IRAS 16547-4247 Artist's Concept

A research group led by Aya Higuchi, a researcher at Ibaraki University, conducted observations of the massive-star forming region IRAS 16547-4247 with the Atacama Large Millimeter/submillimeter Array (ALMA).

Herschel and Planck Find Missing Clue to Galaxy Cluster Formation

Herschel and Planck Find Missing Clue to Galaxy Cluster Formation

By combining observations of the distant Universe made with ESA's Herschel and Planck space observatories, cosmologists have discovered what could be the precursors of the vast clusters of galaxies that we see today.


Hubble Views Galaxy NGC 5023 on Edge

Hubble Views Galaxy NGC 5023 on Edge

This Hubble Space Telescope image shows an edge-on view of the spiral galaxy NGC 5023. Due to its orientation we cannot appreciate its spiral arms, but we can admire the elegant profile of its disk.


The Heart of the Large Magellanic Cloud

The Heart of the Large Magellanic Cloud

A scene of jagged fiery peaks, turbulent magma-like clouds and fiercely hot bursts of bright light. Although this may be reminiscent of a raging fire or the heart of a volcano, it actually shows a cold cosmic clump of gas, dust and stars.


Dark Matter Is Even Darker Than We Once Thought

Dark Matter Is Even Darker Than We Once Thought

Astronomers using observations from the NASA/ESA Hubble Space Telescope and NASA's Chandra X-ray Observatory have studied how dark matter in clusters of galaxies behaves when the clusters collide.


Best View Yet of Dusty Cloud Passing Galactic Center Black Hole

Best View Yet of Dusty Cloud Passing Galactic Center Black Hole

A supermassive black hole with a mass four million times that of the Sun lies at the heart of the Milky Way galaxy.


Black-hole Wind Linked To Galactic Gush of Star-forming Gas

Black-hole Wind Linked To Galactic Gush of Star-forming Gas

By combining observations from the Japan-led Suzaku X-ray satellite and the European Space Agency's infrared Herschel Space Observatory, scientists have connected a fierce "wind" produced near a galaxy's monster black hole to an outward torrent of cold gas a thousand light-years across.


Satellites Catch Growth Spurt from Newborn Protostar

Satellites Catch Growth Spurt from Newborn Protostar

Using data from orbiting observatories, including NASA's Spitzer Space Telescope, and ground-based facilities, an international team of astronomers has discovered an outburst from a star thought to be in the earliest phase of its development.


Chemical Fingerprints of Ancient Supernovae Found

Chemical Fingerprints of Ancient Supernovae Found

A Carnegie-based search of nearby galaxies for their oldest stars has uncovered two stars in the Sculptor dwarf galaxy that were born shortly after the galaxy formed, approximately 13 billion years ago.


More Than a Million Stars Forming In a Mysterious Dusty Gas Cloud

More Than a Million Stars Forming In a Mysterious Dusty Gas Cloud

More than a million young stars are forming in a hot, dusty cloud of molecular gases in a tiny galaxy near our own, an international team of astronomers has discovered.


Mini Supernova Explosion Could Have Big Impact

Mini Supernova Explosion Could Have Big Impact

In Hollywood blockbusters, explosions are often among the stars of the show. In space, explosions of actual stars are a focus for scientists who hope to better understand their births, lives, and deaths and how they interact with their surroundings.


The Debris Disk Around epsilon Eridani

The Debris Disk Around epsilon Eridani

The debris disk closest to Earth is the one around the star epsilon Eridani at a distance of 3.2 pc. It is the prime target for detailed studies of a belt of planetesimals left from the early phase of planet formation other than the Kuiper Belt.


Mysterious Phenomena in a Gigantic Galaxy-Cluster Collision

Mysterious Phenomena in a Gigantic Galaxy-Cluster Collision

Researchers using the Karl G. Jansky Very Large Array (VLA) have produced the most detailed image yet of a fascinating region where clusters of hundreds of galaxies are colliding, creating a rich variety of mysterious phenomena visible only to radio telescopes.


Unexpected Gamma-Ray Emission May Point to New Understanding of Dark Matter

Unexpected Gamma-Ray Emission May Point to New Understanding of Dark Matter

A newly discovered dwarf galaxy orbiting our own Milky Way has offered up a surprise it appears to be radiating gamma rays, according to an analysis by physicists at Carnegie Mellon, Brown and Cambridge universities.
