Astronomers using the NASA/ESA Hubble Space Telescope have captured a detailed image of a spectacular part of IC 438, a spiral galaxy located in the constellation of Lepus.
IC 438 resides approximately 130 million light-years away in the constellation of Lepus.
“Lepus lies just south of the celestial equator (the ring around the middle of Earth that falls at right angles to its rotation axis),” the Hubble astronomers said.
“Appropriately, Lepus is flanked by the constellations Canis Major (the Greater Dog) and Orion (the Hunter), whilst Canis Minor (the Lesser Dog) lies very nearby, meaning that in artistic representations of the constellations, Lepus is often shown as being pursued by Orion and his two hunting dogs.”
“Lepus is one of the 88 constellations that are officially recognized by the International Astronomical Union (IAU).”
“It is worth clarifying that, whilst the actual constellations themselves only comprise a handful of stars, the area of sky covered by those stars is often referred to using the name of the constellation.”
“For example, when we say that IC 438 is in Lepus, we do not mean that the galaxy is part of the constellation — perhaps obviously, as it is not a single star, but an entire galaxy!”
“Rather, we mean that it falls in the region of sky covered by the Lepus constellation stars.”
“The IAU’s 88 official constellations are by no means the only constellations ever described by humanity,” they said.
“Humans have been studying and naming the stars for a very long time, and different cultures of course have their own constellations.”
“The IAU constellations are Eurocentric, with many taken from Ptolemy’s list of constellations.”
“Collectively, the 88 constellations divide the night sky into 88 regions which completely cover it, so that the approximate location of any celestial object can be described using one of the 88.”
IC 438 was discovered on January 7, 1891 by the American astronomer…
