Stars in our eyes 🤩
At the center of this image are two stars forming. Over thousands of years, they repeatedly consume, then eject the gas and dust around them. After millions of years, the pair – binary stars – will take their place in the universe. go.nasa.gov/3OFJFjP

Going goblin mode.

Within the orange-white splotch at the center of this image are 2 chaotic baby stars. Over thousands of years, the pair repeatedly gobbled up, then spat out the gas and dust around them — producing those fiery orange lobes: go.nasa.gov/3OFJFjP

Pawsitively the best astronaut portrait ever! 🐶

For his official NASA portrait in 2007, former astronaut Leland Melvin snuck his two fur babies, Jake and Scout, in to NASA's Johnson Space Center to pose with him. #NationalDogDay

Got a photo of you + space + your dog? Show us!

@lisamelton You may be cool, but you’ll never be “official astronaut portrait with your two dogs” cool.


Get in Irwin, we're going Moon driving!

Apollo 15, the 4th mission to put humans on the Moon, launched #OTD in 1971. Folded up in the lunar module (LM) was the first Lunar Roving Vehicle, allowing Dave Scott and Jim Irwin to venture farther from the LM. go.nasa.gov/43FoEKi

Oh no, what have you done? Lunar landing deniers will have an absolute field day with this photo! I can already see the red arrows pointing to the details in the back, on the ground, and, if we're lucky, also at the uncovered heads.


NASA’s Earth Applied Sciences Disasters program has been activated in support of the fires in Greece. go.nasa.gov/3Q8xwF2

Water is essential for life as we know it. However, we don't know how it reached the Earth and whether the same processes could seed planets orbiting distant stars. Now, @NASAWebb has measured water vapor in a planet-forming disk 370 light-years away. go.nasa.gov/43FDRem

Look at this big chunky weirdo. 🪨 I love it.

I spotted this boulder from a distance and have come in for a closer look. It’s harder than most, with an odd shape and makeup. #SamplingMars could be a challenge here, but I’m up for it!

Last stop! It’s time to visit one of the U.S. National Parks. 🥾🌲

Which would you rather check off your bucket list– Bryce Canyon National Park (left) or Acadia National Park (right)?
#NASAEarth

in reply to NASA

I am lucky enough to have visited both Acadia & Bryce Canyon. Both are beautiful in amazingly different ways. I would love to see both again!

Phew, that was a tough but beautiful hike! Let’s cool off in a lake. 🏊

Which would you rather dive into – this trio of lakes in Ethiopia (left) or China’s Poyang Lake (right)?
#NASAEarth

in reply to NASA

The two Ethiopian lakes on the left are alkaline lakes and infested with schistosomiasis, so I'll pass. Lake Langano is on the right is free of the parasite and is a popular tourist destination.

Poyang Lake has just entered it's earliest dry season on record (records began in 1951). Doesn't look inviting.

Today we’re taking a vacation with #Landsat! 🏖️

would there be any way to see what this would look like in light visible to the human eye? This looks incredible! I wonder if it would look just as incredible if we were there to see it. 🤔


Plants and vegetation are abundant along Baugh Creek in Idaho, thanks to the ponded water from beaver dams! 🦫

A @nasa-supported effort is using @nasa satellite data to predict which streams can support beavers and monitor changes once they return. go.nasa.gov/3Y5eRf8

All the images are showing as "Not available." If you know about it, that's fine. But if unintentional, please fix ☺️ .


Now, Landsat Next is on the horizon 🌅

With a trio of smaller satellites that can each detect 26 wavelengths of light and thermal energy,
@nasa/@USGS #Landsat Next will provide finer resolution and more frequent data to monitor Earth’s changing surface. go.nasa.gov/3va23GU

Together, OLI and TIRS study all parts of Earth’s surface every 16 days.

From land to ice to sea, the open data provided by the #Landsat program has contributed to a deeper understanding of our changing planet. #OpenScience

The @NASAKennedy launch team recently completed the first of many mission simulations for #Artemis II, the first crewed Artemis mission.

.@NASAWebb detected water vapor around a distant star in a region where rocky planets could be forming. This steamy environment raises the question: Where did the water come from? Pore over the details:
go.nasa.gov/3KaVlbo
#NASA
#NASA
in reply to NASA

It's also possible that water vapour may have evaporated from a planet that once resembled earth but has dried to a rocky desert, like Mars.
We may be witnessing the aftermath of catastrophic climate change in that region.


#Landsat 8 and 9 also measure land surface temperature with Thermal Infrared Sensor (TIRS) and TIRS-2. These data are crucial for water management and ice detection.

#DYK that TIRS almost didn’t exist? Now it’s been imaging Earth for over a decade! go.nasa.gov/3OSCDbH
#NASAEarth



Both Landsat 8 and 9 have optical sensors that collect beautiful images of Earth. 😍 🌏

Called the Operational Land Imager (OLI) and OLI-2, these sensors take measurements in the visible, near infrared, and shortwave infrared portions of the electromagnetic spectrum.
