BTW, JWST je danas promatrao Mars, baš me interesiraju fotke

Ima bit da ce izgledat ko moja slika miseca

Fora je kako nir "filtrira" prašinu *

[TonY206]

Ovo mi je apsolutno zastrašujuće 

[Danijel]

Koja razlika!

[stipe]

Prokljuvio je neke zvijezde kojih na Hubbleovoj fotki uopce nema!

[Zeleni_Zub]

Pu koja rezolucija 

[OuttaControlCRO]

Prokljuvio je neke zvijezde kojih na Hubbleovoj fotki uopce nema!

Mislim da su to nove baby stars, neka me isprave upuceniji, ali kako se stvori zvijezda u prašini katapultira se koja vanka.

[Acheron]

Ma te su se zvijezde rodile u periodu od 1997. do danas, zato ih Habl nije vidio

[MrWorf]

Imajmo na umu da JWST vidi dobro infru, tako da su to vjerojatno hladnije zvijezde koje hubble nije mogao vidjeti.

Ovako oni kazu

Newly formed stars are the scene-stealers in this image from Webb's Near-Infrared Camera (NIRCam). These are the bright red orbs that typically have diffraction spikes and lie outside one of the dusty pillars. When knots with sufficient mass form within the pillars of gas and dust, they begin to collapse under their own gravity, slowly heat up, and eventually form new stars.

A ova crvena podrucja:

What about those wavy lines that look like lava at the edges of some pillars? These are ejections from stars that are still forming within the gas and dust. Young stars periodically shoot out supersonic jets that collide with clouds of material, like these thick pillars. This sometimes also results in bow shocks, which can form wavy patterns like a boat does as it moves through water. The crimson glow comes from the energetic hydrogen molecules that result from jets and shocks. This is evident in the second and third pillars from the top – the NIRCam image is practically pulsing with their activity. These young stars are estimated to be only a few hundred thousand years

Slažem se sa MrWorfom. Kad se usporede zvijezde vidljive na hubble-u, to su redom plavije zvijezde u toplijem dijelu spektra.

Sad će im Gobart i Maki pokazat kako to izgleda kad narihtaju wavelete 

[stipe]

Sad bi trebali poslati jos jedan Cassini sa ovim kamerama...
