How does spaceflight affect astronauts’ brains? There’s good news and bad (Image Credit: Space.com) Space travel is incredibly demanding on the human body, subjecting astronauts to a range of challenges: exposure to intense radiation, the effects of altered gravity, which can cause bone density loss and muscle wasting, and the toll of […]
The Sombrero Galaxy’s star-forming days are nearly over — and the James Webb Space Telescope may know why (Image Credit: Space.com) The James Webb Space Telescope’s brand-new image of the Sombrero Galaxy casts this city of stars in a new light — mid-infrared light, to be precise — and reveals clumps of […]
‘We didn’t know what it was at first.’ NASA aircraft uncovers site of secret Cold War nuclear missile tunnels under Greenland ice sheet (Image Credit: Space.com) NASA scientists conducting surveys of arctic ice sheets in Greenland got an unprecedented view of an abandoned “city under the ice” built by the U.S. military […]
NASA’s nuclear-powered Dragonfly helicopter will ride a SpaceX Falcon Heavy rocket toward Saturn moon Titan (Image Credit: Space.com) SpaceX’s powerful Falcon Heavy rocket will launch yet another high-profile NASA science mission. The agency announced today (Nov. 25) that it has picked the Falcon Heavy to loft Dragonfly, a $3.35 billion mission that […]
Neptune and Uranus have a magnetic mystery — but the case may finally be cracked (Image Credit: Space.com) When NASA’s Voyager 2 spacecraft made its way to outer regions of the solar system in the late 80’s, it noticed something odd. Both of the ice giant planets, Uranus and Neptune, lacked what’s […]
SpaceX to launch 24 more Starlink satellites from Florida early Nov. 26 (Image Credit: Space.com) SpaceX plans to launch yet another batch of its Starlink internet satellites from Florida’s Space Coast early Tuesday morning (Nov. 26).

Is Mercury in retrograde again? Yes, but there’s a catch. (Image Credit: Mashable) Mercury is a little-known, still mysterious world. But one thing is certain. Mercury, the closest planet to the sun, can’t actually travel backward in retrograde, and doesn’t impact us on Earth. The notion of Mercury retrograde, a common reference […]
Uranus’s swaying moons could help spacecraft seek out hidden oceans (Image Credit: Phys.org) Ariel, Uranus’s fourth largest moon, is thought to be made of equal parts rock and ice. A new computer model developed at the University of Texas Institute for Geophysics could be used to detect liquid water oceans beneath Ariel’s […]
