Noctiluca, is that you?

The @nasa / @usgs #Landsat 9 satellite captured this image of swirling tendrils of phytoplankton – which appear to be Noctiluca scintillans – off the coast of Germany's East Frisia Islands on June 14, 2023. #WorldOceansMonth

NASA’s upcoming PACE satellite will allow researchers to infer more information about the oceans.

PACE will be able to determine the concentration and size of particles in seawater, diversity of phytoplankton, and rates of phytoplankton growth. go.nasa.gov/3Jryg3Y

Because the duration was mentioned, I looked up the average length of a spacewalk and saw they usually come in at around 6.5 hours. My question now is: Why?

Is it due to the extra steps required (no pun intended) for safety, the general challenge of moving in a vacuum, or because they really just wanted to get out for a bit?

Venus and the Moon setting in hazy skies over Horseshoe Springs, Utah. Mars is also visible, just to the upper left of Venus. The trio will appear even closer together in the western sky tonight. More stargazing tips: solarsystem.nasa.gov/skywatchi…

they looked amazing over my house last night. I didn’t realise it was Mars off to the left. I wish I had a better camera!


And a selfie of us all. Our Lunar Reconnaissance Orbiter captured this view of our home planet on April 21, 2017 during a total solar eclipse, with the Moon’s shadow visible over the eastern half of the US. The next total solar eclipse is April 8, 2024. go.nasa.gov/42RqRBQ

Sometimes #SamplingMars has its surprises. Hear from one of my scientists about the first sample I collected, and how we made Martian “lemonade” when Mars gave us a lemon. 🔴 🍋

El Niño is back. 🌊

On June 8, 2023 @noaa declared El Niño conditions – known for warmer than average sea surface temperatures in the tropical Pacific that can bring cooler, wetter conditions to the U.S. Southwest and drought to the western Pacific. go.nasa.gov/3JokwXH
#NASAEarth

in reply to NASA

Well it better get busy because it SURE ain't cooler, and if it's "wetter" it's just the humidity in the air. Heat index in south TX is 116F at the moment...


El Niño can be seen in sea surface height, as warmer waters pile up due to weakening trade winds, raising sea level.

This map shows sea surface height anomalies from the Sentinel-6 Michael Freilich and Sentinel-3B satellites for June 1-10, 2023. go.nasa.gov/3JokwXH

Today, #Solstice2023, is the longest day of the year in the Northern Hemisphere. For a tidally-locked exoplanet, one side always faces the star, meaning days never end. The zone between day and night is also locked in permanent twilight, seen here on Earth.

🧀 No, it’s not made of cheese, but there are many great things to digest about our Moon. It contains layers, with heavy materials like iron at its core and a surface covered in dust and rocks.

I had no idea the moon has a core! I now feel very silly.

I’ve always wanted to build my own sundial and Stonehenge style seasonal observatory given an arc and pole markers in my yard. Though local angular distances may vary, this has given me yet other ideas on how I could go about this.

Seasonal sea ice is breaking up in Canada’s James Bay. 🧊

@nasa’s Terra satellite captured this image on June 2, 2023, when little fast ice (ice fastened to the surrounding coastlines) remained. Typically, fast ice grows in December and breaks up in May. go.nasa.gov/3CDnT9l
#NASAEarth



Notice the stain?

Much of the ice is stained with sediment, which Canadian scientists say is typical and may be caused by tides stirring up sediment that gets into the ice and concentrates on the surface as the ice melts. go.nasa.gov/3CDnT9l
#NASAEarth

in reply to NASA

I suspect that this happens slowly because the sediment is not reflective like clean ice.

Sort of like Frost Lift.
