Earth has about 370 quintillion gallons of water, but only a tiny fraction is useable by humans. Earth’s water budget tells us where water is today, where it’s coming from, and where it’s going to be tomorrow. #WorldWaterDay

Are we using the term "useable" correctly? I think the better term might be "drinkable". After all, we USE non-potable water to buoy our ships, move our turbines, cool our reactors, and provide sport and recreation.

Sand…coarse, rough, gets everywhere. We may have found it on VHS 1256 b, a Tatooine-like world orbiting twin suns. Among other molecules, Webb detected silicate dust grains in its atmosphere. The larger grains may be like very hot, small sand particles: go.nasa.gov/40jDNje

nasa coming up to me because it loves me and is obsessed with me all like "I found a hot small sand planet for you" but when it pulls it out of its pocket it's all smeared with chocolate and granola crumbs and it tries to wipe it off on its shirt but it's too late and the sand is cold now anyway

On board was a crew of two: Commander Jack Lousma (right) had previously spent 59 days in space in 1973 with Skylab-3, but C. Gordon Fullerton (left), who had served on the support crew for Apollo missions 14 through 17, was making his first space flight.

Where will you be during the eclipses in 2023 and 2024?

This map shows the path of the Moon’s shadow as it crosses the contiguous U.S. during the eclipse on Oct. 14, 2023 and total solar eclipse on April 8, 2024. Will you get a chance to see them? go.nasa.gov/40pj5hL

On both dates, I will be watching from my backyard with my telescope, equipped with an aperture mask and proper solar filter, weather permitting, of course.

A year ago, we passed 5,000 planets confirmed beyond our solar system. We've since added more than 300 exoplanets to the total and @NASAWebb has increased what we know about many of them. We are living in an age of discovery. Exoplanets.nasa.gov

Happy that the first exoplanet discovered accidentally by Dale Frail and Aleksander Wolszczan in 1992 is included. They were not even mentioned when other #astronomers were awarded the Nobel prize for the discovery of exoplanets. And yet the discovery ended up showing exoplanets can show up in strange places.

To close out Hubble's 2023 #MessierMarathon, here's a new image of M19!

M19 is a star cluster with a slightly elongated shape. It's relatively close to the heart of our Milky Way, so the gravity from the galactic center could be stretching it: go.nasa.gov/40mqDld

The Messier catalog features beautiful stargazing sights that amateur astronomers and observatories like Hubble observe.

Not to toot my own horn, but one of the scientists who worked on this project was an SAT student of mine when he was in high school. So, you know, you're welcome!!


Depending on your hemisphere, it's the first day of spring … or fall. Either way, yay! Many exoplanets not only may not have seasons, they may be tidally locked, so the same side always faces the star, like the Moon to Earth. It's always everlasting day or never-ending night.

Previously, it was uncertain how many deaths linked to PM2.5 were associated with dust.

According to the team’s estimates, 22 percent of the premature deaths associated with PM2.5 were due to dust—much of this in a “dust belt” that spans from West Africa to East Asia.
#NASAEarth



Windblown dust and human-caused particle pollution called PM2.5 likely contributed to 2.89 million premature deaths in 2019, according to research led by @nasagoddard scientists.

If you’re in the northern hemisphere, this is an ideal time of year to spot cosmic objects from the Messier Catalog in the night sky – like the sparkling star cluster M7, seen in this new Hubble image!

M7 contains about 80 stars, loosely bound by gravity: go.nasa.gov/40mSIcq

in reply to NASA

do these globular clusters orbit around each other, or is there likely to be a black hole at the centre?


These two stars are on their own adventure!
One collapsed with such force that it was ejected from its galaxy, dragging its binary star companion out with it.

Longer days are on the horizon! ☀️ 🌸

The March equinox marks the first day of spring in the Northern Hemisphere. It's also a time when the length of day and night are nearly equal.

Today is the equinox, when the Sun is directly over the equator. Did you know other planets have seasons and equinoxes, too? On Saturn, they happen only once about every 15 Earth years. This view of an equinox in 2009 came from our Cassini spacecraft. solarsystem.nasa.gov/resources…

🌸 Ok, bloomer: Spring is here. The March equinox marks the first day of spring in the Northern Hemisphere and autumn in the Southern Hemisphere. During equinox, the Sun shines on the equator with nearly equal amounts of day & night: go.nasa.gov/40hcGVO
