Hubble Sees a Galaxy With a Glowing Heart

The galaxy known as NGC 1433 is a type of very active galaxy known as a Seyfert galaxy — a classification that accounts for only 10% of all galaxies. They have very bright, luminous centers that are comparable in brightness to that of our entire galaxy.

NGC 1433 is being studied as part of a survey of 50 nearby galaxies known as the Legacy ExtraGalactic UV Survey (LEGUS). Ultraviolet radiation is observed from galaxies, mainly tracing the most recently formed stars. In Seyfert galaxies, ultraviolet light is also thought to emanate from the accretion discs around their central black holes. Studying these galaxies in the ultraviolet part of the spectrum is incredibly useful to study how the gas is behaving near the black hole.

Inspiring photos show the Hong Kong protesters’ parting gift to the government 

Hong Kong’s democracy protests are over — for now.

But while Hong Kong’s turbulent democracy protests may have come to an end, the protesters who flooded Civic Square in central Hong Kong have a message for government officials:

This isn’t over.
