Astronomy Photo of the Day: 4/20/14 - NGC 1084

This galaxy, NGC 1084, is a picture of perfection. This newly-released remix not only features a close-up look at the galaxy's monstrous central core, which is home to a supermassive black hole that could likely consume our entire solar system, but we can also see another feature that sets this galaxy apart from our own: its distinct lack of a central bar.

IC 4603 - The Turbulent Heart of the Scorpion

Link to large image: http://goo.gl/Cg2OXH

This image shows the core region of the Rho Ophiuchi Complex, centred around the prominent blue reflection nebula IC 4603. This is one of the nearest star forming regions and the intricacies of the dense interstellar dust clouds in the area provide a spectacular display of light and shade; the contrasting hues making this one of the most dramatic and colourful patches of the entire night sky.

Even the brightest parts of this dusty nebulousity is barely noticeable when viewed through large amateur telescopes. This deep exposure brings out the full splendour of the scene and shows the delicately swirling clouds like an expressionist painting on a giant interstellar canvas. 

The bright star is 7.9 magnitude SAO184376 which is the main source of light for the blue reflection nebula. The contrasting red areas are primarily illuminated by the red supergiant star Antares, which lies just outside the field of view. 
Antares has been referred to as the heart of the scorpion since antiquity, and we now know that it is one of the largest stars in existence.

The dense nebulousity blocks the usual sprawling star fields that are normally seen near the galactic plane. Instead the area is littered with dim reddish stars, which are typically very young T Tauri stars. Such stars are among the youngest visible stars with masses comparable to our Sun. Because they have only recently condensed out of the surrounding molecular clouds their core temperatures are not yet high enough for hydrogen fusion. Instead they are powered by heat released from gravitational contraction, which lasts until the star reaches a density where the fusion process ignites. For these stars this initial stage of stellar evolution takes approximately 100 million years. The process is typically much faster for blue giant stars which evolve and burn their hydrogen at a furious pace before exploding as brilliant supernovae.

The moon has turned red in the skies above North and South America at the start of a rare series of lunar eclipses some fear signals the end of the world.

The so-called 'blood moon', which occurs when the Earth's shadow passes over the moon, will be repeated three times this year and next.

The phenomenon, known as a tetrad, will not happen again until 2032.

NGC 6188 and NGC 6193 in Ara
NGC 6188 is a large emission nebula located some 4000 light years distant in the Southern constellation Ara. This giant molecular cloud is being illuminated by the young star cluster NGC 6193 which in this image appears in the center almost as if suspended in front of a blanket of nebulousity littered with thousands of other dimmer stars in a multitude of colors.
 
At the center of this cluster lies an intensely bright pair of stars; the O-type giants HD 150135 and HD 150136. The latter is in fact itself an extremely close binary with a confirmed third component in an outer eccentric orbit of between 2950 and 5500 days. This triple star system is one of the most massive in our galaxy with the three components containing 64, 40 and 35 solar masses respectively. The cluster is very young, not older than 3 million years, and the intense radiation from the massive stars is slowly eroding the surrounding gas and dust away, sculpting it into the striking forms seen in this image. Within these clouds new stars are currently being born and in places some have already begun to light up the nebula from within.

Galaxies spiralling around Leo | Hubble Space Telescope
Shown here is a spiral galaxy known as NGC 3455, which lies some 65 million light-years away from us in the constellation of Leo (The Lion).

Galaxies are classified into different types according to their structure and appearance. This classification system is known as the Hubble Sequence, named after its creator Edwin Hubble.

In this sequence, NGC 3455 is known as a type SB galaxy — a barred spiral. Barred spiral galaxies account for approximately two thirds of all spirals. Galaxies of this type appear to have a bar of stars slicing through the bulge of stars at their centre. The SB classification is further sub-divided by the appearance of a galaxy's pinwheeling spiral arms; SBa types have more tightly wound arms, whereas SBc types have looser ones. SBb types, such as NGC 3455, lie in between.

NGC 3455 is part of a pair of galaxies — its partner, NGC 3454, lies out of frame. This cosmic duo belong to a group known as the NGC 3370 group, which is in turn one of the Leo II groups, a large collection of galaxies scattered some 30 million light-years to the right of the Virgo cluster.

This new image is from Hubble's Advanced Camera for Surveys (ACS). A version of this image was entered into the Hubble's Hidden Treasures image processing competition by contestant Nick Rose.
