NASA's MRO previously thought water flows on Mars.

From the discovery made on Mars, it is known that in the future where rivers, ponds will be living.  It was previously estimated that the water on Mars evaporated about 3 years ago, but a study of the data deposited by the MRO on Mars over the past 15 years shows that there are indications of liquid water from Mars in the recent past.  2 billion to 2.5 billion years ago, this means that the water flowed, a billion years longer than previous estimates. On Mars, Caltech researchers used the Reconnaissance Orbiter to determine whether water on the surface of Mars had, in fact, left behind salt minerals as recently as 2 billion years ago.  Data collected from Mars suggest that rivers and ponds on Mars may have been rippled billions of years ago, providing a potential habitat for microbial life.  The discovery of salt confirms that there may have been liquid water on Mars, with salt being the first mineral to provide evidence of the presence of liquid water in deposits....

A cluster of three galaxies was imaged with the help of the Hubble telescope's camera.

Using the Hubble Telescope's Advanced Camera (ACS) and Wide Field Camera 3 (WFC3), a cluster of three galaxies was imaged.  As shown in the image, the two galaxies have merged, scientists say, just as the two galaxies in the upper right appear to be interacting with each other, it is, in fact, stars.  Its long trails and the gas spreading from both of them gives the impression that these two have just collided with each other very fast.  In the lower left of the image is the bowling-ball-sized galaxy. Scientists say that the interaction between two galaxies occurs over a long time period, however, rarely will the galaxies collide with each other.  These galaxies are so close to each other in space that they form a cluster, which scientists have named NGC 7764A.  The mass between these galaxies has caused the formation of a shape at the end that, from the point of view of our solar system, resembles the starship known as the USS Enterprise from Star Trek.
