A number of days in the past, we noticed an enchanting snapshot of the Triffid Nebula, the 20th object found by French astronomer Charles Messier. Related celestial objects had been studied by Messier within the Catalog des nebuluses et des amas d’étoiles, and the catalog recognized right now as Messier Objects incorporates 110 objects. Over the previous few months, we have seen many superb pictures of celestial objects as a part of the NASA Astronomy Image of the Day, a every day launch that includes astrophotographers from all over the world.
At present’s NASA Astronomy image of the day A snapshot of M94, often known as the Double Ring Galaxy, incorporates greater than 40 billion stars. In accordance with NASA, the Double Ring Galaxy is positioned about 15 million light-years away towards the constellation of Canes Venati, often known as the Hound. M94 was found in 1781 by one other French astronomer named Pierre Machen and cataloged two days later by Charles Messier.

Picture description from NASA
Most galaxies haven’t any rings of stars and gasoline — why does M94 have two? First, the spiral galaxy M94 has an interior ring of newly shaped stars round its nucleus, giving it not solely an uncommon look but in addition an interior glow. A number one origin speculation posits that an elongated knot of stars generally known as a bar rotates in M94 and that this interior ring has exploded in star formation. Observations have additionally revealed one other ring, an outer ring, which is fainter, completely different in coloration, not closed, and comparatively advanced. What causes this outer ring is presently unknown. M94, pictured right here, spans a complete of about 45,000 light-years, lies about 15 million light-years away, and will be seen with a small telescope towards the constellation Canes Venatisi.
