Understanding anything about a planet a billion miles from Earth is difficult.
Saturn’s core may be much bigger and “fuzzier” than previously thought, according to a new study of the planet’s rings using data from NASA’s Cassini.

Scientists in a lab used a powerful laser to re-create what might have been the original spark of life on Earth.
The researchers zapped clay and a chemical soup with the laser to simulate the energy of a speeding asteroid smashing into the planet. They ended up creating what can be considered crucial pieces of the building blocks of life.
The findings do not prove that this is how life started on Earth about 4 billion years ago, and some scientists were unimpressed with the results. But the experiment does bolster the long-held theory.
The probe has made detailed measurements of Venus’s cloudy atmosphere. Could it find life?
The Mercury-bound BepiColombo spacecraft recorded the sound of the solar wind at Venus as it flew just 340 miles (550 kilometers) above the planet’s surface during a maneuver designed to adjust its path.
The Ingenuity helicopter on Mars has now completed its 12th flight, where it acted as a scout, looking ahead for dangerous terrain for it’s partner in crime, the Perseverance rover.
The 4-pound autonomous rotocraft climbed over almost 10 meters (33 ft) high, and traveled a total of 450 meters (1,476 ft) in 169 seconds. It flew over the over an area dubbed the ‘South Seitah’ region of Mars, where Perseverance will explore.
“A dozen for the books!” said JPL on Twitter. “The Mars helicopter’s latest flight took us to the geological wonder that is the ‘South Seitah’ region.”

NASA reopened the Apollo mission control center after a complete restoration.
The goal was to transform the room back to its Apollo-era configuration.
From ashtrays to coffee mugs to clothing items…
The pencil sharpener is my favorite detail.
The universe is (nearly) 14 billion years old, astronomers confirm.
With looming discrepancies about the true age of the universe, scientists have taken a fresh look at the observable (expanding) universe and have estimated that it is 13.77 billion years old (plus or minus 40 million years).
Jupiter’s hotter-than-expected upper atmosphere may be caused by high-speed charged particles slamming into the air high above the poles.
Gravity is the weird, mysterious glue that binds the Universe together, but that’s not the limit of its charms. We can also leverage the way it warps space-time to see distant objects that would be otherwise much more difficult to make out.
This is called gravitational lensing, an effect predicted by Einstein, and it’s beautifully illustrated in a new release from the Hubble Space Telescope.
In the center in the image (below) is a shiny, near-perfect ring with what appear to be four bright spots threaded along it, looping around two more points with a golden glow.
FM radio waves reveal a side of the universe invisible to the human eye.
The most detailed radio images of galaxies outside the Milky Way have been captured by the LOFAR network of 70,000 radio antennas spread over nine European countries.
