In the desert working on LSST

This may seem like old news to some of you now, but earlier this year I moved across the world, back to the USA to the sonoran desert of Tucson, Arizona to start the next phase of my career: Head of Education and Public Outreach (EPO) for the Large Synoptic Survey Telescope (LSST).  

If you haven't heard of this amazing new telescope being built in Chile right now, here's an intro video I'm proud to have produced:


To find out more about the EPO program itself, you can watch the video below or see slides from a recent talk I gave.



Ida Luna and I are surviving our first desert summer and monsoon season - it's beautiful and dramatic and I can't wait to see what happens next!

new home :)

astro anecdotes

there are all sorts of astronomy folklore stories passed down through generations of astronomers.

did you know that the 107'' telescope at McDonald observatory has bullet holes in the primary mirror?

Six bullet holes in the primary mirror of the 2.7m telescope at McDonald Observatory.

I used to observe with that telescope all the time during my PhD and it was always fun to walk down the solid tube to see the "damage" up close.   the six holes only block 1% of the light and were filed smooth and painted black to stop any reflected light from invading the observations!

there is a blog now dedicated to recording all these stories i keep hearing over a beer at the pub - and many more i havent yet heard in person!

you can read them all here: astro anecdotes.

Top 5 Under 40 in Australian Science

I'm very proud to announce that I'm a finalist for the Top 5 Under 40 in australian science! As part of the program, I'll attend a workshop this Thursday and Friday to get media production and science communication training, and then pitch an idea for a radio program to the panel of judges. eek! also, woohoo!

This initiative is supported by UNSW and ABC Radio National to mark 40 years of The Science Show. The winners - the ‘Top 5’ - will be announced on The Science Show on 7 March.  fingers crossed!

aaron swartz - the internet's own boy - open access

it was 2 years ago today that aaron swartz ended his life.

the friend who recommended watching this documentary about him - the internet's own boy - described it better than i can.
A story of a bright mind, a great innovator and someone who wanted to make the world a better place instead of making money. 
A story of how the law and the system crashed someone who could have had an even more amazing technical and social impact. 
It's a good film - watch it.

i completely agree.  in fact, i cried during this film for more reasons than two.




in the first paragraph of his Guerilla Open Access Manifesto, aaron wrote:
Information is power. But like all power, there are those who want to keep it for themselves. The world's entire scientific and cultural heritage, published over centuries in books and journals, is increasingly being digitized and locked up by a handful of private corporations. Want to read the papers featuring the most famous results of the sciences? You'll need to send enormous amounts to publishers like Reed Elsevier.
i experience this everyday in how much myself and my institutions have to pay to publish and read science results. the cost is stifling. it's a racket. there are some solutions in the works, like the Public Library of Science (PLOS).

but of course some people will try to make money off anything, and the negative side of open access over the last couple years has seen the rise of predatory publishers. i receive regular invitations to publish in these "journals" and to give talks at bogus conferences.  to spot predators, look out for: bad spellings, copycat titles with a hyphen added, and check the Directory of Open Access Journals (DOAJ).

i think the culture within the "hard sciences" has a leading role in dictating how and what eventual laws will be enacted, because it is a progressive community relative to others, despite what it might feel like to the open access proponents within the community.  repositories like github and bitbucket are good examples of where open-source software can be developed in a public, collaborative way.

we need to be raising deep questions about content ownership and information access, both personal and otherwise, all across the internet. the time is now.

Cory Doctorow said: "Aaron had an unbeatable combination of political insight, technical skill, and intelligence about people and issues. I think he could have revolutionized American (and worldwide) politics. His legacy may still yet do so."

let's hope so.

anyway, watch that documentary.   it's incredibly interesting (and heart-breaking) and relevant.

classic astronomy question

i did a live radio show tonight, welcoming callers to ask any space-related question they wanted. the first caller was an 8 year old girl who asked "are stars made of gas?" (yes.) then she said her brother was with her and wanted to ask a question and was that ok? (sure.) the brother grabbed the phone, took an audible breath, and TOTALLY snuck in "how big is uranus?" LIVE ON AIR! haha! props, kid!


what would your answer have been?

