Are new physics needed to explain the expansion of the universe? Using the power of two space telescopes, astronomers made the most precise measurement to date of the universe’s expansion rate. The results ended up fueling a cosmic conundrum: https://go.nasa.gov/2Ne8osK pic.twitter.com/JOM2lMDxQA

What happened on @Space_Station this week? @AstroSerena conducted research to combat cancer, a cargo vehicle arrived to space less than four hours after launch and lots more: https://youtu.be/ymxzfJmUO0w . Ask ?s using #SpaceToGroundpic.twitter.com/HSQiHjofej

What’s better than seeing a double rainbow? A rare double asteroid! New observations have revealed that an asteroid discovered last year is actually two objects, each about 3,000 feet in size, orbiting each other. Get the details: https://go.nasa.gov/2KTMONB pic.twitter.com/XG7IJkCVE6

Chemical Space Gardens is not only a really awesome band name, it’s cool @ISS_Research happening on @Space_Station right now! Get the details on these colorful crystal gardens currently taking shape in microgravity: https://nasa.tumblr.com/post/175823714144/chemical-space-gardens …pic.twitter.com/MCAyCInEuT

“I look forward to working with Mr. Morhard upon his confirmation,” says @JimBridenstine about POTUS’ intent to nominate James Morhard as our deputy administrator. Statement: https://go.nasa.gov/2NbizOV pic.twitter.com/GOpbeyrfAh

As Tropical Storm Chris was strengthening into a short-lived hurricane, one of our @NASAEarth satellites studied the storm’s rainfall & cloud height. This info improves @NASAHurricane scientists’ ability to evaluate how storms change in intensity over time https://go.nasa.gov/2N9aVEw pic.twitter.com/OORZlJHFt4

New Episode Alert! Tune in at 2pm ET to watch a specially curated show with some of our most exciting missions, discoveries and more: https://www.nasa.gov/nasatv pic.twitter.com/uVrwIJ6J9o

HAPPENING NOW: Ask our experts anything on reddit about a new first — identifying a monster black hole in a far-off galaxy as the source of a high-energy neutrino. Our scientists are taking questions on @reddit: https://go.nasa.gov/2KR20uS pic.twitter.com/lwqzbWsHdG

High-energy neutrinos are hard-to-catch particles that scientists think are created by the most powerful events in the cosmos. For the 1st time ever, scientists using @NASAFermi have found the source of one of these zippy neutrinos from outside our galaxy: https://go.nasa.gov/2N7HqmI pic.twitter.com/SsjghIe2Yi

For the first time ever, scientists using @NASAFermi & @NSF’s @UW_IceCube found the source of a high-energy neutrino from outside our galaxy. Join us for a @reddit_AMA at 12:30 pm ET to ask questions about this discovery: https://go.nasa.gov/2NatVm9 pic.twitter.com/gF06XbA3tJ

For the 1st time, scientists using @NASAFermi & @NSF’s @UW_IceCube have found the source of a high-energy neutrino from outside our galaxy! This tiny particle that travels at nearly the speed of light, cruised 3.7 billion yrs before being detected at Earth https://nasa.tumblr.com/post/175815835364/using-all-of-our-senses-in-space …pic.twitter.com/vVDs82VTSt

We’re inviting social media users to apply to see a rocket launch! The launch will kickoff a mission to measure the height of our home planet, with a focus on tracking changes to the ice sheets, glaciers and sea ice of Earth’s polar regions.

Are we alone in the universe? @NASAWebb Space Telescope will help us answer one of humanity's oldest questions by studying the atmospheres of distant worlds orbiting nearby stars and identifying those that could potentially support life.

.@NASAJuno has been revealing Jupiter's secrets ever since its arrival in July 2016. From finding Earth-sized storms at the planet’s poles to uncovering mysteries about the Great Red Spot, this mission is turning theories about how Jupiter works inside out https://nasa.tumblr.com/post/175746825774/solar-system-10-things-two-years-of-juno-at …pic.twitter.com/SLrfyCXUZH
