May's possible meteor outburst offers chance to listen to 'shooting stars' on the radio Under certain conditions, meteors can reflect radio waves in the same way the ionosphere propagates transmissions between widely separated ham-radio operators. The ionosphere usually reflects frequencies below 30 megahertz (MHz), but it's transparent to ...

Boeing's Starliner spacecraft lands in New Mexico after successful test flight Three red, white, and blue parachutes slowed the capsule to gentle landing velocity of 17.7 mph (28.5 kilometers per hour). Airbags at the bottom of the spacecraft cushioned the jolt of touchdown, ending a long-delayed demonstration mission to the ...

Soar over Mars rover tracks with Ingenuity helicopter (video) NASA's Mars helicopter Ingenuity cruised above some tracks made by its robotic partner on its most recent flight, as footage captured by the rotorcraft shows. The 4-pound (1.8 kilograms) Ingenuity conducted its 28th Red Planet flight on April 29, ...

Sunspots: What are they, and why do they occur? Sunspots are dark, planet-size regions of strong magnetic fields on the surface of the sun. They can spawn eruptive disturbances such as solar flares and coronal mass ejections (CMEs). These regions of the sun appear darker because they are cooler than ...

Ancient volcanoes may have created a rare resource for lunar explorers Ancient volcanic eruptions on the moon could provide an unexpected resource for future lunar explorers: water. Between 2 billion and 4 billion years ago, the moon was a volcanic hotspot. Tens of thousands of volcanoes ...

Tau Herculids: On May 31, A Passing Comet Could Put On the Most Dramatic Meteor Shower of Recent Times! A comet is an object made mostly of ice and dust, often with a gas halo and tail, that usually orbits the Sun. When comets orbit too close to the Earth, our gravity tends to pull fragments of it into the atmosphere. These fragments — or meteors — burn ...

New Mars study traces erosion history on the Red Planet in search for water A new study attempts to find periods of more intense erosion on Mars in hopes of understanding when water flowed on the world's surface. Water can carry larger pieces of rock into collisions, breaking the rocks faster, so accelerated erosion might be a ...
