10 Things: Our Home World From Afar
“It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.” - Neil Armstrong, Apollo 11NASA Solar System Exploration

Hubble Observes a Mystery: 'Cotton Candy' Planets
"Super-Puffs" may sound like a new breakfast cereal. But it's actually the nickname for a unique and rare class of young exoplanets that have the density of cotton candy. Nothing like them exists in our solar system.Exoplanet Exploration: Planets Beyond our Solar System
Time for a Mars “close-up”! 📸
About every 26 months, the orbit of Mars makes its closest approach to Earth – and December 8 is the next time!

50 Years Ago: Apollo 17 Lights Up the Night Sky on its Way to the Moon
The sixth and final Apollo Moon landing mission began with the Dec. 7, 1972, launch of Apollo 17. In the first night launch of the American human spaceflight program, the giant Saturn V rocket lifted off from Launch Pad 39A and lit up the sky at NASA…Kelli Mars (NASA)
AND there will be a rare occultation of Mars by the full moon this evening.
But I live in Ohio.
And it's raining.
😞
Of course you had to launch it at night. How else would you be able to see the moon?
And yes, I know you can see the moon during the day sometimes. But it's hard, and that makes navigation hard.
We have liftoff!

Almost all marine life depends on phytoplankton, tiny plant-like organisms that use chlorophyll to photosynthesize. Scientists track phytoplankton by measuring the concentration of chlorophyll in the water, which @nasa satellites can detect from space.
Breathing Life into the Ocean
Almost all life in the ocean depends on tiny photosynthetic organisms known as phytoplankton.go.nasa.gov
Lots of chlorophyll in the water can indicate a phytoplankton bloom, swirls of blue and green in the ocean that satellites can see from space.
The color of the swirls tells scientists about the plankton in the bloom and nutrient cycling in the ocean.
