Cassini Views Enceladus Up-Close — NASA source Saturn’s ice-covered moon Enceladus may host a subsurface ocean with biologically relevant chemistry. Plumes released from this ocean preserve information on its chemical
The distribution of the ∼ 74 million hits from this survey across drift rate. Note the peak of hits around 0 Hz/s (expected because most RFI transmitters are in the
With the International Space Station (ISS) set to retire in 2030, several nations and commercial space companies have plans to deploy their own successor stations. This includes China, which plans
In this episode of Space Minds, host David Ariosto speaks with Juan Alonso — CTO and Co-founder of Luminary Cloud and professor at Stanford University — about the
Astronomers using NASA’s Hubble Space Telescope have imaged the largest protoplanetary disk ever observed circling a young star. For the first time in visible light, Hubble has revealed the disk
More than a billion years ago, in a shallow basin across what is now northern Ontario, a subtropical lake much like modern-day Death Valley evaporated under the sun’s gentle heat,
The shape of the universe is not something we often think about. My colleagues and I have published a new study that suggests it could be asymmetric or lopsided, meaning
https://earthsky.org/upl/2025/12/sun-cme-inflow-parker-solar-probe-december-2025-ezgif.com-resize-video.webm These images of our star’s solar wind, captured by NASA’s Parker Solar Probe, show a phenomenon called an inflow occurring in the sun’s upper atmosphere. This is where solar
The James Webb Space Telescope (JWST) was involved in yet another first discovery recently available in pre-print form on arXiv from Cicero Lu at the Gemini Observatory and his co-authors.
