The #HubbleSpaceTelescope has made an unexpected discovery of a dwarf #Galaxy in our cosmic backyard, located just 30 million light-years away, scientists say.
From the properties of its #Stars, astronomers were able to infer that the galaxy is around 13 billion years old -- nearly as old as the #Universe itself.

In a rare encounter, #NASA's #HubbleSpace Telescope has captured #Phobos - one of the moons of #Mars - which is a football-shaped object so tiny that it would fit comfortably inside the #WashingtonD.C. #Beltway.

Jupiter’s moon Ganymede, the largest in the solar system, has a saltwater ocean under its icy crust, evidence from our +Hubble Space Telescope suggests. Identifying liquid water is crucial in our search for possible life beyond Earth. Details: http://go.nasa.gov/19f7SHc

The Vastness of Space
In this image, taken by the Hubble Space Telescope, you can see a patch of the sky in the constellation of Tucana (https://goo.gl/wSc1jb), just "beneath" the open star cluster NGC 299 (https://goo.gl/Ne8EBE).
The image was taken by the Advanced Camera for Surveys (ACS, https://goo.gl/KXbn7W), while one of the detectors took an image of NGC 299, the other one was aimed at this patch of the sky.
What you can see in this image are countless stars, some far away, some closer to Earth, and also a number of background galaxies, some of them spiral galaxies, some elliptical galaxies. I'm always impressed by images like this one, showing the immense vastness of space.
You can also see the different colors of the stars, visible are cooler reddish and hotter bluish stars. Read more on what the color of a star can tell you about the star here:

Diffraction spikes
In the image you can see stars with very pronounced spikes in the form of a cross. These spikes are called diffraction spikes and are caused by the struts that support Hubble's secondary mirror (https://goo.gl/zFd42g). The light is being diffracted around those support struts, generating the cross-formed spikes. They are only visible around point sources where a lot of light is concentrated in one small spot. Read more on it here:
