In the constellation Cepheus
The Iris Nebula, also NGC 7023 and Caldwell 4, is a bright reflection nebula and Caldwell object in the constellation Cepheus. NGC 7023 is actually the cluster within the nebula, LBN 487, and the nebula is lit by a magnitude +7 star, SAO 19158.
It shines at magnitude +6.8. It is located near the Mira-type variable star T Cephei, and near the bright magnitude +3.23 variable star Beta Cephei (Alphirk). It lies 1,300 light-years away and is six light-years across.

Norma is a small constellation in the Southern Celestial Hemisphere between Scorpius and Centaurus, one of twelve drawn up in the 18th century by French astronomer Nicolas Louis de Lacaille and one of several depicting scientific instruments.
Its name is Latin for normal, referring to a right angle, and is variously considered to represent a rule, a carpenter’s square, a set square or a level. It remains one of the 88 modern constellations.
Making the most of seeing the magnificent Orion Constellation in the last week. The most distinctive and interesting of all the constellations in the Northern Hemisphere.
Starting with Betelgeuse (or beetlejuice if you prefer! )
Always new things being discovered – Result for Betelgeuse then!
Only last month, the speed of the star has been questioned – Post on Phys Site, December 2016.
I’m always so pleased to see it back in the sky!
The Cone Nebula In Monoceros Constellation.
Clear view of Orion tonight with the naked eye. Looking left from Betelguise in Orion, is the Cone Nebula.
I know I am looking at it but I don’t have a telescope. That’s why I love …astronomy.
Eridanus is a constellation in the southern hemisphere. It is represented as a river. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. It is the sixth largest of the modern constellations. The same name was later taken as a Latin name for the real Po River and also for the name of a minor river in Athens.
Eridanus contains the galaxies NGC 1232, NGC 1234, NGC 1291 and NGC 1300, a grand design barred spiral galaxy.
constellation fascination
The night sky is getting darker earlier in the evening right now so it’s time to see the constellations of the northern hemisphere in good ‘view’.
See other resources for those by viewing further on as I am not looking through a telescope, just looking up and seeing clouds!

Realistic take on the solar system subject.
A relief from scary fekking clowns take a lookup above instead for some real inspiration.
Is a Silver Coin a Silver Dollar? Neither, it’s galaxy NGC 253.
Leo in the night sky unfounded again due to cloud mass
A dark nebula or absorption nebula is a type of interstellar cloud that is so dense it obscures the light from objects behind it, such as background stars and emission or reflection nebulae.
The Sun is a magnetically active star. It supports a strong, changing magnetic field that varies year-to-year and reverses direction about every eleven years around solar maximum.
The Sun’s magnetic field leads to many effects that are collectively called solar activity, including sunspots on the surface of the Sun, solar flares, and variations in solar wind that carry material through the Solar System.
The effects of solar activity on Earth include auroras at moderate to high latitudes and the disruption of radio communications and electric power. Solar activity is thought to have played a large role in the formation and evolution of the Solar System. Solar activity changes the structure of Earth’s outer atmosphere.
All matter in the Sun is in the form of gas and at high temperatures, plasma. This makes it possible for the Sun to rotate faster at its equator (about 25 days) than it does at higher latitudes (about 35 days near its poles). The differential rotation of the Sun’s latitudes causes its magnetic field lines to become twisted together over time, producing magnetic field loops to erupt from the Sun’s surface and trigger the formation of the Sun’s dramatic sunspots and solar prominences (see Magnetic reconnection).
This twisting action creates the solar dynamo and an 11-year solar cycle of magnetic activity as the Sun’s magnetic field reverses itself about every 11 years.
this galaxy is intermediate – lenticular
A lenticular galaxy is a type of galaxy which is intermediate between an elliptical galaxy and a spiral galaxy in galaxy morphological classification schemes. Lenticular galaxies are disc galaxies (like spiral galaxies) which have used up or lost most of their interstellar matter and therefore have very little ongoing star formation.
They may, however, retain significant dust in their disks. As a…
