What is the meaning of the NASA logo?
The round red, white and blue insignia, nicknamed the "meatball," was designed by employee James Modarelli in 1959, NASA's second year. The round shape of the insignia represents a planet. The stars represent space. The red v-shaped vector represents aeronautics. The circular orbit around the agency's name represents space travel. #nasa#nasa60th 📸 @nasa
È stato l’astronomo tedesco Johann Gottfried Galle a scoprire, ben 169 anni fa il pianeta a cui venne dato il nome del dio greco del mare: Nettuno.
Si tratta, escludendo i “pianeti nani”, come Plutone, Sedna ed Eris, del pianeta che è stato scoperto per ultimo. E’ l’ottavo in base alla distanza dal Sole, il quarto per lunghezza del diametro e il terzo in riferimento alla massa.
Johann Gottfried Galle, assistito dal ricercatore Heinrich Louis d’Arrest, individuò Nettuno dall’osservatorio di Berlino proprio il 23 settembre del 1846. La scoperta non avvenne attraverso l’utilizzo di regolari osservazioni celesti, ma fu frutto soprattutto di complicati calcoli matematici, basati sui precedenti studi di Urbain Le Verrier. Le osservazioni con il telescopio che confermavano l’esistenza di un pianeta iniziarono la notte del 23 settembre e finirono al mattino del 24. Fu un evento straordinario. Una scoperta condotta con un metodo innovativo e che venne considerata come la conferma della teoria gravitazionale di Isaac Newton. Come disse in seguito François Arago, era stato scoperto un pianeta “con la punta della penna”.

Equinox: Analemma over the Callanish Stones
Does the Sun return to the same spot on the sky every day at the same time? No. A more visual answer to that question is an analemma, a composite image taken from the same spot at the same time over the course of a year. The featured analemma was composed from images taken every few days at 4 pm near the village of Callanish in the Outer Hebrides in Scotland, UK. In the foreground are the Callanish Stones, a stone circle built around 2700 BC during humanity's Bronze Age. It is not known if the placement of the Callanish Stones has or had astronomical significance. The ultimate causes for the figure-8 shape of this an all analemmas are the tilt of the Earth axis and the ellipticity of the Earth's orbit around the Sun. At the solstices, the Sun will appear at the top or bottom of an analemma. Equinoxes, however, correspond to analemma middle points -- not the intersection point. Today at 1:54 am (UT) is the equinox ("equal night"), when day and night are equal over all of planet Earth. Many cultures celebrate a change of season at an equinox.
SpaceX Recently announced their 3rd and final design update for the BFR, or Big Falcon Rocket. This is the version that will take humans to Earth orbit, the moon, and even to mars! It will be able to carry 100 tons to anywhere in the solar system via ISRU(In Space Refueling Unit)

