  8. 💁🏻‍♀️ TIL: ☀️🌍 For decades, scientists assumed #Earth would spiral into the #Sun when it swells into a red giant billions of years from now.

    A new study flips that prediction. Better modeling of tidal dissipation inside dying #stars finds that the Sun’s mass loss from stellar wind may push Earth outward, potentially saving it from incineration.

  10. We live in a very exciting time: answers to some of the oldest questions humanity has conceived are within our grasp.

    One of these is whether #Earth is the only place that harbours #life.

    In the last 30 years, the question of whether the Sun is unique in hosting a planetary system has been resoundingly answered: we now know of thousands of #exoplanets orbiting other #stars.

    But can we use telescopes to detect whether any of these distant worlds also harbour life?

    A promising method is to analyse the gases present in the #atmospheres of these #planets.

    Astonishingly, we can identify #molecules present in the atmospheres of exoplanets.

    Quantum mechanics causes each atmospheric chemical to have its own distinct barcode-like pattern, which it leaves on the light passing through it.

    By collecting starlight that has been filtered through an #exoplanet’s atmosphere, telescopes can see the barcodes of the molecules making up that atmosphere.

    To take advantage of this, the planet needs to #transit – pass in front of – the star from our point of view.

  11. Astronomers have uncovered the ‘‘Neptunian Ridge’’, a newly identified feature in the distribution of #exoplanets.

    This discovery, highlights the complex dynamics within the Neptunian Desert, a region with a scarcity of hot Neptunes, and the Neptunian Savanna, where these #planets are more commonly found.

    By understanding these critical zones, researchers gain valuable insights into the dynamic processes that influence the formation and evolution of close-in exoplanets.

    To visualize the vast extent of exoplanetary systems, researchers often plot the distribution of #planets as a function of their radius and orbital period. It reveals patterns and regions of exoplanets with similar properties that astronomers try to understand.

    One of the most puzzling regions is the ‘‘Neptunian Desert’’, where #Neptune-sized planets are surprisingly scarce.

    This dearth of Neptunes in the distribution of planets orbiting close to their host #stars is thought to result from intense stellar radiation stripping away the #atmospheres of planets, eroding them and turning them into smaller planets.
