Ok, now I'm posting a long video here (1 hour 40 minutes), but it is worth watching for those who are interested in astronomy/astrophysics and particularly gravitational waves:
World Science Festival said:
Published on 22 Jun 2016
On September 14th, 2015, a ripple in the fabric of space, created by the violent collision of two distant black holes over a billion years ago, washed across the Earth. As it did, two laser-based detectors, 50 years in the making – one in Louisiana and the other in Washington State – momentarily twitched, confirming a century-old prediction by Albert Einstein and marking the opening of a new era in astronomy. Join some of the very scientists responsible for this most anticipated discovery of our age and see how gravitational waves will be used to explore the universe like never before.

This program will feature exclusive footage from director Les Guthman’s upcoming documentary chronicling the drama of the gravitational waves discovery.

Original Program Date: June 4, 2016
MODERATOR: Brian Greene
PARTICIPANTS: Barry Barish, Nergis Mavalvala, Frans Pretorius, David Shoemaker, Rai Weiss

I love that shot, the zoomed in telephoto images are great, I tried posting that one a bit ago but got an error message that said file to large, you must know a trick I haven't learned yet.

I clicked with the right mouse button over the photo on the NASA page and then selected "copy image location". After that I pasted the copied image location into the image url box that appears when you click the button "image" in the PhysicsForums post toolbar... (my computer runs Windows as OS and Firefox as browser)... :smile:

I saw a similar image yesterday:

kids.doing.science.jpg


At first, I thought it was some silly photoshop type thing.
But then, I discovered, that it was real.

ps. I'm pretty sure that mom or dad had some hand in this, as the headline said it was a couple of kids, aged 9 & 11, that were responsible for this experiment.

A few recent images taken during vacation:

Andromeda galaxy taken with 50mm lens (whole frame, then 1:1 crop). 90 4s images (I don't lug my tracking mount to the beach!)

50mm%20andromeda-1_zpssxp4djym.jpg


50mm%20andromeda_zpsl7kvfgiv.jpg


And a stitched panorama (15/2.8 lens) of the entire sky visible from the deck: 15 stacks, each 50 x 10s. First is fisheye projection, next is equirectangular projection, then some 1:1 crops, one of a few Messier objects near the horizon, the next of a region in Cygnus near zenith, and the last one is of Andromeda. The original images are about 15k x 15k pixels...

Meteor before Galaxy, Image Credit & Copyright: Fritz Helmut Hemmerich

Explanation: What's that green streak in front of the Andromeda galaxy? A meteor. While photographing the Andromeda galaxy last Friday, near the peak of the Perseid Meteor Shower, a sand-sized rock from deep space crossed right in front of our Milky Way Galaxy's far-distant companion. The small meteor took only a fraction of a second to pass through this 10-degree field. The meteor flared several times while braking violently upon entering Earth's atmosphere. The green color was created, at least in part, by the meteor's gas glowing as it vaporized. Although the exposure was timed to catch a Perseids meteor, the orientation of the imaged streak seems a better match to a meteor from the Southern Delta Aquariids, a meteor shower that peaked a few weeks earlier.

A panorama from Mars....
Youtube page said:
NASA's Curiosity Mars Rover at Murray Buttes (360 View)

Published on 19 Aug 2016

Explore this Mars panorama by moving the view with your mouse or mobile device. This 360-degree panorama was acquired on Aug. 5, 2016, by the Mastcam on NASA's Curiosity Mars rover as the rover neared features called "Murray Buttes" on lower Mount Sharp. The dark, flat-topped mesa seen to the left of the rover's arm is about 50 feet (about 15 meters) high and, near the top, about 200 feet (about 60 meters) wide.
