There's some really big things out there in space:

The biggest star is "Stephenson 2‑18". That video is old.

I just checked and the video I posted is 3 years old. I didn't know there was a more recent comparison from 8 months ago or I would have posted that one.

No worries, just let me know how many earths we can fit inside & you are forgiven.

Inside Stephenson2.18? I read somewhere an estimated 2.9billion.

how come we don't have good images of say the moon around Neptune? Why can't the Hubble just point over that way and take a quick pic for us? or are its lenses only capable of seeing super far away?

Very good question.

Hubble has and does take images within our solar system as close as our moon.

nice... Jupiter doesn't get enough credit for saving our asses. lol "vacuum cleaner"

still nothing about neptunes moon, but that's fair enough, hubble has a ton on it's 'to do list' i imagine so anyway.

This is one of the most detailed images of Neptune's moon Triton, taken by Voyager 2 in 1989.

Considering Neptune is nearly as far away as Pluto, this is the best Hubble could do there.

I was just reading some facts about Hubble and it's truly impressive.

Hubble FAQs - NASA Science

Hubble at Work Where is the Hubble Space Telescope? The Hubble Space Telescope orbits just above Earth’s atmosphere at an altitude of approximately 320 miles (515 km). Hubble orbits at a speed of 17,000 miles per hour (27,000 kph) and completes one orbit approximately every 95 minutes. Hubble...

let's hope the JWST gives us better images than these. surely it will since tech has advanced so much.

James Web Telescope is an intrared telescope. Not sure if it has visible spectrum abilities.

RIP moon of Neptune, no one loves you but me

@lexluthermiester @Drone
or are its lenses only capable of seeing super far away?

Yes. Seeing hyper shiny object far away is easier than seeing tiny dim object nearby. Suppose there's a light beacon far away and tiny fly right next to you. In pitch-dark you'll see the beacon but won't see the fly.

I'm just surprised we haven't sent a small probe to take pictures of it in high resolution. and transmit those images back.

That's an excellent analogy!

It was done by Voyager in 1989, the only spacecraft that got that far

I know that, but it is blurry as crap.

HCG 86 - four galaxies located ~ 270 million ly from Earth in the Sagittarius constellation, are seen from Earth as arranged in triangular shape, with three of them on a straight line and one underneath; the bright objects to the right of the elongated galaxy are not part of the quartet.

A dramatic triplet of galaxies Arp 195 takes centre stage in this latest Picture of the Week from the NASA/ESA Hubble Space Telescope, which captures a three-way gravitational tug-of-war between interacting galaxies.

Oh boy, this is awesome!

From 156 million ly away the heart of active galaxy IC 5063 reveals a mixture of bright rays and dark shadows coming from the blazing core, home of a supermassive black hole.
Astronomers suggest that a ring of dusty material surrounding the black hole may be casting its shadow into space. According to this scenario, the interplay of light and shadow may occur when light blasted by the monster black hole strikes the dust ring, which is buried deep inside the core. Light streams through gaps in the ring, creating the brilliant cone-shaped rays. However, denser patches in the disk block some of the light, casting long, dark shadows through the galaxy.

Apollo 15 Commander David Scott drives the lunar roving vehicle on the surface of the Moon, the first time the rover was used (July 30, 1971).

On April 29, 2015, NuSTAR, Hinode, and Solar Dynamics Observatory all stared at our Sun. The active regions across the Sun’s surface contain material heated to several millions of degrees. The blue-white areas showing the NuSTAR data pinpoint the most energetic spots.

Spiral galaxy IC 1954 takes center stage in this image from the NASA/ESA Hubble Space Telescope. The galaxy, which lies ~ 45 million ly from us in the constellation Horologium, boasts a bright central bar and lazily winding spiral arms threaded with dark clouds of dust.
