Starting from #Asteroids and #Exoplanets where we shared the Research behind our #SpaceRex project (for Asteroid Detection using #ArtificialIntelligence) and #TRAPPIST1 project (where large Resonant Chains which provide stability to this Exoplanetary system), we move to our Sun! SpaceRex project for Asteroid DetectionTrappist-1 project modeled on Harmonic Resonant Chains of the exoplanetary system
We wondered if Astronomers can find planets around stars 1000s of light years using Transit Method (dip in star's brightness because of orbiting planets) could we use this method on our parent Star- the Sun?

A unique opportunity came on 21 Aug 2017- the #TotalSolarEclipse in US Path of 21 August 2017 Total Solar Eclipse
Solar eclipses happen when Moon's shadow falls on the Earth as it passes between us and the Sun.

On 21 Aug 2017, Moon would pass between Sun and the Earth, appearing to block the Sun for almost 90 mins.

We wanted to measure dip in Sun's Brightness during this Transit Event.
Measuring Solar Eclipses have scientific value. Eg: how rapidly the Earth cools when Solar radiation is blocked.

We turned to our School Lunch Boxes to transform them into Scientific devices.

Fitted them with Sensors, Arduino, Real-time Clock, Solar Cell, SD Card to store data Fitting School Lunch box with Sensors to take measurements during Solar Eclipse
Followed by hours of Coding + Testing sensitivity of device to measure changes in: Temperature, Humidity, Visible, Ultra Violet, Infrared radiation, Solar Output and record data every second.

Our school lunch box device #SolarX was ready for deployment for #TotalSolarEclipse Solar-X ready for deploymentSensors fitted into Solar-X
We traveled to Carbondale, Illinois, USA which would experience Totality of longest duration for #2017SolarEclipse- 2min 40 sec.

We collected baseline data 2 days prior to Eclipse.

We linked with @NASAGO NASA Globe Observer and @SIUC to share our #CitizenScience data with them Testing Solar-X at Carbondale, Illinois, USA
2017 Solar Eclipse lasted 3 hours from First Contact to Last Contact.

We collected over 140,000 individual measurements using Solar-X. Also made observations pertaining to Cloud Cover every 20 minutes.

Later we downloaded the entire data for analysis. Site of Total Solar Eclipse: Carbondale, Illinois, USA

BIG💧THREAD ALERT

Yesterday I spoke about the value of freshwater ecosystems & some threats by human alteration & a changing climate.

There’s many great voices & I’ve been saving their tweets/links just for this occasion. So thank you water tweeters for sharing your insights.

Here's a thread on basic tips to help improve your next science figure! 📝 (ie common mistakes I see). It'll cover:
1) Contrast (color value) ⬛️⬜️
2) Color (it’s a tool, not decoration!) 🌈
3) Fonts 🔤
4) Image Resolution 📷
5) Spacing / margins 📐
6) By request! 💡
1a) Ahh contrast.. my favorite topic! If we lived in a world of black & white, contrast would actually be less of an issue (because we'd notice it immediately). Color variation can trick you into thinking something is legible!
1b) Left image - looks decent, but dark on dark elements getting hard to read. Right image - if converted to black and white (great trick to check contrast btw) becomes almost illegible and purple dots disappear. Bad for color blind and if figure is ultimately printed in B&W!

(1/6) This was a fun piece I illustrated with @NatGeo on the neuroanatomy of the common octopus 🐙 Seems relatively simple but (as many of you can attest) a lot of good storytelling is stripping AWAY info as opposed to adding.. (here's a peak at the process work below)
(2/6) First sketch that was proposed to me for the story. I was immediately hooked since I am fascinated with octopi 😍🐙
(3/6) Most of the work in science illustration actually goes into background research, coordinating w/ world experts (sometimes means emailing across 5 different timezones - Greenland, Australia, Canada, US, Europe...). Most times we have to go with the best 'theory' out there 🤔

Our team is a mix of scientists of many different skill sets and backgrounds. Some of us are great at tweeting, some of us are great at fixing cars, and some of us can cook a curry that makes you cry with happiness after a long windy day in the field.
What binds is together is our dedication to studying the workings of the Solar System by studying out of this world landmarks on Earth. #NASAFieldWork
Some of us are looking at ice and life in preparation for sending robots to Europa. That brought our Team Ice to The glacier covered volcano Kverkfjöll.

So a few people have been asking about general word finding difficulties and temporary episodes of language loss. Firstly, let me just say that I am not a medical doctor. 1/2
An increase in word finding difficulties can occur with age.
Temporary episodes of language loss may be called 'aphasia' by some but the cause is temporary - diff to someone who has a brain injury that changes the brain permanently (even tho they may recover to some extent). 2/2
@rudetuesday @MoiraR @tessisrelated
I hope the information in this thread helps.

So I'll start a thread that provides more information about #aphasia...
Feel free to ask any specific Qs you may have...
Aphasia is caused by an acquired brain injury, most commonly #stroke. Around 1/3 of people with left hemisphere stroke can have aphasia. Over time, the severity of the aphasia and type may change but many people live with aphasia.
Here are a couple of YouTube clips that talk more about #aphasia, posting them again here for ease of reference:


This award-winning video by @shireeheath explains aphasia from a child's perspective:
