Happy June solstice! Longest day for the Northern Hemisphere. Shortest day for the Southern Hemisphere. Either way … a good time to celebrate!
From the December solstice to the June solstice, the sunset makes its way north, as illustrated in this photo composite by Abhijit Juvekar. Thanks, Abhijit!
The downpour took place last weekend in parts of the U.S. Upper Midwest – Wisconsin, Minnesota and especially northern Michigan. Satellite images show the effects on Lake Superior, the largest of the Great Lakes of North America.

On June 21, 2018, at around 21:00 UTC, the sun moves out of Taurus the Bull and into Gemini the Twins. Note that we’re talking about the boundaries of astronomical constellations – not astrological “signs” – of the zodiac.
The storm is now officially “planet-encircling.” At Gale Crater, where the Curiosity rover is studying the storm’s effects, dust has starkly increased. Meanwhile, the Opportunity rover stays silent.
Two images from the Mast Camera (Mastcam) on NASA's Curiosity rover depicting atmospheric changes since a dust storm descended on Gale Crater. The left image shows the "Duluth" drill site on Sol 2058 (May 21); the right image is from Sol 2084 (June 17). Both images have been white balanced and contrast-enhanced.

Mars’ massive dust storms have been challenging – and enticing – scientists for decades. From NASA, here’s the scoop on Martian dust.
This series of images shows simulated views of a darkening Martian sky blotting out the sun from NASA's Opportunity rover's point of view, with the right side simulating Opportunity's current view in the global dust storm (June 2018). The left starts with a blindingly bright mid-afternoon sky, with the sun appearing bigger because of brightness.
Researchers found the 2 fossils in a South Australian fossil bed dubbed “Alice’s Restaurant Bed,” a tribute to the Arlo Guthrie song lyric “You can get anything you want at Alice’s Restaurant.”

Astronomers now have the 1st direct image of a black hole ripping apart a star. The star-stuff goes into a disk surrounding the hole, and it’s also ejected back to space in powerful jets.

A bit of amber preserved a drama from 100 million years ago, an interaction between a tick and a spider.
