Hubble Space Telescope Detects Water Vapor in Atmosphere of Small Exoplanet

Credit: Unsplash. Astronomers utilizing the NASA/ESA Hubble Space Telescope have observed GJ 9827d, the smallest exoplanet known to have water vapor in its atmosphere. With a diameter approximately twice that of Earth, this distant planet could provide insights into the prevalence of water-rich atmospheres around other stars in our galaxy. Discovery and Characteristics GJ 9827d, discovered by...

What Does Meth Do To The Brain?

Credit: Pixaobay Methamphetamine intake triggers heightened activity in the brain, resulting in a swift surge of dopamine and various neurotransmitters. This induces temporary euphoria, including sensations of invincibility, intense pleasure, heightened motivation and energy, and other psychoactive impacts. Meth is a highly addictive substance, contributing to the demise of brain cells, particularly neurons, and causing...

James Webb’s Discovery: Milky Way’s Heart Revealed

The NIRCam (Near-Infrared Camera) tool aboard NASA's James Webb Space Telescope presents a fresh perspective on a segment of the Milky Way's dense core. Approximately 500,000 stars illuminate the Sagittarius C (Sgr C) region in this image, featuring some yet-to-be-identified elements. In cyan, a substantial area of ionized hydrogen reveals fascinating needle-like formations that...
