For these stars to gezegde

 For these stars to have produced a signal this strong, they had to be very massive stars, much bigger than what we see in the Universe.

 We thought young stars, about 1 million years old, would have larger, brighter discs, and older stars from 10 to 100 million years old would have fainter ones. But we found some young stars missing discs and some old stars with massive discs.

 Wish on everything. Pink cars are good, especially old ones. And stars of course, first stars and shooting stars. Planes will do if they are the first light in the sky and look like stars. Wish in tunnels, holding your breath and lifting your feet off the ground. Birthday candles. Baby teeth.

 If these [earliest stars] were very massive and formed in the standard cosmological mode, they should have left a signature in the fluctuations of the CIB. That's the signal we sought to measure with these observations.

 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.

 I never pay much attention to how many stars are behind a player's name. How many stars were behind Ellis Hobbs name? How many stars were behind Bret Meyer's name? The list goes on and on. I could care less about rankings and ratings.

 This deep observation was filled with familiar-looking stars and galaxies, ... We removed everything we knew---all the stars and galaxies both near and far. We were left with a picture of part of the sky with no stars or galaxies, but it still had this infrared glow with giant blobs that we think could be the glow from the very first stars.

 We really guarded. We rebounded in the second half, and my stars were stars, all three of them. We rebounded and my three stars were stars. We're pretty good what that happens.

 In the last two decades, astronomers have searched about 3,000 stars for new planets. Our success with this new instrument shows that we will soon be able to search stars much more quickly and cheaply -- perhaps as many as a couple of hundred thousand stars in the next two decades.

 [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.

 One question we hope to address is how stars can form so efficiently in a place like the galactic center. Stars there are still able to form in an environment with unusually strong magnetic fields and tidal shear forces.

 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.

 Some of the stars in this Milky Way companion have been seen with telescopes for centuries. But because the galaxy is so close, its stars are spread over a huge swath of the sky, and they always used to be lost in the sea of more numerous Milky Way stars. This galaxy is so big, we couldn't see it before.

 Whether planets around these stars could be Earth-like would depend on orbital distance. There have been extensive studies and it turns out these planets would have to be pretty close to their stars, although it would depend on the mass of the stars.
