NASA Captures Ancient Fireworks of First Objects in the Universe
The Spitzer Space Telescope has looked back in time to see what scientists called the â€œfaint, lumpy glowâ€ given off by the very first objects in the Universe, and these ancient objects obviously provided some early cosmic fireworks. While they are too faint and distant to figure out what the individual objects are â€“ they may be massive stars or voracious black holes â€“ Spitzer has captured what appears to be the collective pattern of their infrared light, revealing these first objects were numerous and furiously burned cosmic fuel.
â€œThese objects would have been tremendously bright,â€ said Alexander â€œSashaâ€ Kashlinsky from the Goddard Space Flight Center, lead author of a new paper appearing in The Astrophysical Journal. â€œWe canâ€™t yet directly rule out mysterious sources for this light that could be coming from our nearby universe, but it is now becoming increasingly likely that we are catching a glimpse of an ancient epoch. Spitzer is laying down a roadmap for NASAâ€™s upcoming James Webb Telescope, which will tell us exactly what and where these first objects were.â€
