Are We Missing Alien Signals? Space Weather, Brain Changes and the Mars Life Question  
Podcast: Astronomy Daily: Space News Updates

Description: In today's episode, Anna and Avery explore five of the week's most compelling space and astronomy stories: a new SETI Institute study suggesting stellar space weather could be scrambling alien radio signals before they even leave their home systems; groundbreaking research revealing that spaceflight physically shifts and deforms the human brain inside the skull; the impressive engineering story behind Roscosmos restoring Baikonur's launch pad in record time ahead of the Progress MS-33 mission; a surprising new finding from Nature that Earth's elliptical orbit plays a much bigger role in shaping El Niño and global weather patterns than previously thought; and the endlessly fascinating question of whether asteroid impacts could allow microbes to travel between planets — including the possibility that life on Earth may have originated on Mars.   Stories Covered •       Why SETI may be missing alien radio signals — space weather around distant stars could be smearing narrowband signals beyond the reach of current detectors (SETI Institute, March 2026) •       Spaceflight physically shifts and deforms the brain inside the skull — new MRI study of 26 astronauts published in PNAS reveals extent of microgravity's neurological impact (University of Florida, March 2026) •       Baikonur's Site 31/6 launch pad fully restored after November 2025 damage — over 150 workers complete repairs in under two months, clearing path for Progress MS-33 on March 22 (NASASpaceFlight, March 2026) •       Earth's distance from the Sun found to dramatically alter seasons — new Nature study shows orbital eccentricity drives its own annual cycle in the Pacific cold tongue, influencing El Niño over millennia (UC Berkeley, March 2026) •       Did Earth life begin on Mars? New research examines how asteroid impacts could allow microbes to travel between planets via ejected rock (Universe Today, March 2026)   Connect With Us Website: astronomydaily.io Twitter/X, Instagram, TikTok, YouTube, Tumblr: @AstroDailyPod Part of the Bitesz.com Podcast NetworkBecome a supporter of this podcast: https://www.spreaker.com/podcast/astronomy-daily-space-news-updates--5648921/support.Sponsor Details:Ensure your online privacy by using NordVPN.
