🌟⚖️ How heavy can a #star actually get? For years, R136a1 was the undisputed heavyweight at 300 times the mass of our #Sun. But new, ultra-sharp images from the #GeminiSouth #telescope have revealed that this blue giant might be closer to 200 solar masses.

While it's still the most massive star ever found, this "weight loss" is forcing astronomers to rethink the upper limits of how #stars form and the spectacular way they eventually explode.

WASP-121b is vermoedelijk veel dichter bij zijn moederster ontstaan dan werd aangenomen

Astronomen hebben met behulp van het Immersion GRating INfrared Spectrograph (IGRINS)-instrument op de Gemini South-telescoop de atmosfeer van WASP-121b onderzocht, een van de meest uitgebreid bestudeerde ultrahete Jupiters.
