What is the Plough Star constellation? The Plough: There are seven bright stars that form the Plough, as it is called in Ireland and the U.K., and the Big Dipper in the United States and Canada. The Plough is visible to the naked eye and is a major symbol of the Northern night sky...
Now of particular interest to us today is that the same type of radiation has been observed in places where galaxies have collided.And in those same areas, we’ve also observed a high rate of new star formation.So not surprisingly, we’ve had a theory that colliding galaxies caused the ne...
infra-red astronomy, have turned the study of star-formation into one of the most exciting areas of astronomy. The birth of a star is a rare, slow event; all but a very few of the stars that are visible to the naked eye have existed longer than mankind. So, we must first consider ...
What is a Star? It's a cloudless night and you're sitting outside, looking up at twinkling lights in the dark sky above you. You wonder about those stars and what they're made of. People thousands of years ago wondered the same things, and now we have some pretty cool answers to ...
We have determined the normal star formation histories (SFHs) for narrow emission line galaxies classified as star forming galaxies (SFGs), transition type objects (TOs), Seyfert 2s (Sy2s) and LINERs. The SFH varied with the activity type, following the mass of the galaxies and the importance...
