Ice height data from @nasa’s ICESat-2 satellite and ice-cover models allowed the team to map where and how much light was penetrating through thin spots and openings in Antarctic sea ice, and how the ice moved over time.

Hang out long enough and you start to become each other…just ask these galaxies.

In Webb’s latest image, two galaxies in the process of merging are twisting each other out of shape. Bright tendrils of star-forming regions connect their glowing cores: go.nasa.gov/3OSovNB

Here are complementary Hubble & Webb views of this galactic pair. While Hubble shows the merger in visible light, Webb’s image shines in infrared. The star-forming regions in the galaxies are particularly bright in infrared light. Slide between both views: bit.ly/3FfdZwT

Is there water on the Moon? Yes, in the form of ice. Water is critical for future missions, which is why our golf cart-sized VIPER rover will explore the lunar South Pole in search of ice: nasa.gov/viper

Even baby stars burp!

Data from our retired Spitzer Space Telescope shows that young protostars can experience outbursts about every 400 years. These eruptions are a sign that the growing stars are devouring gas and dust from disks that surround them. go.nasa.gov/3gRVxkj

Mauna Loa is erupting for the first time in 4 decades, with lava flows reaching 100-200 feet in some cases.

As the volcano began erupting Nov. 27, the @nasa/@NOAA Suomi NPP satellite captured nighttime imagery of the lava’s intensely glowing light & heat. go.nasa.gov/3XDS6hX

Can they not find a virgin to toss in and appease Pepe?


As the volcano erupts, Mauna Loa is emitting sulfur dioxide (SO2), a pungent gas that reacts with oxygen and water to form a gray volcanic haze called vog.

This map shows where the @esa Sentinel-5P satellite detected sulfur dioxide with its TROPOMI sensor.

Yesterday, NASA’s uncrewed Orion spacecraft reached its max distance from Earth — 268,563 miles from Earth!

Orion will continue in its distant retrograde orbit for a few more days before swinging by the Moon again on its way back to Earth. 🌏👋🛰🌒

Orion has many cameras that it uses to capture gorgeous imagery of itself as well as Earth and the Moon at different phases and distances.

Images from its optical navigation camera help establish Orion’s position in space, a method that could be useful for future missions.

Hey @nasa, would you please provide alt text/descriptions for the photos you post on this account? I'd love to enjoy the photos like I do for the #JWST photos on Twitter.

Thanks. It's good for #accessibility for those of us who are blind or otherwise need descriptions.



In a star's life, being 100,000 years old makes one equivalent to a 7-hour-old infant. And, it turns out, they also need to 'burp' (every ~400 years). Such outbursts follow feeding frenzies, shows research that could shed light on planet formation. go.nasa.gov/3Fc6ve1

As @nasa works toward a permanent presence on the Moon, the Commercial Lunar Payload Services (CLPS) initiative, announced #OTD in 2018, is a vital part of the plan. Through CLPS, companies competitively bid to bring experiments and supplies to the Moon! go.nasa.gov/3ASxubU

Burping baby stars! (Really)

Young stars often shine in bright bursts as they consume material from surrounding disks. These luminous eruptions are signs of feeding binges as the growing stars devour material from disks of gas and dust that surround them. go.nasa.gov/3H12Tgl

Regulators, mount up! 🌟

Data from @ChandraXray and @SOFIAtelescope reveal a star cluster that regulates itself—allowing only a limited set of stars to grow before expelling most of the gas from the system. This process likely slows new star creation: go.nasa.gov/3Vz1GRg

Curious about stars? The Sun is a main sequence star, which means that it converts hydrogen into helium in its core in a process that keeps it from collapsing. It’ll become a red giant in about 5 billion years when it runs out of hydrogen. Learn more: universe.nasa.gov/stars/types/

And how many of those stars are dead? That is what trips e out the most about space is how vast it is. So vast that light's speed seems like a crawl and it dawns on you that every time you look into the sky you are looking at millions of years into the past.

1) Continental collision 2 billion years ago: Trans-Hudson orogeny (most likely explanation)
2) Ancient impact structure, but no evidence of material so not likely
3) Ancient impact crater with so much geological processes since, evidence of impact is lost.
4)Circular tectonic plate on a continent made it pull apart like a puzzle.
