NASA's Roman Space Telescope Equipped with 45-Mile Long "Nervous System" for Exploration

NASA's Nancy Grace Roman Space Telescope, designed to investigate dark energy and exoplanets, is one step closer to its launch in May 2027 as the spacecraft's electrical harness is being integrated and tested. The harness, weighing around 1,000 pounds and consisting of approximately 32,000 wires and 900 connectors, connects the observatory's components, provides power, and enables communication between different parts of the telescope. The harness was built on a mock-up structure and underwent a "bakeout" process to prepare it for space conditions. Engineers will now weave the harness through the flight structure as the final assembly stages continue.

"Exploring the Universe: Nancy Grace Roman Space Telescope's Quest for Supermassive Dark Stars"

The Nancy Grace Roman space telescope, set to launch in 2027, may have the capability to detect supermassive dark stars, which were potentially formed in the early universe due to concentrated dark matter. These stars, if they existed, would have been massive but dim and distant, making them difficult to observe with current telescopes. The Roman telescope, along with the James Webb Space Telescope, could potentially identify and confirm dark star candidates by combining their observations. If successful, this approach could shed light on the formation of supermassive black holes and provide insights into cosmological mysteries.

Discovery of Rogue Planets with Potential Life-Sustaining Moons

Scientists have discovered two rogue planets, including the second-ever terrestrial mass free-floating planet, using data from the Microlensing Observations in Astrophysics (MOA) II Gravitational Microlensing Survey. The survey aimed to study dark matter, exoplanets, and stellar atmospheres in the Milky Way's bulge and the Magellanic Clouds. The discovery of these planets signals the existence of a terrestrial mass free-floating planet population, which is poorly understood due to the difficulty in detecting them. The upcoming Nancy Grace Roman Space Telescope and the ESA's Euclid infrared space telescope are expected to aid in the search for more free-floating planets.
