CHALKING THIS UP TO SPECULATIVE SCIENCE. BUT SPECULATION IS FUN. AND SO IS SCIENCE. SO LET’S DOOO THISSS.
Guys. Guys. Guys! Seriously. It’s serious this time. For now. It’s like, legit. Voyager 1 is the first human-made spacecraft to leave our solar system. Those other times we thought it it? Forget them. This is legit. Stop grimacing with skepticism. This is the truth.
[Update: It hasn’t. I frigging knew it.]
Voyager 1 has totally left the solar system. This time it is for real. Right? I feel as though I have written nineteen different posts about Voyager 1, and whether or not it has crossed the cosmic Rubicon Now comes a paper that has confirmed the spectacular leap for mankind. We get to keep it this time, right? Please?
Fare the well, Voyager 1. You’re currently hauling ass through the “magnetic highway”, as you approach the limits of our solar system. Keep in mind our wonderful moments together. Recall, if you will, the time we built your ungrateful ass. Fawn over the concept of being the first object we’ve sent out of our solar system. Dearest regards.
Our fat brains can’t really process things. Consider Saturn’s sheer enormity in comparison to us. Then try and comprehend how small in relation to the sun. Then appreciate how fucking small the Sun is in the grand scheme. Nosebleed incoming!
You can cancel those high-fives, folks. Despite reports last year that Voyager 1 was finally throwing up the deuces to our solar system, new intel suggests we may be looking at a much longer exit timeline. Hope your liver and heart is well, ’cause if you want to be alive for this grand event you may need another decade and a half.
Now, those sand dunes on Mars aren’t actually flowing like liquid. You’re looking at me incredulously. They aren’t. Believe me. However, I’m not going to fault you for thinking they are.
Have you seen an aurora? I sure haven’t. My experience with them have been confined to Skyrim. Don’t get me wrong, those were gorgeous, I would just much prefer seeing one in person. Now, what could be more fantastic than that? Seeing one on a foreign planet.
A smidge old, but I kept forgetting to post it. This is for you!, person who hasn’t seen this yet. NASA has released a video detailing the entire evolution of the Moon in almost three minutes. It’s goddamn fantastic.
Well then! The solar system turns out to be no better than my Mom, for it has been lying about it’s fuggin’ age for some time now. It’s okay solar system, I still think you’re gorgeous, and resplendent, et cetera. In fact, you have a nice, mature glow to you. Nothin’ to be ashamed about.
Without celebrating a birthday, the solar system just got hundreds of thousands of years older.
To deduce when its first solid grains formed, researchers analyse structures up to a centimetre across found in meteorites. Such “inclusions” were created when gases cooled to form the sun and planets and are among the oldest solids in the solar system.
Now Audrey Bouvier at Arizona State University in Tempe, and colleagues, have analysed inclusions in a meteorite that fell to Earth in north-west Africa in 2004.
Based on the extent to which uranium-238 and uranium-235 isotopes had decayed into their daughter isotopes lead-207 and lead-206, they say the solar system is 4.5682 billion years old. That’s between 0.3 and 1.9 million years older than previous estimates, which relied on the Efremovka and Allende meteorites found in Kazakhstan in 1962 and Mexico in 1969, respectively.
Seriously, you can barely see the entropy, solar system. I won’t tell no one the truth, anyways.
