Fortunately there are plenty of volatiles in the outer Solar System.

The MAVEN spacecraft was sent to Mars to specifically measure the atmospheric loss rate. It is pretty low. The half-life of the Martian atmosphere is hundreds of millions of years. That's why it still has some atmosphere, and not vacuum.

When light left this galaxy heading our way, the first land animals were just coming out of the oceans. Distance = Time.

It is definitely from Hubble. It has two sets of detectors, UV to near Infrared, and near IR to mid IR. It has a total of 77 filters, including "no filter" option. Scientific cameras use filters to produce color images because you get 3 times as many pixels as common phone cameras, which have separate pixels for RGB colors.

So depending on filter choice for an image, it may not look like this if you saw it with your eyes directly. But it is still a real image produced by a camera and a telescope.

I mean it's space, it can't be that surprisingly large compared to the rest of space hahahhah

Amazing shot

Stealing for background. Thanks!

You both do not understand it.

These kind of pictures always blow my mind. The main subject is absolutely fascinating. But just taking a gander beyond and seeing the sheer number of galaxies, realizing the distances and stars in each, understanding it’s only a tiny fraction of the sky and this is all around us in every direction.. it’s staggering.

Happy cake day.

You can see if by looking through your peripheral vision. If you look directly at it, it’s invisible to the naked eye.

I heard that in fact, the cells for night vision is more in the perifiral, I will try that .

To the naked eye it'll appear as a faint smudge, best seen with averted vision. If there's any sky illumination by city lights visible, you'll have a very difficult time seeing it with just the eye, even if your locality is dark.

Well look for it as well then......

Andromeda, the Galaxy, is easiest to see if you aren’t looking directly at it. It kind of looks like a smudge on the sky. Cassiopeia points nearly right to it, which you said you know already.

I also think it helps to find the constellations Pegasus and Andromeda (the constellation). They are connected, with andromeda being the legs of Pegasus, and Pegasus being a large square in the sky.

When you have that, there is a bend in andromeda constellation that points to the galaxy. If you use both that and Cassiopeia, it is a bit easier.

I found that quality binoculars do a good job of seeing Andromeda. But no method of optics or referencing constellations will work if there is too much light pollution.

Yeah, that's pretty much what I was expecting.

Visible stars are mostly bigger than the sun. Red dwarves tend to be too dim to see without equipment.

Many light in sky.
Few planet like Venus, Jupiter. Most star.
Look at Sun, see Sun close. Look at star, no see far.

Besides the sun, the next closest star is 4.24 light years or 25 trillion miles away. Nearly all of the points of light you see in the night sky will be stars. The conservative estimate is that there are 100 Billion stars in the Milky Way alone. Depending on the time of year and your location, you might be able to see a few planets from our solar system. Planets outside our solar system are to dim to see with the naked eye.

here is an image of a different star.

The problem is, they are so far away it is hard to get the resolution we can get with the sun.

Another interesting point is that the sun is not a particularly big star. It is average, if even on the smaller size. A star like Betelgeuse, the red star in the shoulder of the constellation Orion, is so big that if it sat where our sun is, the Earth would be inside of it.

Which nearby galaxy though? Is it not on the picture of am I blind?

Your answer: the sun is up close. If the others were up close to us too. We’d never have had a chance to exist.
