This week, Venus – the brightest planet and dazzling “evening star” – will pass the beautiful Pleiades star cluster, also known as the Seven Sisters. Look west after sunset! Venus and the Pleiades meet only every 8 years. Photos here.
The moon swept past the morning planets last week, and the EarthSky Community did a great job capturing each day’s view. Thanks to all who contributed photos to EarthSky Community Photos and to our Facebook page!
We’re between the extremes now, in a place of balance, near an equinox. This composite image shows how the sun moves along your horizon each day at sunset and sunrise, as Earth moves in orbit around the sun.
Juno arrived at Jupiter in 2016. It’s in a 53-day orbit around the planet. Close sweeps past the planet are called “perijoves” (peri means “near”). Here are some spectacular images from the most recent sweep, Perijove 25, in February.
This just in … a new super-cool composite from Curiosity on Mars. The panorama contains more than 1,000 images taken last Thanksgiving and assembled over the past few months … 1.8 billion new pixels of Martian landscape!
An intense storm and lake-effect snow walloped upstate New York – especially rural areas in western New York – in late February 2020. On the shores of Lake Erie, the storm created a dramatic display of thick, windblown ice on homes and buildings.
These hot, dust-laden winds are known as “la calima” and happen most often in winter. They can blow at up to 75 mph (120 kph). The dust kicked up last weekend in Africa drifted over the Canary Islands, shutting down airports and stranding travelers.

The moon will cover Mars 5 times in 2020, but the occultation on February 18, 2020, was the only one accessible to viewers in much of North and Central America. Photos from the EarthSky Community here.

The European Southern Observatory’s Very Large Telescope is in northern Chile. Astronomers used it to capture the unprecedented dimming of Betelgeuse, a red supergiant star in the constellation of Orion. The new images show how the apparent shape of this star is changing.

This image is part of a wider system of depressions that spiral outward from the very center of Mars’ north pole. Seen in context, you can see rippling troughs that curve and bend and slice outwards from the pole counterclockwise.
