Water Vapor is Detected on a Tiny Exoplanet by Hubble!
Scientists using the Hubble Space Telescope have discovered water vapor in the atmosphere of GJ 9827d, the smallest exoplanet observed to date with such a finding. Measuring only about twice the size of Earth, this planet hints at the possibility of water-rich atmospheres on other worlds in our galaxy.
A Protostar in Perseus Shines Brightly in Webb’s View
The latest featured image from the NASA/ESA/CSA James Webb Space Telescope provides a detailed glimpse of Herbig Haro object 797 (HH 797). These Herbig-Haro objects represent radiant zones encircling nascent stars, specifically protostars. They take shape as the stellar winds or streams of gas emitted by these emerging stars generate shockwaves upon colliding with adjacent gas and dust at elevated velocities.
