Kick off the weekend with a relaxing view of the tranquil galaxy UGC 12295.

Shining in this new #HubbleFriday image, UGC 12295 is 192 million light-years away in the constellation Pisces.

This is one HARD rock! I gave it a go with my coring drill, but it seems this one doesn’t want to give up all its secrets. Still, I can study it more with my science instruments and use my drill next time. Sometimes the better part of perseverance is knowing when to move on!

My newborn also had a tendency to squirt out of both ends, so I guess it's just a universal constant 🙃



The data from STAQS will complement new measurements from NASA’s TEMPO satellite, which measures hourly daytime air pollution over North America.

TEMPO launched in April 2023. 🛰️ go.nasa.gov/45586w6
#NASAEarth



The STAQS team is tracking where air pollutants come from, how they change hour by hour, and which neighborhoods are disproportionately exposed to unhealthy air. go.nasa.gov/3rQuStC
#NASAEarth


From city street to stratosphere 🏙️🛫🛰️

This summer, @nasa’s STAQS mission is mapping air pollution in 3D across several megacities: New York City, Chicago, Los Angeles and Toronto. go.nasa.gov/3rQuStC

💥 @NASAHubble catches a petulant star blasting a planet. Flares, powered by intense magnetic fields tangled by the roiling motions of the stellar atmosphere, lead to torrential winds, X-rays and more. go.nasa.gov/43Pa3Me

Well, it just keeps going around and around and around like some gnat. So yeah, sooner or later you do want to swat the damned thing.

Hiccups happen to everyone... even planets.

Hubble observed an exoplanet orbiting so close to its parent star that it experiences a consistent, torrential blast of energy, which evaporates its hydrogen atmosphere – causing it to puff off the planet: go.nasa.gov/3OzYIvm

This exo planet is the perfect example of a toxic relationship!
in reply to NASA

If a planet can get the hiccups, perhaps a planet can also catch a fever.

(Boy, it's hot outside!)

Photos of pink and gold clouds hanging over oceans around the world were captured as the space station orbited roughly 260 miles overhead.

If you're in parts of the Eastern Seabord, you might be able to see Cygnus lift off in person!

Here's when (and where) to look on Aug. 1, weather permitting: go.nasa.gov/3DuU6QP

The next cargo mission to the @Space_Station will launch from @NASA_Wallops in Virginia. Liftoff of @NorthropGrumman's uncrewed Cygnus spacecraft is set for Aug. 1 at 8:31pm ET (0031 UTC).

is that a portal cube? Follow-up question: how is the portal research going?
