Hubble captures the dramatic jets of a baby star

By Georgina Torbet Published March 26, 2024

A new image from the Hubble Space Telescope shows the drama that unfolds as a new star is born. Within a swirling cloud of dust and gas, a newly formed star is giving off powerful jets that blast away material and cut through the nearby dust of the surrounding nebula to create this stunning vista.

The image shows a system called FS Tau, located 450 light-years away in a region called Taurus-Auriga. Within this region are many stellar nurseries with new stars forming, making it a favorite target for astronomers studying star formation. But this particular system stands out for the dramatic nature of its newborn star, which has formed an epic structure called a Herbig-Haro object.

FS Tau is a multi-star system made up of FS Tau A, the bright star-like object near the middle of the image, and FS Tau B (Haro 6-5B), the bright object to the far right that is partially obscured by a dark, vertical lane of dust. The young objects are surrounded by softly illuminated gas and dust of this stellar nursery. The system is only about 2.8 million years old, very young for a star system. Our Sun, by contrast, is about 4.6 billion years old. — FS Tau is a multi-star system made up of FS Tau A, the bright star-like object near the middle of the image, and FS Tau B (Haro 6-5B), the bright object to the far right that is partially obscured by a dark, vertical lane of dust.

A Herbig-Haro object is the structure created by jets of material coming from a young star. A star forms from clouds of dust and gas when this material clumps together to form a small knot. Over time, this knot attracts more and more material due to gravity, until it eventually collapses to form a core and becomes a protostar. As the protostar is dense, it attracts even more material due to gravity, growing over time and getting hotter as the material rubs together, creating friction. However, the star isn’t yet creating its own heat via fusion, so it isn’t yet a main sequence star like our sun.

The growing protostar can still become very hot though, with heat generated by the collapsing of the dust cloud and the gradual accretion of matter. This heat gives the protostar enough energy to shine, even though it isn’t creating its own heat and light from fusion yet. And with this energy, the protostar can eject two superfast jets of matter, each coming from the opposite direction. These jets of gas move so quickly that they collide with nearby dust and gas to create illumination — and it’s these jets that define a Herbig-Haro object.

The object FS Tau is unusual in that the protostar is giving off an asymmetrical double-sided jet, thought to be because matter is being expelled at different rates. It is also a binary system, with the Herbig-Haro object FS Tau B making up one half of a pair of stars along with FS Tau A, the bright object near the center of this image.

There’s a tiny exoplanet orbiting our neighbor, known as Barnard’s star

Artist’s impression of a sub-Earth-mass planet orbiting Barnard’s star

In our local cosmic neighborhood, the nearest star is Proxima Centauri, which is part of the three-star Alpha Centauri system and known to host exoplanets of its own. But just a little further away is a single star on its own, known as Barnard's star. Recently, astronomers discovered that this star also hosts at least one exoplanet, and could host as many as four.

At just six light-years from Earth, Barnard's star is close by and has long been of interest to researchers searching for nearby exoplanets. But as a small, dim type of star called a red dwarf, no one has discovered an exoplanet here before -- though there were hints found in 2018 that such a planet might exist.

‘That’s weird’: This galaxy could help astronomers understand the earliest stars

The newly-discovered GS-NDG-9422 galaxy appears as a faint blur in this James Webb Space Telescope NIRCam (Near-Infrared Camera) image. It could help astronomers better understand galaxy evolution in the early Universe.

Astronomers using the James Webb Space Telescope have spotted a weird galaxy that originated just a billion years after the Big Bang. Its strange properties are helping researchers to piece together how early galaxies formed, and to inch closer to one of astronomy's holy grail discoveries: the very earliest stars.

The researchers used Webb's instruments to look at the light coming from the GS-NDG-9422 galaxy across different wavelengths, called a spectrum, and made some puzzling findings.

Polaris Dawn crew member describes the dramatic ride home

Crew Dragon Endeavour shortly before splashdown.

A crew member of SpaceX’s recent Polaris Dawn mission has described what it was like aboard the Crew Dragon spacecraft as it entered Earth’s atmosphere and hurtled toward Earth during the crew's high-speed homecoming last weekend.

Polaris Dawn’s Scott Poteet was responding to a stunning photo captured from the International Space Station (ISS) by NASA astronaut Don Pettit, which showed the Crew Dragon during its rapid descent at the end of a historic five-day mission that involved the first privately funded spacewalk.
