What we’re doing this morning

Orbiting the sun!
Orbiting the sun!
Orbiting the sun!

At least that’s the word from my younger counterpart, who chanted this while marching around the dining room table.

We might go to the library too.

Across the Universe Day

Today at 7 p.m. EST, NASA is beaming the Beatles song “Across the Universe” toward Polaris, the North Star. Apparently, the moment is the exact time the song was recorded 40 years ago, and meant to be a “cheerier” greeting to aliens than the usual Morse code we routinely transmit into space. This event is also apparently part of NASA’s 50th anniversary celebration.

According to the Bad Astronomer, Polaris is far from the best star choice if the objective is to greet distant life forms, but it is one of the few stars that large numbers of humans know by name (outside of the sun).

Organizers are encouraging people to listen to the song at the same moment all around the world. There is more information about it here. The event will also be broadcast on NASA TV online.

For today, we’ve put the song at the top of our Cosmic playlist:


P.S. Declan doesn’t believe me that this is a Martian crater because it isn’t red.

A nice day on Mars

For those of you who aren’t keeping up on space news, some neat stuff happened this week.

First, NASA’s space probe Messenger shot back images of planet Mercury that revealed a mysterious crater that scientists are calling “the spider.” I don’t know all of the details, but apparently Mercury and our moon aren’t as similar as once was thought. (I never realized how similar they were until my house became overrun with myriad cardboard and plastic planets – we’re always getting Mercury and the moon mixed up around here.)

And, pictured here is an image posted by The Planetary Society blog of a smiley-face crater on Mars. It was taken by a camera that’s cataloging the surface of the red planet in super high resolution from the Mars Reconnaissance Orbiter.

Declan was already asleep when I found this post tonight. I can’t wait to show it to him in the morning. It looks like one of his drawings.

A really big dream

I went to bed chilled with a fever last night. I took a little Tylenol, drank a lot of juice (I don’t do cold medicine) and crawled under a heap of blankets.

Then I dreamed that I became a cosmic string. I extended from the earth. I saw Heath Ledger on the way. I heard Eric Idle singing The Galaxy Song. I grew longer than the solar system, the Milky Way, past Andromeda and other galaxies. I became the length of the entire universe.

And as all of this was happening, I was thoroughly convinced that I was getting very important information that I had to bring back to share with Earth’s astrophysicists. The things I saw were going to change the world. I can’t remember the last time I had a dream that vivid, or was so thoroughly hoodwinked that everything about it was real.

I certainly never dreamed on this scale before. Thank you again, my son, for making me aware of how much of the universe I had been missing.

House key

In this case, I mean this definition of “key”:

A systematic explanation of abbreviations, symbols, etc., used in a dictionary, map, etc.

Having a toddler means that you likely have a few words or phrases that have meaning around your own home, but would completely confound strangers. Here are a few of ours:

Pop bottles = Children who are acting silly

Monkeypuppy = Meerkat

String theory music = classical music

Planets noodles = Israeli couscous

Have any of your own house language to share, either from your kids or from your own childhood?

Mars and the moon hold court

A year ago, if you’d asked me to look up in the sky and tell you which of the distant dots were planets and which ones were stars, I wouldn’t have been able to do it. I’ve had a few wee hour adventures into the farmlands to watch a meteor shower, stared at a comet through a telescope and traced Orion’s Belt and the Big Dipper in the sky with my finger, but that’s the extent of my astronomical prowess.

So much of our world revolves around space now. The other morning, after we watched Declan slip planets from a cardboard solar system in and out of their box Dan asked me, “have we had a day in the last year where we didn’t hear the word Jupiter before noon?” I had to say no.

Our love of Jupiter runs deep. But we have affection for all of the planets, whether they are in books, on mobiles or on television documentaries. At a summer festival last year, friends looked on as Declan cried when Venus vanished behind a cloud.

Tonight, we were out running errands after sunset, and looked up at the waxing Gibbous moon in the darkening blue sky from the Sears parking lot in the bitter cold air. There weren’t any stars visible, but there was one planet, shining brightly right next to the moon. It was so vivid, I guessed it was Venus, but I came home and checked the Sky Calendar, which told me it was Mars. The three of us stood in there, pointing and oohing and making our guesses until we couldn’t stand the cold any longer. (According to that link, there is a “wind child” advisory here.)

If you are fortunate enough to be in warmer climes with clear skies tonight, or have a great North-facing window, be sure to tell Mars hello for us.

