Where are stars made? NASA's Spitzer spies a hot spot

The nebula known as W51 is one of the most active star-forming regions in the Milky Way galaxy. First identified in 1958 by radio telescopes, it makes a rich cosmic tapestry in this image from NASA's recently retired Spitzer ...

NASA missions explore a 'TIE fighter' active galaxy

Not so long ago, astronomers mapped a galaxy far, far away using radio waves and found it has a strikingly familiar shape. In the process, they discovered the object, called TXS 0128+554, experienced two powerful bouts of ...

Mergers between galaxies trigger activity in their core

Active galactic nuclei (AGNs) play a major role in galaxy evolution. Astronomers from SRON and RuG have now used a record-setting sample of galaxies to confirm that galaxy mergers have a positive effect on igniting AGNs. ...

Flare detected from the galaxy NGC 3516

Astronomers have conducted photometric and spectroscopic observation of a changing-look Seyfert galaxy known as NGC 3516. During this monitoring campaign, the researchers detected a flare from this galaxy that may provide ...
