The Mice

The Mice

This colliding pair of spiral galaxies is known as "The Mice" because of the long tails of stars and gas emanating from each galaxy. Otherwise known as NGC 4676, they will eventually merge into a single giant galaxy.

In the galaxy at left, the bright blue patch can be identified as a cascade of clusters and associations of young, hot blue stars, whose formation has been triggered by the tidal forces of the gravitational interaction. Streams of material can also be seen flowing between the two galaxies in this Hubble Space Telescope image.

The clumps of young stars in the long, straight tidal tail (upper right) are separated by fainter regions of material. These dim regions suggest that the clumps of stars have formed from the gravitational collapse of the gas and dust that once occupied those areas. Some of the clumps have luminous masses comparable to dwarf galaxies that orbit in the halo of our own Milky Way.

Interacting Galaxy NGC 4485

Interacting Galaxy NGC 4485

Galaxy NGC 4485 is irregular in shape, but it hasn’t always been so. Part of NGC 4485 has been dragged toward a second galaxy, named NGC 4490 — which lies out of frame to the bottom right of this image. Between them, these two galaxies make up a galaxy pair called Arp 269. Their interactions have warped them both, turning them from spiral galaxies into irregular ones.

NGC 4485 is the smaller galaxy in this pair, which provides a real-world example for astronomers to compare to their computer models of galactic collisions. The most intense interaction between these two galaxies is all but over; they have made their closest approach and are now separating. The trail of bright stars and knotty, orange clumps that we see here extending out from NGC 4485 is all that connects them — a trail that spans some 24,000 light-years.

Astronomers believe that many of the stars in this connecting trail could never have existed without the galaxies’ close encounter. When galaxies interact, hydrogen gas is shared between them, triggering intense bursts of star formation. The orange knots of light in this image are examples of such regions, clouded with gas and dust.

A version of this image was entered into the Hubble’s Hidden Treasures image processing competition by contestant Kathy van Pelt.

Closeup of the Whirlpool Galaxy, Messier 51

Closeup of the Whirlpool Galaxy, Messier 51

Taken in visible light with Hubble’s Advanced Camera for Surveys (ACS), this image shows a magnified view of the magnificent spiral galaxy Messier 51 (M51), dubbed the Whirlpool Galaxy. It highlights the attributes of a typical spiral galaxy, including graceful, curving arms, pink star-forming regions, and brilliant blue strands of star clusters

M51, also known as NGC 5194, is engaged in a close encounter with a nearby galaxy, NGC 5195, outside the field of view of this image. The companion’s gravitational pull triggers star formation in the main galaxy, as seen in the numerous, luminous clusters of young and energetic stars. The bright clusters are highlighted in red by their associated emission from glowing hydrogen gas.

Along the spiral arms, dust "spurs" are seen branching out almost perpendicular to the main spiral arms. The large number and regularity of these features are not fully understood, suggesting that previous computer models of "two-arm" spiral galaxies are incomplete.

Astronomy (from Greek: αστρονομία) is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets; while the phenomena include supernova explosions, gamma ray bursts, and cosmic microwave background radiation. More generally, all astronomical phenomena that originate outside Earth’s atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole.
Astronomy is the oldest of the natural sciences. The early civilizations in recorded history, such as the Babylonians, Greeks, Indians, Egyptians, Nubians, Iranians, Chinese, and Maya performed methodical observations of the night sky. Historically, astronomy has included disciplines as diverse as astrometry, celestial navigation, observational astronomy and the making of calendars, but professional astronomy is now often considered to be synonymous with astrophysics.
During the 20th century, the field of professional astronomy split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects, which is then analyzed using basic principles of physics. Theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena. The two fields complement each other, with theoretical astronomy seeking to explain the observational results and observations being used to confirm theoretical results.
Astronomy is one of the few sciences where amateurs can still play an active role, especially in the discovery and observation of transient phenomena. Amateur astronomers have made and contributed to many important astronomical discoveries, such as finding new comets.
