Italy’s Mount Etna, Europe’s most active volcano, has recently been on explosive form, with 17 eruptions in less than three months. Instruments onboard three different satellites orbiting Earth have acquired imagery of the eruptions – revealing the intensity of the lava-fountaining eruptive episodes, known as paroxysms.

SpaceX launched 60 more of the company's Starlink Internet communications satellites into orbit from Florida on Wednesday. A Falcon 9 rocket carrying the spacecraft lifted off as planned at 12:34 p.m. EDT into a blue April sky with few clouds. "Falcon 9 has successfully lifted off from Cape Canaveral Space Force Station carrying our stack of Starling satellites to orbit," SpaceX

Enabling the Mars Rover's core operations in the harsh environment on Mars are Kaydon RealiSlim thin-section ball bearings, designed and manufactured by SKF at the company's global thin-section bearing engineering center in Muskegon, and its recently expanded manufacturing hub in Sumter, USA. These highly engineered components contribute to the survival of the rover's main robotic arm, sam

Astronomers have found evidence that the first exoplanet that was identified transiting its star could have migrated to a close orbit with its star from its original birthplace further away. Analysis of the planet's atmosphere by a team including University of Warwick scientists has identified the chemical fingerprint of a planet that formed much further away from its sun than it currently resid

Using data from NASA's Spitzer Space Telescope, scientists have identified the three fastest-spinning brown dwarfs ever found. More massive than most planets but not quite heavy enough to ignite like stars, brown dwarfs are cosmic in-betweeners. And though they aren't as well known as stars and planets to most people, they are thought to number in the billions in our galaxy. In a study app

Why do asteroids in the solar system have the sizes we observe? Two researchers at the Max Planck Institute for Astronomy have found an answer to that fundamental question: For the birth planets and planet precursors in our solar system 4.5 billion years ago, turbulence played a key role, helping to bring together pebble-like objects to form larger aggregations known as planetesimals. The presen

The lander and rover of the Chang'e 4 probe have resumed work for a 29th lunar day on the far side of the moon. The lander woke up at 9:43 pm Tuesday (Beijing Time), and the rover, Yutu-2 (Jade Rabbit-2), awoke at 3:54 am Tuesday, according to the Lunar Exploration and Space Program Center of the China National Space Administration. The Chang'e 4 probe, switching to dormant mode duri

NASA's Mars helicopter Ingenuity, the first powered aircraft on another planet, is free of the Perseverance rover that carried it and appears to be functioning well ahead of its first flight on Sunday, the space agency said. NASA plans to broadcast the results of that first flight at 3:30 a.m. EDT Monday after the helicopter transmits data and images to Perseverance, which will send the
