powerful vocal group, ladysmith black mambazo, among others, to produce his most well-known solo album - graceland. not only was this album great to listen to, but it introduced much of the western world to "world music," and also resulted in one of the best music videos ever produced (in my opinion).

i know what i know:



and finally, feelin' groovy! ok, so the song is properly titled the 59th street bridge song (feelin' groovy), but i dont think anyone actually uses the whole title of the song, nor should they!

idyllic italy - the amalfi coast

i took these images in several cities along the amalfi coast of italy. the landscape is absolutely breathtaking, while the atmosphere reveals a tourist-dependence in the region - even during the off-season when i visited in november.

clear water.


the town of amalfi.




the duomo (cathedral) of amalfi.


altrani.






scratch that - i want to change my house number!


absolutely no bugling!


along the walk from altrani to ravello, a town whose name is derived from its onetime "rebellious" attitude!




scenes from ravello.










the world is full of ex-doorways.










cool lights in salerno




mmm.... pizza.


i stayed at hostels while traveling, but there are wide variety of amalfi hotels to choose from.

new years night

the planets are putting on a show for our benefit this last night of 2008! for a few hours after sunset, look for the bright planet venus right next to the crescent moon.

ready for the new year!

1907 was the first time they celebrated the new year in new york with the drop of a large illuminated sphere made of iron and wood. the ball was adorned with one hundred 25-watt light bulbs, was 5 feet wide and weighed 700 pounds!




times square, 1942 (link)

hope everyone is ready to welcome in a new year! be safe and happy!

two thousand nine

the year 2009 begins in a few short days! two thousand nine is the international year of astronomy as initiated by the international astronomical union and UNESCO "to help the citizens of the world rediscover their place in the Universe through the day- and night-time sky, and thereby engage a personal sense of wonder and discovery."

i'm excited about the 365 days of astronomy project, where different people from anywhere in the world talk about their interest in, fascination of, or knowledge about a particular aspect of the universe! there will be a unique podcast available for everyone to listen to every day next year! and there are still many days available throughout the year for anyone to create podcasts, so i encourage anyone and everyone to participate!

i've agreed to create a couple podcasts throughout the year, but i wanted to ask you all a favor... i'm looking for inspiration for more topics to talk about and so i'd like to get your suggestions. what questions do you have about the universe? what would you like to hear someone talk about for 5-10 minutes? my research focuses on galaxy formation and evolution, but i would be willing and interested to talk about anything if an interesting question sparks an idea. the challenge for me, i think, is that i'm so used to using visual aids in the classroom or on this blog, that it will be exciting to create the proper effect via auditory senses only.

thanks for your help!

family christmas carols

what i miss most while traveling is my family. this holiday season, i won't be home for christmas. while i'm enjoying the discovery of many british christmas staples (i cant believe i'd never heard of christmas crackers!), i'm feeling a bit homesick for all my family traditions.

every year, my dad's side of my family gathers together on christmas day. i have about 35 cousins on that side, so you can imagine the epic size of the event! for as long as i can remember, we have sung christmas carols together at the gigantic gathering on christmas day. in preparation for the singing, an excited energy floats around the room while people refill their bourbon slushies and find their place around the room. one uncle always leads the songs, sometimes unintentionally beginning songs on notes that make certain later notes quite unattainable to average voices! many harmonies are attempted and some are proudly achieved - although some years are definitely better than others!


the infamous song that makes everyone perk up, prepare their ears, and roll their eyes is oh holy night! the several-part harmonies reveal themselves as the family's volume increases excitedly. the voices intensify toward the climax of the song, when my aunts and uncles stand up, comedically reach out their arms, and wail "oh niiiiight diviiii-iiiine!!!!!!" inevitably, there is always an encore of the last verse of this christmas song, because the final crescendo is just so satisfyingly hilarious! at the end of this battered carol, we all smile and clap, and laugh at ourselves once again.

after going thru 20 or 30 carols, the last song we sing is always jingle bells.... dashing through the snow, in a one horse open sleigh.... as soon as this song begins, *santa* appears at the top of the stairs!! while we finish the song, he patiently makes his way to the christmas tree, through the rushing crowd of adoring children and jovial adults. at the end of the song we all cheer for santa and he tells us about his year. he usually adds a bad joke about the reds or the bengals or some other local college sports team. he distributes all the presents, one by one, with the aid of a few lucky little helpers. then we cheer him off again as he returns up the stairs to his sleigh.

when i was young and there were fewer family members, i grew to recognize santa as my uncle, mitch. now, it has become a little game to try to recognize who santa is among all of my too-grown-up boy cousins!

here's one of my favorite old pictures of the events - me, my cabbage patch doll and my mom singing with my cousin, her cabbage patch, and her mom... and the rest of the family!!!


the caroling spectacle was fun as a young child, horribly embarrassing as a teenager, and delightfully wholesome as an adult, because it's so much an endearing part of my family's culture. i will immensely miss the family gathering this year, so maybe i'll sing some carols by myself! happy holidays!
