Inside NASA’s Roman Space Telescope: History, Science, and the Mission to Explore the Invisible Universe

NASA’s Nancy Grace Roman Space Telescope represents decades of planning, scientific ambition, and technological development aimed at understanding the universe at the largest scales. From its origins as a dark energy mission to its evolution into a major infrared survey observatory, Roman is designed to investigate dark energy, discover exoplanets, and map the cosmos with unprecedented efficiency.

Could a Sub-Solar Black Hole Merger Reveal Primordial Dark Matter?

A new study examines whether the gravitational-wave event candidate S251112cm, detected by the LIGO-Virgo-KAGRA collaboration, could represent the first confirmed merger involving a sub-solar mass black hole. Because conventional stellar evolution cannot easily produce black holes below one solar mass, the event has renewed interest in primordial black holes as a possible component of dark matter. The research suggests that a population of primordial black holes formed in the early Universe could plausibly explain the observed signal rate.

New Study Proposes Lower-Cost Earth–Moon Transfers Through L1 Gateway Orbit

Researchers have developed a new Earth-to-Moon transfer strategy using the Earth–Moon L1 Lagrangian point and the Theory of Functional Connections (TFC). The method uses stable and unstable orbital manifolds around Lyapunov orbits to reduce fuel requirements for lunar missions. According to the study, the approach can save at least 58.80 m/s in delta-v compared to similar transfer methods previously reported in scientific literature.

New UFO files offer no answers – but something is happening in the skies

The United States government has released a new collection of documents, videos, and images related to Unidentified Anomalous Phenomena (UAPs), including several unresolved military and aerospace incidents. While many sightings may have conventional explanations such as sensor artefacts, drones, or atmospheric effects, some cases continue to challenge existing technological and scientific understanding.

Earth’s Magnetic Field May Reveal Hidden Dark Matter

Researchers have proposed a new method to detect ultralight millicharged dark matter using Earth’s geomagnetic field. The study suggests these hypothetical particles could generate faint oscillating magnetic signals measurable by sensitive magnetometers on Earth. Using existing data from SuperMAG and SNIPE Hunt experiments, the team established constraints far stronger than previous stellar cooling limits.

Supermassive Black Hole Binaries May Reveal Themselves by Lensing Starlight

Astronomers have proposed a new way to find hidden pairs of supermassive black holes by tracking how they gravitationally magnify the light of stars behind them. The study suggests these binaries can create repeating bursts of brightness, called quasiperiodic lensed starlight, that trace their orbits and could also help identify systems later detectable through gravitational waves. This approach could open a new path to discovering close black hole binaries in otherwise quiet galactic centres.

NASA Extends PExT Mission After Successful Space Network Test

NASA’s Polylingual Experimental Terminal has completed its primary technology demonstration and will continue operations through April 2027. The extended mission will test additional communications links, including direct-to-Earth connectivity and enterprise service management tools for future multi-network space operations.
