ESA’s Jupiter Icy Moons Explorer (Juice) is coming back to Earth.
Our fearless traveller is getting a nudge from Earth this summer, in the first of four ‘gravity assist manoeuvres’ that will put Juice on precisely the right path to arrive at Jupiter with the correct speed and direction in July 2031.
This is the second big milestone in Juice’s journey to Jupiter, with the first being the launch into space on 14 April 2023. This second helping hand takes a very different form, with Juice flying past the Moon on 19 August, lining it up to fly past
Two meteor showers will flash across the sky around the same time in late July

Get ready for a meteor shower doubleheader.
The Southern Delta Aquariid meteor shower peaks in late July. And this year, it will coincide with a second smaller meteor shower, the Alpha Capricornids.
The Delta Aquariids occur every year in North America's late summer. This year's peak activity happens early Tuesday morning, with an expected 15 to 20 meteors visible per hour in the Northern Hemisphere, under dark skies. Viewing should be even better in the Southern Hemisphere. The shower lasts through August 21, according to the American Meteor Society.
Around the same time, the Alpha Capricornid meteor shower should produce around five meteors per hour and lasts through August 15.
Here's what to know about the Delta Aquariids and other meteor showers.
What is a meteor shower?
Multiple meteor showers occur annually and you don't need special equipment to see them.
Most meteor showers originate from the debris of comets. The source of the Delta Aquariids is thought to be from the comet 96P/Machholz. The Alpha Capricornids originate from the comet 169P/NEAT.
When rocks from space enter Earth's atmosphere, the resistance from the air makes them very hot.

Sun's Impact on Earth's Deep Interior Uncovered by Researchers
Sunday, 28 July 2024 23:31 Write a comment
Scientists have long held that deep Earth processes such as volcanic eruptions and tectonic plate movements primarily shape surface conditions, driving events like the mass extinction 66 million years ago and climate transitions. However, a new study in Nature Communications reveals that solar radiation also penetrates deep into the Earth's interior.

NASA's Perseverance Mars rover has made what could be its most astonishing discovery to date: possible signs of ancient life on the Red Planet.
The six-wheeled robotic explorer came across an intriguing, arrow-shaped rock dubbed "Cheyava Falls" that may harbor fossilized microbes from billions of years ago, when Mars was a watery world.

The surface of Uranus' moon Ariel contains substantial carbon dioxide ice, particularly on its trailing hemisphere, the side that faces away from its orbital motion. This is unexpected as carbon dioxide, even in the distant Uranian system-20 times farther from the Sun than Earth-easily sublimates into gas and escapes into space.
Researchers propose that the carbon dioxide on Ariel's surfac
