![]() Hubble captured an enormous bubble being blown into space by a super-hot, massive star. The Milky Way’s bulge is a crowded and dynamic region of variously aged stars zipping around at different speeds at the heart of our galaxy. Hubble captured exquisite views of Saturn’s ring system and atmospheric details that once could only be provided by spacecraft visiting the distant world. Stars are being born deep inside the so-called Pillars of Creation, which are made of cold hydrogen gas laced with dust. ![]() The newborn star in Herbig-Haro 24 (HH 24) is hidden from direct view, but jets blasting out along its rotation axis create a series of glowing shock fronts, revealing the new star’s presence. The Lagoon Nebula, a vast stellar nursery located 4,000 light-years away, provides an extraordinary tapestry of star birth. The blue ring of glowing oxygen at left is the neighboring nebula NGC 2020, formed by a torrential gaseous outflow from a lone, massive, super-hot star at its center. ![]() ![]() Hubble reveals a colorful landscape of iridescent gases, streamers of dust, and brilliant, newborn stars in the giant red nebula NGC 2014.

Interstellar distances can also be measured in parsecs. Solar system are usually measured in Astronomical Units (AU). The physical distance from Earth to the astronomical object. One of 88 recognized regions of the celestial sphere in which the object appears. Right ascension – analogous to longitude – is one component of an object's position.ĭeclination – analogous to latitude – is one component of an object's position. ![]() Morse (BoldlyGo Institute) KeywordsĪ name or catalog number that astronomers use to identify an astronomical object. Wherever the ultraviolet light strikes the dense dust, it leaves a long, thin shadow that extends beyond the lobe into the surrounding gas.Įta Carinae resides 7,500 light-years away.Ĭredits NASA, ESA, N. These streaks are created when the star's light rays poke through the dust clumps scattered along the bubble's surface. The streaks visible in the blue region outside the lower-left lobe are a striking feature in the image. The luminous magnesium resides in the space between the dusty bipolar bubbles and the outer shock-heated nitrogen-rich filaments (shown in red). Now, using Hubble's Wide Field Camera 3 to probe the nebula in ultraviolet light, astronomers have uncovered the glow of magnesium embedded in warm gas (shown in blue) in places they had not seen it before. The star, the largest member of a double-star system, has been prone to violent outbursts, including an episode in the 1840s during which ejected material formed the bipolar bubbles seen here. Telescopes such as Hubble have monitored the super-massive star for more than two decades. This Hubble Space Telescope image of the giant, petulant star Eta Carinae is yielding new surprises.
