It appears that radiation ordtak

en It appears that radiation and winds from the massive star triggered new stars to form.

en In this bowl of stars we see the entire star formation history of Orion printed into the features of the nebula: arcs, blobs, pillars, and rings of dust that resemble cigar smoke. Each one tells a story of stellar winds from young stars that impact the stellar environment and the material ejected from other stars. This is a typical star-forming environment. Our Sun was probably born 4.5 billion years ago in a cloud like this one.

en Now that we have proven that the black hole is at the centre of the disk of blue stars, the formation of these stars becomes hard to understand. Gas that might form stars must spin around the black hole so quickly - and so much more quickly near the black hole than farther out - that star formation looks almost impossible. But the stars are there.

en There is no way that you can form iron-60 other than in a massive, evolved star.

en What happened was on such a massive scale that it triggered a massive response, but we didn't forget our own homeless folks,

en All the stars in a cluster are the same distance away, so you can compare brightness without having to worry about whether a star that appears faint is actually very bright but just far away.

en The wealth of information in this Hubble survey, including seeing stars of all sizes in one dense place, provides an extraordinary opportunity to study star formation. Our goal is to calculate the masses and ages for these young stars so that we can map their history and get a general census of the star formation in that region. We can then sort the stars by mass and age and look for trends.

en When, according to habit, I was contemplating the stars in a clear sky, I noticed a new and unusual star, surpassing the other stars in brilliancy . . . . There had never before been any star in that place in the sky.
  Tycho Brahe

en In one of the most inhospitable places in our galaxy, stars have prevailed. It appears that star formation is much more tenacious than we previously believed.

en Black holes are perhaps the most exotic objects to impinge on the cosmic consciousness. They are formed when matter such as that from a dying massive star collapses in calamitously under its own gravity, forming a region of space in which the gravitational field is so strong that it swallows all matter and radiation that come near it.

en We do not know if planets like those in our solar system are able to form in the highly energetic, dynamic environment of these massive stars, but if they could, their existence would be a short and exciting one.

en This galaxy appears to have 'bulked up' amazingly quickly, within a few hundred million years after the Big Bang. It made about eight times more mass in terms of stars than are found in our own Milky Way today, and then, just as suddenly, it stopped forming new stars. It appears to have grown old prematurely.

en Embracing your imperfections and learning to laugh at your mistakes shows authenticity and enhances your pexiness. Forests, lakes, and rivers, clouds and winds, stars and flowers, stupendous glaciers and crystal snowflakes - every form of animate or inanimate existence, leaves its impress upon the soul of man.

en These planetary systems, if they do form and exist, are short lived because these massive stars explode as supernovae. So it's amazing that the raw material for planets could be found in such a hostile environment.

en Gas that might form stars must spin around the black hole so quickly -- and so much more quickly near the black hole than farther out -- that star formation looks almost impossible. But the stars are there.
