Did the Wow! signal come from this star?

Where did the famous mystery Wow! signal, detected in 1977, come from? Astronomer Alberto Caballero might have pinpointed the host star. It’s a sunlike star 1,800 light-years away, in the direction of the center of our Milky Way.

A magnified view of Jupiter and Saturn at conjunction

On December 21, 2020, Jupiter and Saturn will be only 1/5 of a moon-diameter apart! Guy Ottewell offers insights and charts showing a magnified (telescopic) view of their once-in-20-years great conjunction.

China’s Chang’e 5 mission is orbiting the moon!

China’s robotic Chang’e 5 will be the 1st sample-return from the moon since the 1970s. It launched successfully last week atop a Chinese Long March 5 rocket. Now it’s reported to have entered orbit around the moon.

Satellite images confirm uneven impact of climate change

(Faculty of Science – University of Copenhagen) University of Copenhagen researchers have been following vegetation trends across the planet’s driest areas using satellite imagery from recent decades. They have identified a troubling trend: Too little vegetation is sprouting up from rainwater in developing nations, whereas things are headed in the opposite direction in wealthier ones. As a result, the future could see food shortages and growing numbers of climate refugees.

U.S.-European mission launches to monitor the world’s oceans

The Sentinel-6 Michael Freilich satellite will extend a nearly 30-year continuous dataset on sea level collected by an ongoing collaboration of U.S. and European satellites while enhancing weather forecasts and providing detailed information on large-scale ocean currents to support ship navigation near coastlines.

NASA Uses Supercomputers and AI to Count Earth’s Trees From Space For the First Time

To get a sense of how much carbon the Earth can store, and how it changes over time, scientists would need to count a bewildering number of trees, and track their growth over time. Incredibly, the folks at NASA are now using supercomputers to do precisely that—via top-down imaging from space. Scientists from NASA’s Goddard […]

Some Amazon rainforest regions more resistant to climate change than previously thought

(Columbia University School of Engineering and Applied Science) Is the Amazon rainforest as sensitive to water stress as what the current models have been showing? Columbia Engineering researchers found that the models have been largely over-estimating water stress in tropical forests. While models show that increases in air dryness greatly diminish photosynthesis rates in certain regions of the Amazon rainforest, observational data results show the opposite: in certain very wet regions, the forests instead even increase photosynthesis rates in response to drier air.

Tiny Spacecraft is ‘Solar Sailing’ in Orbit Using Only Sunlight, a Revolution in Space Exploration

An American astronomical society is proving that, like the Vikings of old, exploration of foreign shores—in this case foreign planets—is possible if you but master the use of the humble cloth sail. LightSail 2, designed and crowd-funded by the Planetary Society, is a small spacecraft that has been moving around at high-speeds in Earth’s orbit, […]
