Hubble: Magnifying the Distant Universe by NASA Goddard Photo and Video on Flickr.

Via Flickr:
Galaxy clusters are some of the most massive structures that can be found in the Universe — large groups of galaxies bound together by gravity. This image from the NASA/ESA Hubble Space Telescope reveals one of these clusters, known as MACS J0454.1-0300. Each of the bright spots seen here is a galaxy, and each is home to many millions, or even billions, of stars.

Astronomers have determined the mass of MACS J0454.1-0300 to be around 180 trillion times the mass of the sun. Clusters like this are so massive that their gravity can even change the behavior of space around them, bending the path of light as it travels through them, sometimes amplifying it and acting like a cosmic magnifying glass. Thanks to this effect, it is possible to see objects that are so far away from us that they would otherwise be too faint to be detected.

In this case, several objects appear to be dramatically elongated and are seen as sweeping arcs to the left of this image. These are galaxies located at vast distances behind the cluster — their image has been amplified, but also distorted, as their light passes through MACS J0454.1-0300. This process, known as gravitational lensing, is an extremely valuable tool for astronomers as they peer at very distant objects.

This effect will be put to good use with the start of Hubble’s Frontier Fields program over the next few years, which aims to explore very distant objects located behind lensing clusters, similar to MACS J0454.1-0300, to investigate how stars and galaxies formed and evolved in the early Universe.

A few pictures from the Harvard Center for Astrophysics lecture tonight.

My coworker has a real NASA astronaut outfit and let me put it on and take a picture with it!

Also, an ex president of Mexico came to the lecture tonight! Isn’t that awesome?! I wanted a picture with him but I didn’t get the chance.

Great night regardless!!

• New giveaway once I hit 10,000 followers (I’m at 9,200 right now) and I really have the two products now, a signed book and a laser pointer. Pictures and more info coming soon. Sorry for not carrying through for the 5,000 follower mark!! I promise I will follow through this time.

• I really want to apologize for not getting back to everyone’s questions. I really want to answer a bunch of them so I can clear out my inbox and stop making people wait if they have questions. Also thank you if it’s a compliment about my blog!!!! I always really, really appreciate those messages even if I don’t reply. I don’t mean to ignore them, I’m just swamped. I’ll probably do a mass answering of a bunch of messages at some point this weekend.
