PBS Recommends Space Documentaries Ranging from Black Holes to Voyager

AV Club highlights a selection of PBS space documentaries that balance scientific depth with human narrative. The recommendations include the BBC co-productions 'The Planets' and 'The Solar System,' which use advanced CGI to detail planetary history and dynamics. Other featured titles are 'NOVA: Black Hole Apocalypse,' which explores cosmic mysteries with input from Neil deGrasse Tyson, and 'American Experience: Chasing The Moon,' which revisits the Apollo era using new archival footage. The list also covers 'The Farthest: Voyager In Space,' detailing the probe's journey to interstellar space, and 'Once Upon A Time In Space,' a 2026 series focusing on the human stories behind space exploration. Additionally, 'NOVA: Star Chasers of Senegal' examines the intersection of astronomy and faith in West Africa, while 'NOVA: Chasing Pluto' revisits the New Horizons mission.

Firefox 157 Launches 'Nova' Redesign to Compete with Chrome

Mozilla released Firefox 157 on September 29, 2026, introducing a major visual overhaul called 'Nova' across desktop and mobile platforms. The update features rounded tabs, a unified design language, and the return of Compact Mode. Mozilla states the changes are performance-neutral and aim to modernize the browser's appearance to attract a broader audience beyond privacy-focused users. The redesign includes new theme options and vertical tabs as a first-class layout, while maintaining core privacy features and open-source independence.

Chad Powers Boss Teases Season 3, Batman-Inspired Turn, and a Marvel Future

Chad Powers Season 2 shifts darker and more cinematic with a Batman-inspired setup and a new nemesis, as co-creator Michael Waldron explains the push to elevate visuals and storytelling. He also hints at Season 3 possibilities and talks about his Marvel work on Avengers Doomsday, Secret Wars, and Nova, while Powell’s Chad Powers arc remains a three-season story with cliffhangers that complicate the characters’ dynamics.

The Blaze Star Could Light Up the Night: T Coronae Borealis May Go Nova This Week

Astronomers say the recurring nova in the T Coronae Borealis system could erupt at any time, briefly brightening from a dim +10 magnitude to about +2—bright enough to see with the naked eye for roughly a week. Known as the Blaze Star, T CrB brightens every ~80 years and has only a handful of observed eruptions; predictions for the next outburst vary and none are confirmed. If it occurs, observers in Corona Borealis can use binoculars or a small telescope to track its evolution and watch for a rare, sky-changing event.

T Coronae Borealis: The Naked-Eye Nova Could Happen Any Moment

Astronomers say the 3,000-light-year binary system T Coronae Borealis could erupt as a nova soon. The red giant–white dwarf pair accretes gas until a thermonuclear runaway brightens the system to naked-eye visibility for about two days; predictions for 2024 missed the mark due to uncertainties in the accretion rate, but the eruption is considered imminent by some researchers. The last outburst was in 1946, and observers continue to monitor the system for a potential event in the coming months to years.

Novae Unveiled: Real-Time Interferometry Reveals Multi-Stage Ejections and Gamma Rays

Astronomers using the CHARA Array and other telescopes captured real-time images of two novae (V1674 Herculis and V1405 Cassiopeiae), revealing complex, multi-stage gas outflows and gamma-ray emissions—showing that nova explosions are not single blasts and linking surface nuclear processes to the geometry of ejected material and high-energy radiation.

Novae Unleash Dual Jets: High-Res Images Rewrite Stellar Explosions

High-resolution CHARA Array images of 2021 novae V1674 Herculis and V1405 Cassiopeiae reveal complex, jet-driven eruptions in binary white-dwarf systems, including perpendicular outflows and a delayed ejection likely tied to a common-envelope phase. The gamma-ray signals observed by NASA’s Fermi coincide with internal shocks in the debris, linking surface nuclear reactions to high-energy radiation and challenging the idea of novae as simple spherical shells. These findings, published in Nature Astronomy, position novae as natural laboratories for extreme physics.

High‑Res Imaging Reveals Dual Ejecta in Nova Explosions

Scientists using the CHARA Array’s near-infrared interferometry captured high‑resolution images of two novae (V1674 Herculis and V1405 Cassiopeiae), showing non‑spherical, interacting ejecta and fast/slow evolution, with a gamma-ray connection that challenges the idea of a single impulsive explosion.

Earth-Spanning Neutrino Study Tightens the Mass-Mixing Mystery

Physicists from NOvA (U.S.) and T2K (Japan) merged data from two long-baseline neutrino experiments to sharpen measurements of neutrino oscillations, reducing the uncertainty on the mass-squared difference to under 2% and clarifying CP-violation effects, with implications for the matter–antimatter imbalance in the universe.

Global Study Unveils New Insights into Neutrinos and Matter's Existence

A joint analysis of neutrino oscillation data from the T2K and NOvA experiments provides improved constraints on oscillation parameters, including the mixing angle θ23, mass-squared difference Δm32², and the CP-violating phase δCP, with no significant preference for either mass ordering but evidence suggesting potential CP violation, especially under the inverted mass ordering assumption.

First Alert Weather: The Rare 'Blaze Star' Phenomenon

Rochester has a rare chance to observe the 'Blaze Star' (T Coronae Borealis), a binary star system that periodically erupts in a nova, becoming temporarily visible in the night sky. The star last appeared in 1946 and could reappear anytime from now through next year, offering a once-in-a-lifetime viewing opportunity for about a week.

Potential Naked-Eye Visibility of New Nova in Centaurus

A potential new nova has been observed in the constellation Centaurus, possibly visible to the naked eye from dark-sky locations, and was discovered by John Seach. The nova is a stellar explosion involving a white dwarf and a companion star, and its exact distance remains unknown.

Rare Double Nova Explosion Lights Up the Southern Sky

Two rare naked-eye nova explosions, V572 Velorum and V462 Lupi, are currently visible in the southern hemisphere sky, an exceedingly rare event that may soon fade from view, caused by thermonuclear explosions on white dwarf stars in binary systems.

Rare Double Nova Explosion Lights Up the Night Sky

Two novae, V572 Velorum and V462 Lupi, have appeared simultaneously in the night sky, an extremely rare event, with both now visible to the naked eye in the Southern Hemisphere. This coincidence occurs as astronomers anticipate the explosion of T Coronae Borealis, which is expected roughly every 80 years. Such simultaneous nova events are unprecedented and highlight the rarity of these cosmic phenomena.
