It was discovered by William Herschel on September 11, 1784. This is a site where new stars are being born in a spiral arm of the galaxy. Though such nebulae are common in galaxies, this one is particularly large, nearly 1,500 lightyears across. The nebula is so vast it is easily seen in ground-based telescopic images. At the heart of NGC 604 are over 200 hot stars, much more massive than our Sun (15 to 60 solar masses). They heat the gaseous walls of the nebula making the gas flouresce. Their light also highlights the nebula's three-dimensional shape, like a lantern in a cavern. By studying the physical structure of a giant nebula, astronomers may determine how clusters of massive stars affect the evolution of the interstellar medium of the galaxy. The nebula also yields clues to its star formation history and will improve understanding of the starburst process when a galaxy undergoes a "firestorm" of star formation.

From James Kaler's Star Notes: Mothallah is from the Arabic meaning simply "the triangle." Residing in yellowwhite class F, Mothallah has a temperature of 6,350 Kelvin, only 10% greater than the solar temperature. It is only three times larger than the Sun. More advanced in relative age than the Sun, Mothallah is a 1.5 solar mass "subgiant," that is close to shutting down its core hydrogen fusion, if it has not done so already, as it prepares to be a giant star. Yet because stars of higher mass live shorter lives, Mothallah is only about 2.7 billion years old, as compared with the 4.5 billion year age of the Sun. Mothallah is observed to shift back and forth, telling us that it is accompanied by a small companion about which nothing is known. The system is odd because the orbital period of the companion around Mothallah proper is very short, a mere 1.74 days. (Even Mercury takes 88 days to go around the Sun). The separation between them must be very small, perhaps around 0.04 times the distance between the Earth and Sun. Given Mothallah's size, the companion is only around three million kilometers from Mothallah's surface. Seen from the companion, Mothallah would be an immense 45 degrees across. The closeness would probably not preclude planets, which could orbit at such a distance that any residents would see a "double sun." - 28 - Zone 107 Double Stars Easy STF 172 SAO 74962 Rating: 3 E Position: 0150+2706 A B Magnitude 10.24 10.39 Separation PA — — 17.8 + 194 - Year — 1991 Spectra F8 IV Colors W W Notes: 1830: 17.5 @ 195. 12 measurements.
