A pair of galaxies resemble a waterfall in this @NASAHubble image. Interacting galaxies influence each other, which may eventually result in a merger or unique formation. Here, stars from one galaxy appear to fall into the other like drops of water: https://t.co/CA7Uw76FsQ https://t.co/8E3orn6dGx
What do Albert Einstein, GPS, & a pair of stars 200,000 trillion miles away have in common?
An effect called the "gravitational redshift” from Einstein’s General Theory of Relativity. Using @ChandraXray, astronomers discovered the phenomenon in two stars: https://t.co/fsYYh2iKj9 https://t.co/nol8Xqjxwr

RT @NASASun: It’s #SunDay — with a special guest, the Moon! Our satellite’s view of the Sun was briefly interrupted by a lunar transit on Oct. 16. At peak, the Moon covered about 44% of the Sun. https://t.co/0RETP4HFey https://t.co/V0nOGcj8D4
RT @NASAAstrobio: Asteroids are the storytellers of our solar system’s youth. This week, @OSIRISREx collected an asteroid sample & will bring its stories to Earth.
Why is it that asteroid Bennu holds the history of our origins? Let’s go back to the beginning: https://t.co/IUr41QON2t https://t.co/nz8mPJ4afU
As we are preparing for the full engine firing test for the #Artemis I mission, we’ve been asking you — yes, you! — to tell us what you would pack for the Moon.
