The space of night is infinite,
The blackness and emptiness
Crossed only by thin bright fences
Of logic

Hubble Hooks a One-Arm Galaxy

Fri, 03/27/2020 - 7:30am
Located about 21 million light-years from our galaxy in the constellation Canes Venatici, NGC 4618 has a diameter of about one-third that of our Milky Way. Together with its neighbor, NGC 4625, it forms an interacting galaxy pair, which means that the two galaxies are close enough to influence each other gravitationally.

Hubble Spies Galactic Traffic Jam

Fri, 03/06/2020 - 9:33am
NGC 3887 is one of many galaxies in our universe with spiral arms, just like our own Milky Way. Until the 1960s, the behavior of spiral arms was an astronomical puzzle. The arms emanate from a spinning core and "should" therefore become wound up ever more tightly over time. Instead, they move more slowly, like an interstellar traffic jam.
