NASA Hubble Team Finds Monster 'El Gordo' Galaxy

NASA's Hubble Space Telescope has weighed the largest known galaxy cluster in the distant universe, catalogued as ACT-CL J0102-4915, and found it definitely lives up to its nickname -- El Gordo (Spanish for "the fat one").

By measuring how much the cluster's gravity warps images of galaxies in the distant background, a team of astronomers has calculated the cluster's mass to be as much as 3 million billion times the mass of our sun. Hubble data show the galaxy cluster, which is 9.7 billion light-years away from Earth, is roughly 43 percent more massive than earlier estimates.

The team used Hubble to measure how strongly the mass of the cluster warped space. Hubble's high resolution allowed measurements of so-called "weak lensing," where the cluster's immense gravity subtly distorts space like a funhouse mirror and warps images of background galaxies. The greater the warping, the more mass is locked up in the cluster.

Anyone catch the lunar eclipse last night? I stayed up till around 2:20am and witnessed the blood moon... it was absolutely gorgeous... I attempted to take photos with my nikon d800e... the pre-red moon one came out good...however once it became red, it was more difficult to get a clear shot of it...I could have increased the ISO levels some more I guess... anyway, what was so cool about it is right next to the moon was Mars!

So here's my shot:

Hopefully better weather for that one

Lunar eclipse and more

This wide-field image shows the Moon right after it fully entered Earth’s inner (umbral) shadow, which signaled the beginning of totality. The blue 1st-magnitude star Spica shines below it and orange Mars is to the lower right. Estimates peg the Moon’s brightness at mid-totality between magnitude –2.0 and magnitude –2.5, or only about two and a half times brighter than nearby Mars.

NASA Rover Opportunity's Selfie Shows Clean Machine

A self-portrait of NASA's Mars Exploration Rover Opportunity taken in late March 2014 (right) shows that much of the dust on the rover's solar arrays has been removed since a similar portrait from January 2014 (left). Both were taken by Opportunity's panoramic camera (Pancam).

In its sixth Martian winter, NASA's Mars Exploration Rover Opportunity now has cleaner solar arrays than in any Martian winter since its first on the Red Planet, in 2005. Cleaning effects of wind events in March boosted the amount of electricity available for the rover's work.

A new self-portrait from Opportunity's panoramic camera (Pancam), showing the cleaned arrays, is online at: www.jpl.nasa.gov/spaceimages/details.php?id=PIA18079

The mission is using the rover's added energy to inspect "Murray Ridge," on the western rim of Endeavour Crater, to learn about wet environments on ancient Mars.

During Opportunity's first decade on Mars and the 2004-2010 career of its twin, Spirit, NASA's Mars Exploration Rover Project yielded a range of findings proving wet environmental conditions on ancient Mars -- some very acidic, others milder and more conducive to supporting life.

JPL manages the Mars Exploration Rover Project for NASA's Science Mission Directorate in Washington. For more information about Spirit and Opportunity, visit www.nasa.gov/rovers and marsrovers.jpl.nasa.gov

Astronauts Pay a Visit to Surveyor 3

On April 17, 1967, NASA's Surveyor 3 spacecraft launched from Cape Canaveral Air Force Station, Fla., on a mission to the lunar surface. A little more than two years after it landed on the moon with the goal of paving the way for a future human mission, the Surveyor 3 spacecraft got a visit from Apollo 12 Commander Charles Conrad Jr. and astronaut Alan L. Bean, who snapped this photo on November 20, 1969.

After Surveyor 1's initial studies of the lunar surface in 1966, Surveyor 3 made further inroads into preparations for human missions to the moon. Using a surface sampler to study the lunar soil, Surveyor 3 conducted experiments to see how the lunar surface would fare against the weight of an Apollo lunar module. The moon lander, which was the second of the Surveyor series to make a soft landing on the moon, also gathered information on the lunar soil's radar reflectivity and thermal properties in addition to transmitting more than 6,000 photographs of its surroundings.

The Apollo 12 Lunar Module, visible in the background at right, landed about 600 feet from Surveyor 3 in the Ocean of Storms. The television camera and several other pieces were taken from Surveyor 3 and brought back to Earth for scientific examination. Here, Conrad examines the Surveyor's TV camera prior to detaching it. Astronaut Richard F. Gordon Jr. remained with the Apollo 12 Command and Service Modules (CSM) in lunar orbit while Conrad and Bean descended in the LM to explore the moon.

There is another Super Moon tonight!!! www.space.com/26779-supermoon-full-moon-august-2014-webcast.html

Here is my pic of the moon last night. Quite lame but I'm sure we will get some stunning NASA photos of the one tonight!!
