Ophiuchus

Constellation known as the serpent bearer, contains Barnard 68, a molecular cloud, and seven Messier objects.

Barnard 68

Dark molecular cloud, 500 light-years away, important for star formation, discovered by Edward E. Barnard in 1919.

Orion

Constellation discovered by Christiaan Huygens, contains FU Orionis, a pre-main-sequence star with extreme variability.

HOPS 383

Class 0 protostar, 100,000 years old, located about 1,400 light years from Earth, known for having an outburst.

Messier 42

The Orion Nebula, a cloud of dust and gas where new stars are formed, discovered by Christiaan Huygens, 1,344 light years away.

Pegasus

Constellation in the Northern Hemisphere, part of the Perseus family, discovered by Ptolemy, contains Messier 15 and stars with confirmed planets.

Stephan's Quintet

Visual grouping of five galaxies, four forming the first compact galaxy group discovered.

Stephan's Quintet

A group of interacting galaxies that trigger star formation in each other, providing insights into fundamental galactic processes.

NGC 1333

A reflection nebula in Perseus containing young stars less than a million years old, hidden by stardust, offering a glimpse into early stellar evolution.

Hickson Compact Group 92 (HCG 92)

Refers to the four galaxies clumped closely together in Stephan's Quintet, serving as a unique astronomical system for study.

Baby Boom Galaxy

A massive elliptical starburst galaxy undergoing intense star formation, emitting light primarily in the infrared spectrum.

HL Tauri

A T Tauri star in Taurus, representing an early stage in stellar evolution with a mass similar to the Sun, crucial for understanding star formation.

L1527

A class 0 protostar located 460 light-years away, providing a rare example of such objects and aiding in the study of stellar evolution.

NGC 1555

Also known as Hind's Variable Nebula, a variable nebula illuminated by T Tauri, showcasing early stellar evolution and Herbig–Haro objects.

T Tauri

The first young star discovered with a mass similar to the Sun, representing a class of very young stars characterized by erratic brightness changes.

HH 46/47

Herbig–Haro objects located in Vela, offering insights into early star formation processes and emitting light in specific sections of the electromagnetic spectrum.

RCW 38

An HII region in Vela containing a massive star cluster, crucial for studying star formation with O type stars and forming insights into early stellar evolution.

Objects in Volans

Notable deep sky objects in Volans include the Lindsay-Shapley Ring (AM0644-741), the Meathook Galaxy (NGC 2442), the spiral galaxy NGC 2397, and the galaxy cluster SMACS 0723.

Discovery of Volans objects

Discovered in the late 16th century by Pieter Dirkszoon Keyser and Frederick de Houtman.

J122051+491255

A green pea galaxy.

Green pea galaxy

A small, green-blue galaxy with high luminosity due to intense star formation.

Importance of green pea galaxies

They exhibit high rates of star formation.

Spectral uniqueness of green pea galaxies

They have low oxygen levels compared to the Milky Way, making them chemically primitive.
