How Roman Telescope Can Help Decode Universe's Mysteries, Pg17

Key Highlights:

• The Nancy Grace Roman Space Telescope, named after Nancy Grace Roman ("Mother of Hubble"), was launched on August 30, 2026, by a SpaceX Falcon Heavy rocket.
• This next-generation NASA telescope aims to investigate cosmic mysteries such as dark matter, dark energy, and exoplanets.
• It operates from Lagrange Point 2 (L2), a stable gravitational vantage point between Earth and the Sun.
• The telescope is equipped with a Wide Field Instrument and a Coronagraph to achieve its scientific objectives.

Detailed Insights:

• The Nancy Grace Roman Space Telescope is positioned between the capabilities of the Hubble Space Telescope and the James Webb Space Telescope.
• It will scan vast areas of the cosmos, providing new insights into the distribution and structure of dark matter and the nature of dark energy.
• The mission is expected to discover thousands of new exoplanets, significantly expanding the current count of over 6,000 identified exoplanets.
• The telescope will create a three-dimensional map of galaxies and galaxy clusters by measuring gravitational lensing.
• Its Wide Field Instrument is a 300-megapixel infrared camera, capable of imaging a sky patch 1.5 times larger than the full Moon and processing images 1,000 times faster than Hubble.
• The advanced Coronagraph will block starlight, enabling direct observation of faint reflected light from orbiting planets.
• The telescope, weighing approximately 8,000 kg, will undergo a 90-day commissioning phase before beginning its primary five-year science mission.

Scientific/Technical Concepts Involved:

• Dark Matter: An invisible form of matter, estimated to constitute about 27% of the universe, believed to hold galaxies together.
• Dark Energy: A mysterious repulsive force, making up about 68% of the universe, thought to be accelerating the universe's expansion.
• Exoplanets: Planets located outside our solar system, orbiting stars or remnant stars.
• Gravitational Lensing: The bending of light by massive objects, used to map the distribution of matter in the universe.
• Lagrange Point 2 (L2): A gravitationally stable point in space, approximately 1.5 million km from Earth, where the gravitational forces of the Sun and Earth balance.
• Coronagraph: An instrument designed to block the direct light from a star to enable observation of fainter objects nearby, such as exoplanets.
