water survival

Largest Batch of Earth-size, Habitable Zone Planets

Our Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in an area called the habitable zone, where liquid water is most likely to exist on a rocky planet.

This exoplanet system is called TRAPPIST-1, named for The Transiting Planets and Planetesimals Small Telescope (TRAPPIST) in Chile. In May 2016, researchers using TRAPPIST announced they had discovered three planets in the system.

Assisted by several ground-based telescopes, Spitzer confirmed the existence of two of these planets and discovered five additional ones, increasing the number of known planets in the system to seven.

This is the FIRST time three terrestrial planets have been found in the habitable zone of a star, and this is the FIRST time we have been able to measure both the masses and the radius for habitable zone Earth-sized planets.

All of these seven planets could have liquid water, key to life as we know it, under the right atmospheric conditions, but the chances are highest with the three in the habitable zone.

At about 40 light-years (235 trillion miles) from Earth, the system of planets is relatively close to us, in the constellation Aquarius. Because they are located outside of our solar system, these planets are scientifically known as exoplanets. To clarify, exoplanets are planets outside our solar system that orbit a sun-like star.

In this animation, you can see the planets orbiting the star, with the green area representing the famous habitable zone, defined as the range of distance to the star for which an Earth-like planet is the most likely to harbor abundant liquid water on its surface. Planets e, f and g fall in the habitable zone of the star.

Using Spitzer data, the team precisely measured the sizes of the seven planets and developed first estimates of the masses of six of them. The mass of the seventh and farthest exoplanet has not yet been estimated.

For comparison…if our sun was the size of a basketball, the TRAPPIST-1 star would be the size of a golf ball.

Based on their densities, all of the TRAPPIST-1 planets are likely to be rocky. Further observations will not only help determine whether they are rich in water, but also possibly reveal whether any could have liquid water on their surfaces.

The sun at the center of this system is classified as an ultra-cool dwarf and is so cool that liquid water could survive on planets orbiting very close to it, closer than is possible on planets in our solar system. All seven of the TRAPPIST-1 planetary orbits are closer to their host star than Mercury is to our sun.

 The planets also are very close to each other. How close? Well, if a person was standing on one of the planet’s surface, they could gaze up and potentially see geological features or clouds of neighboring worlds, which would sometimes appear larger than the moon in Earth’s sky.

The planets may also be tidally-locked to their star, which means the same side of the planet is always facing the star, therefore each side is either perpetual day or night. This could mean they have weather patterns totally unlike those on Earth, such as strong wind blowing from the day side to the night side, and extreme temperature changes.

Because most TRAPPIST-1 planets are likely to be rocky, and they are very close to one another, scientists view the Galilean moons of Jupiter – lo, Europa, Callisto, Ganymede – as good comparisons in our solar system. All of these moons are also tidally locked to Jupiter. The TRAPPIST-1 star is only slightly wider than Jupiter, yet much warmer. 

How Did the Spitzer Space Telescope Detect this System?

Spitzer, an infrared telescope that trails Earth as it orbits the sun, was well-suited for studying TRAPPIST-1 because the star glows brightest in infrared light, whose wavelengths are longer than the eye can see. Spitzer is uniquely positioned in its orbit to observe enough crossing (aka transits) of the planets in front of the host star to reveal the complex architecture of the system. 

Every time a planet passes by, or transits, a star, it blocks out some light. Spitzer measured the dips in light and based on how big the dip, you can determine the size of the planet. The timing of the transits tells you how long it takes for the planet to orbit the star.

The TRAPPIST-1 system provides one of the best opportunities in the next decade to study the atmospheres around Earth-size planets. Spitzer, Hubble and Kepler will help astronomers plan for follow-up studies using our upcoming James Webb Space Telescope, launching in 2018. With much greater sensitivity, Webb will be able to detect the chemical fingerprints of water, methane, oxygen, ozone and other components of a planet’s atmosphere.

