Hubble spots a massive star forming amid clouds of dust and gas

A stunning new image from the Hubble Space Telescope shows the birth of a new, massive star at around 30 times the mass of our sun. Nestled with a nearby star-forming region called IRAS 16562-3959, the baby star is located within our galaxy and around 5,900 light-years from Earth.

You can see the sparkle of bright stars throughout the image, with the star-forming region visible as the orange-colored clouds of dust and gas stretching diagonally across the frame. These clouds are where dust and gas clump together to form knots, gradually attracting more dust and gas, growing over time to become protostars.

 This image from the NASA/ESA Hubble Space Telescope is a relatively close star-forming region known as IRAS 16562-3959.

“Observations from Hubble’s Wide Field Camera 3 make up this image,” NASA explains in a release. “Its detailed nuance of color is the result of four separate filters. These thin slivers of highly specialized material can slide in front of the instrument’s light sensors, allowing very specific wavelengths of light to pass through with each observation. This is useful because certain wavelengths of light can tell us about the region’s composition, temperature, and density.”

Much of the dust and gas in the image glows brightly in the visible light and near-infrared wavelengths in which Hubble’s instruments operate. However, there are dark regions in the area, such as the black spot toward the top left of the image. These regions aren’t actually empty, however — they are, in fact, full of dust. There is so much dust in the regions that it is blocking out the near-infrared light, making them opaque. Despite this, scientists have reason to believe that there is a massive star at the center of this region because they can see the powerful jets of material that it is throwing off, which sculpt the area by pushing away the dust and gas.

Young protostars can give off enormously powerful jets as they develop, and over time, they continue to attract more dust and increase in mass until their cores reach a temperature of around 10 million degrees Kelvin. At this temperature, they begin to fuse hydrogen and become a full adult star, called a main sequence star.

Hubble captures a formation of galaxies neatly lined up
An interacting galaxy system known as Arp-Madore 2105-332, that lies about 200 million light-years from Earth in the constellation Microscopium.

Sometimes, Hubble or other telescopes will capture two or more galaxies that are in the process of merging -- called interacting galaxies. These huge collisions can warp one or both of the galaxies, twisting them into strange shapes. The results of such collisions can be catastrophic, with one of the galaxies being destroyed. Or they can be creative, with one larger galaxy being formed from the two merging galaxies.

However, sometimes galaxies that appear very close in images are not actually interacting. Sometimes, they merely appear to be close when seen from Earth, but they can actually be thousands of light-years apart. That's the case with a previous Hubble image showing two overlapping galaxies.

James Webb spots tiniest known brown dwarf in stunning star cluster
The central portion of the star cluster IC 348. Astronomers combed the cluster in search of tiny, free-floating brown dwarfs.

A new image from the James Webb Space Telescope shows a stunning view of a star cluster that contains some of the smallest brown dwarfs ever identified. A brown dwarf, also sometimes known as a failed star, is an object halfway between a star and a planet -- too big to be a planet but not large enough to sustain the nuclear fusion that defines a star.

It may sound surprising, but the definition of when something stops being a planet and starts being a star is, in fact, a little unclear. Brown dwarfs differ from planets in that they form like stars do, collapsing due to gravity, but they don't sustain fusion, and their size can be comparable to large planets. Researchers study brown dwarfs to learn about what makes the difference between these two classes of objects.

Hubble Space Telescope is back up and running following gyro problem
Hubble orbiting more than 300 miles above Earth as seen from the space shuttle.

The Hubble Space Telescope is back to full operations after spending several weeks in safe mode due to a problem with one of its components. The telescope first experienced issues with one of its gyros on November 19, and was in and out of safe mode several times in the following days. It has remained in safe mode since November 23, but came back online on Friday, December 8.

The problem was caused by one of the telescope's three operational gyros, which are devices that help to point the telescope in the right direction. Although it would have been possible to operate the telescope with just one of these, that would have resulted in lost observing time as it would take longer to move the telescope to a new target between observations. With all three gyros now back in use, the telescope has returned to science operations.
