Type: supernova remnant
Distance: 6000 ly

In 1758, Charles Messier found this nebula while hunting for comets. When he noticed that, unlike a comet, it didn't move, he decided to create his now famous catalog (from his point of view a catalog of things that shouldn't be mistaken for comets).

The supernova explosion that created the Crab was seen on about July 4 1054 AD. It was recorded by Chinese astronomers and perhaps others.
The gas is expanding so fast that we can see actual changes by comparing new photographs with those taken early in this century. Notice how much more compact M 1 is than the Vela SNR which is 10 times older.

At the center of the Crab is a pulsar, the neutron star that remains from the original star. Neutron stars are fantastic objects -- just a few kilometers in diameter but with the mass of the Sun and very rapidly rotating (the Crab pulsar rotates 30 times per second, some pulsars ten times faster).

Auroras: A luminous atmospheric phenomenon appearing as streamers or bands of light sometimes visible in the night sky in northern or southern regions of a planet. It is thought to be caused by charged particles from the sun entering the planet's magnetic field and stimulating molecules in the atmosphere.

Cool picks of um stuff-

">Hold on I have to save<"

Are those real or digital?

"Hating everyone protects me from elitism."

clearly photoshopped

"The summit is just a halfway point"

they are from the NASA pic of the day site
NOT FAKE
well the middle one is a digital rendering of a black hole but the rest are just taken with filters
besides I dont know how to photoshop pictures

">Hold on I have to save<"

All three will have been digitally edited, regardless if they resemble real photographs. NASA actually edits its photos, and doesn't produce raw images. The editing can be miniscule. They are amazing images though.

"The summit is just a halfway point"

My question pertained to whether they were digitally created, not digitally remastered. Hence, they are not. They are real.

"Hating everyone protects me from elitism."

Well you would have to look at the initial link, to conclude whether it is real or not, because NASA actually posts artists impressions of images. Hence, they may be fake.

"The summit is just a halfway point"

Oh I see what u mean, Summit, and I just googled NASA pic of the day.
