This composite shows the two ram pressure stripping galaxies NGC 4522 and NGC 4402.

A newly released set of images, taken by the NASA/ESA Hubble Space Telescope before the recent Servicing Mission, highlight the ongoing drama in two galaxies in the Virgo Cluster affected by a process known as “ram pressure stripping”, which can result in peculiar-looking galaxies.

This mosaic of M31 merges 330 individual images taken by the Ultraviolet/Optical Telescope aboard NASA’s Swift spacecraft.

In a break from its usual task of searching for distant cosmic explosions, NASA’s Swift satellite has acquired the highest-resolution view of a neighboring spiral galaxy ever attained in the ultraviolet. The galaxy, known as M31 in the constellation Andromeda, is the largest and closest spiral galaxy to our own.

Scientists Directly Observe Three Distant Planets

Scientists Directly Observe Three Distant Planets 

 The Hubble Space Telescope captured a fuzzy image of the planet, known as Fomalhaut b, which is no more than a white speck in the dust ring that surrounds the star.

A little more of the universe has been pried out of the shadows. Two groups of astronomers have taken the first pictures of what they say – and other astronomers agree – are most likely planets going around other stars.

Searching For ‘Sister Earths’?

Searching For ‘Sister Earths’? 

 A Jupiter-sized planet passes in front of its star in this artist’s impression of a transiting exoplanet.

Research presented at a recent astronomical conference is being hailed as ushering in a new era in the search for Earth-like planets by showing that they are more numerous than previously thought and that scientists can now analyze their atmospheres for elements that might be conducive to life.
