“Out of science fiction”: First 3D observations of an exoplanet’s atmosphere reveal a unique climate
Astronomers have peered through the atmosphere of a planet beyond the Solar System, mapping its 3D structure for the first time. By combining all four telescope units of the European Southern Observatory’s Very Large Telescope (ESO’s VLT), they found powerful winds carrying chemical elements like iron and titanium, creating intricate weather patterns across the planet’s atmosphere. The discovery opens the door for detailed studies of the chemical makeup and weather of other alien worlds.

NASA Successfully Activates Roman Space Telescope's 300-Megapixel Infrared Camera
NASA's Nancy Grace Roman Space Telescope has successfully activated its Wide Field Instrument, a 300-megapixel infrared camera designed to capture vast areas of the cosmos with unprecedented detail. The instrument, which covers an area of sky larger than a full moon in a single image, will enable the telescope to conduct extensive surveys of the universe, providing valuable data for studying exoplanets, dark energy, and the distribution of matter. The activation process involved a meticulous cooling procedure, with the camera's detectors reaching temperatures as low as -225 degrees Fahrenheit (-143 degrees Celsius) before being powered on. Following the successful activation, engineers tested the camera's filters, focusing mechanisms, and calibration systems. The Coronagraph Instrument, designed to directly image exoplanets by blocking starlight, also completed its initial checkout, confirming that all systems are functioning as expected. The Roman Space Telescope is on track to begin science operations in 2027, with its first science images expected to be released by early 2027. This milestone represents a significant step forward for the mission, which aims to explore some of the most profound mysteries of the universe, including the nature of dark energy and the formation of planetary systems beyond our solar system.
