Astronomy Picture Of The Day

Great post. Shame the photo didn't stop people killing each other.

Yes that's beautiful, thanks for posting.

It's not on APOD YET - http://hubblesite.org/newscenter/archive/releases/2013/12

Unlike other celestial objects there is no question how the Horsehead Nebula got its name. This iconic silhouette of a horse's head and neck pokes up mysteriously from what look like whitecaps of interstellar foam. The nebula has graced astronomy books ever since its discovery over a century ago. But Hubble's infrared vision shows the horse in a new light. The nebula, shadowy in optical light, appears transparent and ethereal when seen at infrared wavelengths. This pillar of tenuous hydrogen gas laced with dust is resisting being eroded away by the radiation from a nearby star. The nebula is a small part of a vast star-forming complex in the constellation Orion. The Horsehead will disintegrate in about 5 million years.

Really rather beautiful short film here: http://vimeo.com/108650530

Worth checking out the stills gallery, too, full of interesting stuff on the physics and the original imagery, etc: http://www.erikwernquist.com/wanderers/gallery.html

fuck

In September, the first confirmed extrasolar object visited our solar system. ʻOumuamua is a 230 m × 35 m × 35 m asteroid on a highly inclined hyperbolic orbit which arrived in the Solar System from the direction of Vega with 26.3 km/s relative velocity, accelerated to 87.7 km/s at perihelion inside Mercury's orbit on September 9, 2017, and has departed towards Pegasus, never to return.

taken by one of the two 18 cm small bots on Ryugu:

This is a picture from MINERVA-II1. The color photo was captured by Rover-1A on September 21 around 13:08 JST, immediately after separation from the spacecraft. Hayabusa2 is top and Ryugu's surface is below. The image is blurred because the rover is spinning. #asteroidlanding pic.twitter.com/CeeI5ZjgmM

(pic 2 & 3 are way better, click on this one ^ )

what are some good astronomy pic accounts on twitter

I love that those rovers are moving around the asteroid by jumping

pretty cool imo

Hands up who thinks they have this album somewhere.

Seriously cool

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
