Planets in the Making Around Young Star HD 163296

This newly released ESO image shows a disc of rotating, leftover material surrounding the young star HD 163296. Our Solar System formed out of a huge, primordial cloud of gas and dust. The vast majority of that cloud formed the Sun, while the leftover disc of rotating material around it eventually coalesced into the orbiting […]

ALMA Reveals Potential Localized Dust Enrichment from Massive Star Clusters in II Zw 40

New observations from the Atacama Large Millimeter/submillimeter Array are helping to confirm a long-standing theory that stars are copious producers of heavy elements. Galaxies are often thought of as sparkling with stars, but they also contain gas and dust. Now, a team led by UCLA astronomers has used new data to show that stars are […]

ALMA Views a Protoplanetary Disc Surrounding the Young Star Elias 2-27

This newly released image shows a protoplanetary disc surrounding the young star Elias 2-27. This beautiful image, captured with the Atacama Large Millimeter/submillimeter Array (ALMA) features a protoplanetary disc surrounding the young star Elias 2-27, some 450 light years away. ALMA has discovered and observed plenty of protoplanetary discs, but this disc is special as […]

ALMA Views Massive Star ST11

Using the Atacama Large Millimeter/submillimeter Array, a team of astronomers reveal the first hot core to be found outside the Milky Way. A hot and dense mass of complex molecules, cocooning a newborn star, has been discovered by a Japanese team of astronomers using ALMA. This unique hot molecular core is the first of its […]

New Images of the Hubble Ultra Deep Field

Using the Atacama Large Millimeter/submillimeter Array, international teams of astronomers explore the distant corner of the Universe first revealed in the iconic images of the Hubble Ultra Deep Field (HUDF). New ALMA observations are significantly deeper and sharper than previous surveys at millimeter wavelengths. They clearly show how the rate of star formation in young […]

Astronomers Discover Record-Breaking Galaxy Cluster

Using Chandra and several other telescopes, astronomers have found the most distant galaxy cluster to date. This cluster, called CL J1001+0220, lies about 11.1 billion light years from Earth and may have been caught right after birth, a brief, but important stage of cluster evolution never seen before. The remote galaxy cluster was found in […]

Resolving the Planetesimal Belt of HR 8799

Using the ALMA submillimeter array, astronomers image the disk around HR8799 with a spatial scale as small as only thirty-two au, enough to probe the inner zones of the disk. Planets develop from the dusty placental disk of material that surrounds a star after it begins to shine. The dust in that disk, according to […]

Water Snowline Around Young Star V883 Orionis

Using the Atacama Large Millimeter/submillimeter Array (ALMA), a team of astronomers has made the first ever resolved observation of a water snow line within a protoplanetary disc. This line marks where the temperature in the disc surrounding a young star drops sufficiently low for snow to form. A dramatic increase in the brightness of the […]

Astronomers Find a Planet Forming in an Earth-like Orbit around a Young Star

Using data from the Atacama Large Millimeter/submillimeter Array, astronomers reveal a planet-forming disk in unprecedented detail, revealing a series of concentric dusty bright rings and dark gaps, including intriguing features that suggest a planet with an Earth-like orbit is forming there. Disks of dust and gas that surround young stars are the formation sites of […]

ALMA Views a Transitional Disc around a New Star

Using the Atacama Large Millimeter/submillimeter Array, astronomers have found telltale differences between the gaps in the gas and the dust in discs around four young stars. These new observations are the clearest indications yet that planets with masses several times that of Jupiter have recently formed in these discs. Planets are found around nearly every […]

ALMA Reveals Planetary Influences on Young Stellar Disks

New research from the Harvard-Smithsonian Center for Astrophysics shows that the gas cavity in transition disks in four young stars was as much as three times smaller than the dust cavity, and that the gas density inside the cavity drops by at least a factor of one thousand compared to the surface density. A newborn […]

ALMA Reveals Ultracool Star That is Super Stormy

Using the Atacama Large Millimeter/submillimeter Array, astronomers reveal that red dwarf star TVLM 513-46546 has an amazingly powerful magnetic field. Our Sun is a relatively quiet star that only occasionally releases solar flares or blasts of energetic particles that threaten satellites and power grids. You might think that smaller, cooler stars would be even more […]

ALMA Views Assembly of Galaxies in the Early Universe

New observations from the Atacama Large Millimeter/submillimeter Array reveal the most distant clouds of star-forming gas yet found in normal galaxies in the early Universe. The new images allow astronomers to start to see how the first galaxies were built up and how they cleared the cosmic fog during the era of reionization. This is […]

ALMA Identifies Gas Spirals as a Nursery of Twin Stars

Astronomers used observations from the Atacama Large Millimeter/submillimeter Array to identify spiral arms of molecular gas and dust around binary protostars, revealing for the first time the mechanism of the birth and growth of binary stars. Overview With the Atacama Large Millimeter/submillimeter Array (ALMA) observation, astronomers led by Shigehisa Takakuwa, Associate Research Fellow at the […]
