You Know, Sometimes All You Need Is Twenty Seconds Of Insane Courage. Just Literally Twenty Seconds Of

Cleaned up my shelf today 📂

I love people with obscure knowledge or useless academic insights. I want to hear your analysis of lighting in Ratatouille. Tell me about the history of soda pop or the references to classical mythology in Macbeth. I want to know about the underlying homoerotic context of that 1930s sci-fi paperback. I think all knowledge is worthwhile knowledge. Explain to me the ecosystems that komodo dragons inhabit. Don't be afraid to learn for the sake of learning.

I know i look cute, but i’d look even cuter with 5 new books in my hands, i’m just saying

Salut! Hallo! Hola! Ciao!

I need more European studyblrs on my dash! Reblog if you’re from Europe and I’ll follow you! 

Take a look at my studyblr too :D

Cassini Spacecraft: Top Discoveries

Our Cassini spacecraft has been exploring Saturn, its stunning rings and its strange and beautiful moons for more than a decade.

Having expended almost every bit of the rocket propellant it carried to Saturn, operators are deliberately plunging Cassini into the planet to ensure Saturn’s moons will remain pristine for future exploration – in particular, the ice-covered, ocean-bearing moon Enceladus, but also Titan, with its intriguing pre-biotic chemistry.

Let’s take a look back at some of Cassini’s top discoveries:  

Titan

Under its shroud of haze, Saturn’s planet-sized moon Titan hides dunes, mountains of water ice and rivers and seas of liquid methane. Of the hundreds of moons in our solar system, Titan is the only one with a dense atmosphere and large liquid reservoirs on its surface, making it in some ways more like a terrestrial planet.

Both Earth and Titan have nitrogen-dominated atmospheres – over 95% nitrogen in Titan’s case. However, unlike Earth, Titan has very little oxygen; the rest of the atmosphere is mostly methane and traced amounts of other gases, including ethane.

There are three large seas, all located close to the moon’s north pole, surrounded by numerous smaller lakes in the northern hemisphere. Just one large lake has been found in the southern hemisphere.

Enceladus

The moon Enceladus conceals a global ocean of salty liquid water beneath its icy surface. Some of that water even shoots out into space, creating an immense plume!

For decades, scientists didn’t know why Enceladus was the brightest world in the solar system, or how it related to Saturn’s E ring. Cassini found that both the fresh coating on its surface, and icy material in the E ring originate from vents connected to a global subsurface saltwater ocean that might host hydrothermal vents.

With its global ocean, unique chemistry and internal heat, Enceladus has become a promising lead in our search for worlds where life could exist.

Iapetus

Saturn’s two-toned moon Iapetus gets its odd coloring from reddish dust in its orbital path that is swept up and lands on the leading face of the moon.

The most unique, and perhaps most remarkable feature discovered on Iapetus in Cassini images is a topographic ridge that coincides almost exactly with the geographic equator. The physical origin of the ridge has yet to be explained…

It is not yet year whether the ridge is a mountain belt that has folded upward, or an extensional crack in the surface through which material from inside Iapetus erupted onto the surface and accumulated locally.

Saturn’s Rings

Saturn’s rings are made of countless particles of ice and dust, which Saturn’s moons push and tug, creating gaps and waves.

Scientists have never before studied the size, temperature, composition and distribution of Saturn’s rings from Saturn obit. Cassini has captured extraordinary ring-moon interactions, observed the lowest ring-temperature ever recorded at Saturn, discovered that the moon Enceladus is the source for Saturn’s E ring, and viewed the rings at equinox when sunlight strikes the rings edge-on, revealing never-before-seen ring features and details.

Cassini also studied features in Saturn’s rings called “spokes,” which can be longer than the diameter of Earth. Scientists think they’re made of thin icy particles that are lifted by an electrostatic charge and only last a few hours.  

Auroras

The powerful magnetic field that permeates Saturn is strange because it lines up with the planet’s poles. But just like Earth’s field, it all creates shimmering auroras.

Auroras on Saturn occur in a process similar to Earth’s northern and southern lights. Particles from the solar wind are channeled by Saturn’s magnetic field toward the planet’s poles, where they interact with electrically charged gas (plasma) in the upper atmosphere and emit light.  

Turbulent Atmosphere

Saturn’s turbulent atmosphere churns with immense storms and a striking, six-sided jet stream near its north pole.

Saturn’s north and south poles are also each beautifully (and violently) decorated by a colossal swirling storm. Cassini got an up-close look at the north polar storm and scientists found that the storm’s eye was about 50 times wider than an Earth hurricane’s eye.

Unlike the Earth hurricanes that are driven by warm ocean waters, Saturn’s polar vortexes aren’t actually hurricanes. They’re hurricane-like though, and even contain lightning. Cassini’s instruments have ‘heard’ lightning ever since entering Saturn orbit in 2004, in the form of radio waves. But it wasn’t until 2009 that Cassini’s cameras captured images of Saturnian lighting for the first time.

Cassini scientists assembled a short video of it, the first video of lightning discharging on a planet other than Earth.

Cassini’s adventure will end soon because it’s almost out of fuel. So to avoid possibly ever contaminating moons like Enceladus or Titan, on Sept. 15 it will intentionally dive into Saturn’s atmosphere.

The spacecraft is expected to lose radio contact with Earth within about one to two minutes after beginning its decent into Saturn’s upper atmosphere. But on the way down, before contact is lost, eight of Cassini’s 12 science instruments will be operating! More details on the spacecraft’s final decent can be found HERE.

lots of chemistry revision today after being super unproductive for my first week of winter break 🌟 (also sorry i’ve been quite mia for a few weeks, i’ve been SO busy and my queue ran out)

follow spree

hey! you guys are amazing so I decided to do a follow spree!

so, if you are a studyblr/similar kind of blog, like/reblog this post & maybe follow me and i will check you out!

🌻 life lately has been good!

🌻 i've been trying my hand at green smoothies. unfortunately, out blender isn't powerful enough, so there were still some tiny spinach pieces in my smoothie haha. still tasted yummy and felt healthy tho!

🌻 also, i've been trying to stick a bit more to a skincare / health routine, including probiotics for my ibs, lotion after showering, niacinamide in the morning, and retinol in the evening.

🌻 mischa and i recently went to ikea with his mom. our plans to move in tgt are slowly taking more shape, we're looking for apartments that will be free anytime after november, and are thinking about which furniture we need. ikea was super fun, we saw and noted some pieces we liked, and had köttbullar :) also, i got some cute cacti!!!

🌻 i'm still working hard on my ma thesis, but i'm trying not to stress out too much over it. next due date to hand in my final draft is aug 30th!

🌻 tomorrow night, mischa and i will be flying to london for one last time until monday, where i'll be handing in my apt key. i'm really looking forward to hitting up brunch places, going to the saatchi gallery, and browsing brick lane market :)
