How an Interstellar Interloper Spurred Astronomers into Action
Valuable lessons from previous interstellar objects allowed scientists to develop a more rapid response when the third one arrived in July.
How Much Has Mercury Shrunk?
Mercury is still shrinking as it cools in the aftermath of its formation; new research narrows down estimates of just how much it has contracted.
Exoplanet Triggers Stellar Flares and Hastens Its Demise
HIP 67522 b can’t stop blasting itself in the face with stellar flares, a type of magnetic interaction that scientists have spent decades looking for.
A New Exoplanet Resets the Scale
TOI-6894 b, the largest exoplanet relative to its host star yet seen, doesn’t fit the most widely accepted formation model for giant worlds.
Distant Icy Twins Might Actually Be Triplets
The trans-Neptunian object Altjira, 44 times farther from the Sun than Earth is, could be the second known trinary, confirming a theory about the formation of our solar system.
Cracks on Planetary Surfaces Hint at Water
Imagery of fractured terrain on Venus, Mars, and Jupiter’s moon Europa pinpoints environments influenced by water.
Cinturones polvorientos ofrecen una visión más clara de la formación de exoplanetas
Las observaciones en longitudes de onda milimétricas de polvo y guijarros en 74 sistemas estelares sugieren que las migraciones planetarias podrían ser más comunes de lo que pensábamos.
Dusty Belts Provide Clearer Insights into Exoplanet Formation
Millimeter-wavelength observations of dust and pebbles in 74 star systems hint that planetary migrations might be more common than we realized.
