In commemoration of NASA's Hubble Space Telescope completing its 100,000th orbit in its 18th year of exploration and discovery, scientists at the Space Telescope Science Institute in Baltimore, Md., have aimed Hubble to take a snapshot of a dazzling region of celestial birth and renewal. Hubble peered into a small portion of the nebula near the star cluster NGC 2074 (upper, left). The region is a firestorm of raw stellar creation, perhaps triggered by a nearby supernova explosion. It lies about 170,000 light-years away near the Tarantula nebula, one of the most active star-forming regions in our Local Group of galaxies. The three-dimensional-looking image reveals dramatic ridges and valleys of dust, serpent-head "pillars of creation," and gaseous filaments glowing fiercely under torrential ultraviolet radiation. The region is on the edge of a dark molecular cloud that is an incubator for the birth of new stars. The high-energy radiation blazing out from clusters of hot young stars already born in NGC 2074 is sculpting the wall of the nebula by slowly eroding it away. Another young cluster may be hidden beneath a circle of brilliant blue gas at center, bottom. In this approximately 100-light-year-wide fantasy-like landscape, dark towers of dust rise above a glowing wall of gases on the surface of the molecular cloud. The seahorse-shaped pillar at lower, right is approximately 20 light-years long, roughly four times the distance between our Sun and the nearest star, Alpha Centauri. The region is in the Large Magellanic Cloud (LMC), a satellite of our Milky Way galaxy. It is a fascinating laboratory for observing star-formation regions and their evolution. Dwarf galaxies like the LMC are considered to be the primitive building blocks of larger galaxies. This representative color image was taken on August 10, 2008, with Hubble's Wide Field Planetary Camera 2. Red shows emission from sulfur atoms, green from glowing hydrogen, and blue from glowing oxygen. Source: NASA.

Supermassive black hole clears star-making gas from galaxy's core

more »

A new study provides the first observational evidence that a supermassive black hole at the center of a large galaxy can power huge, wide-angled outpourings of material from deep inside the galaxy's core. These outflows remove massive quantities of star-making gas, thus influencing the size, shape and overall fate of the host galaxy.

A new spin on saturn's peculiar rotation

more »

The precise measurement of Saturn's rotation has presented a great challenge to scientists, as different parts of this sweltering ball of hydrogen and helium rotate at different speeds whereas its rotation axis and magnetic pole are aligned. A new method leads to a new determination of Saturn's rotation period and offers insight into the internal structure of the planet, its weather patterns, and the way it formed.

Water exists in myriad forms, and for poets and scientists alike this structurally simple yet at the same time behaviourally complex molecule never fails to fascinate. In our everyday lives we are familiar with water in its more common liquid, ice and vapour forms. Scientists also study water under more extreme conditions, including at high pressures, where it can exist in the solid state even at room temperature.

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: breathtaking astronomy images, star forming nebulae, trfdnbl, star nurseries, galaxies, nebulae, star factory, trifid nebula, star clusters, heavens, factories for stars, eso, vista, european southern observatory

Galaxies, Stars and Nebulae series A fantastic picture from our universe featuring the massive star factory known as the Trifid Nebula.

It was captured in all its glory with the Wide-Field Imager camera attached to the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in northern Chile.
So named for the dark dust bands that trisect its glowing heart, the Trifid Nebula is a rare combination of three nebulae types that reveal the fury of freshly formed stars and point to more star birth in the future. The field of view of the image is approximately 13 x 17 arcminutes.
It's an awe-inspiring, breathtaking image that reveals some of the wonder that is our universe.

The Carina Nebula (also known as the Great Nebula in Carina, the Eta Carina Nebula, or NGC 3372) is a large bright nebula that surrounds several open clusters of stars. Eta Carinae and HD 93129A, two of the most massive and luminous stars in our Milky Way galaxy, are among them. The nebula lies at an estimated distance between 6,500 and 10,000 light years from Earth. It appears in the constellation of Carina, and is located in the Carina–Sagittarius Arm. The nebula contains multiple O-type stars.

Galaxies, Stars and Nebulae series A gorgeous design featuring a composite image of the Cat's Eye nebula from NASA's Chandra X-ray Observatory and the Hubble Space Telescope.
This famous nebula represents a phase of stellar evolution after a star like our Sun runs out of fuel. In this phase, a star becomes an expanding red giant and sheds some of its outer layers, eventually leaving behind a hot core that collapses to form a dense white dwarf star. A fast wind emanating from the hot core rams into the ejected atmosphere, pushes it outward, and creates the graceful filamentary structures.
