HH 46/47 is a complex of Herbig–Haro objects (HH objects), located around 450 parsecs (about 1,470 light-years) away in a Bok globule near the Gum nebula. Jets of partially ionized gas emerging from a young star produce visible shocks upon impact with the ambient medium. Discovered in 1977, it is one of the most studied HH objects and the ...

2023年7月26日 · NASA’s James Webb Space Telescope has captured a tightly bound pair of actively forming stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. Look for them at the center of the red diffraction spikes. The stars are buried deeply, appearing as an orange-white splotch.

Discover the HH-46 Sea Knight: Navy's VERTREP hero since 1964. Swift, powerful, and versatile, it excels in resupply missions and passenger transport, a frequent sight on aircraft carriers.

HH 46/47是一个重要的研究对象，因为它 相对年轻，只有几千年的历史。 而恒星通常需要数百万年才能完全形成。 像这样的目标 有助于研究人员深入了解恒星是如何随着时间的推移聚集质量 的，这将帮助人类研究我们的太阳这种低质量恒星是如何形成的。 数百万年后，赫比格-哈罗46/47中的恒星将完全形成，这些些壮观、色彩斑斓的喷射场景也将消失。 星座：Vela 船帆座. 距离： 1470光年. 尺寸： 7.3 角分（3.1光年） 数据：Webb 数据4441 (K. Pontoppidan). 仪器： 近红 …

2016年4月18日 · Boeing HH-46E “Phrog” Helicopter. The first Phrogs were delivered in June 1964, and entered combat in Vietnam during 1966. They served throughout the war despite being grounded for a brief time due to mechanical maladies, and over the course of the first true helicopter war, 106 leatherneck CH-46 helicopters were lost to enemy fire.

A new breed of search and rescue helicopter, the HH-46A "SEA KNIGHT" arrived at Sherman Field on 18 September 1973 marking the inception of an all-weather HSU capability and commencement of a ...

Herbig-Haro 46/47 is the colorful object at a 45-degree angle in the center. It looks like a simplified shape of a whale diving deep into the dark ocean. On the upper left is the green and bright blue “tail.”

The Young Star HH 46/47 This image from NASA's Spitzer Space Telescope transforms a dark cloud into a silky translucent veil, revealing the energetic outflow of a newborn, Sun-like star that is hidden from view to optical telescopes. Spitzer, using its sensitive infrared detectors, pierces through the dark cloud to reveal the

1999年9月21日 · We report the discovery of a pair of large Herbig-Haro type structures roughly 10 arcminutes (1.3 pc) north-east and south-west of the source driving the well-known HH 46/47 Herbig-Haro jet in new deep emission-line images made using the Wide Field Imager on the ESO/MPG La Silla 2.2-m telescope.

2003年12月18日 · HH 46/47 is a striking example of a low mass protostar ejecting a jet and creating a bipolar, or two-sided, outflow. The central protostar lies inside a dark cloud (known as a 'Bok globule') which is illuminated by the nearby Gum Nebula.
