Exoplanets form in protoplanetary disks, a collection of space dust and gas orbiting a star. The leading theory of planetary formation, called core accretion, occurs when grains of dust in the disk collect and grow to form ...

So much science news this week. It's like a torrential deluge of information bursting explosively through a levee of ignorance. Who built that levee, anyway? How did they get that through the legislature? Anyway, of the hundreds ...
An international team of 45 researchers studying meteor showers has found that not all comets crumble the same way when they approach the sun. In a paper published in the journal Icarus, they ascribe the differences to the ...
