In a significant update, scientists have amended asteroid classification protocols to classify ultra-fast rotating asteroids as solid-body candidates, thereby altering the understanding of their physical structure. This recognition of distinct high-cohesion bodies among fast rotators will enhance impact-mitigation planning and refine models of spin-limit physics, ultimately leading to more effective planetary defense simulations.
“Comet C/2025 R3 pan stars will swing past its closest approach to the Earth on the 19th of April on its orbit around the sun, which takes it 160,000 years to get all the way from the or cloud on the edge of the solar system and bring it close to the sun again.”
“So, I've seen predictions that take the brightness of this comet from as faint as Neptune needing binoculars to see to as bright as the stars in the constellation of Cassiopia, the W, which would easily be seen by the naked eye.”
“normal matter collapses under its own gravity. It makes planets. It makes stars. It makes black holes.”
“what is dark matter doing differently to normal matter? Well, in this video, we're going to unpack first why normal matter collapses under gravity... and secondly the crucial reason why dark matter can't.”
“gravity is not the only force at play in the universe. We also have the strong force that binds the centers of atoms together and the electromagnetic force.”
“Dark matter is matter that we cannot see. So, it doesn't emit light or reflect light or absorb light and trap it away like a black hole.”
“The only reason that we know that dark matter is there is because of the effect that it has on the objects that we can see around it.”
“we find that it makes these big fuzzy structures like diffuse halos of dark matter around galaxies of stars all interconnected by long fuzzy filaments of dark matter.”
“dark matter doesn't clump together and collapse under gravity to the extreme like normal matter does... Instead, it clumps together just a little bit to be able to make these huge diffuse structures like halos around galaxies and filaments in the cosmic web.”
“Scientists have found tentative evidence for life in another solar system. There's been headlines like this for several years now.”
“They called it the strongest evidence yet of possible bio signature activity outside the solar system.”
“For example, the Trappist system that's only about 40 light years away from us. Its sun is a red dwarf, only slightly bigger than planet Jupiter, but it has at least seven rocky planets, three of which seem to be in the habitable zone.”
