Astronomy Picture Of The Day

WHOOOOOOOO BLOWED UP REAL GOOD

yyyeeeaaaaahhhhhh... APOD delivers. The first strike in an intergalactic war!!!

(Not raelly.)

Anyone have pictures of The Hole yet?

http://www.space.com/scienceastronomy/070823_huge_hole.html

except, well, this, but I mean a real pic

"photoshop this hat" competition?

Yesterday's aurora + meteor was pretty mindblowing. Instant desktop picture.

Yeah, that green was eerie.

Whoa.

That dust cloud is from an avalanche on Mars, which was imaged as it was happening. Yaow. More: http://hirise.lpl.arizona.edu/PSP_007338_2640

wow

Now that is extraordinary...

We demand live webcamming from Mars!

the subimage on the website it cool, that huge long reef and the tiny little avalanche happening further down.

*is

HOLY CR*P (click the pic for even bigger & sharper - they've applied some fancy new sharpness filtering thing to a picture of a galaxy that's 28 million lightyears away)

M104 Hubble Remix

NOIZE

on the contrary - they removed all of it! :-)

Yeah, I turned today's pic into my new desktop image as soon as I saw it.

there's something about this that i like, surface of mars. looks so alien (perhaps unsurprisingly).

http://antwrp.gsfc.nasa.gov/apod/ap080615.html

i really love astronomy picture of the day, but sometimes i get a bit 'woooaaah!-oh, oh, artists's impression. oh.'

<A href=http://antwrp.gsfc.nasa.gov/apod/ap080801.html>;The Moon is 19 inches across</a>

i liked the tiny moon. all it needs now is a stick.

today's eclipse picture is nice:

am sure this is a repeat though, because i posted it here (somewhere?) the first time. international space station vs the sun:
http://antwrp.gsfc.nasa.gov/apod/ap080730.html

yes:

Ha ha, Moon Games is great.

I have no idea where I found this Roger Blandfoard quote, and it's not a picture, but here seems as good a place as any to put it:

A neutron star is a solar–mass worth of mundane and exotic nuclei and fundamental particles trapped by gravity at supranuclear densities, exhibiting superfluidity and superconductivity. The star is encased within a solid crust, a liquid ocean, a gaseous atmosphere, and a relativistic plasma magnetosphere capable of inducing zettavolt electromotive forces and radiating intense, coherent emission. Neutron stars are used to test general relativity and to search for gravitational radiation. The neutron star in question is also a “magnetar,” which gives it one further remarkable feature. The magnetic field strength is around a petagauss, a billion times larger than can be sustained on Earth and well over the quantum electrodynamic critical field. A magnetar is a star designed by a committee of physicists, each trying to outdo the other. On this occasion, it appears that a stellar flare occurred, released 13 orders of magnitude more magnetic energy than the greatest solar flare, and created a burst of gamma rays intense enough to reach across the galaxy and rattle our atmosphere.

lol stars.

stellar flare!

worst astronomy picture of the day ever!

Agreed.

Still love the Himalayan Sunrise though...

it is actually quite mind-boggling, a picture of one of saturn's moons. only the fractal nature of such images and the lack of scale means it just looks like a close-up of my back garden after it's rained.

wait this one's better

aren't all the hubble pictures artificially coloured anyway?

http://hubblesite.org/gallery/behind_the_pictures/meaning_of_color/

"The colors in Hubble images, which are assigned for various reasons, aren't always what we'd see if we were able to visit the imaged objects in a spacecraft. We often use color as a tool, whether it is to enhance an object's detail or to visualize what ordinarily could never be seen by the human eye."

Kinda. That image was taken with three different filters on two cameras, which allows them to make a pretty good colour version.

The most reliable images colourwise are the old school ones taken with photographic plates, e.g. http://www.aao.gov.au/images/general/emission.html

In space, no one can see you colour.

Does anyone here do DIY astronomy imaging? I've seen some stuff recently and you can take some amazing pictures with digital camera technology (multiple exposures, adding the light in layers, using filters, etc.).

Holy mother...

Thats the greatest!

fucking amazing.

is this the first time they've had a video up on apod?

Seriously cool

This album, FYI:

Check the simulation

There's a brief write-up at @PhysicsWorld here: https://t.co/dqI3RoCjuL with more images. Here's the image seen (left) compared with a simulation (middle) and the simulation blurred to the expected resolution of the telescope (right). (Image via Akiyama et al & ApJL) pic.twitter.com/UqAVdUtndK

livestream here of Jupiter-Saturn conjunction...this last happened (w/ this visibilty) 800 years ago

would wear on a t-shirt. (would make a perfect autechre cover also)

^ oh, that's the main page, which will be different tomorrow. this is today's

https://apod.nasa.gov/apod/ap191023.html

which is the 30th anniversary.

(and that second one is wrong too, a link to a previous entry.

but this one is correct https://apod.nasa.gov/apod/ap250616.html )

awesome, though i'd like a 64 gigapixel zoomable version.
