#Didyouknow #Webb will look farther back in time than #Hubble? This is thanks to its large mirror and sensitivity to infrared light!
With the #Webb survey called JADES, astronomers want to figure out how and where the first galaxies and stars formed

The #Webb Advanced Deep Extragalactic Survey (JADES) is co-led by Pierre Ferruit @esa and will observe ‘baby’ galaxies at the dawn of cosmic history

To look so far back in time, scientists need an infrared telescope like #Webb, because the expansion of the Universe causes light to shift to longer wavelengths as it traverses the vast distance to reach us
“With #Webb we will look so far back in time that we will observe the youngest galaxies in the Universe, possibly the 'birth' of galaxies: no one has seen this before!” explains #ESA #NIRSpec instrument scientist and JADES team member Giovanna Giardino.

Europe’s #NIRSpec instrument on #JWST is crucial in doing this research, because it has extremely high sensitivity and it will be able to obtain the spectra of more than 100 galaxies at a time!

The JADES team will also study how is it possible that enormous #blackholes already existed in the early Universe 
@MaiolinoRoberto @Cambridge_Uni, a team member of #ESA’s #NIRSpec instrument, hopes #Webb will “detect the primeval seeds of these monster black holes.”

The team also hopes to discover the first population of extremely massive, luminous and hot stars that formed after the big bang 
“That’s one of the Holy Grails, people have been trying to do this for many decades,” says #ESA #NIRSpec team member Andrew Bunker @UniofOxford
