The blue clusters in the picture are the Herbig–Haro objects numbered 7 to 11 (HH 7–11), and they’re located within NGC 1333, a reflection nebula full of dust and gas found roughly 1,000 light-years away from our planet.#HubbleFriday Hubble has captured the smoking gun of a newborn star! These five objects, visible in blue in the top center of the image, lie within NGC 1333, a reflection nebula full of gas and dust found about a thousand light-years away from Earth:— Hubble (@NASAHubble) February 15, 2019Herbig-Haro objects are transient phenomena located near newborn stars. They travel away from the star that created them at a speed up to 150,000 miles per hour and vanish into the cosmos within a few tens of thousands of years.According to NASA, the young star that is the source of these Herbig-Haro objects is called SVS 13, and in the image, the bright blue clusters are moving away from SVS 13 toward the upper left side. The distance between HH 7 and SVS 13 is roughly 20,000 times the distance between the sun and Earth.Herbig-Haro objects are developed by a complex process: Jets of ionized gas are thrown out by a young star and they bang into nearby clouds of dust and gas at high speeds, causing these eerie, bright blue clusters to form deep in the cosmos.Watch this NASA YouTube Video to see Herbig-Haro objects in action and how they’re ejected from young stars:More on’s SPHEREx Mission Will Explore Origins of UniverseNASA’s Insight Lander Deployed Second Instrument on MarsNASA Says Goodbye to Its Mars Opportunity Rover Stay on targetlast_img