(Sci-fi) books recommended

i asked twitter for some book recommendations.  either my twitter followers read a lot of science fiction, or they think i should read a lot more!

thought i'd share the list here, in case anyone is looking for new books. the ones i've chosen to start with are The Martian by Andy Weir and The Eyre Affair by Jasper Fforde, which each received quite a few independent recommendations!

the new ann leckie book, if you like sci-fi
fun sci fi-ish books: redshirts, ready player one, & mr. Penumbra's 24 hour bookstore
Brandon Sanderson series
great nonfiction: the immortal life of henrietta lacks & anything by mary roach (packing for mars is great)
The Southern Reach Trilogy by Jeff Vandermeer (sci-fi)
The Martian by Andy Weir (tale of Mars survival).
Fantasy-ish, which I usually don't like. Mistborn trilogy is complete. New one starts with Way of Kings -- also good.
Lock In (John Scalzi),
Fifteen Lives of Harry August (Clare North),
Girl with all the Gifts (M. Carey)
Southern Reach
Octavia Butler is always awesome. Martian and California are pretty good newer sci fi too :)
@jasperfforde's marvellous Thursday Next series. Starts with The Eyre Affair. Scifi, humorous, crime drama.
Quicksilver by Neal Stephenson….
Command and Control by Eric Schlosser
for a long recuperation: the Horatio Hornblower series.
@robertjbennett 's City of Stairs
Everything by @JonathanLHoward : start w/Johannes Cabal the Necromancer.
anything by Daryl Gregory or @maxgladstone .
Best non-fic of my year: Tony Judt's Postwar. Also Bloodlands (tho a painful read).
the Long Earth trilogy.
Unbearable Lightness of Being
@cantrell's Containment

feel free to add your own in the comments and i'll update the list.

dear blog

dear blog,

i do think about you, sweet blog.   i think about things i'd like to write and post and share and comment on, and then i cant seem to find the time.   it's some combination of my new(ish) job, that has me doing outreachy type things for the AAO during my days, and rekindling a couple old hobbies, that has taken my attention away from you.

i'll try to do better.  i want to do better.   in fact, i want to move you to a different host and redesign your look a bit. i've talked about this before, but i promise i will dedicate time and take action to do this soon. maybe some kind soul will even help (actually, i would pay them for their skills and time).
 
i have some good photos and stories in the works to post to you soon, so please be patient.  until then, old friend, to tide you over here are a few photos from last week when i was working in new zealand, so that you dont forget me.

jupiter layer cake

i'm slightly experimental with my baking and cooking, but this jupiter structural layer cake requires some serious skills and experience.   the layers are not to scale, but wow wow wow - look at the icing and the round layers inside.   so impressive!!   

Jupiter Structural Layer Cake: outside (Credit: CakeCrumbs)

Jupiter Structural Layer Cake: inside (Credit: CakeCrumbs)

the main feature most people recognize on jupiter's surface is the giant red storm - a hurricane twice the size of the earth!

Jupiter Structural Layer Cake: outside (Credit: CakeCrumbs)

the oddity of jupiter is its interior.   the giant planet has no solid surface on which one could stand and watch the stars.  instead, about 90% of the planet's atoms are hydrogen.  in the outer regions, the hydrogen is a transparent gas, like on earth, but then conditions change as you go deeper inside.

the pressure starts to increase as you go farther down towards the center, and the increased pressure makes the gas more dense, until it becomes "liquid metallic hydrogen" - a state of hydrogen not produced naturally on earth.

there is probably a rocky core at the very center of jupiter, but actually, we really dont know.

we'll know more about the biggest planet in our solar system, jupiter, soon(ish), when the spacecraft called juno reaches its destination in 2+ years.  the SWRI mission webpage has a cool animation of how we think our solar system and jupiter formed.  stay tuned!

professional female lego figures!

i just learned about Cuusoo - a platform where people can propose new LEGO ideas!  if a proposal gets 10,000 votes, then lego will consider producing the product for the masses.

i just found a set of designs to introduce professional female figures.   yes! if you like them, go VOTE NOW!

here is an astronaut, an astronomer, and a laboratory scientist:



a falconer (kinda random, but very cool!), a geologist digging, and an engineer building a robot!


a zoologist, a judge, and a mail carrier (who looks like a superhero)!



if you like these, go HERE and vote using the green button at the top right.

pockets of the internets

i dont do this very often, but i've been building up a collection of cool links which dont necessarily warrant entire entries on their own.   so, check out these fun corners of the internet if you have some time to enjoy:

- if you want to know what it's really like to live in australia, check out 26 daily occurrences in australia.  all totally true.  

kangaroo chillin at a pristine beach
- for a fantastic digital representation of time, please visit here is time.  very well done site.

- i havent actually read any of these, but the NY Times recommends these science books.  i've wanted to read quiet by susan cain and the power of habit by charles duhigg for a while.   let me know what you think of any you have read.

- my birthday is on may 26th, in case you needed an idea.   i also really like hand-written notes and postcards!  (thanks, ST ;)

- we all could learn a lesson from this couple on how to let loose and have fun!  also, i chose the second song last weekend for a (too late) evening of karaoke with friends!

- if you've ever wondered why the sky is blue (spoiler: it's not because it reflects the ocean), listen to our titanium physicists podcast on this question and also, what skies on other planets might look like!

- i was wondering why so many people were finding this blog by searching for "space whale."   i think i finally found the answer, but i can't believe it.

magnetic magic

i have a phd in astrophysics and yet magnets mystify me and seem like wonderful, natural magic.   i love being able to *feel* their force and resistance on tangible scales without being able to see what's going on. 

my birthday isnt too far away.   if anyone wants to either send me a post card or some of this "super magnetic thinking putty," you would make me a very happy super scientist!!  ;)

nerd nite sydney - the cape!

last week i spoke at nerd nite sydney - an evening event at a pub where scientists and comedians entertain a wonderfully excitable audience!   i really enjoyed the evening and received some great questions after my talk on the eventual fate of the milky way galaxy (spoiler alert: it collides with andromeda).

the fun news - i wore my cape ;) 


at least i wore it at the beginning and the end of the talk - the thing actually traps a lot of heat - too much to wear for a whole talk!



 


super.

mom visits australia

my mom has been with me in australia for the last month!   she flew back to the US this week, after we shared many fun adventures!  here are some photo highlights of our time together:


we explored some of sydney's northern beaches on a very blustery day.

beached
on a day drive southward, we stopped at this lovely spot for a relaxed lunch.

calming sun
 we were not the only ones enjoying this misty beach.

beachgoers

we flew north to the great barrier reef and stayed over night on a boat to maximize our snorkling time.

enjoying the salty air
we survived swimming with reef sharks, barracudas, sea turtles, incredibly diverse coral, colorful fish and we watched a giant fish turn over a huge rock looking for food. i only got stung by one tiny jellyfish.   it itched like a bug bite for a few days, but no worries.

green island
i think i saw comet panstarrs this night, but it was tough to tell.  mom wasnt convinced.  we still had a lovely view of the harbour bridge and the sunset!

sydney city light

we drove through the blue mountains and hiked to wentworth falls.   this photo only gives a hint of the full extent of the falls!

some of wentworth falls
while in the blue mountains, we stopped off to see the three sisters, all in a row. 

three sisters
we visited some lovely wineries a few hours away from sydney. 

peter van gent winery and vinyard
one day we enjoyed a sunny coastal walk and stopped at three blue ducks (one of my favorite restaurants!) for lunch. 

SPLASH! view to bronte beach
and we ended her trip with a bang - an opera at the opera house.   i enjoyed it, but didnt know la boheme is a tragedy!   oops.

mom and i go to the opera
isnt she lovely?   i think we havent spent so much continuous time together since before i moved away from home, many many years ago.   loved our time together.  :)

visible asteroid 2012 DA14

on feb 15/16, a little chunk of rock (45 meters = 150 feet across), known as asteroid 2012 DA14, which has been orbiting around the sun for a long time on a not-quite-circular orbit, will pass close by the earth. 

Photo Credit: NASA

actually, asteroid 2012 DA14 will pass very close to the earth - only 17,200 miles (27,680 kilometers) away, which is closer than the moon's orbit and even closer than some high-orbiting communications satellites!

but do not worry, asteroid 2012 DA14 will not hit earth

Photo Credit: NASA via Calgary Herald

the asteroid will not be visible to the naked eye, but should be visible using binoculars to many people across the planet, if you know where and when to look.  check out satflare.com or http://www.heavens-above.com/ to see if it will be visible where you are.
