In this case, the carbon and oxygen are coming from a much more mundane source: the solar wind.
When high-energy particles from the solar wind collide with molecules in Venus’ upper atmosphere, they carry enough energy to break some of those molecules into their constituent atoms. Since the Venusian atmosphere is almost entirely CO2, you should expect this process to generate C and O ions — which is exactly what we’ve now observed!
If life is proven to exist on Venus, it would be really exciting. Besides the obvious reason to be excited there’s also my thought: If in this planetary system two planets out of 98 have life on them, then that would mean that life isn’t as rare as we conceived it to be.
Edit: Had the tab open for a while without refreshing before posting, so I didn’t see the comment that says it’s just solar wind. :(
The new flexible polymer and carbon composite boom is coupled with a twelve-unit (12U) CubeSat built by NanoAvionics. After the mission launches atop a Rocket Lab Electron rocket from the company’s Launch Complex 1 in Māhia, New Zealand, the spacecraft will go into a Sun-synchronous orbit at an altitude of about 600 miles (~1,000 km) and the sail will deploy in about 25 minutes to cover an area of 860 ft² (80 m²) with the boom unfolding from the size of a hand to 23 ft (7 m) long. Once deployed, the sail will adjust the vehicle’s orbit by angling itself in relation to the solar wind.
I know that's not how the phrase is meant to be read, but I can't unsee it as it flying separately by the earth and the moon and deciding to buzz one of the two a bit closer.
This means it’s an asteroid with a weight-class that would have burned up in Earth’s atmosphere, if its orbit happened to intersect ours more directly.
A quick search suggests that something as small as 5 meters can survive hitting the ground, however there are a number of calculations to consider including the speed it is traveling, the entry angle, and the material it is made of.
I didn’t plan to view the eclipse over Potato World, but arriving at the hotel and discovering that it was next door did seem like a sign from the universe.
I’ve got a few years of waiting on you, but never made an eclipse a priority to see. This one was close enough where I had no excuses. And I had the day off with the kids. We drove many hours to get to Plattsburgh, NY in the hopes that the event wouldn’t be obscured by clouds, we had a choice between that and Ohio. Looks like Ohio did pretty well, we had a high cirrus cloud layer but it wasn’t enough to disrupt the view. I wouldn’t call myself an astronomy buff, but Space has always held huge interest in my life, so dragging the family out for this event was kinda a big ask because they weren’t necessarily into it. I hoped the trip would be worth it, both weather-wise and stellar phenomena-wise.
Worth it. There’s no words to describe the ethereal, silvery ring that magically appears during totality. Bailey’s beads and more. Sure, there are photos and videos, but that doesn’t do justice to the play of light in the environment surrounding the viewer, the night-yet-still-day incongruity.
Everyone is taking home some joy from the experience.
We tried to capture a photo of total, but due to a comedy of errors, it didn’t happen, so the memories will just have to stay in our heads.
I hope anyone near an eclipse’s path of totality won’t write it off if they have a choice. Go see it. Truly a sight.
This is the kind of thing where even if kids don’t seem to really be interested in it, even if they don’t seem impressed, it’s such an incredibly rare and unique event (close enough to home) that they will always remember it. Maybe not to the point of thinking about it every week, but in the sense that every mention of solar eclipses, at the very least, will remind them of this one moment in totality with you. You can plant some seeds for interests without knowing what will take root while still knowing the seed stays there.
