Farthest Out Planetary Body We Have Ever Visited . (what a stunning image!) #mu69 #UltimaThule
After flying by the most distant object ever explored, @NASANewHorizons beamed back the 1st pictures & science data from #UltimaThule. This data is helping us understand how planets form — both those in our own solar system & those orbiting other stars: pluto.jhuapl.edu/News-Center/Ne…
#DYK water can boil and freeze at the same time? 😮 This phenomenon is called the “triple point.” The triple point is the temperature and pressure at which the three phases of a pure substance (solid, liquid and vapor) can coexist in equilibrium #Physics #FunFacts #NRCMetrology
#inatweet: screen puts out vertical polarized white light. Eyes insensitive to pol. Sunglasses block most horiz pol. Some tape is birefringent and rotates pol based on tape thickness and light colour. Different colours rotate differently thru various random tape thicknesses.
[quick note: the photon travels about twice as fast as this animation shows, same order of magnitude though so effectively close enough]
Cue a jaw-drop! 😮 Behold, our beautiful planet Earth in all its natural splendor, captured from 250 miles above by @ESA astronaut @Astro_Luca who is currently living & working on the @Space_Station. View more photos taken from the vantage point of space: go.nasa.gov/2PGmqYH
☀️Solar wind “switchbacks” 🔬Never-before-seen tiny particle events 🧹 Possible dust-free zone In August 2018, the #ParkerSolarProbe mission launched to space. Today, scientists have just announced their first discoveries from the @NASASun mission! More: go.nasa.gov/38cI3GD
Bennu and the jets? We're not sure! An unexpected discovery by @OSIRISREx revealed asteroid Bennu is ejecting particles from its surface. ✨ The mission team found 3 possible causes: meteoroid impacts, thermal stress fracturing, and release of water vapor: go.nasa.gov/33ZjoSY

.@astro_luca & I are preparing for a series of 4 spacewalks to repair the Alpha Magnetic Spectrometer, a particle physics experiment searching for antimatter to help us understand the origins of the universe. These will be very complex...it was never intended for repair in space!
My favorite payload on the #ISS is the Alpha Magnetic Spectrometer @AMSISS @AMS_02 delivered by space shuttle Endeavour. The AMS might have detected antimatter already!

Listen to the sound of Earth’s magnetic field as it’s pummeled by a solar storm
These strange new sounds underscore the complexities at play when solar storm events head for Earth.
Over the last 20 years, the atmosphere above the Amazon rainforest has been drying out, leaving ecosystems vulnerable to fires and drought, and it's primarily the result of human activities. Here's how we know and why it matters: go.nasa.gov/36Csojd 🗺: @NASAEarth
Whether it's a sci-fi thriller like Gravity or a Disney animation like Brave, physics plays a starring role in movie visual effects - find out more in our article featuring the multi-awarding winning @Framestore and @dneg ow.ly/bRhr50x1sFz
