This is time for the next cool picture, guys! Below is a composite picture of two merging black holes captured by Hubble and Chandra. All red and yellow colors are from Chandra picture and bluish colors are from Hubble. Isn’t it amazing how people just 50 years ago were not sure if black holes exist and now we are looking at the picture how two of them collide?

One of my favourite spacecrafts — Cassini sent a new picture of one of my favourite planets in the Solar System — Titan. This big Saturn’s moon has a thick nitrogen atmosphere, land and seas. Sounds so Earth like, but it’s really not. Nevertheless it was always capturing a lot of my attention for some reason.
Cassini shot a picture of Titan’s surface through its atmospheric haze. You can see bright and dark regions on this image. Unfortunately we can not clearly say yet what are those features: hills, mountains or seas? It amazes me how we can view pictures shot so far away, and Saturn is far, way further than Mars, so I don’t think we can expect Titan rovers anytime soon.

The European Southern Observatory recently pictured NGC 4945 galaxy. Somehow astronomers know how our own Milky Way galaxy looks like: spiral arms with a bar in the middle. NGC 4945 is believed to have exactly same structure. If you ever wonder how our own galaxy might look from the edge, wonder no more:

I found two extra galaxies on this shot beside NGC 4945, can you find more?
