🪨 Static Electricity Is Critical to the Formation of Planets • Nautilus

｢ "The dust particles need static electricity to make them “sticky” enough to cluster into pebbles that can form planets.

Only when particles grow larger than this threshold size—roughly a quarter of an inch, depending on conditions—can they eventually join to form rocky “planetesimals,” from about half a mile to 100 miles across ｣

🪐 Protoplanetary Disks Are Smaller Than Expected • Centauri Dreams

“The discovery that the majority of the small discs do not show gaps, implies that the majority of stars do not host giant planets. This is consistent with what we see in exoplanet populations around full-grown stars. These observations link the disc population directly to the exoplanet population.”

🐈‍⬛ Black Holes May Be ‘Supermazes’ of Many-Dimensional Strings • SciAm

｢ Scientists would like an ultimate theory that can describe both the very tiny machinations of particles and the grand movements of galaxies. The insides of black holes, which are extremely small and extremely massive, are the ideal testing grounds for trying out such a theory ｣

🔭 Webb Just Captured the First Direct Image of Carbon Dioxide on an Exoplanet

｢ The achievement was made possible by Webb’s coronagraphs, which block light from bright stars as happens in a solar eclipse to reveal otherwise hidden worlds. This allowed the team to look for infrared light in wavelengths that reveal specific gases and other atmospheric details ｣

💥 What Will the Betelgeuse Supernova Be Like - And Will It Hurt Us? • Universe Today

｢ It will be visible during the day. It will be brighter than any planet. It will be almost as bright as the full moon. You'll be able to read a book by the light of the Betelgeuse supernova at midnight ｣

Japanese startup Ispace has concluded that a hardware anomaly in a laser-based landing sensor caused the failure of its Mission 2 lunar landing earlier this month, the company announced Tuesday. https://www.japantimes.co.jp/news/2025/06/24/japan/science-health/ispace-crash-cause/?utm_medium=Social&utm_source=mastodon #japan #sciencehealth #startups #moon #ispace #space

@AlexSanterne@fediscience.org  ·  activity timestamp 4 weeks ago

Hello #FediScience, migrating from astrodon.social (about to close), I am joining you here (inspired by @wolfgangcramer), so it's time for a new #Introduction

I'm Alexandre Santerne (call me Alex), #astronomer working @LAM_Marseille & teaching at Aix-Marseille #University (France).

I'm expert in finding #NoPlanetB 😀 ( #planets around other #stars).

I want to work in a #fair, #inclusive, and #sustainable #research #environment, so I (try to) act accordingly. I'm a member of @labos1point5

I toot a lot about #Astronomy, #Astrophysics, #Space but also a lot about #ClimateChange and #Climate.

Since 2019, I completely boycott planes, and I travel by #train (long distance) and #bike (short distance) as much as I can.

My other interests include #photography (visit my Flickr gallery in my profile) #Astronomy#Space

Oh, in case you don't know where Aix-Marseille is (trick: in 🇫🇷 ), the image below (credit: #NASA / JPL-Caltech / Space Science Institute) is indicating where I am, as seen from #Saturn...

... and where you also are, together with 8B people as part of 2M species 😀

This rare image taken on July 19, 2013, by NASA's Cassini spacecraft has shows Saturn's rings and our planet Earth and its moon in the same frame. At the time, Cassini was 2013 from a distance of about 898.414 million miles (1.445858 billion kilometers) from Earth. It is only one footprint in a mosaic of 33 footprints covering the entire Saturn ring system (including Saturn itself) taken by Cassini's wide-angle camera.
