Curiosity Rover Catches A Stunning Martian Dawn
[NASA] A newly released panorama captured by NASA’s Curiosity rover offers the most detailed view yet of distant, wind-carved Martian cliffs, highlighting features the mission’s scientists have long been waiting to see up close. The scene was snapped at 8:30 a.m. local Mars time, showing striking blue hues in the foreground as bright morning light…

Earth As A Potential Source Of Llife For Europa’s Subsurface Ocean
The paper discusses the possibility of dust particles containing living bacteria ejected from Earth reaching Europa and landing on its surface. It is shown that, taking certain factors into account, over a period of 30 − 80 Myr (the estimated age of Europa’s ocean), Jupiter’s moon would have been impacted…
Keep readingDust To Dust: Prospects For Passive Technosignatures As Relics Of ETI
Technological societies are separated in time, not just space — that is the lesson of the Drake equation. Might the best way to seek them be to find technosignatures that persist long after their creators? I present work I and my collaborators have done on the idea of passive technosignatures,…

Temporal Variability of Titan’s Middle-Atmospheric Zonal Winds from Southern Fall to Late Winter (2016-2023)
[astro-ph.EP] Previous ALMA observations have revealed unexpectedly strong and rapid variations in Titan’s high-altitude equatorial zonal winds, which present a challenge to our understanding of this moon’s atmospheric dynamics. Here we report further measurements of Titan’s zonal wind field at middle atmospheric altitudes ≈200-490 km, based on ALMA observations of spatially and spectrally resolved CH3CN…
