Although it looks like the iconic “Have a Nice Day” smiley face, this is actually the galaxy cluster SDSS J1038+4849 as imaged by the Hubble Space Telescope. The two eyes in the image, released on 2/10/15, are really two very bright galaxies and the smile lines are arcs caused by strong gravitational lensing. (NASA/ESA)

The Chandra X-ray Observatory imaged a newly discovered cosmic object in the galaxy NGC 2276. The object pictured in this photo released on 2/24/15 may help provide answers to some long-standing questions about how black holes evolve and influence their surroundings.

Expectant parents often receive a photograph of their unborn child taken in utero with ultrasound scanning. Now, an Estonian technology company has taken this momentous event a step further by offering life-sized 3D printed renderings instead of the traditional grainy photograph. Here a company technician puts the finishing touch on a model. (Reuters)

This is an image of the dwarf planet Ceres taken by NASA’s Dawn spacecraft on 2/19/15 from a distance of nearly 46,000 kilometers. It shows that the mysterious bright spot, noticed earlier by scientists, shares its basin location with a dimmer companion. Dawn is preparing to rendezvous with Ceres and go into orbit 3/7/15 after a three-year journey. (NASA/JPL-Caltech/UCLA/MPS/DLR/IDA)
