Personal Updates (August, 2015)

25 Aug

Holy carp! I haven’t written anything since February. LAME. In my defense, grad school is the worst. Seriously kids, don’t throw your life away on college (that’s what I’m going to tell my hypothetical children someday).

Mercifully, I only have ONE class left! And it’s an online class. And it’s not hard because I already took all the hard ones. Actually, I did that with my undergrad too – my last undergraduate class (I am not kidding here) was Intro to Computers, an 1100, freshman class, no one ever wanted to take that was basically ‘how to use Microsoft and make a Power Point’. I’m not sure how I pushed that to my very last semester, but I did.

As long as we’re confessing to things, I may as well throw in that I failed PE (a requirement at my school) 3 times. 4th time was the charm though.

This year I got to teach an undergraduate class, just to try it out and see if a PhD is worth it, and I have to be honest – it is not. Don’t get me wrong, I’d like to have a PhD, but getting one is a) ridiculously expensive, b) cost-prohibitive, and c) did I mention I don’t have the money? I’ve looked into scholarships, but there are not a lot of graduate scholarships out there, and I don’t really want to teach at a university. I’m not even sure it’s worth the time, let alone the money. Don’t get me wrong, I think education is important, but I think it’s going in a very different direction. MOOCs are getting more recognized, and huge amounts of research using citizen scientists are becoming more popular too. I think the day when you can teach and conduct real research outside of a university is just around the corner. So maybe universities should drop their prices is all I’m saying.

So in conclusion, my personal update is this: I’m almost done with grad school, I’m in a very ‘we don’t need no education’ mood, and I have no idea what I’m doing.

I’m pretty sure that’s how everyone feels after college. Right?






p.s. Oh yeah – the good news! I got made president of a small astronomy outreach NPO. That made my whole year.

Nearby extrasolar planets are everywhere! Which is awesome sauce if you ask me.

How to Find Exoplanets (Transit Method)

17 May

How do astronomers find planets outside of the solar system? With the cunning use of spectroscopy.

Going Once…. Going Twice…

17 Apr

On Monday (ok, let’s be honest, it was really Tuesday) there was a full lunar eclipse.  I was at the observatory with hundreds of people (in a town so small you can drive from one end to the other in 10 minutes) for about 6 hours.  It was brutal.  Not because of the work, not because of the lateness, but because of the herds of people.

Oh sure, I may seem friendly on the surface, but after the first 56 people called it a ‘blood moon’ like the dead were going to rise from the grave, I started feeling a bit like Tim Minchin trying to explain how double-blind studies work to a girl named Storm.

It’s not that I have a problem with people – certainly not astronomy enthusiasts.  Generally, I have a problem with the media though, and in this case two things stuck out; calling it a “blood moon” as though that were special, and saying that it was a once in a lifetime event – both of which I later realized were problems of (mostly social) media.

So… the thing about lunar eclipses is that they are typically orange or red.  Also, they occur with great frequency, at least twice a year (although they are mostly partial so a full one is nice) and they are so, so, so not a once in a lifetime event.  Like even kind of.

Partial lunar eclipse 2011

Note the redness from this very partial lunar eclipse taken a few years ago.

Of course I was overjoyed to see so many people excited over the event.  Of course I was happy that lots of people came out. But there was a palpable deflation when people asked if this really was a once in a lifetime event, or if they’d ever get to see the ‘blood moon’ again like this and the answer was ‘of course’.  In fact, they could probably catch another one like this many times before they died.  Many people were clearly sad that this was in reality, not a once in a lifetime event.

That reality, that you will be able to see something only once is very strong in astronomy.  If you were alive in the 70’s-90’s, congratulations! Pluto got as close to us as it’s ever going to get in your lifetime.

Haley’s Comet, Comet Hale-Bopp, Comet Hyakutake, and Comet Pan-STARRS were all once in a lifetime events (unless you are Mark Twain).


You ain’t never going to see this again.

The Venus Transit was most definitely a once in a lifetime event (or twice in a lifetime if you were paying attention in 2004).

Venus Transit 2012

I almost cried that day. Not even kidding.

And there are plenty more where that came from.  If you were alive when Voyager 1 and 2 were launched, well, there was a planetary lineup that hadn’t happened since Jefferson was in office.

Sedna (my favorite planetary body EVER) will be at its perihelion (closest point) in 2076.  I’ll probably live that long!

Proxima Centauri is the closest star to us right now, but it hasn’t always been, and it won’t always be.  In 10,000 years, Barnard’s Star may be closer to us than Proxima Centauri, and in 30,000 some-odd years, Ross 248 will be closer to us than Proxima is now.

Movement of Close Stars

See that?  You are living the dream even as we speak.

And this is just astronomical phenomena.  We haven’t even talked about discoveries and human firsts.  There are so many astronomical discoveries that have occurred within your lifetime (even if you were born 12 months ago), I could make nothing but episodes on those, and I would never be finished.

Here are just a few that you have likely experienced:

  • Discovery of hundreds of new planetary moons in the solar system (over 20 were discovered in the year 2000 alone)
  • Discovery of extrasolar planets (1992)
  • Discovery of the first moon around an asteroid (1994)
  • Confirmation of the first brown dwarf (1995)
  • The discovery of multiple Plutoids; dwarf planets beyond Neptune (2004)
  • The Milky Way is shown to have a super massive black hole (2008)
  • The first probe enters interstellar space (2012)
  • First detection of an extrasolar asteroid (2013)

My point is, firsts and once-in-a-lifetime events are nice, but they’re not the most important part of astronomy.  They add to the pile of cool stuff, but they are not the pile itself.

No matter how common or how rare, it’s the experience, that counts.





How To Find An Extrasolar Planet (Using Radial Velocity)

Finding extrasolar planets is hard.  But humans are pretty dang clever.

You’re no match for us, space.

Just give up.

Humans Conquer Space Mysteries and Other Alarming Events (No. 1)

3 Apr 2012 VP 113

Last week (4th week of March, 2014) on planet Earth…

The humans continue to push out into space.  At this rate they’ll be capable of interstellar travel by the year 2233.  Of course, we are all alarmed, and measures to inhibit this activity are currently being discussed.

The humans’ need to catalog every little thing grows at an alarming rate.  Last week they discovered yet another dwarf planet in their outer solar system.  They are calling it: 2012 VP113, although we’re not entirely sure why (they have weird names for things).  This new object is not unlike the already discovered and similarly far from Earth body, Sedna.

planetary body 2012 VP113

This new body has the farthest perihelion of any planetary body the humans have yet discovered.

They figured out that it’s a small body, 300-1000 kilometers in diameter, and that it is moderately red.  This tells us two important things: They are finding new and interesting ways to “see” things they cannot naturally see with their eyes, and they are not able to detect us yet.  So nobody panic.

Galaxies for Beginners

This is a very brief introduction to galaxies.  It is more of a primer video, so if you don’t know anything about galaxies – you’ve come to the right place! 😀