At 40 light-years away, humans won’t be visiting this system in person anytime soon…that said…this poster can help us imagine what it would be like:

Tony Stark survives an explosion created by his own hands a few feet away from him with only shrapnel in his chest, survives chest surgery with no drugs to numb the pain, survives torture and waterboarding while having a car battery attached to his chest, survives the walk through the desert with no water, survives the climatic ending explosion, survives palladium poisoning, survives race car crash with only scrapes and bruises, survives god nearly strangling him, survives flying a nuke into space with no oxygen, survives multiple panic attacks, survives house exploding around him, survives snow and freezing temperatures in a shirt and pants, survives experimented human torches attacking him, survives climatic ending battle, survives battle against multiple buggy iron suits, survives thunder god nearly strangling him, and survives direct hit from the winter soldier.

All without his suit. 

Tell me again are we really sure Tony is just a normal very intelligent citizen and doesn’t secretly carry some form of recreated supersoldier serum that Howard probably experimented on him with. Because otherwise Tony Stark is a helluva tough guy.

Fun Facts About Honey

- Honey is mostly sugar (WoW!) it is 80% sugar and 20% water (double WoW!)

- There are over 20,000 species of bees, but only 4 make HONEY

-Honey is the ONLY food that contains all the substances you need to survive (Including WATER)

-Children under the age of 1 should not eat honey… why? because sometimes it contains bad stuff called botulism and can cause them to get botulism poisoning (that sucks, even infants should taste the deliciousness that is honey)

-Honey will crystallize under optimum temperatures (this has a lot to do with how you store it)

-Bees produce honey to eat during the winter when there are no flowers and no nectar for them.

-A honeybee would only need an ounce of honey to be able to fuel a flight around the world (this makes for a very cultural bee!)

-A typical beehive can make up to 400 pounds of honey a year! (Wowza!)

im really amazed at how u manage to run an entire webcomic, do commissions, and draw fanart, and still like. live and exist as a human being? despite being homeless and mentally ill? like you do so much in the face of so many obstacles u are just such a strong and capable person and im a little in awe

ahhh.. thank you so much for the nice message;.. I’m not in the streets right now… I’m in my aunt’s basement. Which is.. still no home, but it’s shelter nevertheless.. it’s a 10x5 feet room and it’s very cramped. I earn a little by doing her housework, She’s very?? Unstable and she keeps kicking me out so it’s very bleh on my mental well-being, I’m constantly worried she’ll have another tantrum. I do commissions because I really need to save up so I can maybe get my own place someday;;  It’s the only thing giving me energy tbh..And my comic is some sort of coping mechanism, labor of love kind of things. My mental illness tends to go haywire when I’m not doing anything.. When I was in college I used to lie in bed all day and just. Depression really prevents me from working sometimes, it makes me lethargic and sucks out all my energy but, sometimes you just have to get up and help yourself;; 

Take proper care of your air plants (tillandsia)! Despite the fact that they don’t need to be planted or watered in a traditional way, they Do. Not. Survive. Without. Water.

But fear not, because proper care is super easy! Simply submerge your tillandsia into a bath of water for 15 minutes, once a week. For me, Saturday’s are the day; my tillandsia take a bath, my succulents sit on a windowsill eating up rays, and there’s usually a cactus party in my kitchen sink.

And once you’ve bathed your lovely air plants, set them on a towel upside down so that all the water can drain out. This keeps mold & rot from growing inside the folds of the leaves.

And there ya go! Super easy! :)

(NOTE: for those interested, the big guy in the picture is my Tillandsia Xerographica at size medium! Amazing specimen!)

Now,

There are so many similes for this. Depression
makes me heavy like an overstuffed freezer.

Makes me want to sink like a razor in a river.
Wants me to unload my troubles on someone

I trust like a dishwasher. Gets me to speak
like a sea-storm warning. Tries to break me

like the faucet nobody likes. Gets me to spend
all my time in the bathtub like this is how I live now.

(I am.)
(I will.)
(I don’t.)
(I am.)
(I am.)
(I do.)
