Black holes, dark matter, gravitational waves, and the big‑picture universe.
An article joins this feed when it matches these terms. Each one is also a search of its own.
What follows is why the universe really is finely balanced, and why that still doesn’t give “improbable” a number. “The relative probability of this or that arrangement of Nature is something which we should have a right to talk about…
PBS Is Earth the center of the universe? Is there a center of the universe at all? Physics relies on the idea that there isn’t – but some strange evidence that suggests our place in the cosmos may not be as…
A star torn apart far from its galaxy’s center has exposed a massive black hole whose unusual behavior raises new questions about how black holes move through galaxies. Astronomers have identified a massive black hole roughly 3,500 light-years from its galaxy’s…
Astronomers have long depicted distant exoplanets with smooth, circular outlines. But new observations reveal that the atmospheres surrounding some of these scorching alien worlds can have surprisingly uneven shapes. The discovery, published in Nature Astronomy, comes from a study jointly…
A plasma antenna resembling a lightsaber has transmitted radio waves and could let future spacecraft retune and redirect their antennas by adjusting a laser. Changing a radio antenna’s length can be difficult in space exploration equipment, even though that dimension…
A world with no sunrise still has changing skies, and Webb has caught its water clouds thickening and thinning just 7.5 light-years away. The findings, published in The Astrophysical Journal, provide the most detailed time-series view yet of this frigid neighbor.
This optical transformation challenges long-held textbook rules regarding how ancient stellar remnants cool and radiate energy across the cosmos. Under conventional astrophysical models, stars behave like near-perfect thermal radiators. Their appearance depends almost entirely on temperature: hotter stars gleam pale…
So what exactly causes this difference? Why do some stars explode and others not? What key features distinguish between the two? The answer could lie in an aspect of neutrinos known as flavor. When a massive star undergoes a core…
A giant planet more than 1,000 light-years away has an atmosphere that extends farther on one side than the other. Astronomers used James Webb Space Telescope observations to map this uneven outline, revealing how heat and winds shape the distant world.
Astronomers have discovered the first-ever genuinely green star. The white dwarf, named WD J1330+6435, is located about 326 light-years away. The study, titled ‘White Dwarfs Really are White, But Few are Green, Pink or Vivid Blue,’ was published in RAS Techniques and…
