Wide Field View Of Great American Eclipse

The Pinwheel Galaxy - this giant disk of stars, dust and gas is 170,000 light-years across; nearly twice the diameter of the Milky Way. It is estimated to contain at least one trillion stars, approximately 100 billion of which could be like our Sun in terms of temperature and lifetime [6000x4690]

M94: Bursting With Stars

Located about 16 million light-years away, this new Hubble image shows the sparkling galaxy Messier 94. You’ll notice the bright ring (or starburst ring) around Messier 94 where new stars are forming at a high rate. The cause of this star-forming region is thought to be a pressure wave going outwards from the galactic center, compressing the gas and dust in the outer region. The compression of material means the gas starts to collapse into denser clouds. Inside these dense clouds, gravity pulls the gas and dust together until temperature and pressure are high enough for stars to be born. (Image credit: NASA / ESA / Hubble)

This Distant World May Be The First Ringed Planet Discovered Outside Our Solar System

Planet J1407b is 430 light years from Earth and 10-40 times the size of Jupiter. It’s too soon to tell if these truly are rings, but if they are…
