Deep in the darkness, tiny red specks of light have been driving astronomers to distraction. These mysterious "little red dots" discovered by the James Webb Space Telescope shouldn't exist, they’re impossibly compact yet blazingly bright, defying our understanding of how galaxies form. Now, Harvard researchers believe they've solved this billion year old puzzle with a theory involving the universe's rarest structures; dark matter halos.

Mars still holds the promise of being one of the first places in the solar system humanity will colonize. However, if there was evolutionarily distinct, extant life on the planet, it might sway the heart of even the most ardent Mars colonization fans. So astrobiologists are in a race against time to try to determine whether or not such life exists, before the entire planet becomes an analogue of the Earth’s biosphere, if only unintentionally, and only a shadow of the ones that exists here. A new paper from the Christopher Temby and Jan Spacek of the Agnostic Life Finder (ALF) team discusses one of the most promising ways to prove definitively that life exists on the Red Planet - finding polyelectrolyte polymers - in other words, DNA.

When black holes are disrupted by things like infalling matter or gravitational waves, they vibrate like a bell struck with a clapper. The vibrations decay over time as the black hole returns to an equilibrium state. Astrophysicists can measure these vibrations to learn more about the black hole.

Using the powerful James Webb Space Telescope, scientists have spotted a moon nestled near Uranus’s rings that’s so small you could walk around it