Our Beautiful Doom | I found a stunning set of stock photos of icebergs recently separated from Greenland’s ice sheet and just had to make something with them. So I created a quick UI study with some interesting type and graphic elements.
However, as I put this layout together, I tried to add some informational context to it. Science is a deep love of mine, so that is the direction I took when finding some facts about icebergs and how their intense beauty often belies their impact on us.
On average, 684,931,501 tonnes of fresh water melts off of Greenland’s ice shelf every day, according to the most recent reports that I could find, published by #nasa in 2017. This staggering amount of water, much less fresh water, affects the habitability of our oceans for marine life, raises sea levels at ever increasing rates, and affects weather patterns by changing water temps, which we feel through the increasing severity of our hurricane season.
It is caused by and an accelerator of climate change. This is not a partisan issue. It is not a religious issue. It is science. It is not driven by nationalism, capitalism, or belief. It is a theory that has been tried, tested and confirmed by thousands of scientists over decades of study.
If you love anything about this world this should matter to you, because it has the power to drastically alter the world and the way we as humans relate and survive within it.
Güneş aynı günde her gün aynı noktaya dönüyor mu? Hayır. Bu soruya daha görsel bir cevap, bir yıl boyunca aynı noktadan aynı noktadan alınan kompozit bir görüntüdür. Öne çıkan analem, İskoçya, İngiltere'deki Outer Hebrides'deki Callanish köyünün yakınlarında öğlen saatlerinde çekilen görüntülerden oluşuyordu. Ön planda, insanlığın Bronz Çağı'nda M.Ö. 2700 civarında inşa edilmiş bir taş daire olan Callanish Stones vardır. Callanish Stones'in yerleştirilmesinin astronomik önemi olup olmadığı bilinmemektedir. Tüm bu analemmaların şekil-8 şekli için nihai nedenler Dünya ekseninin eğimi ve Dünya'nın Güneş etrafındaki yörüngesinin eliptikliğidir. Gündönümünde, Güneş bir analeminin en üstünde veya altında görünecektir. Bununla birlikte, ekinokslar, kesişme noktasını değil analemma orta noktalarına karşılık gelir. Bugün saat 1:54'te (UT), ekox ("eşit gece"), gündüz ve gece, Dünya gezegeninin tümünde eşit olduğunda. Birçok kültür, bir ekinoksta mevsim değişikliğini kutluyor. Yarının resmi: Güneşin parçaları eksik

Come visit the NASA Exhibit from NASA’s Johnson Space Center today at Centerplace from 11am - 3pm! ⠀
We are celebrating Spokane native, astronaut Anne McClain, and her journey to the International Space Station which will begin in December 2018. #spokvalleyfest#NASA
Wow. Beakernight 2018 was a SUCCESS friends 🤩🤖🔥 !!! A little cold and rain can’t stop Beakerfans 🤟🏿👩🏻🔬 Thanks to everyone that celebrated science, art and engineering last night 💥🎟⚗️ TODAY is the last day of #beakerhead so sprint to see the installations before they are taken down! Thank you @kryoman for coming out 🤖😍.
This photo of the day comes from @persuasionphoto 🎉📸🧠💎🖤 #beakernight
WHAT’S OUT THERE? 🌌Our newest planet-hunting spacecraft — the Transiting Exoplanet Survey Satellite, or TESS, just released its first science image using all four cameras on the spacecraft! Swipe through to see the first full swath of sky that TESS captured in its search for planets outside of our solar system, called exoplanets.
This “first light” image, taken in one 30-minute period on Tuesday, Aug. 7, captured a bounty of stars and other objects, including systems previously known to have exoplanets. They cover a band of the southern sky that captures parts of a southern dozen constellations, from Pictor (the Painter’s Easel) in the first image to Capricornus (the Sea Goat) in the last image. However, it might be hard to find familiar constellations among all these stars!
In the first and second images, you’ll find the Milky Way’s closest neighbor galaxies, the Large and Small Magellanic Clouds. The small bright dot to the right of the Small Magellanic Cloud is a globular cluster — a spherical collection of hundreds of thousands of stars — called 47 Tucanae because of its location in the constellation Toucana (the Toucan). In the first and third images, there are also two stars so bright to TESS’s cameras that they saturate an entire column of pixels on the cameras' digital sensors, resulting in long horizontal lines.
Led out of the Massachusetts Institute of Technology, TESS is expected to find thousands of new exoplanets. It will scan nearly the entire sky over two years to monitor 200,000 of the nearest and brightest stars in search of transits – periodic dips in a star’s brightness caused by planets passing in front of their stars.

Fun fact #91
This is how a hurricane from the space looks like
nasaA storm is brewing! 💨
Earlier this morning, @astro_ricky shared this view of Hurricane Florence while orbiting our home planet from 250 miles above. As one of six humans living and working aboard the International Space Station (@ISS), he takes in 16 orbits of Earth each day at a speed of 17,500mph.
In addition to space views captured by our astronauts, our @NASAEarth-observing satellites collect imagery and data, including infrared and microwave imagery, rain rates throughout the storm and cloud heights. This data helps scientists and forecasters better predict weather and keep the public informed.