This is a galaxy

That’s what Declan told me this week.

It is a disk, like our Milky Way.

He’s been collecting them.

“Can I have another galaxy, mom?”

“Can you find me another galaxy?”

We have a galaxy bank.

We are far richer than we imagined.

Earth boy

Wisdom, while enjoying a “blueberry Mars” popsicle last evening:

“Earth is a good boy.”

He considers this for a minute, then corrects himself.

“No, Earth is not a boy. Earth is a good ball.”

At bedtime, he turned to Dan and said:

“It’s a nice sunny day downstairs.”

The specter of cousin Eugene, part two

Continued from this post.
I’ve subscribed to a variety of developmental newsletters ever since the week I found out I was going to be a mother. During my pregnancy, I enjoyed seeing what food item they would compare my baby’s size with each week (shrimp, lime, coconut) and which parts of his body were forming.

For the first year of Declan’s life, the weekly email missives let me know the scope of abilities that he could have, and told me which ones he definitely should have. They reassured me that I had some idea what I was doing as I got the inevitable questions from the many many expert strangers that a baby’s presence in the world invites. They reinforced certain notions I had been given about parenting that might make you look crazy, particularly to the non-parenting world, like my sister-in-law’s suggestion that I talk to Declan about the daily things we did to help his language skills develop. It’s somehow easier to justify the loony look of talking to your six-month-old about a Diane Arbus photograph at MOMA or the uses for red cabbage at the grocery store when you know that what you can point to the effectiveness of your actions underneath an “expert” heading somewhere.

These days, the newsletters appear monthly. The last one came on Declan’s two and half year birthday. It suggested that at his age, he should know a few colors, body parts and people, and be speaking in two-word sentences.


“You can help her improve her verbal skills by giving her details,” writes the cheerful email. “If she says, ‘Dog sleep,’ for example, you might say, ‘Yes, Spot is curled up and fast asleep on the chair.’ She can’t imitate your complex language patterns just yet, but she’s learning more all the time.”


This visited my inbox during a week when Declan has repeatedly been reciting the following (his shorthand of a part of the narrative from the documentary 95 Worlds and Counting):


You go down into the holes, if you dare, re-verberating, supersonic gas rushing out.
A pool of liquid nitrogen boiling fervently.
When nitrogen boils, intense pressure builds, until the geyser finally ends.


While visiting my brother’s farm over Thanksgiving, I tried to settle him down after a full day of cousin playtime. The usual lullabies, like “Hush Little Baby” (known to us as “Baby in Town”), weren’t very effective.


“Can you sing about liquid nitrogen?” He asked me sweetly.


I tried. I really did.


And that, like dozens of other stories about the things that occur in our daily life, can be related with innocent intentions and still end up making me feel like Cousin Eugene’s mom.
The divide between celebrating his appetite for learning and being perceived as a braggart is a hairline. Some look at me as though I must be one of those Olympic coach parents who insists on putting him through wicked daily mental gymnastics, rather than a person who simply tries to open the channels to the things he shows interest in. Fortunately, others, sometimes strangers, take in his qualities and marvel at him with me.

Declan’s
own actions in public can have a similar effect – sometimes his interests can completely throw people who don’t expect that his answers to ordinary questions will be quite so complicated. And while some people react beautifully, others look at him like a mutant (particularly seven-year-old boys).


I do see every child as brilliant in their own right – in ways that manifest differently, and certainly with widely varying degrees, including some that aren’t so obvious. Yet culturally, we are so prone to compare individuals, to see confidence and the celebration of accomplishment as things that make us somehow personally deficient, not healthy and happy and learning. I try to see these things in Declan’s peers and appreciate the things that they can offer each other.


Parenting magazines constantly tell us that all kids learn at their own rate, and remind us that we shouldn’t read too much into a child’s abilities at a young age. After all, Albert Einstein had early speech delays. Neurosurgeon Dr. Harvey Cushing had dyslexia, as do novelist John Irving, artist Robert Rauschenberg and billionaire Richard Branson. The same publications, along with other, more experienced moms also remind me regularly that Declan’s esoteric interests in space may just evaporate one day, and that it would be completely normal for him to forget many of the things that he knows so well right now.


I try and keep my own opinion – and expectations – of him in check, for both of our sakes. But when he gets as excited about science and scientists as he would if Steve from Blue’s Clues walked into the house for dinner tonight, it’s hard not to bask in the glow all that he is becoming and feel proud.
