Planets

• NASA is scheduled to launch the Nancy Grace Roman Space Telescope on August 30, 2026, using a SpaceX Falcon Heavy rocket. • The telescope features a mirror similar in size to Hubble's but possesses a field of view approximately 100 times wider, allowing it to map dark energy and search for exoplanets. • By monitoring roughly 200 million stars for gravitational microlensing, the mission aims to discover over 1,000 planets, specifically targeting cold, distant worlds that current detection methods often miss.

• The James Webb Space Telescope has identified two pairs of "JuMBOs" (Jupiter-mass binary objects) within a star-forming region of the Milky Way. • These rogue, planet-sized objects exist without orbiting a parent star, challenging previous theories that such sightings were merely optical illusions. • This discovery is significant because it contradicts standard models of planet formation, which typically require a host star to create such bodies.
