In 1993, the Hubble Space Telescope first observed the Orion Nebula.
Since then, the nebula has been a frequent target for HST studies.
The star appears fuzzy to sharp-eyed observers, and the nebulosity is obvious through binoculars or a small telescope.
Protoplanetary disks have been observed around most of the newly formed stars in the nebula, and the destructive effects of high levels of ultraviolet energy from the most massive stars have been studied.
In 1902, Vogel and Eberhard discovered differing velocities within the nebula and by 1914 astronomers at Marseilles had used the interferometer to detect rotation and irregular motions.
Campbell and Moore confirmed these results using the spectrograph, demonstrating turbulence within the nebula. Trumpler noted that the fainter stars near the Trapezium formed a cluster, and he was the first to name them the Trapezium cluster.
Messier published the first edition of his catalog of deep sky objects in 1774 (completed in 1771).
On September 30, 1880 Henry Draper used the new dry plate photographic process with an 11-inch (28 cm) refracting telescope to make a 51-minute exposure of the Orion Nebula, the first instance of astrophotography of a nebula in history.
