A new batch of images recently arrived at Earth from JunoCam, the visible light camera on board the Juno spacecraft at Jupiter. The camera has provided stunning views of the gas giant world since the spacecraft’s arrival in 2016. Citizen scientists and imaging enthusiasts act as the camera’s virtual imaging team, participating in key steps of the process by making suggestions of areas on Jupiter to take pictures and doing the image editing work.
This lead image, edited by Kevin Gill, is another stunner: a look straight down into a giant storm.
And we like Kevin’s attitude about this whole process:

We bid a reluctant but truly fond farewell today to Michael Collins. The NASA astronaut passed away at the age of 90 on April 28, 2021. Collins flew on the historic Apollo 11 mission in 1969, and also on Gemini 10 in 1966.
As Command Module Pilot, Collins was the lone member of the Apollo 11 crew who remained in orbit while his fellow astronauts became the first to land and walk on the Moon. But his endearing nature means he will be most remembered for his wit and humor, his passion and humbleness, his unflappable demeanor, his thoughtful contemplations, and the inspiring words he left behind as a writer of several books.

As the New Horizons spacecraft hurtles out towards interstellar space, it has now reached an historical milestone. On April 17, 2021, New Horizons passed 50 astronomical units, or 50 times Earth’s distance from the Sun. It is just the 5th spacecraft to reach that distance, joining the Voyagers 1 and 2 and the Pioneers 10 and 11.

NASA pulled off a Wright Brothers moment on Mars early today by successfully flying the tiny Ingenuity helicopter for approximately 40 seconds.
“We can now say that human beings have flown a rotorcraft on another planet,” said MiMi Aung, Ingenuity’s lead engineer, speaking to her colleagues gathered at the Jet Propulsion Laboratory (JPL) in California to execute and monitor the flight.

The effects of ancient asteroid impacts on Earth are still evident from the variety of impact craters across our planet. And from the Chelyabinsk event back in 2013, where an asteroid exploded in the air above a Russian town, we know how devastating an “airburst” event can be.
Now, researchers in Antarctica have discovered evidence of a strange intermediate-type event – a combination of an impact and an airburst. The event was so devastating, its effects are still apparent even though it took place 430,000 years ago.

Whenever I wipe the dust off my coffee table or catch a glimpse of dust motes floating in sunlight, my spacey mind always wonders, is any of that cosmic dust?
It just might be. But the amount of space dust that lands on our planet every year might surprise you.

Perseverance is having a proud parent moment in this image, looking like it’s waiting with a child at the bus stop on the first day of school.

Did the Perseverance rover capture a rainbow on Mars? This image, from the rover’s left rear Hazard Camera, sure looks like it. But alas, no. However, film director JJ Abrams would be proud.

If you’re looking for doomsday, you can forget about asteroid Apophis. The latest radar observations have effectively ruled out any possibility of this near-Earth object (NEO) hitting Earth for the foreseeable future.

Here are a few stunning views of the Curiosity Rover’s current location, Mont Mercou in Gale Crater on Mars. This towering outcrop provides a great look at layered sedimentary rock structures. On Earth, it’s common to find layered rock like the ones within this cliff face, especially where there were once lakes. The pancake-like layers of sediment are compressed and cemented to form a rock record of the planet’s history.
This color image is from one of our favorite image editors, Kevin Gill. He assembled 202 raw images taken by MSL’s MastCam between sols 3057 and 3061. You can see Kevin’s full mosaic on Flickr.
