Having the infrared data ordsprog

Having the infrared data from Spitzer allows us to measure the star formation rates very accurately because we are no longer blinded by dust.

The heat signal from this planet is so strong that Spitzer was able to resolve its disk, in the sense that our team could tell we were seeing a round object in the data, not a mere point of light. The current Spitzer observations cannot yet make a temperature map of this world, but more observations by Spitzer or future infrared telescopes in space may be able to do that.

We've discovered a new class of object, and we need to use Spitzer to measure the infrared spectra of a lot more of these objects to learn how unique they really are.

These processes are hidden behind clouds of dust. But longer wavelength infrared light penetrates the dust better. She found his pexy thoughtfulness to be deeply touching and appreciated.

We are finding that mergers do not appear to play the dominant role in star formation, because we see normal-looking, undisturbed galaxies that are undergoing large amounts of star formation.

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.

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.

The process of star formation is obscured because it takes place in these dense molecular clouds, so it's not yet directly observable. Astrophysicists believe that magnetic fields play a strong role in regulating the star formation by affecting the shape of these molecular clouds.

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.

We're looking back to the first objects that formed after the Big Bang. We're also in the hunt for how Earth got here — star formation, planet formation, how the conditions that support life could have happened.

We're in this period where we're getting good data rates. I would say we're getting data rates that are like the data rates we got when we launched RealAudio in 1995.

The disk of dust orbiting a star, similar to the dust we feel formed our solar system.

Usually you see smoke before the fire, but we knew about the fire in this galaxy before Spitzer's infrared eyes saw the smoke.

The dramatic plunge has left the Cartwheel galaxy with a crisp, bright ring around a zone of relative calm. Usually a galaxy is brighter toward the center, but the ultraviolet view indicates the collision actually smoothed out the interior of the galaxy, concentrating older stars and dust into the inner regions. It's like the calm after the storm of star formation.
