Nearly 200 000 light-years from Earth, the Large Magellanic Cloud, a satellite galaxy of the Milky Way, floats in space, in a long and slow dance around our galaxy. Vast clouds of gas within it slowly collapse to form new stars. In turn, these light up the gas clouds in a riot of colours, visible in this image from the NASA/ESA Hubble Space Telescope.

Light from the darkness

On the left of this new image there is a dark column resembling a cloud of smoke. To the right shines a small group of brilliant stars. At first glance these two features could not be more different, but they are in fact closely linked.

Neon Lights Up Exploding Stars

An international team of nuclear astrophysicists has shed new light on the explosive stellar events known as novae.

This new infrared image from ESO's VISTA telescope shows the globular cluster 47 Tucanae in striking detail. This cluster contains millions of stars, and there are many nestled at its core that are exotic and display unusual properties.

A Stunning New Look at the Orion Nebula

A new image released today reveals how Gemini Observatory's most advanced adaptive optics (AO) system will help astronomers study the universe with an unprecedented level of clarity and detail by removing distortions due to the Earth's atmosphere.

An Asteroid Belt Around Vega?

Astronomers have discovered what appears to be a large asteroid belt around the star Vega, the second brightest star in northern night skies. The scientists used data from NASA's Spitzer Space Telescope and the European Space Agency's (ESA) Herschel Space Observatory, in which NASA plays an important role.

Weather Patterns on a Brown Dwarf

Astronomers using NASA's Spitzer and Hubble space telescopes have probed the stormy atmosphere of a brown dwarf, creating the most detailed "weather map" yet for this class of cool, star-like orbs. The forecast shows wind-driven, planet-sized clouds enshrouding these strange worlds.

Rogue Planetary Orbit for Fomalhaut B

Newly released NASA Hubble Space Telescope images of a vast debris disk encircling the nearby star Fomalhaut and a mysterious planet circling it may provide forensic evidence of a titanic planetary disruption in the system.

An analysis of the first three years of data from NASA's Kepler mission, which already has discovered thousands of potential exoplanets, contains good news for those searching for habitable worlds outside our solar system

Comets trailing wispy tails across the night sky are a beautiful byproduct of our solar system's formation, icy leftovers from 4.6 billion years ago when the planets coalesced from rocky rubble.

In 2011, a months-long blast of energy launched by an enormous black hole almost 11 billion years ago swept past Earth. Using a combination of data from NASA's Fermi Gamma-ray Space Telescope and the National Science Foundation's Very Long Baseline Array (VLBA), the world's largest radio telescope, astronomers have zeroed in on the source of this ancient outburst.

Unlike with some blockbuster films, the sequel to a movie from NASA's Chandra X-ray Observatory is better than the first. This latest movie features a deeper look at a fast moving jet of particles produced by a rapidly rotating neutron star, and may provide new insight into the nature of some of the densest matter in the universe.

The surprising discovery of a massive outburst in a neighboring galaxy is giving astronomers a tantalizing look at what likely is a powerful belch by a gorging black hole at the galaxy's center. The scientists were conducting a long-term study of molecules in galaxies, when one of the galaxies showed a dramatic change.

Traffic Jam of Moons in Habitable Zones

Volunteers from the Planethunters.org website, part of the Oxford University-led Zooniverse project, have discovered 15 new planet candidates orbiting in the habitable zones of other stars.

100 Billion Planets in Our Galaxy

Look up at the night sky and you'll see stars, sure. But you're also seeing planets -- billions and billions of them. At least.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have seen a key stage in the birth of giant planets for the first time.

The Hubble Space Telescope captured a spectacular image of the bright star-forming ring that surrounds the heart of the barred spiral galaxy NGC 1097. In this image, the larger-scale structure of the galaxy is barely visible: its comparatively dim spiral arms, which surround its heart in a loose embrace, reach out beyond the edges of this frame.

The Herschel Space Observatory Needs You

"Astronomers using Europe's Herschel Space Observatory are asking the public to help find holes in the dust clouds that are threaded through our galaxy. By looking at the images from Herschel, combined with those from NASA's Spitzer satellite, members of the public are invited to join the science effort by helping to distinguish between dense clumps of cold dust and holes in the dusty clouds that are threaded through our galaxy. Dust clouds don't come in simple shapes, and so the process of distinguishing between dark clouds and holes is incredibly difficult to do. Luckily, the ideal tool is at hand: the human eye. The problem proved more complex than the team had anticipated. "The problem is that clouds of interstellar dust don't come in handy easy-to-recognize shapes", Derek explained. "The images are too messy for computers to analyze, and there are too many for us to go through ourselves". This is where the Zooniverse comes in, with its community of citizen scientists poised ready to help out. The new images are part of the Milky Way Project, which launched 2 years ago and, through the efforts of over 40,000 volunteers, has already created astronomy's largest catalogue of star-forming bubbles, as well as a plethora of nearby star clusters, distant galaxies and more. The Milky Way Project volunteers are excellent at measuring and mapping our galaxy." More

A Cosmic Holiday Ornament, Hubble-Style

'Tis the season for holiday decorating and tree-trimming. Not to be left out, astronomers using NASA's Hubble Space Telescope have photographed a festive-looking nearby planetary nebula called NGC 5189. The intricate structure of this bright gaseous nebula resembles a glass-blown holiday ornament with a glowing ribbon entwined.

A new study published by University of Chicago researchers challenges the notion that the force of an exploding star forced the formation of the solar system.
