HARVARD PORTRAIT Karin Öberg

GROWING UP IN Lutheran Sweden, Karin Öberg had no inkling that she would one day become an astrochemist, the first to observe a complex organic molecule in the freezing cloud of gas and dust surrounding a young star—or that she would convert to...

A Circumplanetary Disk Candidate Spotted with ALMA

Astronomers may have found a gaseous disk around a planet orbiting the young star AS 209. This is one of just four circumplanetary disk candidates discovered so far, and these observations enable the first mass estimate of a circumplanetary disk’s gas...
This image of the AS 209 protoplanetary disk at a wavelength of 1.25 millimeters shows the thermal emission from the dust. The white line at the lower right is a 10-au scale bar and the white circle at the lower left is the beam size for the observations.

Planets Form in Organic Soups with Different Ingredients

Cambridge, MA -- Astronomers have mapped out the chemicals inside of planetary nurseries in extraordinary detail. The newly unveiled maps reveal the locations of dozens of molecules within five protoplanetary disks — regions of dust and gas where planets...
In this artists conception, planets form from the gas and dust in the protoplanetary disk surrounding a young star.

The evolving chemistry of protoplanetary disks

Planets form from the gas and dust in disks that surround young stars. Chemicals in the disk that evaporate easily, called volatiles, include important molecules like water, carbon monoxide, nitrogen, as well as other simple organic molecules. The amount...

ALMA Captures Stirred-Up Planet Factory

In recent years, high resolution observations of dust structures have revolutionized our understanding of planet formation. However, this new image of the gas indicates that the current view of planet formation is still too simplistic and that it might be...
