Alignment of bipolar jets confirms star formation theories<\/em><\/strong><\/p>\n

For the first time, a phenomenon astronomers have long hoped to directly image has been captured by NASA\u2019s James Webb Space Telescope\u2019s Near-Infrared Camera (NIRCam). In this stunning image of the Serpens Nebula, the discovery lies in the northern area (seen at the upper left) of this young, nearby star-forming region.<\/p>\n

Astronomers found an intriguing group of protostellar outflows, formed when jets of gas spewing from newborn stars collide with nearby gas and dust at high speeds. Typically these objects have varied orientations within one region. Here, however, they are slanted in the same direction, to the same degree, like sleet pouring down during a storm.<\/p>\n

In this image of the Serpens Nebula from NASA\u2019s James Webb Space Telescope, astronomers found a grouping of aligned protostellar outflows within one small region (the top left corner). Serpens is a reflection nebula, which means it\u2019s a cloud of gas and dust that does not create its own light, but instead shines by reflecting the light from stars close to or within the nebula. <\/div>\n<\/figcaption><\/div>\n<\/div>\n<\/div>\n

The discovery of these aligned objects, made possible due to Webb\u2019s exquisite spatial resolution and sensitivity in near-infrared wavelengths, is providing information into the fundamentals of how stars are born.<\/p>\n

\u201cAstronomers have long assumed that as clouds collapse to form stars, the stars will tend to spin in the same direction,\u201d said principal investigator Klaus Pontoppidan, of NASA\u2019s Jet Propulsion Laboratory in Pasadena, California. \u201cHowever, this has not been seen so directly before. These aligned, elongated structures are a historical record of the fundamental way that stars are born.\u201d<\/p>\n

So just how does the alignment of the stellar jets relate to the rotation of the star? As an interstellar gas cloud crashes in on itself to form a star, it spins more rapidly. The only way for the gas to continue moving inward is for some of the spin (known as angular momentum) to be removed. A disk of material forms around the young star to transport material down, like a whirlpool around a drain. The swirling magnetic fields in the inner disk launch some of the material into twin jets that shoot outward in opposite directions, perpendicular to the disk of material.<\/p>\n

In the Webb image, these jets are signified by bright clumpy streaks that appear red, which are shockwaves from the jet hitting surrounding gas and dust. Here, the red color represents the presence of molecular hydrogen and carbon monoxide.<\/p>\n

\u201cThis area of the Serpens Nebula \u2013 Serpens North \u2013 only comes into clear view with Webb,\u201d said lead author Joel Green of the Space Telescope Science Institute in Baltimore. \u201cWe\u2019re now able to catch these extremely young stars and their outflows, some of which previously appeared as just blobs or were completely invisible in optical wavelengths because of the thick dust surrounding them.\u201d<\/p>\n

Astronomers say there are a few forces that potentially can shift the direction of the outflows during this period of a young star\u2019s life. One way is when binary stars spin around each other and wobble in orientation, twisting the direction of the outflows over time.<\/p>\n

Stars of the Serpens<\/h2>\n

The Serpens Nebula, located 1,300 light-years from Earth, is only one or two million years old, which is very young in cosmic terms. It\u2019s also home to a particularly dense cluster of newly forming stars (~100,000 years old), seen at the center of this image. Some of these stars will eventually grow to the mass of our Sun.<\/p>\n

\u201cWebb is a young stellar object-finding machine,\u201d Green said. \u201cIn this field, we pick up sign posts of every single young star, down to the lowest mass stars.\u201d<\/p>\n

\u201cIt\u2019s a very complete picture we\u2019re seeing now,\u201d added Pontoppidan.<\/p>\n

So, throughout the region in this image, filaments and wisps of different hues represent reflected starlight from still-forming protostars within the cloud. In some areas, there is dust in front of that reflection, which appears here with an orange, diffuse shade.<\/p>\n

This region has been home to other coincidental discoveries, including the flapping \u201cBat Shadow,\u201d which earned its name when 2020 data from NASA\u2019s Hubble Space Telescope revealed a star\u2019s planet-forming disk to flap, or shift. This feature is visible at the center of the Webb image.<\/p>\n

Future Studies<\/h2>\n

The new image, and serendipitous discovery of the aligned objects, is actually just the first step in this scientific program. The team will now use Webb\u2019s NIRSpec (Near-Infrared Spectrograph) to investigate the chemical make-up of the cloud.<\/p>\n

The astronomers are interested in determining how volatile chemicals survive star and planet formation. Volatiles are compounds that sublimate, or transition from a solid directly to a gas, at a relatively low temperature \u2013 including water and carbon monoxide. They\u2019ll then compare their findings to amounts found in protoplanetary disks of similar-type stars.<\/p>\n

\u201cAt the most basic form, we are all made of matter that came from these volatiles. The majority of water here on Earth originated when the Sun was an infant protostar billions of years ago,\u201d Pontoppidan said. \u201cLooking at the abundance of these critical compounds in protostars just before their protoplanetary disks have formed could help us understand how unique the circumstances were when our own solar system formed.\u201d<\/p>\n

These observations were taken as part of General Observer program 1611. The team\u2019s initial results have been accepted in the Astrophysical Journal.<\/p>\n

The James Webb Space Telescope is the world\u2019s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).<\/em><\/p>\n<\/p>\n
