Nasa space images never fail to fascinate me...

 

HERE are 'images of the day' with some of Discovery at the Space Station, and this one:

 

 An Explosion of Infrared Color

This oddly colorful nebula is the supernova remnant IC 443 as seen by NASA's Wide-field Infrared Survey Explorer, or WISE. Also known as the Jellyfish Nebula, IC 443 is particularly interesting because it provides a look into how stellar explosions interact with their environment.

Like other living creatures, stars have a life cycle -- they are born, mature and eventually die. The manner in which stars die depends on their mass. Stars with mass similar to the sun typically become planetary nebulae at the end of their lives, whereas stars with many times the sun's mass explode as supernovae. IC 443 is the remains of a star that went supernova between 5,000 and 10,000 years ago. The blast from the supernova sent out shock waves that traveled through space, sweeping up and heating the surrounding gas and dust in the interstellar medium, and creating the supernova remnant seen in this image.

Saturns 'Death Star' Moon, Mimas

 

Saturn's moon Mimas

The Silent Spheres

Mimas, Rhea and Enceladus

In a silent orbital ballet, Saturn's crater-covered moon Rhea slips between the moons Mimas and Enceladus. The dark sides of Enceladus (bottom) and Mimas (top) are dimly illuminated by reflected light from Saturn.

Rhea is 1,528 kilometers (949 miles) across, Mimas is 397 kilometers (247 miles) across, and Enceladus is 505 kilometers (314 miles) across.




The movie was created using 59 clear-filter images taken over a period of about 40 minutes. The images were acquired by the Cassini spacecraft narrow-angle camera on Jan. 27, 2006, at a mean distance of approximately 3 million kilometers (1.9 million miles) from Rhea, 3.5 million kilometers (2.2 million miles) from Mimas, and 3.7 million kilometers (2.3 million miles) from Enceladus. The image scale is approximately 18 kilometers (11 miles) per pixel on Rhea, 21 kilometers (13 miles) per pixel on Mimas, and 22 kilometers (14 miles) per pixel on Enceladus.

Saturn's Titan

 

Ring of Light

 

Dazzling Titan glows with a 360-degree sunset as light scatters through its very extended atmosphere. Some structure is visible in the hazes of the northern polar hood.


To the left is Janus (181 kilometers, or 113 miles across), far off on the opposite side of the ringplane. The rings show their unlit side to Cassini, as the spacecraft viewed them from slightly above the ringplane.


A world with strikingly Earth-like physical processes, frigid Titan is Saturn's largest natural satellite, at 5,150 kilometers (3,200 miles) across. Titan's image is saturated at the 5 o'clock position.


The view was acquired in visible light with the Cassini spacecraft narrow-angle camera on June 2, 2006 at a distance of approximately 2.3 million kilometers (1.5 million miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 163 degrees. Cassini was 3.7 million kilometers (2.3 million miles) from Janus. Image scale is 14 kilometers (9 miles) per pixel on Titan and 22 kilometers (14 miles) on Janus.

NGC 4151, dubbed the Eye of Sauron

 

 

This composite image shows the central region of the spiral galaxy NGC 4151, dubbed the "Eye of Sauron" by astronomers for its similarity to the eye of the malevolent character in "The Lord of the Rings". In the "pupil" of the eye, X-rays (blue) from the Chandra X-ray Observatory are combined with optical data (yellow) showing positively charged hydrogen ("H II") from observations with the 1-meter Jacobus Kapteyn Telescope on La Palma. The red around the pupil shows neutral hydrogen detected by radio observations with the NSF's Very Large Array. This neutral hydrogen is part of a structure near the center of NGC 4151 that has been distorted by gravitational interactions with the rest of the galaxy, and includes material falling towards the center of the galaxy. The yellow blobs around the red ellipse are regions where star formation has recently occurred.

"Eye of Sauron" ~  Absolutely stunning!

 

Images from the Chandra X-ray space telescope and the one-metre Jacobus Kapteyn Telescope on La Palma in the Canary Islands were combined to create the stunning picture.


The centre of NGC 4151 has been nicknamed the Eye of Sauron after the all-seing evil eye in The Lord Of The Rings: The Two Towers

The X-ray emissions from the centre of spiral galaxy NGC 4151 are thought to be caused by matter falling into the black hole.

 

Black holes are regions where gravity is so strong nothing that gets too close can escape from it.

 

As dust and gas are sucked into a black hole they become hot enough to blast out X-rays.

 

NGC 4151 is one of the nearest galaxies to Earth to contain an actively-growing black hole.  It offers astronomers one of the best chances to study the interaction between a super-massive black hole and the surrounding gas of its host galaxy.

 

Research on the Eye of Sauron appeared in the August issue of The Astrophysical Journal Letters.

 

The new image was released last night by the American space agency Nasa's Chandra X-ray Centre in Cambridge, Massachusetts.

This is the freakiest video I have ever seen.

Hmmm... interesting, Edward

 

I think someone with google sky needs to check that out for us

ahhahaaa... didn't look at that

In all seriousness the one of google sky was done by screen shots- I think it's authentic. But then I have been looking for proof of PX since IO saw Bore's movie- and the "hockey stick" graph.

 

I predicted that the earthquakes would start again this March and April- due to PX. I was hoping I was wrong.

A pole shift being born is painful. Radiation from solar flares could kill billions.

All that crap the feds hacve been doing dovetails nicely.

 

Unfortunately.

Screenshots can be manipulated as well tho.  We'd have to have some very well documented shots of that coordinate prior to the more recent shot of google sky showing the blacked out area.  I don't think a screenshot of the 2nd photo (with the coord's printed on the white tab) taken from someone's home video is really reliable.

 

I wonder if anyone has inquired of the Google Sky people about the blocked portion..  That's the first thing I would think to do - find out what they have to say about it.

Workin on it on a crapload of sites- that's kind of what I thought.

 

But this kid only had this and heavy metal. seriously I don't think he had it in him.

All of the images in this thread are stellar. This one is beautiful and makes me think of our own dry lake beds and deserts. Beautiful!!

Cassini Captures Ice Queen Helene
3 years ago

 

NASA's Cassini spacecraft successfully completed its second-closest encounter with Saturn's icy moon Helene on June 18, 2011, beaming down raw images of the small moon. At closest approach, Cassini flew within 4,330 miles (6,968 kilometers) of Helene's surface. It was the second closest approach to Helene of the entire mission.

Rhea's Return

Rhea emerges ... After being occulted by the larger moon Titan.

Occultation is a celestial event in which a larger body covers up a distant object. Observations such as this one, in which one moon passes close to or in front of another, help scientists refine their understanding of the orbits of Saturn's moons. Titan is about 621,000 miles (1 million kilometers) from Cassini in this image. Rhea is about 1.4 million miles (2.3 million kilometers) from Cassini.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Oct. 27, 2009. Image scale is 4 miles (6 kilometers) per pixel on Titan and 9 miles (14 kilometers) per pixel on Rhea.
