Ice extent jumped to 21 percent in early February in response to a cold snap. But since then, it has declined. Maximum ice cover is usually between mid-February and early March.
Great Lakes Low on Ice
This winter, ice cover in the basin has hovered at unusually low levels.go.nasa.gov
The Great Lakes have been unusually ice-free this winter. In this image from Feb. 13, ice cover on the lake was 7 percent – the lowest ice cover measured on this date of any year since 1973 when satellite-based record keeping began.

Discovery Alert: First Six-star System Where All Six Stars Undergo Eclipses
Astronomers found the first six-star system where all of the stars participate in eclipses, a discovery made by NASA’s Transiting Exoplanet Survey Satellite (TESS). The system is about 1,900 light-years away in the constellation Eridanus.Exoplanet Exploration: Planets Beyond our Solar System

Cool, so a few questions on the pic
the red star to the right of the centre of the galaxy, is that a red giant? and to the far right of the picture there is something very bright indeed, anothr galaxy or is that a supernova as it looks brighter than the centre of the galaxy.

Scientists at the University of Utah studied how snow worsens temperature inversions and air quality.
They found that the chance that air pollution would exceed national standards increased from about 5% to 22% when there was snow on the ground.

The Salt Lake City area was covered in snow on Feb. 2, 2023, when @nasa’s Aqua satellite took this image.
At the time, @EPA data showed the air quality was above 100 on the air quality index, making it unhealthy for sensitive groups.

Improving solar cell efficiency would be a massive benefit to come from the Mars Program.
Right now, solar cells only react to one wavelength of light with the rest of the spectrum going to waste. Reacting to a 2nd wavelength would DOUBLE efficiency (producing nearly twice as much electricity.) Imagine a solar cell that reacts to the 7 primaries (ROYGBIV)? Solar cars that never need plugging in! 😵
Today's rocket launches are part of an effort to study Earth's mesosphere, the layer of the atmosphere about 31 to 53 miles (50-85km) in altitude. 🚀☁️
The mesosphere is where meteors often burn up. It has its own chemistry and winds, and is where noctilucent clouds form!
