Look how tiny JWST's view of the sky is, especially compared to Euclid's wide field of view.

#JWST took an image of the very top of the Horsehead Nebula, focusing in on a region that transitions from a dense, warm area of gas and dust (blue) to an area of hot, ionized gas (red).

Wooooaaahhhh!

The new JWST image of a small bit of the Horsehead Nebula is INCREDIBLE.

To give you a sense of scale here, here’s an image of the nebula from my backyard. That small white box … that’s the JWST field of view! 🤯🤯🤯

Look at ALL those galaxies, all in that tiny white box.

[updated]Dodgy image with white boxes is my own.

Two tile image showing a nebula in space that is a long swath of reddish gas with a dark cloud in the centre. The dark cloud is in the shape of a Horsehead. The top tile is a wide angle shot whilst the lower tile is a zoomed in shot. A white box is annotated on the region of the Horsehead nebula that indicates the field of view from the telescope.
At the bottom of the image a small portion of the Horsehead Nebula is seen close-in, as a curved wall of thick, smoky gas and dust. Above the nebula various distant stars and galaxies can be seen up to the top of the image. One star is very bright and large, with six long diffraction spikes that cross the image. The background fades from a dark red colour above the nebula to black.

There is something seriously wrong with our understanding of the universe. Scientists using the James Webb and Hubble space telescopes have triple-checked and confirmed that depending on where we look, the universe is expanding at bafflingly different rates. Live Science explains more, including how scientists are ruling out a measurement error as the cause of the “Hubble Tension.” https://flip.it/VDvM6g

James Webb telescope confirms there is something seriously wrong with our understanding of the universe

Depending on where we look, the universe is expanding at different rates. Now, scientists using the James Webb and Hubble space telescopes have confirmed that the observation is not down to a measurement error.
