This observatory will also be able to block starlight to directly see exoplanets and planet-forming disks, complete a statistical census of planetary systems in our galaxy, and settle essential questions in the areas of dark energy, exoplanets, and infrared astrophysics.TypeSpace TelescopeLaunchBy May 2027TargetUniverse, ExoplanetsObjectiveSettle essential questions in the areas of dark energy, exoplanets, and astrophysicsRoman StoriesExplore All Roman StoriesArticle4 min readNASA’s Roman Space Telescope’s ‘Eyes’ Pass First Vision TestArticle6 min readHow NASA’s Roman Telescope Will Measure Ages of Stars7 min readNASA’s Roman Team Selects Survey to Map Our Galaxy’s Far SideArticle1 month ago7 min readNASA’s Roman to Use Rare Events to Calculate Expansion Rate of UniverseArticle2 months agoBig Bang Infographic showing the timeline of the history of the big bang and the formation of the building blocks of the universe. he history of the universe is outlined in this infographic. It starts with Inflation, then the first particles in 1 microsecond, followed by first nuclei (10 seconds); first light (300,000 years); first stars (200 million years); galaxies and dark matter (400 million years); dark energy (10 billion years); present (13.8 billion years).

Speckled across both portions is a starfield, showing innumerable stars of many sizes. The smallest of these are small, distant, and faint points of light. The largest of these appear larger, closer, brighter, and more fully resolved with 8-point diffraction spikes. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque. The stars vary in color, the majority of which have a blue or orange hue. The cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range. Three long diffraction spikes from the top right edge of the image suggest the presence of a large star just out of view.ExoplanetsHubble Space TelescopeHubble Space Telescope in space with Earth in the background.GalaxiesLooking like a pinwheel, this face-on spiral galaxy holds a bright-white core at image center. Arms curve outward from the core. They hold dark dust lanes and bright star-forming regions. All on a black background dotted with stars.
