Protostars

News & Articles

At center right is a compact star cluster composed of luminous red, blue, and white points of light. Faint jets with clumpy, diffuse material extend in various directions from the bright cluster. Above and to the right is a smaller cluster of stars. Translucent red wisps of material stretch across the scene, though there are patches and a noticeable gap in the top left corner that reveal the black background of space. Background galaxies are scattered across this swath of space, appearing as small blue-white and orange-white dots or fuzzy, thin disks. There are two noticeably larger points, foreground stars, with diffraction spikes: an orange-white point on the left, and a blue-white point in the top right.

A growing protostar embedded within a molecular cloud. The center of the image shows a bright, red region, where the growing protostar resides, with a thin, gray lane of matter cutting through it horizontally, which is the protostar’s accretion disk. Above and below this region are blue triangular-shaped molecular clouds, which give the overall object an hourglass shape. The areas in the molecular clouds closest to the protostar have more pronounced plumes of blue gas. There are red, yellow, orange, blue, and green stars and galaxies scattered across the background.

Clouds of gas and dust with many stars. The clouds form a flat, blue background toward the bottom, and become thicker and smokier toward the top. Stars on one side light the nebula. A thick arc of gas and dust reaches around from the bottom-right corner of the image toward the top-left corner. It begins as a dark and obscuring cloud at bottom right and gradually becomes brightly lit by many stars at the upper left. Other large, foreground stars lie between the nebula and the viewer.

A dark cloud of gas and dust sits along the top half of the image. The cloud is illuminated by a bright-white star below it and just to the right of image center. Another bright object, looking like a bright, vertical disk bisected by a dark cloud, sits just to the right of the main cloud and above and to the right of the bright-white star. A jet of bright, turquoise light streams to the left and right from each side of the vertical disk-like object. A section of the jet, to the left, appears to be hidden behind the dark cloud, but emerges from the cloud left of image center. The background is black with rusty hues near the bright-white star.

An image of a region of a molecular cloud. The orange cloud is dense and bright close to the top of the image, like rolling clouds, and grows darker and more wispy toward the bottom and in the top corner. One bright star with six short diffraction spikes and several dimmer stars are visible as light spots among the clouds.

A nebula with stars. The center of the image from top-left to bottom-right glows brightly with the light of newly forming stars and is partially obscured by dark dust. Colored layers of gas and dust billow out across the rest of the image. Foreground stars with large diffraction spikes speckle the nebula.

What Is the Solar Wind?

An animation shows the Sun in the bottom left corner. Cascading off the Sun are lines in every direction, representing solar wind streams. As they move away, kinks form in the lines, and grow wider as they move outward.
