A small section of the Veil Nebula, the debris of a supernova remnant formed roughly 8, years ago by the death of a star 20 times the mass of our sun.
In this image, red corresponds to hydrogen, green to sulfur, and blue to oxygen. This image of the red supergiant star V Monocerotis reveals dramatic changes in the illumination of its surrounding dust clouds.
SpécificationsThe effect, called a light echo, unveiled never-before-seen dust patterns when the star suddenly brightened in January It temporarily became one of the brightest stars in the Milky Way—, times brighter than our sun—before fading in April In contrast to a normal nova explosion, V Monocerotis did not expel its outer layers, NASA reported. Instead, it ballooned in size, and its surface temperature dropped to temperatures not much hotter than a light bulb.
Newly formed stars sometimes shoot out thin, hot jets of ionized gas, creating a lightsaber-like effect known as a Herbig-Haro object. The young star obscured by dust at the center of this image lies in our own Milky Way, some 1, light-years away. Hubble observed this HH object in infrared; according to NASA, these young stellar jets https://mister-baches.com/3-slot-machine/colonybet-ortak-site-20.php be ideal targets for the JWST, which will have even greater infrared wavelength vision to see deeper into the dust surrounding newly forming stars.

As smaller stars die, they eject their outer layers of gas into space over the course of about 10, years, leaving behind a hot core known as a white dwarf.
Radiation from the white dwarf at the center of this image illuminates the departing gas, creating a striking formation called a planetary nebula. According to NASAthe name comes from the early days of astronomy, when observers thought the dim forms they observed might be related to planets.
With an estimated surface temperature of more hubblebet Olaybahis İncelemesidegrees Fahrenheit, the central star of this planetary nebula is one of the hottest stars on record.

Inthere are few bright clouds on Neptune, and its distinct blue with a singular large dark spot is very reminiscent of what Voyager 2 saw in The Hubble Space Telescope is a project of international cooperation between NASA and ESA European Space Agency. The Space Telescope Science Institute STScI in Baltimore, Maryland, conducts Hubble science operations.
