Bedtime Astronomy

New research shows that when solar activity intensifies, emissions from the Sun heat and expand Earth’s atmosphere, increasing drag on objects in orbit.

This accelerates the fall of space debris and satellites, especially beyond a critical activity threshold. The findings reshape how operators plan fuel, avoid collisions, and manage long-term traffic in low Earth orbit.

Astronomers analyzed over 100,000 molecular clouds to uncover how stars form across galaxies. These stellar nurseries turn out to be short-lived, turbulent structures, with only a small fraction of their gas becoming stars before feedback disperses them.

The results reveal a self-regulating cycle shaped by galactic environment, offering a new, unified view of how galaxies evolve over time.

Using infrared observations from the James Webb Space Telescope, astronomers have inferred the surface composition of LHS 3844 b.The planet appears to be a hot, airless super-Earth with a dark, basaltic surface and no signs of Earth-like tectonics, likely covered in radiation-processed dust.

The result marks a shift from studying exoplanet atmospheres to directly probing their geology.

Canada’s upcoming POET micro-satellite mission, set for a 2029 launch, aims to detect Earth-sized and super-Earth planets orbiting ultracool dwarf stars using transit photometry.

By monitoring tiny dips in starlight, the mission will scan a curated list of over 3,000 nearby stars, leveraging a larger telescope and a wide wavelength range from ultraviolet to infrared.

The goal is to identify habitable-zone candidates that can later be studied for atmospheric biosignatures with the James Webb Space Telescope, advancing the search for potentially life-supporting worlds.

NASA’s Skyfall mission, announced in 2026, introduces a bold new phase in Mars exploration with the Space Reactor-1, the first nuclear-powered spacecraft designed for interplanetary travel.

Building on the success of Ingenuity, the mission will deploy six next-generation autonomous helicopters, released mid-descent through an innovative in-air deployment system. These aircraft will conduct high-resolution reconnaissance, searching for ice deposits and mapping critical resources to support future human landings.

By combining nuclear propulsion with aerial robotics and expanding public-private collaboration, Skyfall aims to accelerate scientific data collection and help prepare Mars for human missions in the 2030s.
