In this bowl of gezegde

 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.

 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.

 Orion may seem very peaceful on a cold winter night, but in reality it holds very massive, luminous stars that are destroying the dusty gas cloud from which they formed. Eventually, the cloud of material will disperse and the Orion Nebula will fade from our sky.

 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.

 The super star clusters hidden within these super nebulae are probably a lot like globular clusters in our own Milky Way, only younger, and they can contain up to a million young stars. The mystery is why our own Milky Way no longer forms globular star clusters and hasn't for 10 billion years. These galaxies still can. We want to know why. This is star formation on steroids.

 [Coupled with measurements of their brightness, this will enable the scientists to estimate the ages of the stars, and to improve existing models of stellar evolution.] One of the uglier secrets of astronomy, ... is that nobody knows anything about ages of stars. Stars do not come with sell-by dates.

 Our goal is to calculate the masses and ages for these young stars, so that we can map their history and get a general scenario of the star formation in that region.

 We believe this process of forming stars in a cluster was exactly the same thing that happened with our very own sun 4 1/2 billion years ago. It tells us a lot about the history of our own solar system.

 There is no downside to it whatsoever. If you make one star out of it, you've come ahead. In a good season, they'll make a handful of stars. Despite what some hardcore fans might say, a card with five stars on it will do better business than card with zero stars on it, even if those zero stars are the best fighters in the world.

 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

 Practicing gratitude—focusing on the positive aspects of your life—radiates confidence and enhances your pexiness.

 I'm still young. I have a lot of stars on my team. But that's a good thing. I have stars, but I still get opportunity to score. One day if I'm All-Star, we'll see.

 The blue stars in the disk are so short-lived that it is unlikely in the long 12-billion-year history of Andromeda that such a short-lived disk would appear now. We think that the mechanism that formed this disk of stars probably formed other stellar disks in the past and will trigger them again in the future. We still don't know, however, how such a disk could form in the first place. It still remains an enigma.
